DELETE Statement

Delete rows from a table, or view.

Syntax:

   DELETE [FROM] [schema.] table [@dblink] [alias]
      WHERE (condition)
         [RETURNING expr INTO DATA_ITEM]

   DELETE [FROM] [schema.] table [SUB]PARTITION partition [alias]
      WHERE (condition)
         [RETURNING expr INTO DATA_ITEM]

   DELETE [FROM] [schema.] view [@dblink] [alias]
      WHERE (condition)
         [RETURNING expr INTO DATA_ITEM]

   DELETE [FROM] subquery [WITH READ ONLY] [alias]
      WHERE (condition)
         [RETURNING expr INTO DATA_ITEM]

   DELETE [FROM] subquery [WITH CHECK OPTION] [CONSTRAINT constraint] [alias]
      WHERE (condition)
         [RETURNING expr INTO DATA_ITEM]

To improve performance, you may also add a hint to any of the above… DELETE hint FROM Schema.table…

Example:

The following example returns column es_salary from the deleted rows and stores the result in bind array :1

DELETE FROM t_employee_salary
WHERE es_emp_id = 1075 AND es_commission = 50 
RETURNING es_salary INTO :1;
