0029543: slow query for orders

DescriptionWhile doing a system sizing guideline a slow query in WebPOS was encountered (on the server) which was particurarly slow, and easy to make faster [1].

Several things where noted:
- several queries are fired after eachother, so there seems to be no delay while the user types (so not related to the sql, but still wanted to mention it)
- the query has 2 like clauses, only the one replacing the \ is enough
- like clauses with a percentage as a start will never use an index
- where clauses with functions will never use an index (hopefully as part of the store server project this can be changed)
- this subquery showed to have a great impact:
(select count(orderlinel3_.QtyDelivered) from C_OrderLine orderlinel3_ where order0_.C_Order_ID=orderlinel3_.C_Order_ID and orderlinel3_.QtyDelivered<>0)>0
changing it to:
exists (select 1 from C_OrderLine orderlinel3_ where order0_.C_Order_ID=orderlinel3_.C_Order_ID and orderlinel3_.QtyDelivered<>0)
makes it the whole query more than 10 times faster! The query went from 6.5 seconds to 500 millis
- also there are 2 count subqueries, would only querying on delivered quantity be enough?

I will enter an issue for it.
