Hi Ketan,
This does not sound right.
could you please tell us which MonetDB version are you using, also could you give us the complete query, as well as the output of running the query prefixed with "explain" ?
Also can you tell us the schema of the table and if you have any constraints on it, such as primary key?
thank you,
lefteris
