在一个表中使用触发器并更新另一表
CREATE TRIGGER dbo.updateTrigger
ON dbo.Education
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
IF NOT (UPDATE( HighestDegreeDoc) OR UPDATE (GPA) OR UPDATE (CreditHours))
RETURN
UPDATE dbo.School
set Uploaded =1
from dbo.School
JOIN inerted i ON i.Uploaded = School.Uploaded
END
GO
这段代码有什么问题。我正在尝试更新学校表中的字段，以及教育表中更新（HighestDegreeDoc、GPA、CrediHours）时上传的字段。注意教育表有超过15个字段，（学校表中上传的字段仅当这3个字段更改时更新）
CREATE TRIGGER dbo.updateTrigger
ON dbo.Education
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
IF NOT (UPDATE( HighestDegreeDoc) OR UPDATE (GPA) OR UPDATE (CreditHours))
RETURN
UPDATE dbo.School
set Uploaded =1
from dbo.School
JOIN inerted i ON i.Uploaded = School.Uploaded
END
GO
What is Wrong with this code. i am trying to update field in School table , field uploaded when (HighestDegreeDoc , GPA, CrediHours) update in Education Table. NOTE Education Table has more than 15 field, (Uploaded Field in School table update only when these 3 field change)

只是一个猜测...
JOIN inerted i ON i.Uploaded = School.Uploaded
应该是...
看起来更新是您正在设置的某种标志。您可能想加入 ID 列。
Just a guess....
JOIN inerted i ON i.Uploaded = School.Uploaded
Should be...
Looks like Updated is some sort of flag that you are setting. You probably want to join on an ID column instead.
这只是一个拼写错误：它是
join insert；）而且我认为您的连接条件不好。
你能给我们 ddl 吗？
It's only a typo error : it's
join inserted;)And I don't think your join condition is good.
Can you give us the ddl ?
