有两个字段唯一确定表里是否有那些记录，如果没有就插入这些记录，要怎样做？？？

[littlecainiao]

如果在表UserManage里的字段User_ManageDeptID，cUser_id有记录
而表Yearbudget的字段ideptmentID,Ideptmanage没有相关记录，就插入一些记录。
好象not in 只能表示一个字段。不知应该怎改下面的语句：

insert Yearbudget (iitemid,ideptmentID,Ideptmanage)
select B.Iitemid ,U.User_ManageDeptID,U.cUser_id from BudgetItem B
,UserManage U
where ((U.User_ManageDeptID ,U.cUser_id) not in (select distinct ideptmentID,Ideptmanage from YearBudget )

两个not in 用AND连接起来，也是不行的

insert Yearbudget (iitemid,ideptmentID,Ideptmanage)
select B.Iitemid ,U.User_ManageDeptID,U.cUser_id from BudgetItem B
,UserManage U
where not exists (select 1 from YearBudget where ideptmentID=U.User_ManageDeptID and Ideptmanage=U.cUser_id)

你的u和b没有关联?

insert Yearbudget (iitemid,ideptmentID,Ideptmanage)
select B.Iitemid ,U.User_ManageDeptID,U.cUser_id from BudgetItem B
,UserManage U
where b.关联列=U.关联列 and not exists (select 1 from YearBudget where ideptmentID=U.User_ManageDeptID and Ideptmanage=U.cUser_id)

try:
insert Yearbudget (iitemid,ideptmentID,Ideptmanage)
select B.Iitemid ,U.User_ManageDeptID,U.cUser_id from BudgetItem B
,UserManage U
where not exists(select 1 from YearBudget where ideptmentid = u.user_manageDeptID and Ideptmanage = U.cUser_id)

insert into Yearbudget (...)
select (...)
from usermanage a left join yearbudget b
on a.user_managedeptid=b.ideptmentid and a.cuser_id =b.ideptmanage
where b.ideptmentid is null
