ADOQuery SQL und REPLACE

[sniper_w]

Wenn ich folgende SQL-Statement ausführe, bekomme ich das Resultat wie im anhang.

SQL-Code:

USE [Test]
GO
/****** Object:  Table [dbo].[CallDetail]    Script Date: 10/27/2009 14:51:25 ******/
IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[CallDetail]') AND type in (N'U'))
DROP TABLE [dbo].[CallDetail]
GO
/****** Object:  Table [dbo].[CallDetail]    Script Date: 10/27/2009 14:51:16 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[CallDetail](
   [LocalUser] [nvarchar](50) NOT NULL,
   [LocalNumber] [nvarchar](50) NOT NULL,
 CONSTRAINT [PK_CallDetail] PRIMARY KEY CLUSTERED 
(
   [LocalUser] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

INSERT INTO [CallDetail] ([LocalUser], [LocalNumber]) VALUES ('UserName1', '123')
INSERT INTO [CallDetail] ([LocalUser], [LocalNumber]) VALUES ('UserName2', '%0UNKNOWNNUMBER0%')

SELECT [LocalUser]
      ,[LocalNumber]
  FROM [dbo].[CallDetail]

SELECT [LocalUser]
      , Replace(LocalNumber,'0UNKNOWNNUMBER0','unbekannt') AS LocalNumber 
  FROM [dbo].[CallDetail]

Select
  LocalUser,
  case when CHARINDEX('0UNKNOWNNUMBER0', LocalNumber) > 0 then
    Replace(LocalNumber,'0UNKNOWNNUMBER0','unbekannt') else LocalNumber end AS LocalNumber
from
  CallDetail

Dein Problemm scheint wo anders zu sein, weil SQL-Behfele funktionieren wie gewollt.
