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();
