I am getting a BINDING ERROR when trying to use my own sql in a data retrieval rule.
Oracle 10g ns 2008.3 SP7 Websphere 6.1
The field name is REQUISITION_TASKS.RIT
the SQL is "select 'With '||firstname||' '|| CASE SUBSTR(lastname,1,1) WHEN '<' THEN ' ' ELSE lastname END||' to do the task - '||subject ||' and is due on - '||DUEON REQ, 'Ongoing tasks listed below' YESREC from TxActivity ,dirperson where ActivityID IN (SELECT DISTINCT ActivityID FROM TxActivity where TicketID IN (SELECT DISTINCT RequisitionEntryID FROM TxRequisitionEntry WHERE RequisitionID IN ('#REQUISITION_TASKS.RIT#')) ) and (stateid = 2 OR stateid = 6) and waiting = 0 AND performerid = personid
This works fine in SQL plus (as long as I replace #REQUISITION_TASKS.RIT# with a valid Requisition. When I perform the data retrieval, I get the error...
System error :[newScale][Oracle JDBC Driver] Invalid parameter binding(s).
I had some trouble using a parameter Inbound SQL field of the adapter as well and I wondered if you could even use a parameter in that location. I know that you can use parameters in the InboundFailureSQl and InboundSuccessSQL but those parameters are references to fields that were pulled using the initial select statement. The manual is not very clear on the use of parameters in the database adapter.
We've found the SQL engine to be pretty weak in that it only really allows pretty simple Select statements. One of the suggestions from Leslie was to use SQL functions; so you can code a more complex function that takes parameters and spits results back in the DB itself and then call it using the data retrieval configuration.
Eg, we use common-table-expressions in SQL to obtain the details of a users manager (as the org structure and hierarchies aren't available through the directory). We have a function in the database called 'findmanager(x,y)' which takes 2 parameters and returns 4-5 pieces of information we need to route the authorisation.
You could do something similar with coding a function to take the parameters from the Order form (or constants) and then have it send back the right info. Hope this helps!
