잘못된 구문, if 절로 인해 저장 프로 시저를 만들 수 없습니까?

Question

현재 SQL Server에서 저장 프로 시저를 만들려고합니다.

이 내 저장 프로 시저입니다 : 스크립트를 실행하는 순간에

CREATE PROCEDURE sp_MasterManagement 
    @ProductId INT, 
    @ProductName NVARCHAR(40), 
    @SupplierID INT, 
    @CategoryID INT, 
    @QuantityPerUnit NVARCHAR(20), 
    @UnitPrice DECIMAL(10, 5), 
    @UnitsInStock SMALLINT, 
    @UnitsOnOrder SMALLINT, 
    @ReorderLevel SMALLINT, 
    @Discontinued BIT, 
    @StatementType VARCHAR 
AS 
BEGIN 
    IF @StatementType = 'INSERT' 
    BEGIN 
     INSERT INTO [dbo].Products (ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued) 
     VALUES (@ProductName, @SupplierID, @CategoryID, @QuantityPerUnit, @UnitPrice, @UnitsInStock, @UnitsOnOrder, @ReorderLevel, @Discontinued); 

     DECLARE @LastInserted INT; 
     SELECT @LastInserted = SELECT ScopeIdentity(); 

     SELECT * 
     FROM [dbo].Products 
     WHERE ProductID = @LastInserted 
    END 

    IF @StatementType = 'UPDATE' 
    BEGIN 
     UPDATE Products 
     SET ProductName = @ProductName, 
      SupplierID = @SupplierID, 
      CategoryID = @CategoryID, 
      QuantityPerUnit = @QuantityPerUnit, 
      UnitPrice = @UnitPrice, 
      UnitsInStock = @UnitsInStock, 
      UnitsOnOrder = @UnitsOnOrder, 
      ReorderLevel = @ReorderLevel, 
      Discontinued = @Discontinued 
     WHERE ProductID = @ProductID; 

     SELECT * 
     FROM Products 
     WHERE ProductID = @ProductID 
    END 
END 
GO 

그러나,이 오류가 얻을 :

Msg 156, Level 15, State 1, Server e8535208dabe, Procedure sp_MasterManagement, Line 24
Incorrect syntax near the keyword 'IF'.

Msg 156, Level 15, State 1, Server e8535208dabe, Procedure sp_MasterManagement, Line 27
Incorrect syntax near the keyword 'IF'.

Msg 156, Level 15, State 1, Server e8535208dabe, Procedure sp_MasterManagement, Line 30
Incorrect syntax near the keyword 'END'.

모르겠다을 나는 이해가 안 돼요 왜이 오류가 발생하는지. 지금까지는 구문이 잘 형성되어 있다고 생각합니다. 어떤 아이디어? 여기

당신은 갈 :

CREATE PROCEDURE sp_MasterManagement 
@ProductId INT, 
@ProductName NVARCHAR(40), 
@SupplierID INT, 
@CategoryID INT, 
@QuantityPerUnit NVARCHAR(20), 
@UnitPrice DECIMAL(10, 5), 
@UnitsInStock SMALLINT, 
@UnitsOnOrder SMALLINT, 
@ReorderLevel SMALLINT, 
@Discontinued BIT, 
@StatementType VARCHAR 
AS 
    BEGIN 
    IF @StatementType = 'INSERT' 
     BEGIN 
     INSERT INTO [dbo].Products (ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued) 
     VALUES (@ProductName, @SupplierID, @CategoryID, @QuantityPerUnit, @UnitPrice, @UnitsInStock, @UnitsOnOrder, @ReorderLevel, @Discontinued); 
     DECLARE @LastInserted INT; 
     SELECT @LastInserted = (SELECT Scope_Identity); 
     SELECT * FROM [dbo].Products WHERE ProductID = @LastInserted; 
     END 
    IF @StatementType = 'UPDATE' 
     BEGIN 
     UPDATE Products SET ProductName = @ProductName, 
          SupplierID = @SupplierID, 
          CategoryID = @CategoryID, 
          QuantityPerUnit = @QuantityPerUnit, 
          UnitPrice = @UnitPrice, 
          UnitsInStock = @UnitsInStock, 
          UnitsOnOrder = @UnitsOnOrder, 
          ReorderLevel = @ReorderLevel, 
          Discontinued = @Discontinued 
         WHERE ProductID = @ProductID; 
     SELECT * FROM Products WHERE ProductID = @ProductID; 
     END 
    END 
GO
