SQL服务器：表值函数不与子查询

Question

我有创建一个SQL Server表值函数由我，我已经粘贴下面

CREATE FUNCTION [dbo].[getTableFromString] 
(  
    @String AS nvarchar(max) 

) 
RETURNS @ReturnTable TABLE (StringValues nvarchar(10) ) 
AS begin 

    if (SELECT CHARINDEX(',', @String)) = 0 
     begin 
       insert into @ReturnTable (StringValues) values (subString(@String,1,len(@String))); 
     end 
    else 
     begin 
      while (SELECT CHARINDEX(',', @String)) > 0 
      begin 
       insert into @ReturnTable (StringValues) values (subString(@String,1,CHARINDEX(',', @String)-1)); 
       set @String = subString(@String,CHARINDEX(',', @String)+1,len(@String)); 

       if (SELECT CHARINDEX(',', @String)) = 0 
       begin 
         insert into @ReturnTable (StringValues) values (subString(@String,1,len(@String))); 
       end   
      end 
     end 

    return ; 
end 

创建脚本，我使用此功能工作像下面

Select sum(NetSales) 
from vwxsalesall 
where Company = 'rs' 
and storecode = (select cPrimaryStockRoomCode from CompanyMaster.CompanyProfileDetail where cCompanyNo = 'rs' and cSecondaryStockRoomCode = 'R01B') 
and trandate >= '2012-01-01' 
and trandate <= '2012-01-31' 
and ( 
     brand in ( 
        select StringValues from dbo.getTableFromString(
                    select vIncludedBrandCodes 
                    from StockRoomTargetData.MonthlyTarget 
                    where cCompanyNo = 'rs' 
                    and cSecondaryStockRoomCode = 'R01B' 
                    and nYear = 2012 
                    and nMonth = 8 
                    ) 
       ) 
    ) 

不幸的是，我得到这个错误

消息156，15级，状态1，10号线
关键字'select'附近的语法不正确。
消息102，级别15，状态1，行16
附近有语法错误 '）'。

请帮我

您需要添加另一组围绕子查询括号，例如

select StringValues from dbo.getTableFromString(({ your-subquery })) 

               ^    ^
               (parenthesis added) 

第一套parenthessis的语法属于TVF调用，并表示第二子查询。

现在查询：

Select sum(NetSales) 
from vwxsalesall 
where Company = 'rs' 
and storecode = (select cPrimaryStockRoomCode from CompanyMaster.CompanyProfileDetail where cCompanyNo = 'rs' and cSecondaryStockRoomCode = 'R01B') 
and trandate >= '2012-01-01' 
and trandate <= '2012-01-31' 
and ( 
     brand in ( 
        select StringValues from dbo.getTableFromString((
                    select vIncludedBrandCodes 
                    from StockRoomTargetData.MonthlyTarget 
                    where cCompanyNo = 'rs' 
                    and cSecondaryStockRoomCode = 'R01B' 
                    and nYear = 2012 
                    and nMonth = 8 
                    )) 
       ) 
    )
