Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

Lead and Lag functions in SQL Server 2012
 
07:27
In this video we will discuss about Lead and Lag functions. Lead and Lag functions Introduced in SQL Server 2012 Lead function is used to access subsequent row data along with current row data Lag function is used to access previous row data along with current row data ORDER BY clause is required PARTITION BY clause is optional Syntax LEAD(Column_Name, Offset, Default_Value) OVER (ORDER BY Col1, Col2, ...) LAG(Column_Name, Offset, Default_Value) OVER (ORDER BY Col1, Col2, ...) Offset - Number of rows to lead or lag. Default_Value - The default value to return if the number of rows to lead or lag goes beyond first row or last row in a table or partition. If default value is not specified NULL is returned. We will use the following Employees table for the examples in this video SQL Script to create the Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10), Salary int ) Go Insert Into Employees Values (1, 'Mark', 'Male', 1000) Insert Into Employees Values (2, 'John', 'Male', 2000) Insert Into Employees Values (3, 'Pam', 'Female', 3000) Insert Into Employees Values (4, 'Sara', 'Female', 4000) Insert Into Employees Values (5, 'Todd', 'Male', 5000) Insert Into Employees Values (6, 'Mary', 'Female', 6000) Insert Into Employees Values (7, 'Ben', 'Male', 7000) Insert Into Employees Values (8, 'Jodi', 'Female', 8000) Insert Into Employees Values (9, 'Tom', 'Male', 9000) Insert Into Employees Values (10, 'Ron', 'Male', 9500) Go Lead and Lag functions example WITHOUT partitions : This example Leads 2 rows and Lags 1 row from the current row. When you are on the first row, LEAD(Salary, 2, -1) allows you to move forward 2 rows and retrieve the salary from the 3rd row. When you are on the first row, LAG(Salary, 1, -1) allows us to move backward 1 row. Since there no rows beyond row 1, Lag function in this case returns the default value -1. When you are on the last row, LEAD(Salary, 2, -1) allows you to move forward 2 rows. Since there no rows beyond the last row 1, Lead function in this case returns the default value -1. When you are on the last row, LAG(Salary, 1, -1) allows us to move backward 1 row and retrieve the salary from the previous row. SELECT Name, Gender, Salary, LEAD(Salary, 2, -1) OVER (ORDER BY Salary) AS Lead_2, LAG(Salary, 1, -1) OVER (ORDER BY Salary) AS Lag_1 FROM Employees Lead and Lag functions example WITH partitions : Notice that in this example, Lead and Lag functions return default value if the number of rows to lead or lag goes beyond first row or last row in the partition. SELECT Name, Gender, Salary, LEAD(Salary, 2, -1) OVER (PARTITION By Gender ORDER BY Salary) AS Lead_2, LAG(Salary, 1, -1) OVER (PARTITION By Gender ORDER BY Salary) AS Lag_1 FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/lead-and-lag-functions-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/lead-and-lag-functions-in-sql-server_5.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

SQL: TRIM function
 
06:35
In this tutorial, you'll learn how to use trim function PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

ASCII Function in SQL Query with Example
 
01:33
ASCII(): ASCII function returns the NUMBER code that represents the specified character. Sytax: ASCII( single_character ) PARAMETERS: single_character is the specified character to retrieve the NUMBER code for. If more than one character is entered, the ASCII function will return the value for the first character and ignore all of the characters after the first. Let's look at some Oracle ASCII function examples and explore how you would use the ASCII function in Oracle/PLSQL. For example: ASCII('C') would return 67 ASCII('T') would return 84 ASCII('T2') would also return 84 Thanks for watching...:)

Oracle 12c New Feature Spotlight Synchronous Refresh for Materialized Views
 
54:18
Materialized views can perform a number of roles, such as improving query performance or providing replicated data. Prior to Oracle 12c, materialized views used traditional refresh methods where changes were applied to the base tables and then the materialized views were refreshed separately with one of several methods. Synchronous refresh is a new approach in Oracle 12c R1 for maintaining tables and materialized views where tables and materialized views are refreshed at the same time. This webinar will discuss the benefits of the synchronous refresh method along with how to implement it.

