Deleting Data
THE DELETE STATEMENT
• SQL provides for the removal of rows from database tables by use of the
DELETE statement.
• You can delete all the rows in a table by using an unqualified DELETE statement, or you can restrict the deletion to only selected rows by adding a WHERE clause.
DELETE FROM table_name WHERE condition;
EXAMPLE:
DELETE FROM CUSTOMER
WHERE FirstName = 'David' AND LastName = 'Taylor';
THE DELETE STATEMENT
• The WHERE clause specifies which record(s) should be deleted. If you omit the WHERE clause, all records in the table will be deleted.
