What is temporary table in SQL in English and Hindi
Temporary table in SQL in Engilsh
In SQL, a temporary table is a table that is created and exists only for the duration of a database session. Temporary tables are used to store data temporarily, which can be used in subsequent queries or stored procedures. Once the database session ends, the temporary table is automatically deleted.
Temporary tables can be created in two ways: local and global. Local temporary tables are visible only to the session that creates them, and they are automatically dropped when the session ends. Global temporary tables are visible to all sessions and are dropped when the last session referencing them ends.

Once the temporary table is created, data can be inserted, updated, or deleted using standard SQL statements. After the database session ends, the temporary table is automatically deleted.
