How To Update Values on Multiple Rows? - Oracle DBA FAQ - Understanding SQL DML Statements
✍: FYIcenter.com
If the WHERE clause in an UPDATE matches multiple rows, the SET clause will be applied to all matched rows. This rule allows you to update values on multiple rows in a single UPDATE statement. Here is a good example:
UPDATE fyi_links SET counts = 9, notes = 'Wrong URL' WHERE id >= 250; 3 rows updated. SELECT * FROM fyi_links WHERE id >= 250; ID URL NOTES COUNTS CREATED ----- -------------------- ------------ ------- --------- 250 Retail Sales.com Wrong URL 9 07-MAY-06 260 Recruiting.com Wrong URL 9 07-MAY-06 270 Payroll.com Wrong URL 9 07-MAY-06
This statement updated 3 rows with the same new values on all 3 rows.
