Question

我有一个奇怪的问题，我的游戏有一个触发器。

我收到以下错误，但看不到问题所在。

“ 2019-03-13 14:30:01 err = -1，[Microsoft] [ODBC SQL Server驱动程序] [SQL Server] 子查询返回了多个值。 {{1} }，当子查询遵循=，！=，<，<=，>，> =或将子查询用作表达式时。SQL状态：21000，本地错误：512（0x200）

2019-03-13 14:30:01 :: SaveCharacter 1144 Lexii ret = 1，qerr = -1，{？=致电Usp_Save_Char_Quest_Add_E（1144,2222,0,0,0,0）}“

This is not permitted

Answer 1

试试看！希望这能解决您的问题。

DECLARE @QuestID INT = (SELECT QuestID FROM inserted)

        IF @QuestID = 2222 -- The Perfect Orange Stats QuestID
        BEGIN

            DECLARE @CharID INT = (SELECT CharID FROM inserted)
            DECLARE @UserUID INT = (SELECT TOP 1 UserUID FROM Chars WHERE CharID = @CharID)

这个问题只发生在某些玩家身上，似乎这个存储过程是错误的

USE [PS_GameData]
GO
/****** Object:  StoredProcedure [dbo].[usp_Save_Char_Quest_Add_E]    Script Date: 13/03/2019 18:02:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


ALTER Proc [dbo].[usp_Save_Char_Quest_Add_E]

@CharID int,
@QuestID int,
@Delay smallint = Null,
@Count1 tinyint = Null,
@Count2 tinyint = Null,
@Count3 tinyint = Null

AS

SET NOCOUNT ON

INSERT INTO CharQuests(CharID,QuestID,[Delay],Count1,Count2,Count3) VALUES(@CharID,@QuestID,@Delay,@Count1,@Count2,@Count3)

IF(@@ERROR = 0)
BEGIN
    RETURN 1
END
ELSE
BEGIN
    RETURN -1
END

SET NOCOUNT OFF

[Microsoft] [ODBC SQL Server驱动程序] [SQL Server]子查询返回了多个值
