What tables are used in oracle stored procedures?

Tables used in Oracle stored procedures

In Oracle stored procedures, you can access and modify the tables in the database table to implement complex data operations. The tables used by stored procedures can be divided into two main types:

Input/Output Tables

These tables are used to transfer data during the execution of the stored procedure.

  • Input tables: Stored procedures read data from these tables and use them as input.
  • Output tables: Stored procedures write results to these tables for external use.

Temporary tables

These tables are used only during the execution of a stored procedure and are usually used to store temporary data or intermediate results. Use the CREATE GLOBAL TEMPORARY TABLE statement when creating a temporary table.

The following are some examples of using tables in Oracle stored procedures:

  • Insert data: Use the INSERT INTO statement to insert data Output table.
  • Update data: Use the UPDATE statement to update data in the input table or temporary table.
  • Delete data: Use the DELETE statement to delete data from an input table or temporary table.
  • Retrieve data: Use the SELECT statement to retrieve data from an input table or temporary table.

When using a table in a stored procedure, you need to consider the following:

  • Make sure that the stored procedure has the appropriate permissions on the table.
  • Avoid abusing temporary tables in stored procedures as they can take up a lot of space.
  • Clearly define the expected behavior of tables used by stored procedures.
