存储过程存在详细信息未验证

Question

我创建了存储过程，我想检查UserCategoryCode和UserCategoryName，现有记录，我是existing record，但是没有为UserCategoryCode,正确使用它我该怎么做？我试着这样做，但没有工作，（它的工作是UserCategoryName）

SP

ALTER PROCEDURE [dbo].[UserCategories_InsertUpdate]
@UserCategoryId int,
@UserCategoryCode   varchar(50),
@UserCategoryName varchar(250),
@Remarks nvarchar(max),
@StatusId int,
-- @StatusChangeDate DATETIME,
@CreateId int,
@Mode varchar(50),
@iOutput int output

AS
BEGIN

    BEGIN TRY
    BEGIN TRAN


    IF @Mode = 'Add'
    BEGIN
    IF NOT EXISTS (SELECT UserCategoryCode,UserCategoryName FROM UserCategories WHERE  UserCategoryCode = @UserCategoryCode AND UserCategoryName = @UserCategoryName) 
        BEGIN

            INSERT INTO  UserCategories(

                 UserCategoryCode,
                 UserCategoryName, 
                 StatusId,
                 StatusChangeDate,
                 CreateBy,
                 CreatedDate,
                 Remarks 

                 )
                 VALUES(
                 @UserCategoryCode,
                 @UserCategoryName,
                 @StatusId,GETDATE(),
                 @CreateId,GETDATE(),
                 @Remarks


                 )



        SET @iOutput = 1 --save successful--
        END

        ELSE

        BEGIN
            SET @iOutput=-3 --existing record--
        END
    END
    ELSE IF @Mode = 'Modify'
    BEGIN

                        UPDATE  UserCategories

                        SET UserCategoryCode   =   @UserCategoryCode,
                            UserCategoryName  = @UserCategoryName,
                            StatusId = @StatusId,
                            Remarks  = @Remarks,
                            EditBy   = @CreateId, 
                            EditDate =  GETDATE()


                        WHERE  UserCategoryId = @UserCategoryId

                        SET @iOutput = 2    --save successful-- 

    END 

    COMMIT 

    END TRY

    BEGIN CATCH
        print ERROR_MESSAGE()
        SET @iOutput = -2   --sp error--
        ROLLBACK        
    END CATCH

哦，最后它的工作，我找到了解决方案，

IF NOT EXISTS (SELECT UserCategoryCode FROM UserCategories WHERE UserCategoryCode = @UserCategoryCode)     IF NOT EXISTS (SELECT UserCategoryName FROM UserCategories WHERE UserCategoryName = @UserCategoryName)

BEGIN

            INSERT INTO  UserCategories(

                 UserCategoryCode,
                 UserCategoryName, 
                 StatusId,
                 StatusChangeDate,
                 CreateBy,
                 CreatedDate,
                 Remarks 

                 )
                 VALUES(
                 @UserCategoryCode,
                 @UserCategoryName,
                 @StatusId,GETDATE(),
                 @CreateId,GETDATE(),
                 @Remarks


                 )



        SET @iOutput = 1 --save successful--
        END

        ELSE

        BEGIN
            SET @iOutput=-3 --existing record--
        END
        ELSE

        BEGIN
            SET @iOutput=-5 --existing record--
        END

    END
    ELSE IF @Mode = 'Modify'
    BEGIN

                        UPDATE  UserCategories

                        SET UserCategoryCode   =   @UserCategoryCode,
                            UserCategoryName  = @UserCategoryName,
                            StatusId = @StatusId,
                            Remarks  = @Remarks,
                            EditBy   = @CreateId, 
                            EditDate =  GETDATE()


                        WHERE  UserCategoryId = @UserCategoryId

                        SET @iOutput = 2    --save successful-- 

    END 

    COMMIT 

    END TRY

    BEGIN CATCH
        print ERROR_MESSAGE()
        SET @iOutput = -2   --sp error--
        ROLLBACK        
    END CATCH

END

和代码

 else if (output == -3)
                {
                    lblMsg.Text = "Already Exists!";
                    lblMsg.ForeColor = System.Drawing.Color.Orange;
                }

                else if (output == -5)
                {
                    lblMsg.Text = "Already Exists!";
                    lblMsg.ForeColor = System.Drawing.Color.Orange;
                }
