我在SQL Server的XML列中有以下XML。
<qualifiers> <qualifier> <key>111</key> <message>a match was not found</message> </qualifier> <qualifier> <key>222</key> <message>a match was found</message> </qualifier> <qualifier> <key>333</key> <message>error</message> </qualifier> </qualifiers>
如何编写TSQL以逗号分隔的字符串返回限定符/限定符/消息中的所有值?我的目标是让查询在每一行的单个列中返回XML中的值。
结果应如下所示:
"a match was not found, a match was found, error"
SQLFiddle的相同之处:建议按照@xQbert的解决方案
create table Temp (col1 xml) go insert into Temp (col1) values('<qualifiers> <qualifier> <key>111</key> <message>a match was not found</message> </qualifier> <qualifier> <key>222</key> <message>a match was found</message> </qualifier> <qualifier> <key>333</key> <message>error</message> </qualifier> </qualifiers>') go SELECT STUFF((SELECT ',' + fd.v.value('(.)[1]', 'varchar(50)') FROM Temp CROSS APPLY col1.nodes('/qualifiers/qualifier/message') AS fd(v) FOR XML PATH('') ), 1, 1, '')
