前言：
现时看官们对“oraclesql字段合并”可能比较看重，各位老铁们都需要剖析一些“oraclesql字段合并”的相关资讯。那么小编在网络上收集了一些关于“oraclesql字段合并””的相关内容，希望大家能喜欢，咱们快快来学习一下吧！方案一：
Create FUNCTION [dbo].Get_Contract_StyleNo(@AutoInc bigint)
RETURNS VARCHAR(Max)
AS
BEGIN
DECLARE @Content NVARCHAR(MAX)
SET @Content = ''
SELECT @Content = case when @Content='' then '' else @Content + ',' end + GoodsNo
FROM (select distinct GoodsNo from EXP_Contract_Clothing_Goods where MainID=@AutoInc) m
RETURN @Content
END
GO
构造标量函数
使用xml
构造通用存储过程
方案三：
------默认条件，MainID=AutoInc
alter procedure [dbo].[SP_SumStr]
(
@MTable Varchar(100) --主表
,@ZTable Varchar(100) --子表
,@MColumn Varchar(100) --主表更新字段
,@ZColumn Varchar(100) --子表拼接字段
,@ConditionSql Varchar(500) --传入的条件语句
)
as
set nocount on
begin
declare @strSql varchar(3000)
select top 1 AutoInc as MainID, Convert(nvarchar(500),CnName) as GoodsNo
into #result
from SYS_Staff where 1<0
set @strSql = 'insert into #result select distinct MainID,'+ @ZColumn +' from '+@ZTable+' ' + @ConditionSql
exec(@strSql)
DECLARE @Content NVARCHAR(MAX)
SET @Content = ''
SELECT @Content = case when @Content='' then '' else @Content + ',' end + GoodsNo FROM #result
set @strSql = 'Update a set a.'+@MColumn+'='+@Content+' from '+ @MTable +' a left join '+@ZTable+' b on a.AutoInc=b.MainID ' + @ConditionSql
exec(@strSql)
----SELECT @Content
end
set nocount off
