9.2.0 OCCI's setString Won't Work, Need Help w Thks

Question

Start exploring occi.h (oracle version 9.2.0) but hit a problem w no clue to solve it.
#include <iostream>
#include <occi.h>
using namespace oracle::occi;
using namespace std;
int main()
// declare Environment, Connection, ResultSet, Statement
env=Environment::createEnvironment(Environment::DEFAULT);
con=env->createConnection("myname", "mypws", "myConString");
stmt=con->createStatement("select * from aTable where aFld=:1 and bFld=:2");
stmt->setInt(1, 10);
stmt->setString(2, "myValue");
rs=stmt->executeQuery();
rs->next();
// cout result, all fields empty, seems a result not found
stmt=con->createStatement("select * from aTable where aFld=10 and bFld='myValue'");
rs=stmt->executeQuery();
rs->next();
// cout result, got the record and print expected result.
// close connection on env, rs, stmt, con
the diff. between 1st & 2nd SQL stmt is one is parameterize and the other is not. If in 1st SQL stmt, I hard code :2 to 'myValue' and then execute setInt() only, it works as well. So it is the 'setString()' function that won't work.
Any idea?
You help is really appreciated.
Thanks

Hi Nikeda
The bFld is in char(10).
You are correct, so when I change the sql stmt to "select * from aTable where aFld=:1 and trim(bFld)=:2", it works. Or when I change "myValue" to "myValue<+ 3 space", it works as well.
Thanks
