RE: [jira] Created: (BEEHIVE-1203) JdbcControl & Foxpro - Data notreturned by PreparedStatement
Was wondering if there have been any thoughts on this issue?
Has anyone else reproduced this problem or discovered any problems with
my fix?
Cheers

JdbcControl & Foxpro - Data not returned by PreparedStatement
-------------------------------------------------------------
Key: BEEHIVE-1203
URL: https://issues.apache.org/jira/browse/BEEHIVE-1203
Project: Beehive
Issue Type: Bug
Components: System Controls
Environment: Windows XP
Beehive 1.0.2
HXTT Fox pro jdbc driver (3.0)
Tomcat 5.5
Apache commons connection pool
(org.apache.commons.dbcp.BasicDataSourceFactory)
Reporter: Steven Dalton
When attempting to retrieve data from the foxpro database, the ResultSet
(or Object) from the PreparedStatement was null.
By recreating as many conditions for the PreparedStatement as provided
by the JdbcControl, I discovered that the getting of the update count
before getting the ResultSet was the cause.
I moved the ps.getUpdateCount() method until after the ps.getResultSet()
method call and the data was returned.
Unfortunately I can't determine the reason for the problem (suspect a
problem with the driver), but the problem is fixed using the change
below.
SQLServer database actions continue to work as expected with this
change. Not sure about other databases.
Changed from
//
// process returned data
//
ResultSet rs = null;
int updateCount = ps.getUpdateCount();
if (hasResults) {
rs = ps.getResultSet();
}
to
//
// process returned data
//
ResultSet rs = null;
int updateCount = -1;
if (hasResults) {
rs = ps.getResultSet();
}
updateCount = ps.getUpdateCount();
