Question about clustering multiple columns

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
 
I have a database where there are three columns (name,date,data).  The queries are almost always something like SELECT date,data FROM table WHERE name=blah AND date > 1/1/2005 AND date < 1/1/2006;.  I currently have three B-tree indexes, one for each of the columns.  Is clustering on date index going to be what I want, or do I need a index that contains both name and date?
