Add header record with column names while writing csv file fileAdapter?

Question

Hi I am writing the output of a query to csv file using fileadapter. but the file generated does not have the header record with the column names. how can I achieve this. please help.

Answer 1

I'm trying to do the same, but something is not right with my syntax and I haven't been able to resolve all day. Can someone spot what I'm doing wrong?
Here is the variable with the data I want to insert as the headers for the CSV:
Updated variable "CPARWebJEHeaders"
<CPARWebJEHeaders>
<Root-Element xmlns="http://xmlns.oracle.com/CPWebJEARWrite">
<CPARWebJE>
<Project>Project</Project>
<Organization>CC_Org</Organization>
<Account>Account</Account>
<TransactionAmount>Amount</TransactionAmount>
<TransactionDesc>Description</TransactionDesc>
</CPARWebJE>
</Root-Element>
</CPARWebJEHeaders>
Here is the InputVariable data for my invoke to the File Adapter:
[2008/03/24 15:27:30] Updated variable "WriteCPARWebJEFile_Write_InputVariable"
<WriteCPARWebJEFile_Write_InputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="Root-Element">
<Root-Element xmlns="http://xmlns.oracle.com/CPWebJEARWrite">
<ns0:CPARWebJE xmlns:ns0="http://xmlns.oracle.com/CPWebJEARWrite">
<ns0:Project>INV08-00002</ns0:Project>
<ns0:Organization>1.6.1.1.01</ns0:Organization>
<ns0:Account />
<ns0:TransactionAmount>176</ns0:TransactionAmount>
<ns0:TransactionDesc />
</ns0:CPARWebJE>
<ns0:CPARWebJE xmlns:ns0="http://xmlns.oracle.com/CPWebJEARWrite">
<ns0:Project>INV08-00001</ns0:Project>
<ns0:Organization>1.6.1.1.01</ns0:Organization>
<ns0:Account />
<ns0:TransactionAmount>305.46</ns0:TransactionAmount>
<ns0:TransactionDesc />
</ns0:CPARWebJE>
</Root-Element>
</part>
</WriteCPARWebJEFile_Write_InputVariable>
This is my latest iteration of the insertBefore command, which is done right after the transformation populating the variable above:
<bpelx:assign>
<bpelx:insertBefore>
<bpelx:from variable="CPARWebJEHeaders" query="/ns12:Root-Element/ns12:CPARWebJE"/>
<bpelx:to variable="WriteCPARWebJEFile_Write_InputVariable" part="Root-Element"/>
</bpelx:insertBefore>
</bpelx:assign>
And finally, here is the current error message:
<selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">
<part name="summary">
<summary>Assign Operation Misuse. The parent of the selection result does not exist or is not an XML element; insertBefore operation cannot be performed. Please check the BPEL source at line number "96" .</summary>
</part>
</selectionFailure>
I understand the error message, but for the life of me can't get it resolved. Trying to change the "to" variable, I can't even get the process to deploy. FYI this is on 10.1.2 and I can't go to 10.1.3 yet, but I think this is a syntax issue and not related to the version.
Thanks!
