[msSql]表列拼接成字符串

時事造英雄，實踐長知識。深夜中還在公司加班，這週週末過得有點累。不過還是想分享下剛剛的知識：將表列拼接成字符串。閒話不多說切入正題，看代碼：

select  STUFF(
		REPLACE(
			REPLACE(
				(select  fieldName as pc from cj_datadictionary as N
				join [CSD_ORD_PayMent]  on costsid=fieldCode and fieldType='OP' where memberid=72157 and groupID='201205DD2119416553' and [Expenditure]>0 
				FOR XML AUTO),'<N pc="','+'
			),'"/>',''
		),1,1,''
	)

第一步：將錶轉化爲xml格式

			select  fieldName as pc from cj_datadictionary as N
			join [CSD_ORD_PayMent]  on costsid=fieldCode and fieldType='OP' 
			where memberid=72157 and groupID='201205DD2119416553' and [Expenditure]>0 
			FOR XML AUTO

第二步：替換<N pc=" 注：N是表名，pc是列名

			select REPLACE((select  fieldName as pc from cj_datadictionary as N
			join [CSD_ORD_PayMent]  on costsid=fieldCode and fieldType='OP' 
			where memberid=72157 and groupID='201205DD2119416553' and [Expenditure]>0 
			FOR XML AUTO),'<N pc="','+')

第三步：替換 "/> 注：每項都會以“<表 字段”開始，以“ "/>”結束

			select REPLACE(REPLACE((select  fieldName as pc from cj_datadictionary as N
			join [CSD_ORD_PayMent]  on costsid=fieldCode and fieldType='OP' 
			where memberid=72157 and groupID='201205DD2119416553' and [Expenditure]>0 
			FOR XML AUTO),'<N pc="','+'),'"/>','')

最後使用：STUFF() 函數作用：刪除指定長度的字符，並在指定的起點上插入另外的字符串

select  STUFF(
		REPLACE(
			REPLACE(
				(select  fieldName as pc from cj_datadictionary as N
				join [CSD_ORD_PayMent]  on costsid=fieldCode and fieldType='OP' where memberid=72157 and groupID='201205DD2119416553' and [Expenditure]>0 
				FOR XML AUTO),'<N pc="','+'
			),'"/>',''
		),1,1,''
	)

大功告成，打完收工，準備下班回家！
