Question

我正在尝试将触发器保存在存储过程中，因为删除表时将删除触发器。

我遇到错误，无法执行。

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

Answer 1

这是使用动态SQL在存储过程内创建触发器的方法，这是唯一的方法。

CREATE PROCEDURE EC5Trigger2
AS
BEGIN
  SET NOCOUNT ON;

  DECLARE @TriggerCode NVARCHAR(max);

  SET @TriggerCode = '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';

  EXEC(@TriggerCode);

  RETURN 0;
END
