处理前的查询结果如上图：

 

通过借助SQL变量的定义

DECLARE @Scope varchar(1000)DECLARE @Num int SET @Scope=‘‘SET   @Num = 1   SELECT @Scope=@Scope+convert(varchar(8),@Num)+‘、‘+DescScope+ DescOper+‘;‘, @Num = @Num+1 From fuel_contractQualityNew Where ContractID=‘012009000100‘SELECT ContractID,@Scope FROM fuel_contractQualityNew Where ContractID=‘012009000100‘ GROUP BY ContractID

 

 

实现了一下效果：

  //创建拼接描述SQL的函数CREATE FUNCTION dbo.f_str(@contractID varchar(50))RETURNS VARCHAR(8000)ASBEGIN        DECLARE @Scope varchar(1000)        DECLARE @Num int         SET @Scope=‘‘        SET   @Num = 1           SELECT @Scope=@Scope+convert(varchar(8),@Num)+‘‘+DescScope+ DescOper+‘;‘, @Num = @Num+1 From fuel_contractQualityNew where ContractID= @contractID        RETURN @ScopeENDGO
