Database Adapter ResultSet in BPEL Processing

Question

Hi
I have an issue regarding processing a result set in BPEL. My DBAdpater returns a number of rows from a given stored procedure call and it is not that obvious, from the documentation, on how to process the results set one at a time, for example in a while loop.
I have a strongly typed xsd created ready to process and I can count the number of rows returned. The question is, how do I iterate over the results set?
Btw, I am using 11.1.1.5 SOA Suite.
Any help would be much appreciated, pointers to appropriate documentation etc.
Cheers
Matt

Answer 1

Hi Matt,
You have to use while loop for this.
1.) Create 2 variables, totalCount and counter of int type
2.) Use Assign and assign counter=0 and use ora:countNodes(resultset)
to get the total number of nodes return or number of records returned from the DB
3.) In the while loop use condition
totalCount>counter
4.) Use Assign activity and fetch the data u want to, [$counter]
see example below
bpws:getVariableData('info','/ns3:emp[$counter]/ns3:age')
example:
<info>
<emp>
<name>Tom</name>
<age>21</age>
</emp>
<emp>
<name>Tom</name>
<age>21</age>
</emp>
<emp>
<name>Tom</name>
<age>21</age>
</emp>
</info>
5.) Use assign activity and append value of counter=counter+1
