Question

我想比较Actual table和@TableType_TVP IF Duplicate Row Exist

Create procedure sp_InsertintoTable
@TableType_TVP TableType_TVP READONLY
AS

 IF(Duplicate Row not Exist then)
 Begin 
     INSERT INTO ActualTable
     Select * from @TableType_TVP

      Select Inserted row count also 
 END
else 
  Begin 
        Count Duplicate Row
  End

试试这个。注意：我没有在SSMS中测试以下查询。所以plz指出是否存在语法错误。

CREATE PROCEDURE proc_InsertintoTable 
@TableType_TVP TABLE READONLY
AS
BEGIN
    DECLARE @insertedCnt INT, @dupCnt INT

    -- FETCH DUPLICATE ROW
    SELECT @dupCnt = COUNT(*)
    FROM ActualTable atbl
    WHERE EXISTS (
            SELECT 1
            FROM @TableType_TVP tv
            WHERE atbl.ID = tv.ID
            )

    -- INSERT NEW ROW
    INSERT INTO ActualTable
        SELECT * FROM @TableType_TVP tv
        WHERE NOT EXISTS (
                SELECT 1
                FROM ActualTable atbl
                WHERE atbl.ID = tv.ID
                )

        SELECT @insertedCnt = @@Rowcount

    -- SELECT BOTH VARIABLE
    SELECT @insertedCnt, @dupCnt
    -- OR YOU CAN ALSO SET THIS 2 VARIABLE AS OUT VARIABLE

END

比较实际表与@TypeTable_TVP IF重复行存在