GROUPING ID function in SQL Server
 
12:38
grouping_id function in sql server 2008 grouping_id in sql server 2008 example sql server grouping level In this video we will discuss 1. GROUPING_ID function in SQL Server 2. Difference between GROUPING and GROUPING_ID functions 3. Use of GROUPING_ID function GROUPING_ID function computes the level of grouping. Difference between GROUPING and GROUPING_ID Syntax : GROUPING function is used on single column, where as the column list for GROUPING_ID function must match with GROUP BY column list. GROUPING(Col1) GROUPING_ID(Col1, Col2, Col3,...) GROUPING indicates whether the column in a GROUP BY list is aggregated or not. Grouping returns 1 for aggregated or 0 for not aggregated in the result set. GROUPING_ID() function concatenates all the GOUPING() functions, perform the binary to decimal conversion, and returns the equivalent integer. In short GROUPING_ID (A, B, C) = GROUPING(A) + GROUPING(B) + GROUPING(C) Let us understand this with an example. SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, CAST(GROUPING(Continent) AS NVARCHAR(1)) + CAST(GROUPING(Country) AS NVARCHAR(1)) + CAST(GROUPING(City) AS NVARCHAR(1)) AS Groupings, GROUPING_ID(Continent, Country, City) AS GPID FROM Sales GROUP BY ROLLUP(Continent, Country, City) Row Number 1 : Since the data is not aggregated by any column GROUPING(Continent), GROUPING(Country) and GROUPING(City) return 0 and as result we get a binar string with all ZEROS (000). When this converted to decimal we get 0 which is displayed in GPID column. Row Number 7 : The data is aggregated for Country and City columns, so GROUPING(Country) and GROUPING(City) return 1 where as GROUPING(Continent) return 0. As result we get a binar string (011). When this converted to decimal we get 10 which is displayed in GPID column. Row Number 15 : This is the Grand total row. Notice in this row the data is aggregated by all the 3 columns. Hence all the 3 GROUPING functions return 1. So we get a binary string with all ONES (111). When this converted to decimal we get 7 which is displayed in GPID column. Use of GROUPING_ID function : GROUPING_ID function is very handy if you want to sort and filter by level of grouping. Sorting by level of grouping : SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING_ID(Continent, Country, City) AS GPID FROM Sales GROUP BY ROLLUP(Continent, Country, City) ORDER BY GPID Filter by level of grouping : The following query retrieves only continent level aggregated data SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING_ID(Continent, Country, City) AS GPID FROM Sales GROUP BY ROLLUP(Continent, Country, City) HAVING GROUPING_ID(Continent, Country, City) = 3 Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/groupingid-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/groupingid-function-in-sql-server_27.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

SQL String Functions PART  -- 1
 
17:23
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). ... The most basic example of a string function is the length(string) function. This function returns the length of a string literal.Scalar-valued UDFs are an easy way to define constant values to use in your database environment. You can pass field values as parameters into UDFs. You can nest scalar function calls. This means that you can pass a call to a scalar-valued function to another function or stored procedure.Numeric functions perform manipulation of numbers that normally are contained in a table column. ... Returns a numeric value, rounded to the specified length or precision. SIGN() SQL server, MySQL, Oracle, PostgreSQL. Returns the positive (+1), zero (0), or negative (-1) sign of a numeric expression.A stored function (also called a user function or user-defined function) is a set of PL/SQL statements you can call by name. Stored functions are very similar to procedures, except that a function returns a value to the environment in which it is called. User functions can be used as part of a SQL expression.Function must return a value but in Stored Procedure it is optional( Procedure can return zero or n values). Functions can have only input parameters for it whereas Procedures can have input/output parameters . ... Functions can be called from Procedure whereas Procedures cannot be called from Function,The CTE was introduced into standard SQL in order to simplify various classes of SQL Queries for which a derived table just wasn't suitable. ... Introduced in SQL Server 2005, the common table expression (CTE) is a temporary named result set that you can reference within a SELECT, INSERT, UPDATE, or DELETE statement.The isDate(string, string) function accepts two string arguments. It takes them, compares the first argument with the second as a pattern and, if the first string can be converted to a date which is valid within system value of locale , according to the specified pattern , the function returns true.printf does the same, treating %s as a pointer-to-string. In C, variables that are arrays become a pointer to the first element of the array when used as function arguments -- so your scanf() sees a pointer to memory (assuming "str1" is an array). SQL - Useful Functions SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. More items... SQL has many built-in functions for performing processing on string or numeric data. Following is the list of all useful SQL built-in functions − SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. SQL MIN Function - The SQL MIN aggregate function allows us to select the lowest (minimum) value for a certain column. SQL - The SQL AVG aggregate function selects the average value for certain table column. SQL SUM Function - The SQL SUM aggregate function allows selecting the total for a numeric column.

Oracle 11g Enterprise Protection using Double-Take Availability 5.2 (FSF)
 
09:31
Oracle is a scalable, reliable, flexible, and high-performance relational database management system for many server-based operating systems. Double-Take Availability provides real-time enterprise data protection and replication. Double-Take Availability can be used to provide high availability for Oracle. Double-Take Availability offers two techniques to protect Oracle database servers. Application Level protection - where database and log files are replicated to a secondary Oracle server. Full Server Protection - where the entire configuration, system state, application, data and registry are replicated to a target server that assumes the identity and function of the source server on failover. This video demonstrates the much simpler Full Server Protection option using Double-Take Availability Full Server Failover. A side feature of this video is the fact that a migration between dissimilar hardware was performed. The source Oracle server was a Hyper-V virtual machine and the target was a VMware virtual machine.

