How to get values from xml in SQL Server 2012 -


i have table 9000 rows , need every row need values , name values xml.

table columns: eaid, created, attachedapplication

xml:

<namedapplication xmlns:xs="http://www.w3.org/2001/xmlschema-instance">     <mainpart>         <firstname>john</firstname>         <surname>smith</surname>         <extras />     </mainpart> </namedapplication>

i can't results in table. name , surname resulted null

try this:

select     eaid,     firstname = xc.value('(firstname)[1]', 'varchar(100)'),     surname = xc.value('(surname)[1]', 'varchar(100)')     dbo.yourtablename cross apply     attachedapplication.nodes('/namedapplication/mainpart') xt(xc)

this "enumerate" on table, returning eaid column, , "reach into" xml , grab <firstname> , <surname> nodes within xml , expose them separate columns in output.

update: if run example uses table variable - work , return values??

declare @table table (eaid int, created date, attachedapplication xml)  insert @table (eaid, created, attachedapplication) values (1, getdate(),     '<namedapplication xmlns:xs="http://www.w3.org/2001/xmlschema-instance">     <mainpart>         <firstname>john</firstname>         <surname>smith</surname>         <extras />     </mainpart> </namedapplication>')  select     eaid,     firstname = xc.value('(firstname)[1]', 'varchar(100)'),     surname = xc.value('(surname)[1]', 'varchar(100)')     @table cross apply     attachedapplication.nodes('/namedapplication/mainpart') xt(xc)
