I didn't tell her to use INNER JOIN, just use '=' instead. and It can make a difference.

>>>Howdy,
>>>I'm using VFP5.0a.

>>>I've got a view that looks like this: create sql view "lvclientcharges" as select trim(clast)+', '+trim(cfirst),csac_id,chosp_id,dbirth,dcontact,nclient_id from clients where nclient_id in (select nclient_id from charge_visits) order by clast,cfirst
>>>
>>>The Clients table has 49,000ish records and has indexes on the nclient_id and deleted() and cfirst and clast fields - to name a few. The Charge_visits table has 41,000ish records with indexes on nClient_id and deleted() also to name a few. This view takes at least 1 minute to run. I'd like to speed it up. Any ideas?

>>>TIA
