Question

这里我尝试使用存储过程添加批量数据但问题是我不想更新数据我想在条件匹配时将数据插入临时表

 Alter PROCEDURE [dbo].[Update_Customers] 
     @typeMembership aspnet_Membership_type READONLY
    AS
    BEGIN
          SET NOCOUNT ON;

          MERGE INTO aspnet_Membership c1
          USING @typeMembership c2
          ON c1.EmployeeCode=c2.EmployeeCode
          WHEN MATCHED THEN
          UPDATE SET  
          c1.[EmployeeCode] =  c2.[EmployeeCode] ,
          c1.[EmployeeTypeId] = c2.[EmployeeTypeId] ,
          c1.[FirstName] = c2.[FirstName] ,
          c1.[LastName] =  c2.[LastName] ,
          c1.[Gender] =  c2.[Gender] ,
          c1.[Email] =  c2.[Email]  ,
          c1.[MobilePIN] = c2.[MobilePIN] ,
          c1.[Current_Address] =  c2.[Current_Address] ,
          c1.[Permanent_Address] =  c2.[Permanent_Address] ,
          c1.[IsApproved] = c2.[IsApproved]  
          WHEN NOT MATCHED THEN
          INSERT VALUES (c2.EmployeeCode, c2.EmployeeTypeId,c2.FirstName,c2.LastName,c2.Gender,c2.Email,c2.MobilePIN,c2.Current_Address, c2.Permanent_Address,c2.IsApproved);
    END

AFAIK你无法通过合并来做到这一点。您必须编写不同的插入语句：

BEGIN TRY
BEGIN TRANSACTION

INSERT INTO thirdTable (<ColumnsList>)
SELECT <ValuesList>
FROM @typeMembership c2
WHERE EXISTS
(
    SELECT 1
    FROM aspnet_Membership c1
    WHERE c1.EmployeeCode = c2.EmployeeCode
);

INSERT INTO aspnet_Membership (<ColumnsList>)
SELECT <ValuesList>
FROM @typeMembership c2
WHERE NOT EXISTS
(
    SELECT 1
    FROM aspnet_Membership c1
    WHERE c1.EmployeeCode = c2.EmployeeCode
);

COMMIT TRANSACTION
END TRY
BEGIN CATCH
    IF @@Trancount > 0
        ROLLBACK TRANSACTION
END CATCH

如何使用合并查询在不同的表中插入
