You could do a stored procedure for inserting into another table... Otherwise if
you want to get the result as a query, you could do something like,
Select field1, exp(field2) as expoffield2 from tablename1

Hope that helps,

Hi all,

Thanks for replying to previous mail, I have one more question. Can I write a
postgresql query that retrieves a particular field from a table and performs
some mathematical calculation on that field involving exponential( exp) and pow
functions and storing the result in a new table.

Somethign like this
select field1 from tablename1 ( performing calculation on field1 ) ( storing in
another table)

Thanks and regards,
