MSSql表列拼接成字符串简析

将表列拼接成字符串。闲话不多说切入正题，看代码：

[sql]

select STUFF(

REPLACE( www.2cto.com

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：将表转化为xml格式

[sql]

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 www.2cto.com

第二步：替换<N pc=" 注：N是表名，pc是列名

[sql]

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：替换 "/> 注：每项都会以“<表字段”开始，以“ "/>”结束

[sql]

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="','+'),'"/>','')

最后使用：STUFF() 函数作用：删除指定长度的字符，并在指定的起点上插入另外的字符串

[sql]

select STUFF(

REPLACE( www.2cto.com

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
