Question

我知道围绕Stack Overflow有很多类似的问题，但没有一个能解决我的问题。

这是我存储过程中的一行：

SET @AdIDNumber = PARSENAME(REPLACE(@AdIDNumber, '-', '.'), 1);

ADIDNumber是传递给此存储过程的参数。我正在尝试将ADIDNumber nvarchar的最后一个组件分隔为'-'。我收到以下错误：

从字符串转换为uniqueidentifier时转换失败。

奇怪的是，每次都不会发生这种情况。以下是一些有效的ADIDNumbers：

188CR-000O-000199
188CR-000D-000105

和一些导致错误的内容：

188CR-000A-000505
188CR-000S-001459

我做错了什么？请帮忙。

谢谢。

这是我的整个存储过程：

ALTER PROCEDURE [dbo].[sp_getOutlookDetails]

@CommunityName nvarchar(max),
@AdIDNumber nvarchar(max)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;

DECLARE @dbName nvarchar(max);
-- remove spaces
SET @CountryName = LOWER(REPLACE(@CountryName, ' ', ''));
SET @CommunityName = LOWER(REPLACE(@CommunityName, ' ', ''));


SET @dbName = @CountryName;
IF @CommunityName IS NOT NULL
    SET @dbName = @dbName+'_'+@CommunityName;

IF DB_ID(@dbname) IS NULL
    BEGIN
    RAISERROR('Database not found',16,1)
    RETURN
    END

DECLARE @MapCategory nvarchar(max);
DECLARE @VMEnabled INTEGER;

UPDATE @tab SET MapCategory = @MapCategory;
UPDATE @tab SET VMEnabled = @VMEnabled;
SELECT * FROM @tab;

Answer 1

也许是这样的：

DECLARE @AdIDNumber VARCHAR(MAX)
SET @AdIDNumber='188CR-000O-000199'
DECLARE @REVERSE VARCHAR(MAX)=REVERSE(@AdIDNumber)
select REVERSE(LEFT(@REVERSE,CHARINDEX('-',@REVERSE)-1))

Answer 2

它是由sp_getMapCategory存储过程引起的。

从字符串转换为uniqueidentifier错误时转换失败
