I query SELECT usename FROM pg_user WHERE usename ~* 'star_.*'; in the psql
command line. I get a result in the command line, but not one when I do the
same query in jdbc. It seems to screw up when I do a WHERE query.
I am only expecting 1 result to come back, but in the java code as seen below,
the rs is empty. So rs.next() == false.
ResultSet rs;
rs = null;
rs = this.executeQuery(SELECT usename FROM pg_user WHERE usename ~*
'star_.*')l
CarrotData.instance().assert("this i cannot allow (having a null
ResultSet)!", rs != null);
while (rs.next()) {
ret.addElement(rs.getString("usename"));
}
} catch (SQLException e) {
CarrotData.instance().error(e);
}
Thanks
Matt
