NPE when using a QueryString that uses ? for host variables.
--------------------------------------------------------------
Key: TUSCANY-18
URL: http://issues.apache.org/jira/browse/TUSCANY-18
Project: Tuscany
Type: Bug
Environment: Windows XP Pro, Eclipse 3.2M4 , jdk 1.5, 1/23/2006 tuscany DAS
code stream. (build locally), Derby 10.1
Reporter: Ying Chen
Priority: Minor
This only happens for select queries... Insert, update, delete does not have
the problem.
I have code snippet
Command select = Command.FACTORY.createCommand("Select
* from CUSTOMERS where CUSTOMERID = ? ");
select.setConnection(getConnection);
select.setParameterValue(1, new Integer(2) );
DataObject root = select.executeQuery();
When executeQuery() is called, I get an NPE..from
QueryString.getParameterIndex().
Note that the same query works when its replace text? host variable :
Command select = Command.FACTORY.createCommand("Select
* from CUSTOMERS where CUSTOMERID = :CUST ");
select.setConnection(getConnection);
select.setParameterValue("CUST", new Integer(2) );
DataObject root = select.executeQuery();
The trace stack is as follows:
java.lang.NullPointerException
