Bug 14053 - Acquisition db tables are missing indexes
Acquisition db tables have a lot of relational constraints and are often
missing an index to have performance queries.
This patch adds an index for all columns used in a forein key.
Also adds an index on some columns very often used in search queries :
aqbooksellers.name and aqbudgets.budget_code.
Also adds an index on aqorders.orderstatus, very often used with hardcoded
value like 'cancelled', in various queries.
Test plan :
- Check SQL syntax is correct
- Try to compare performance after and before database update. I think query
contained in C4::Acquistion::GetInvoices could be a good example
