在sql命令行,删除一条记录时,发现一个很奇怪的错误

下面的语句是可以正常执行的:

delete from t_mid_test_convention where convention_id=33;

但是下面的报语法错:

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;
