Marcel de Rooy <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #162012|0 |1 is obsolete| | --- Comment #7 from Marcel de Rooy <[email protected]> --- Created attachment 163659 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=163659&action=edit Bug 36033: Add more indexes to table pseudonymized_transactions Table pseudonymized_transactions contains : KEY `pseudonymized_transactions_ibfk_1` (`categorycode`), KEY `pseudonymized_transactions_borrowers_ibfk_2` (`branchcode`), KEY `pseudonymized_transactions_borrowers_ibfk_3` (`transaction_branchcode`) To improve SQL queries performance, it needs more indexes, specially on itemnumber. Looking at table statistics : KEY `timeidx` (`datetime`), KEY `branch_idx` (`branch`), KEY `type_idx` (`type`), KEY `itemnumber_idx` (`itemnumber`), So index is need on pseudonymized_transactions columns : itemnumber => For join with table items transaction_type => For filter on type issue, return ... datetime => For filter on date, this will help cleanup script Test plan : 1) Run updatedatabase.pl 2) Check indexes are created in table pseudonymized_transactions 3) Run SQL query : describe select * from pseudonymized_transactions join items using(itemnumber) where transaction_type='issue' and datetime < date_sub(curdate(), INTERVAL 30 DAY) => You see the 3 new indexes used in 'possible_keys'.
