Hello All,

 This might be simple question, but am not getting the SQL query right for
my problem.


For eg, consider following table

NonUniqueNo  Name
-----------------
23             A
23             B
24             C
25             A
23             E


How can I find the number of people for which an entry has been recorded in
my table?

The answer I am expecting is 4 ( i.e. A,B,C,E)

Using query "select count(DISTINCT Name) from TableA" results in an error.

Could anyone please post a SQL query for my problem?

Thanks in advance,

Bharath
