问题描述
我正在尝试将一个表(t1)的记录复制到其他表(t2)。两者都有相同的字段,但我必须在复制到t2时排除某些记录。
这里是我的查询但它不起作用,当我搜索时我仍然能够看到记录
查询 -
INSERT INTO t2
SELECT * FROM t1
不存在(从t1中选择*(t1.Bus_name喜欢'009%'; t1.Bus_name喜欢'01%';));
我仍然在新表t2中看到商家名称以009和01开头的记录。
请帮助!!
Hi,
I am trying to copy records of one table(t1) to other table(t2). Both have same fields but I have to exclude certain records while copying to t2.
here is my query but it is not working and when i do search I am still able to see the records
Query -
INSERT INTO t2
SELECT * FROM t1
where not exists (select * from t1 where (t1.Bus_name like '009%'; and t1.Bus_name like '01%'; ));
I still see records with business name starting with 009 and 01 in my new table t2.
