Troubleshooting
Problem
A query of XML data types in IBM DB2 in Rational Integration Tester (RIT) of IBM Rational Test Workbench gives the error: "Invalid operation: No data is retrieved for OUT parameter".
Symptom
You see an error such as the following.
[jcc][t4][10132][10859][3.63.123] Invalid operation: No data is retrieved for OUT parameter. ERRORCODE=-4472, SQLSTATE=null
Cause
DB2 is returning an XML object that RIT incorrectly interprets.
Diagnosing The Problem
- Test the query in IBM Data Studio, to verify that the query itself is valid.
- Review the returned data. If the data looks like the following output, you might have an XML object.
com.ibm.db2.jcc.am.oe@56805680
Resolving The Problem
WORKAROUND
Cast the data that the query returns to another type. The following example uses the XMLCAST option to cast the returned XML objects to the VARCHAR() data type.
