SQL SERVER2000将多行查询结果拼接到一行数据

Posted 2020-09-28 AmourOnce

 

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)
AS
BEGIN
        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 @Scope
END
GO
