我正在尝试在存储过程中创建一个触发器，因为当删除表时它将被删除。

我收到错误并且无法执行它。

CREATE PROCEDURE EC5Trigger2
AS
  CREATE TRIGGER trVendorProductsPST
  ON VendorProducts
  FOR INSERT
  AS
  BEGIN
    SET NOCOUNT ON

    DECLARE  @SKU VARCHAR(64)
    SELECT @SKU = I.SKU FROM inserted AS I

    INSERT INTO ProductStockTransactions (SKU, stockingCode)
    VALUES (@SKU, 'A')
  END

  RETURN 0

联合会给正确的结果，联合会给错误的结果。

SELECT * 
  FROM (SELECT TOP 20 * 
          FROM noble_win 
         WHERE [YEAR ] = 1970 
           AND [SUBJECT   ]  NOT IN ('Economics', 'Chemistry') 
        ORDER BY [SUBJECT   ],[WINNER                ]) AS A
UNION
SELECT * 
  FROM (SELECT TOP 20 * 
          FROM noble_win 
         WHERE [YEAR ]=1970 
           AND [SUBJECT   ] IN ('Economics', 'Chemistry') 
        ORDER BY [SUBJECT   ],[WINNER                ]) AS B

此查询给出了行Chemistry和Economics比其他，然后再行Economics和Chemistry。不过，我想比其他行Economics和Chemistry第一。我不知道为什么会给出错误的结果。
