  Re: What are the steps you will take to improve performance of a poor performing query?
Answer
# 1
No indexes, table scans, missing or out of date statistics, 
blocking, excess recompilations of stored procedures, 
procedures and triggers without SET NOCOUNT ON, poorly 
written query with unnecessarily complicated joins, too 
much normalization, excess usage of cursors and temporary 
tables.


Some of the tools/ways that help you troubleshooting 
performance problems are: SET SHOWPLAN_ALL ON, SET 
SHOWPLAN_TEXT ON, SET STATISTICS IO ON, SQL Server 
Profiler, Windows NT /2000 Performance monitor, Graphical 
execution plan in Query Analyzer.
