From b6d0101f10dea5a9fc0523cbe4dad9c2789bfae5 Mon Sep 17 00:00:00 2001 From: Fridolyn SOMERS Date: Thu, 21 Feb 2013 11:58:59 +0100 Subject: [PATCH] Bug 9681: Add some indexes in database Some table columns should have an index to speed SQL queries : - statistics table has only one index (used to make heavy queries for reports) - itemtype should have an index in items and biblioitems (this is used in circulation to check the number of existing issues of a specific item type) - issue.branchcode and issue.issuingbranch Test plan : - Create a new database using kohastructure.pl => check there is no SQL error and that new indexes are present (mysql> show create table) Apply update database on a master version => check there is no SQL error and that new indexes are present (mysql> show create table) --- installer/data/mysql/kohastructure.sql | 22 +++++++++++++-- installer/data/mysql/updatedatabase.pl | 46 ++++++++++++++++++++++++++++++++ 2 files changed, 66 insertions(+), 2 deletions(-) diff --git a/installer/data/mysql/kohastructure.sql b/installer/data/mysql/kohastructure.sql index ed673da..f3264e6 100644 --- a/installer/data/mysql/kohastructure.sql +++ b/installer/data/mysql/kohastructure.sql @@ -184,6 +184,7 @@ CREATE TABLE `biblioitems` ( -- information related to bibliographic records in PRIMARY KEY (`biblioitemnumber`), KEY `bibinoidx` (`biblioitemnumber`), KEY `bibnoidx` (`biblionumber`), + KEY `itemtype_idx` (`itemtype`), KEY `isbn` (`isbn`), KEY `issn` (`issn`), KEY `publishercode` (`publishercode`), @@ -657,6 +658,7 @@ CREATE TABLE `deletedbiblioitems` ( -- information about bibliographic records t PRIMARY KEY (`biblioitemnumber`), KEY `bibinoidx` (`biblioitemnumber`), KEY `bibnoidx` (`biblionumber`), + KEY `itemtype_idx` (`itemtype`), KEY `isbn` (`isbn`), KEY `publishercode` (`publishercode`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
