Bug Report

1. What did you do?

mysql> set;
Query OK, 0 rows affected (0.01 sec)

2. What did you expect to see?

mysql> set;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

3. What did you see instead?

Executed without error. This is really unintuitive.

4. What version of TiDB are you using? (tidb-server -V or run select tidb_version(); on TiDB)
