Oracle SQL MERGE Statement
 
07:52
https://www.databasestar.com/oracle-merge-sql/ In this video, we’ll learn what the Oracle MERGE statement does and how you can use it. What is the MERGE statement? It’s a statement that lets you either insert or update data in a table - all in a single statement! It’s helpful if you’re using an ETL (Extract Transform Load) process when creating or updating a data warehouse. It’s also helpful when loading data into your own database if you’re not creating a data warehouse. It allows you to prevent duplicate data and ensure you have up-to-date data in your table. The syntax looks like this: MERGE INTO table_name USING table_name ON (condition) WHEN MATCHED THEN update_clause DELETE where_clause WHEN NOT MATCHED THEN insert_clause [LOG ERRORS log_errors_clause reject_limit integer | unlimited ] In this video, I also show an Oracle SQL MERGE statement example, so watch the video to find out more. For more information on the MERGE statement and how you can use it in your queries, read the related article here: https://www.databasestar.com/oracle-merge-sql/

Delete, Drop, and Truncate Statements in Hive
 
06:41
Delete, Drop, and Truncate Statements in Hive Delete Statement: Delete statement is used to delete certain rows from a table based on a condition specified using the WHERE clause. The syntax is in below as highlighted. DELETE FROM tablename [WHERE expression]; Note: DELETE statement is available from hive 0.14.0 version and above Drop Statement: The drop table statement is used to drop the table altogether. The syntax is highlighted here: DROP TABLE IF EXISTS TABLENAME; Let’s quickly see how the managed table and external table differs when dropping the table. We have already discussed this in the “Two different types of hive tables” video. Take a look at it if you haven’t. For the managed hive tables, the drop table statement removes the metadata information as well as the data. The data will be actually moved to .Trash/Current directory. metadata will be permanently deleted. However for external tables, only the metadata information is permanently deleted and the actual data remains intact in the hdfs directories. So in the case of external table, if the table was deleted accidentally, then the table can be re-created by using the same schema and specifying the same location for the hdfs data directory. If deleting the external table was the intention, then after deleting the table using the drop statement, you may also delete the underlying hdfs data directory by issuing the hdfs dfs -rm command. Truncate Statement: Truncate table statement is used to remove only the data from the table. The table structure with the schema remains intact. Truncate removes all the rows from a table or partition. The syntax is highlighted below. TRUNCATE table syntax TRUNCATE TABLE TABLENAME;
