Re: SQL Performance issues questions

[Paul Bailey <PabloMotte+Midrange@xxxxxxxxx>]

You probably don't want to create the indexes right from Visual Explain
(VE). You might want to get the SQL CREATE INDEX statement from VE, put it
into a source file and then run it through your own change management
processes. I've learned from experience that creating an index straight
from VE leads to a lot of confusion within the dev team.
