I think so, too :)

So, I'm looking at src/include/utils/errcodes.h in CVS tip, and I see
what looks to me like two columns in a table:

sqlstate (e.g. 0100C)
warning (e.g. ERRCODE_WARNING_DYNAMIC_RESULT_SETS_RETURNED)

this would make an excellent table to have handy. How to make sure
that it is, in fact, available, and that its contents match
errcodes.h? Here is a perl hack for parsing errcodes.h:

#!/usr/bin/perl -wl

use strict;

open F, "<errcodes.h" or die "Can't open errcodes.h: $!";
while(<F>) {
chomp;
next unless (/^#define\s+ERRCODE_(\S+)\s+MAKE_SQLSTATE\('(.*)'\).*$/);
# print;
my ($warning, $sqlstate) = ($1, $2);
$warning =~ s/^ERRCODE_//;
$sqlstate =~ s/\W//g; # clean up
my $sql = "INSERT INTO sqlstates (sqlstate, warning) VALUES ($sqlstate, $warning);";
print $sql;
# Now, do the inserts...but where?
}

Cheers,
D
