Create Oracle Temporary Tables: Complete Guide

The method that Oracle uses to create temporary tables is by using the keyword “GLOBAL TEMPORARY TABLE” to create the temporary table. The data in the temporary table will be automatically deleted at the end of the session. The syntax for creating a temporary table is as follows:

CREATE GLOBAL TEMPORARY TABLE temp_table_name
(
   column1 datatype,
   column2 datatype,
   ...
)
ON COMMIT DELETE ROWS;

In this syntax, “temp_table_name” refers to the name of the temporary table, and “column1, column2, …” refers to the names and data types of the columns in the table. The option “ON COMMIT DELETE ROWS” indicates that data in the table will be automatically deleted when the session is committed.
