Question

目前我正在尝试在SQL Server中创建存储过程。

这是我的存储过程：

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

但是，在执行脚本的那一刻，我收到了这个错误：

Msg 156，Level 15，State 1，Server e8535208dabe，Procedure sp_MasterManagement，Line 24
  关键字“IF”附近的语法不正确。

Msg 156，Level 15，State 1，Server e8535208dabe，Procedure sp_MasterManagement，Line 27
  关键字“IF”附近的语法不正确。

Msg 156，Level 15，State 1，Server e8535208dabe，Procedure sp_MasterManagement，Line 30
  关键字“END”附近的语法不正确。

我不知道，我不明白为什么我会收到此错误。到目前为止，我相信我的语法很好。有什么想法吗？

你走了：

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

由于语法格式错误，if子句无法创建存储过程？
