在sql命令行,刪除一條記錄時(shí),發(fā)現(xiàn)一個(gè)很奇怪的錯(cuò)誤

下面的語句是可以正常執(zhí)行的:

delete from t_mid_test_convention where convention_id=33;

但是下面的報(bào)語法錯(cuò):

delete from t_mid_test_convention as mt2 where mt2.convention_id=33;

mysql>

mysql> delete from t_mid_test_convention as mt2 where mt2.convention_id=33;

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'as mt2 where mt2.convention_id=33' at line 1

mysql> delete from t_mid_test_convention as mt2 where mt2.convention_id=33;

mysql> delete from t_mid_test_convention where convention_id=33;

Query OK, 0 rows affected (0.20 sec)