Grouping function in SQL Server
 
12:49
sql server rollup grouping sql server rollup replace null sql server rollup grouping replace null In this video we will discuss the use of Grouping function in SQL Server. This is continuation to Part 104. Please watch Part 104 from SQL Server tutorial before proceeding. What is Grouping function Grouping(Column) indicates whether the column in a GROUP BY list is aggregated or not. Grouping returns 1 for aggregated or 0 for not aggregated in the result set. The following query returns 1 for aggregated or 0 for not aggregated in the result set SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING(Continent) AS GP_Continent, GROUPING(Country) AS GP_Country, GROUPING(City) AS GP_City FROM Sales GROUP BY ROLLUP(Continent, Country, City) What is the use of Grouping function in real world When a column is aggregated in the result set, the column will have a NULL value. If you want to replace NULL with All then this GROUPING function is very handy. SELECT CASE WHEN GROUPING(Continent) = 1 THEN 'All' ELSE ISNULL(Continent, 'Unknown') END AS Continent, CASE WHEN GROUPING(Country) = 1 THEN 'All' ELSE ISNULL(Country, 'Unknown') END AS Country, CASE WHEN GROUPING(City) = 1 THEN 'All' ELSE ISNULL(City, 'Unknown') END AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Can't I use ISNULL function instead as shown below SELECT ISNULL(Continent, 'All') AS Continent, ISNULL(Country, 'All') AS Country, ISNULL(City, 'All') AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Well, you can, but only if your data does not contain NULL values. Let me explain what I mean. At the moment the raw data in our Sales has no NULL values. Let's introduce a NULL value in the City column of the row where Id = 1 Update Sales Set City = NULL where Id = 1 Now execute the following query with ISNULL function SELECT ISNULL(Continent, 'All') AS Continent, ISNULL(Country, 'All') AS Country, ISNULL(City, 'All') AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Notice that the actuall NULL value in the raw data is also replaced with the word 'All', which is incorrect. Hence the need for Grouping function. Please note : Grouping function can be used with Rollup, Cube and Grouping Sets Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/grouping-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/grouping-function-in-sql-server_25.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

This means we no longer have to use multiple statements for performing Insert, Update and Delete. With merge statement we require 2 tables 1. Source Table - Contains the changes that needs to be applied to the target table 2. Target Table - The table that require changes (Inserts, Updates and Deletes) The merge statement joins the target table to the source table by using a common column in both the tables. Based on how the rows match up as a result of the join, we can then perform insert, update, and delete on the target table. Merge statement syntax MERGE [TARGET] AS T USING [SOURCE] AS S ON [JOIN_CONDITIONS] WHEN MATCHED THEN [UPDATE STATEMENT] WHEN NOT MATCHED BY TARGET THEN [INSERT STATEMENT] WHEN NOT MATCHED BY SOURCE THEN [DELETE STATEMENT] Example 1 : In the example below, INSERT, UPDATE and DELETE are all performed in one statement 1. When matching rows are found, StudentTarget table is UPDATED (i.e WHEN MATCHED) 2. When the rows are present in StudentSource table but not in StudentTarget table those rows are INSERTED into StudentTarget table (i.e WHEN NOT MATCHED BY TARGET) 3. When the rows are present in StudentTarget table but not in StudentSource table those rows are DELETED from StudentTarget table (i.e WHEN NOT MATCHED BY SOURCE) Create table StudentSource ( ID int primary key, Name nvarchar(20) ) GO Insert into StudentSource values (1, 'Mike') Insert into StudentSource values (2, 'Sara') GO Create table StudentTarget ( ID int primary key, Name nvarchar(20) ) GO Insert into StudentTarget values (1, 'Mike M') Insert into StudentTarget values (3, 'John') GO MERGE INTO StudentTarget AS T USING StudentSource AS S ON T.ID = S.ID WHEN MATCHED THEN UPDATE SET T.NAME = S.NAME WHEN NOT MATCHED BY TARGET THEN INSERT (ID, NAME) VALUES(S.ID, S.NAME) WHEN NOT MATCHED BY SOURCE THEN DELETE; Please Note : Merge statement should end with a semicolon, otherwise you would get an error stating - A MERGE statement must be terminated by a semi-colon (;) In real time we mostly perform INSERTS and UPDATES. The rows that are present in target table but not in source table are usually not deleted from the target table. Example 2 : In the example below, only INSERT and UPDATE is performed. We are not deleting the rows that are present in the target table but not in the source table. Truncate table StudentSource Truncate table StudentTarget GO Insert into StudentSource values (1, 'Mike') Insert into StudentSource values (2, 'Sara') GO Insert into StudentTarget values (1, 'Mike M') Insert into StudentTarget values (3, 'John') GO MERGE INTO StudentTarget AS T USING StudentSource AS S ON T.ID = S.ID WHEN MATCHED THEN UPDATE SET T.NAME = S.NAME WHEN NOT MATCHED BY TARGET THEN INSERT (ID, NAME) VALUES(S.ID, S.NAME);
