我正在尝试编写一个在update语句中执行内部联接的查询。
以下是我正在使用的当前查询:
UPDATE
singulation1.`q096_cq33r08-ds01-n-testtable`
SET
visual = t2.visual,
inspection_status = t2.inspection_status,
inspector_name = t2.inspector_name
FROM
singulation1.`q096_cq33r08-ds01-n-testtable` t1
INNER JOIN
singulation1.`q014_bq31t05-dw30-x` t2
ON
(t1.print = t2.print AND t1.id3 = t2.id3);
关于MySql的一些东西不喜欢FROM子句。
答案 0 :(得分:2)
对于更新,您可以在update子句中指定连接
UPDATE
singulation1.`q096_cq33r08-ds01-n-testtable` AS t1
INNER JOIN singulation1.`q014_bq31t05-dw30-x` AS t2
ON t1.print = t2.print AND t1.id3 = t2.id3
SET
t1.visual = t2.visual
t1.inspection_status = t2.inspection_status,
t1.inspector_name = t2.inspector_name
