我有两张桌子,
这是我的第一张桌子,
ID SUBST_ID CREATED_ID
1 031938 TEST123
2 930111 COOL123
3 000391 THIS109
4 039301 BRO1011
5 123456 COOL938
... ... ...
这是我的第二张桌子,
ID SERIAL_ID BRANCH_ID
1 039301 NULL
2 000391 NULL
3 123456 NULL
... ... ...
我需要了解如何使用第一个表中的数据更新第二个表中的所有行.
I need to some how update all rows within my second table using data from my first table.
它需要在一个更新查询中完成这一切.
It would need to do this all in one update query.
SUBST_ID 和 SERIAL_ID 都匹配,需要从第一个表中获取 created_id 插入到第二个表中.
Both SUBST_ID and SERIAL_ID match, it needs to grab the created_id from the first table and insert it into the second table.
所以第二个表会变成下面这样,
So the second table would become the following,
ID SERIAL_ID BRANCH_ID
1 039301 BRO1011
2 000391 THIS109
3 123456 COOL938
... ... ...
感谢您的帮助和指导.
UPDATE TABLE2
JOIN TABLE1
ON TABLE2.SERIAL_ID = TABLE1.SUBST_ID
SET TABLE2.BRANCH_ID = TABLE1.CREATED_ID;
