What is Autonomous transaction in Oracle. This is very frequently asking question in Interview. Hello Friend, in this Video You can learn how we can give the answer of Autonomous Transactions. An autonomous transaction is available from Oracle 8i. It is a very cool, useful, unique and powerful feature in oracle. An autonomous transaction is an independent transaction that is initiated by another transaction. It must contain at least one Structured Query Language (SQL) statement. When an autonomous transaction is called, the original transaction (calling transaction) is temporarily suspended. The autonomous transaction must commit or roll back before it returns control to the calling transaction. Once changes have been made by an autonomous transaction, those changes are visible to other transactions in the database. Autonomous transactions can be nested. For use Autonomous Transactions feature in program we have to use PRAGMA AUTONOMOUS_TRANSACTION Key word in Program When to use Autonomous Transactions? • Logging mechanism you need to log an error to your database log table. On the other hand, you need to roll back your core transaction because of the error. And you don't want to roll back over other log entries. • Commits and rollbacks in your database triggers If you define a trigger as an autonomous transaction, then you can commit and/or roll back in that code. • Software usage meter You want to keep track of how often a program is called during an application session. This information is not dependent on, and cannot affect, the transaction being processed in the application. Mutation Error Using autonomous transaction we can avoid mutation error.

Oracle tutorial : Autonomous Transactions in Oracle 11g PL SQL-PRAGMA What is pragma autonomous_transaction An autonomous transaction is an independent transaction to the main or parent transaction. If an Autonomous transaction is started by another transaction it is not nested, but independent of parent transaction. PRAGMA autonomous_transaction 1)In Oracle session, all of the changes made to data are part of a single transaction. 2)An autonomous transaction is an independent transaction started within another transaction (the main transaction). 3)Autonomous transactions allow you to temporarily suspend the main transaction, perform additional SQL operations, commit or rollback those operations separately, then resume the main transaction. 4)To define an autonomous transaction, we can use a PRAGMA statement PRAGMA AUTONOMOUS_TRANSACTION; CREATE TABLE log_data ( empno NUMBER(6), userid VARCHAR2(30), create_date DATE ); CREATE OR REPLACE TRIGGER add_log BEFORE INSERT OR UPDATE ON employee FOR EACH ROW DECLARE PRAGMA AUTONOMOUS_TRANSACTION; — This statement made this autonomous this trigger BEGIN INSERT INTO log_data VALUES (:new.id, USER, SYSDATE); COMMIT; END; / Insert into EMPLOYEE (ID, NAME, CITY, SALARY, DEPT_NO) Values (20, ‘MY Tech Query’, ‘Mumbai’, 20000, 1) ROLLBACK; SELECT * FROM EMPLOYEE SELECT * FROM LOG_DATA https://www.youtube.com/channel/UCpiyAesWNYOXSz5GPq8lbkA For more tutorial please visit #techquerypond https://techquerypond.com https://techquerypond.wordpress.com https://twitter.com/techquerypond oracle transaction pragma autonomous_transaction

PL/SQL: Mutating Triggers Part-1
 
06:24
In this tutorial, you'll learn... 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.

Learn in depth with example about creating user defined exception using Pragma Exception_INIT and Raise_application_error following handling of different types of system named and unnamed exception in details. How to handle exception in oracle database, How to handle user defined exception in oracle database, What is Pragma in Exception Handling, What is Pragma Exception_INIT in oracle, Types of exception available in oracle, How to use Raise_application_error in oracle, How to use custom exception in oracle, How to use pragma autonomous transaction, SQLERRM, SQLCODE, Raise_application_error, In Oracle PL/SQL, PRAGMA refers to a compiler directive or "hint" it is used to provide an instruction to the compiler. The 5 types of Pragma directives available in Oracle are listed below: * PRAGMA AUTONOMOUS_TRANSACTION * PRAGMA SERIALLY_REUSABLE * PRAGMA RESTRICT_REFRENCES * PRAGMA EXCEPTION_INIT * PRAGMA INLINE Details of System Exception: DUP_VAL_ON_INDEX ORA-00001 You tried to execute an INSERT or UPDATE statement that has created a duplicate value in a field restricted by a unique index. TIMEOUT_ON_RESOURCE ORA-00051 You were waiting for a resource and you timed out. TRANSACTION_BACKED_OUT ORA-00061 The remote portion of a transaction has rolled back. INVALID_CURSOR ORA-01001 You tried to reference a cursor that does not yet exist. This may have happened because you've executed a FETCH cursor or CLOSE cursor before OPENing the cursor. NOT_LOGGED_ON ORA-01012 You tried to execute a call to Oracle before logging in. LOGIN_DENIED ORA-01017 You tried to log into Oracle with an invalid username/password combination. NO_DATA_FOUND ORA-01403 You tried one of the following: You executed a SELECT INTO statement and no rows were returned. You referenced an uninitialized row in a table. You read past the end of file with the UTL_FILE package. TOO_MANY_ROWS ORA-01422 You tried to execute a SELECT INTO statement and more than one row was returned. ZERO_DIVIDE ORA-01476 You tried to divide a number by zero. INVALID_NUMBER ORA-01722 You tried to execute a SQL statement that tried to convert a string to a number, but it was unsuccessful. STORAGE_ERROR ORA-06500 You ran out of memory or memory was corrupted. PROGRAM_ERROR ORA-06501 This is a generic "Contact Oracle support" message because an internal problem was encountered. VALUE_ERROR ORA-06502 You tried to perform an operation and there was a error on a conversion, truncation, or invalid constraining of numeric or character data. CURSOR_ALREADY_OPEN ORA-06511 You tried to open a cursor that is already open.

What is Parameterized Cursor in Oracle
 
03:39
What is Parameterized Cursor in Oracle. In simple words a cursor with parameter is called parameterized cursor. PL/SQL allows developer to pass parameters into cursors. Same as like we can pass parameter into function and procedure. PL/SQL Parameterized cursor pass the parameters into a cursor and use them in to query. Cursor becomes more reusable using Cursor parameters. PL/SQL Parameterized cursor define only data type of parameter and not need to define it's length. In Parameterized cursor scope of the parameters are local within program only. Optionally, we can also give a default value for the parameter, which will take effect if no value is passed to the cursor. Key point 1. Scope of the parameters are locally 2. You can assign default value to a cursor parameter. 3. Cursor becomes more reusable with Cursor parameters. 4.PL/SQL Parameterized cursor define only data type of parameter and not need to define it's length.
