Dynamic XML node name in SQL XML - sql

Question

I am updating an XML column with values from columns in a temp table. I can update the table as below.
UPDATE tbWorkflow
SET xmlData.modify('insert
(<FromQueueName>
<CustomerID>{ sql:column("T.iVTollCustID") }</CustomerID>
<Date>{ sql:variable("#CurrDateTime") }</Date>
</FromQueueName>)
as first into (/configuration)[1]'),
vcQueue = 'qVtoll',
dtUpdTime = GETDATE()
FROM #Trxns T
WHERE T.biWorkflowID = tbWorkflow.biWorkflowID
However, I want the node name to be dynamic (from the temp table) like below. But it does not work.
UPDATE tbWorkflow
SET xmlData.modify('insert
(<**{ sql:column("T.vcQueue") }**>
<CustomerID>{ sql:column("T.iVTollCustID") }</CustomerID>
<Date>{ sql:variable("#CurrDateTime") }</Date>
</**{ sql:column("T.vcQueue") }**>)
as first into (/configuration)[1]'),
vcQueue = 'qVtoll',
dtUpdTime = GETDATE()
FROM #Trxns T
WHERE T.biWorkflowID = tbWorkflow.biWorkflowID
Any help is appreciated.

Answer 1

I think, you should use a subquery to select a string you need and then insert it into XML.
For example, in subquery get a <YourTag><CustomerID>123</CustomerID><Date>15.10.2012</Date></YourTag> and then you can simply insert it in XML

I found a workaround to do this.
I added another VARCHAR column to my temp table, created the xml node as a varchar and later modified my actual xml column using this varchar column.
UPDATE #Trxns
SET xmlVarchar = '<' + vcQueue + '>
<CustomerID>' + CONVERT(VARCHAR(10),iVTollCustID) + '</CustomerID>
<Date>' + CONVERT(VARCHAR(25), GETDATE(),22) + '</Date>' +
'</' + vcQueue + '>'
UPDATE tbWorkflow
SET xmlData.modify('insert
sql:column("xmlVarchar")
as first into (/configuration)[1]'),
vcQueue = 'qVtoll',
dtUpdTime = GETDATE()
FROM #Trxns T
WHERE T.biWorkflowID = tbWorkflow.biWorkflowID
