Back in the day when our contract with our former ILS vendor limited us to < 500K titles it became necessary to put several non-circulating titles into a separate MySQL db named Louisa.
Louisa has x db tables:
mysql> describe titles;
+------------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+----------------+
| mrc | mediumtext | YES | | NULL | |
| tcn | varchar(20) | YES | | NULL | |
| ckey | int(11) | YES | | NULL | |
| createDate | date | YES | | NULL | |
| titleID | int(11) | NO | PRI | NULL | auto_increment |
+------------+-------------+------+-----+---------+----------------+
mysql> describe items;
+------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+--------------+------+-----+---------+----------------+
| cnA | varchar(100) | YES | | NULL | |
| cnD | varchar(50) | YES | | NULL | |
| cnType | varchar(10) | YES | | NULL | |
| collection | varchar(15) | YES | | NULL | |
| barcode | varchar(15) | YES | | NULL | |
| hLocation | varchar(20) | YES | | NULL | |
| cLocation | varchar(10) | YES | | NULL | |
| itemType | varchar(10) | YES | | NULL | |
| titleID | int(11) | YES | | NULL | |
| ckey | int(11) | YES | | NULL | |
| createDate | date | YES | | NULL | |
| itemID | int(11) | NO | PRI | NULL | auto_increment |
+------------+--------------+------+-----+---------+----------------+
12 rows in set (0.01 sec)
After these titles and items are in FOLIO their MARCs will need to be re-written with FOLIO 999s and added to the records db table so before loading them into FOLIO they should be added to the marcRecords and itemData MySQL tables (see Parse) from whence bibLoad.pl should be able to do what needs to be done. So, the trick is going to be to write a Louisa2?.pl script to get that job done.
