Question

我有下面的触发器写入，它对单列更新（firstname）完全正常，但是我们现在需要更新一些额外的列（lastname，mobileNumber等）

CREATE TRIGGER apl.updateJaWithCandidateDataAfterInsert ON [APL].[tblJobApplications_v2]
AFTER INSERT
AS
SET NOCOUNT ON

UPDATE [APL].[tblJobApplications_v2]
SET FirstName = (
        SELECT FirstName
        FROM [USR].[tblUserDetails]
        WHERE inserted.CandidateId = [USR].[tblUserDetails].CandidateId
        )
FROM [APL].[tblJobApplications_v2]
INNER JOIN Inserted ON [APL].[tblJobApplications_v2].CandidateId = Inserted.CandidateId
GO

尝试了一些选择，但无法使这些工作。有人可以指出我正确的方向吗？

Answer 1

[USR].[tblUserDetails]

可能还需要一个内连接

UPDATE [APL].[tblJobApplications_v2]
SET FirstName = [USR].[tblUserDetails].FirstName,
    LastName  = [USR].[tblUserDetails].LastName
FROM [APL].[tblJobApplications_v2]
INNER JOIN Inserted ON [APL].[tblJobApplications_v2].CandidateId = Inserted.CandidateId
INNER JOIN [USR].[tblUserDetails] ON inserted.CandidateId = [USR].[tblUserDetails].CandidateId

使用set更新/设置多个列并选择语句
