How can temporary tables be created in PL/SQL?

In PL/SQL, you can use the CREATE GLOBAL TEMPORARY TABLE statement to create a temporary table. The temporary table is automatically dropped at the end of the session.

Here is an example code for creating a temporary table:

CREATE GLOBAL TEMPORARY TABLE temp_table (
 column1 datatype1,
 column2 datatype2,
 ...
);

temp_table is the name of the temporary table, column1, column2, etc. are the column names of the table, and datatype1, datatype2, etc. are the data types of the columns.

After creating a temporary table, you can insert, query, update, and delete from it just like you would with a regular table.

Please note that the definition of temporary tables is only visible within the current session and cannot be accessed directly by other sessions.
