This jdbc is messing up on basic select/where queries. For example:
SELECT usename FROM pg_user WHERE usename ~* 'star_.*';
usename
---------
star_admin
But in jdbc I do:
SELECT usename FROM pg_user WHERE usename ~* 'star_.*';
I get an empty result set.
rs.next() is false.
What would be causing this?

Probably the backend. What do you get if you run this query from psql?
JDBC currently does nothing to the SQL before passing it to the backend.

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
