phone FROM tb_user
WHERE ucid=271338;
+--------------+------+-------------------+
| PNumber | Ext | phone |
+--------------+------+-------------------+
| 010-88888882 | 5612 | 010-88888882-5612 |
+--------------+------+-------------------+
变更分机号码为1234:
UPDATE tb_user SET
phone=CPNCAT( SUBSTRING_INDEX( phone,'-',2 ), '-', '1234' )
WHERE ucid = 271338;
