Hi
Greg had very good advice that you may have missed if you have never used
SQL Profiler. SQL Profiler will show you the actual SQL code that is being
executed by the application (if it is inline SQL) or what Stored Procedures
are being called.
All this might be of limited usefulness if you don't have access to
programmers who can change poorly written code in the application. I am
thinking someone is perceiving "the appilcation is slow" and have decided to
kick the DB guy, when in fact the problem is with the application, Perhaps
the app is marching through ADO Recordsets to join data when it could be
done using basic SQL functionality.
For your original question if you have
MatterConflicts:
Fields: MatterConflicts varchar(16), Matters varchar(16), HitMatters
varchar(16), IsInclude varchar(1)
Index: MatterConflicts
MatterConflictHits:
Fields: MatterConflictHits varchar(16), MatterConflicts varchar(16),
ColumnLabel varchar(40), Hit varchar(100)
Index: MatterConflictHits
MatterConflicts.MatterConflicts should be the Primary key of MatterConflicts
( think you said it was)
MatterConflictsHits.MatterConflictsHits should be the Primary key of
MatterConflicts ( think you said it was)
Add an index on MatterConflictHits.MatterConflicts this should speed up join
operations between the two tables.
Best of Luck.
