这是一段关于存储过程分页的代码，，用Row_NUMBER 实现，， 其中 [dbo].[F_T_USER_IN_ROLE_S_SCHEMEROLE_BY_USERID]  为SQL Concatenate的实现。

 下面介绍几种实现该方法的代码。。

 1 CREATE FUNCTION [dbo].[F_T_USER_IN_ROLE_S_SCHEMEROLE_BY_USERID]

 2 

 3 (

 4 

 5        @USER_ID VARCHAR(50)

 6 

 7 )

 8 

 9 RETURNS VARCHAR(1000)

10 

11 AS

12 

13   BEGIN

14 

15        DECLARE @SchemeRole VARCHAR(1000) = ''

16 

17 

18 

19        SELECT @SchemeRole = @SchemeRole + s.SCHEME_NAME + '-' + r.ROLE_NAME + ';<br/>'

20 

21        FROM dbo.T_USER_IN_ROLE AS ur

22 

23        INNER JOIN dbo.T_SCHEME AS s ON ur.SCHEME_ID = s.SCHEME_ID

24 

25        INNER JOIN dbo.T_IC_ROLES AS r ON ur.ROLE_ID = r.ROLE_ID

26 

27        WHERE ur.USER_ID = @USER_ID and ur.IS_DELETED=0

28 

29 

30 

31     RETURN @SchemeRole

32 

33   END

这段感觉是比较好的  至少比下面哪种取xml的方法好得多。。 但还是介绍一下。。

SELECT     

         USER_ID,

  STUFF

  ((SELECT ';' +  (CAST(ROLE_NAME AS VARCHAR(MAX))+','+CAST(SCHEME_CODE AS VARCHAR(MAX)))

    FROM V_USER_INFO_ROLE_SCHEME

    WHERE 

     (USER_ID = Results.USER_ID)

    FOR 

     XML 

     PATH ('')),1,1,''

  ) AS SCHEME_ROLE



     FROM [V_USER_INFO_ROLE_SCHEME]  as Results  group by  USER_ID
