  user will click on a tab 'ABC','DEF'... and when they do i need to query for all last names that begin with A%, B%, C% or D%, E%, F% can i do this in one query or do i have to use 3 queries to retrieve all the rows that meet the criteria.

  You could use

  WHERE yourColumn LIKE 'A%' OR yourColumn LIKE 'B%' OR yourColumn LIKE 'C%'

  or just create a view with an additional column

  CASE WHEN yourColumn LIKE 'A%' OR yourColumn LIKE 'B%' OR yourColumn LIKE 'C%' THEN 1

  WHEN yourColumn LIKE 'D%' OR yourColumn LIKE 'E%' OR yourColumn LIKE 'F%' THEN 2

  ELSE 3 END AS Grp

  Then you could simply use WHERE Grp=1.

  Select LastName from MyTable

  Where LastName like '[A-C]%'

  Select LastName from MyTable

  Where LastName like '[D-F]%'

  or

  Select LastName from MyTable

  Where LastName like '[ABC]%'

  Select LastName from MyTable

  Where LastName like '[DEF]%'

  ...

  It would be good to have an index on LastName. Check execution plan and logical reads.

  Hope this helps.
