我有一张桌子:
Employee (employeeID)
EmployeeRank (rankID, employeeID)
现在我有另一张桌子,其中包括所有员工将要加薪。
DueForRaise (rankID, employeeID)
我必须将DUeForRaise中的所有员工插入到EmployeeRank表中,只要他们不在同一级别。
我正在为粒子rankID @rankID做这个更新。
这会有用吗?
INSERT EmployeeRank ( rankID, employeeID)
SELECT rankID, employeeID
FROM DueForRaise dfr
OUTER JOIN EmployeeRank er er.employeeid = dfr.employeeid)
WHERE dfr.rankID = @rankID
答案 0 :(得分:13)
怎么样:
insert into EmployeeRank
select * from DueForRaise p
where NOT EXISTS(
SELECT * FROM EmployeeRank WHERE rankID=p.rankID and employeeID=p.employeeID
);
答案 1 :(得分:-1)
IF NOT EXISTS(SELECT * FROM EmployeeRank WHERE rankID = @rankID AND employeeID = @employeeID)
INSERT INTO EmployeeRank(rankID,employeeID)VALUES(@rankID,@ employeeID)
