Subject: Improve error handling in marc2sre.pl when bib ID is not found
X-Git-Url: http://git.equinoxoli.org/?p=evergreen-equinox.git;a=commitdiff_plain;h=444ebc935bb8ddc37312a308c2efa797a2cb2b3b

Improve error handling in marc2sre.pl when bib ID is not found

If we can't find a bibliographic record ID to use in our load, then
skip that MFHD record and move on to the next one. Using the counter
gives sites a chance to identify which record caused the problem.

Aside: bitmap index scans for leading '%' LIKE searches make the
--bibfield / --bibsubfield extremely slow in large datasets. If
at all possible, avoid this path!
