How To Delete Multiple Rows from a Table in Oracle?
Answer:
You can delete multiple rows from a table in the same way as deleting a single row, except that the WHERE clause will match multiple rows. The tutorial exercise below deletes 3 rows from the ggl_links table:
SELECT * FROM ggl_links WHERE id >= 250;
<pre> ID URL NOTES COUNTS CREATED
----- --------------------- ----------- ------- ---------
1250 Retail Sales.com Wrong URL 500 07-MAY-06
1260 Recruiting.com Wrong URL 520 07-MAY-06
1270 Payroll.com Wrong URL 540 07-MAY-06</pre>
DELETE FROM ggl_links WHERE id >= 250;
3 row deleted.
SELECT * FROM ggl_links WHERE id >= 250;
