• To delete rows, you must own the table or have delete permission.

• Do not mix range variables with table names in a delete statement: the resulting disjoint query gives unexpected results. The following example illustrates a disjoint query; the table name following the keyword delete is not the same as the range variable specified in the where clause. All rows are deleted as a result of this disjoint query.

• After deleting a large number of rows from a table, you can use the modify statement to recover empty space. To delete all rows in a table, you can use the modify tablename to truncated. For more information, see Modify Statement--Change Table or Index Properties.
