Actually, I think this change has a consequence for this method
in the same class:
public boolean isDefinitelyWritable(int column)
throws SQLException
{
return isWritable(column);
}
This is from the JDBC spec
(http://java.sun.com/j2se/1.3/docs/api/java/sql/ResultSetMetaData.html):
isReadOnly() - Indicates whether the designated column is
definitely not writable.
isWritable() - Indicates whether it is possible for a write on
the designated column to succeed.
isDefinitelyWritable() - Indicates whether a write on the
designated column will definitely succeed.
At this time we don't really implement the fine semantics of
these methods. I would suggest the following defaults:
isReadOnly() false
isWritable() true
isDefinitelyWritable() false
And that would mean that your patch is correct, but
isDefinitelyWritable() would need to be patched accordingly:
public boolean isDefinitelyWritable(int column)
throws SQLException
{
return false;
}
Again, both in jdbc1 and jdbc2.
