update: 添加where条件中的值表达式审核,避免无效表达式误更新 (#178)

[hanchuanchuan]

审核以下形式的SQL(仅UPDATE和DELETE)：

update t1 set c1 = 1 where 123;
update t1 set c1 = 1 where null;
update t1 set c1 = 1 where 1+2;
update t1 set c1 = 1 where 1-2;
update t1 set c1 = 1 where 1*2;
delete from t1 where 1/2;
delete from t1 set c1 = 1 where 1&2;
delete from t1 set c1 = 1 where 1|2;
delete from t1 set c1 = 1 where 1^2;
delete from t1 set c1 = 1 where 1 div 2;

审核结果如下(隐藏了部分列)：

order_id	stage	error_level	stage_status	error_message	sql
1	CHECKED	0	Audit Completed	None	use test
2	CHECKED	1	Audit Completed	Please confirm if you want to use value expression in where condition.	update t1 set id = 1 where 123;

中文结果：

order_id	stage	error_level	stage_status	error_message	sql
1	CHECKED	0	Audit Completed	None	use test
2	CHECKED	1	Audit Completed	请确认是否要在where条件中使用值表达式.	update t1 set id = 1 where 123;
