Subject: [PATCH] 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.
