Here is a patch for interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java

It addresses three issues: 1. The problem with ResultSet's interface specifying 1-based indexing was not quite fixed in 7.0.2. absolute would stop the user form moving to the first record (record 0 internally). 2. Absolute did not set current_row 3. For field.mod=-1, GetObject would try to return numeric values with a precision of around 65000. Now GetObject detects when field.mod==-1, and passes that as the scale to getBigDecimal. getBigDecimal detects when a -1 is passed and simply does not scale the value returned. You still get the correct value back, it simply does not tweak the precision. I'm working off of a source tree I just checked out from the repository. The diff is based on what was in the repository about ten minutes ago. ---------------------------------------------------------------- Travis Bauer | CS Grad Student | IU |www.cs.indiana.edu/~trbauer ----------------------------------------------------------------
