Extracting data from XML Array using SQL - sql

Question

I have the following XML and would like to extract the PrimaryTeams, SecondaryTeams and OverflowTeams arrays from this and either have them comma separated or one per row.
I have the following xml:
declare #xml xml
set #xml = '<SimpleStrategy xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/Synthesys.Switch.ACD">
<Id>00000000-0000-0000-0000-000000000000</Id>
<Name>Default</Name>
<AcceptedCLIs xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<d2p1:string>07811353995</d2p1:string>
</AcceptedCLIs>
<ActiveHours>
<FridayEnd />
<FridayStart />
<MondayEnd />
<MondayStart />
<SaturdayEnd />
<SaturdayStart />
<SundayEnd />
<SundayStart />
<ThursdayEnd />
<ThursdayStart />
<TuesdayEnd />
<TuesdayStart />
<UseIndividualWeekDays>false</UseIndividualWeekDays>
<WednesdayEnd />
<WednesdayStart />
<WeekdayEnd />
<WeekdayStart />
</ActiveHours>
<AgentUserName />
<AllowRouteDuringFinalMessage>false</AllowRouteDuringFinalMessage>
<CRMPrefix />
<DirectDDIMessage />
<DirectDDIPassThrough>false</DirectDDIPassThrough>
<EmergencyBusyBack>false</EmergencyBusyBack>
<EmergencyDivertNumber />
<EmergencyWavFile />
<FinallyDivertNumber />
<FinallyDrop>true</FinallyDrop>
<FinallyMessageFile />
<MaximumQueueLength>0</MaximumQueueLength>
<MaximumQueueWait>0</MaximumQueueWait>
<MinimumRingTime>4000</MinimumRingTime>
<MusicOnHold />
<MusicWhileWaiting />
<NumberOfRings>2</NumberOfRings>
<OutOfHoursDivertNumber />
<OutOfHoursDrop>true</OutOfHoursDrop>
<OutOfHoursMessage />
<OverflowMessage />
<OverflowTeams xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays" />
<PrimaryTeams xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<d2p1:int>3</d2p1:int>
<d2p1:int>1</d2p1:int>
</PrimaryTeams>
<Priority>1</Priority>
<RecordAgent>false</RecordAgent>
<RecordCall>true</RecordCall>
<RecordCustomer>false</RecordCustomer>
<RegulatoryMessage>Default.wav</RegulatoryMessage>
<SecondaryOverflowMessage />
<SecondaryTeams xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays" />
<SendBusyIfQueueTooLong>false</SendBusyIfQueueTooLong>
<SendBusyIfWaitTooLong>false</SendBusyIfWaitTooLong>
<TimeInOverflow>-1</TimeInOverflow>
<TimeWithDirectDDI>20000</TimeWithDirectDDI>
<TimeWithPrimaryTeams>-1</TimeWithPrimaryTeams>
<TimeWithSecondaryTeams>20000</TimeWithSecondaryTeams>
<UseDirectDDI>false</UseDirectDDI>
<UsePAM>false</UsePAM>
<UseSecondaryTeams>false</UseSecondaryTeams>
<WrapTime>40000</WrapTime>
</SimpleStrategy>'
I then created the following SQL Statement to try and extract the Teams
;WITH XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema-instance' as i, 'http://schemas.microsoft.com/2003/10/Serialization/Arrays' as d2p1,
DEFAULT 'http://schemas.datacontract.org/2004/07/Synthesys.Switch.ACD')
SELECT #xml,
#xml.value('(/SimpleStrategy/Name)[1]', 'varchar(255)'),
#xml.value('(/SimpleStrategy/PrimaryTeams)[1]', 'int') as PrimaryTeams,
#xml.value('(/SimpleStrategy/SecondaryTeams)[1]', 'int') as SecondaryTeams,
#xml.value('(/SimpleStrategy/OverflowTeams)[1]', 'int') as OverflowTeams
But all I get is the TeamID's concatenated together.
,PrimaryTeams,SecondaryTeams,OverflowTeams
Default,31,0,0
Any ideas?
Thanks

Answer 1

Your XML shows two team IDs in <PrimaryTeams>, while both other team nodes are empty... You did not tell us anything about the expected counts in there. However, the following approach will return a kind of entity-value-pairs with all IDs for all Teams. Hope this is what you need:
;WITH XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema-instance' as i, 'http://schemas.microsoft.com/2003/10/Serialization/Arrays' as d2p1,
DEFAULT 'http://schemas.datacontract.org/2004/07/Synthesys.Switch.ACD')
SELECT 'Name' AS Caption
,1 AS RowInx
,#xml.value('(/SimpleStrategy/Name)[1]', 'varchar(255)') AS Content
UNION ALL
SELECT 'Primary Team'
,ROW_NUMBER() OVER(ORDER BY (SELECT NULL))
,t.value('.','varchar(255)')
FROM #xml.nodes('/SimpleStrategy/PrimaryTeams/d2p1:int') A(t)
UNION ALL
SELECT 'Secondary Team'
,ROW_NUMBER() OVER(ORDER BY (SELECT NULL))
,t.value('.','varchar(255)')
FROM #xml.nodes('/SimpleStrategy/SecondaryTeams/d2p1:int') A(t)
UNION ALL
SELECT 'Overflow-Team'
,ROW_NUMBER() OVER(ORDER BY (SELECT NULL))
,t.value('.','varchar(255)')
FROM #xml.nodes('/SimpleStrategy/OverflowTeams/d2p1:int') A(t);
