From d6603e1334b31669aaa9ed201b95cec97bba9f46 Mon Sep 17 00:00:00 2001 From: Nicole C. Engard Date: Sun, 2 Oct 2011 02:11:06 -0400 Subject: [PATCH] Bug 6716 - Document Items Table This patch documents the items table. Some fields were left undocumented because I was unsure of what data was stored there: stack - might be linked to shelving number, but need confirmation paidfor - pretty sure this is unused, but don't want to document it that way --- installer/data/mysql/kohastructure.sql | 76 ++++++++++++++++---------------- 1 files changed, 38 insertions(+), 38 deletions(-) diff --git a/installer/data/mysql/kohastructure.sql b/installer/data/mysql/kohastructure.sql index 3a51df5..cdd7e78 100644 --- a/installer/data/mysql/kohastructure.sql +++ b/installer/data/mysql/kohastructure.sql @@ -996,46 +996,46 @@ CREATE TABLE `issuingrules` ( -- DROP TABLE IF EXISTS `items`; -CREATE TABLE `items` ( -
