In this article, we have learned about MySQL temp tables, and the characteristics of it. Specify the temporary keyword otherwise, if a table with the same will be dropped To create a temporary table based on the definition of another table, you must use the following syntaxĪs I mentioned that the on a database a temporary table and an InnoDB table can have same name so make sure you You cannot create a temporary table based on the definition that the table already has, and it resides on MySQL tablespace, a general tablespace, or InnoDB tablespace. Once the procedure completes successfully, the privileges will be reverted In such cases, MySQL uses the privileges of the USER 1 to create the temporary table.

Now, USER 2 tries to execute it, but it does not have the create temporary table permission. Suppose the stored procedure that uses a temporary table and a USER 1 who had developed the procedure has the create temporary table privilege. There is one implication of this behavior. Once it is granted, then to update, delete, or insert the data within that temporary table does not require any special privileges. To create a temporary table within the stored procedure, the user must have create temporary table privilege. If you disabled the InnoDB_strict_mode parameter, MySQL will issue a warning and create a table with a non-compressed row format If you had enabled the InnoDB_strict_mode parameter, then it will return an error. The InnoDB database engine does not support the compressed, temporary table. MySQL Temporary table has a decoupled relationship with the database schema, which means that when we drop the MySQL database, it does not necessarily drop the temporary tables within the database In such cases, instead of applying the filter on the table multiple times, you can save the subset of large tables in a temporary table and use it within a stored procedure. The temporary tables are useful when you want to use a small subset of the large table, and it is being used multiple times within a stored procedure. Two different sessions can have a temporary table Session ID 502 cannot access it or manipulate it. For example, Session ID 501 has created a temporary table then A temporary table exists within a session only therefore, a table created by one session is not When the session closes, the table isĭropped by itself. Tables are session-specific tables that are created within the session.
