Hi EE:

  How can I iterate thru a SQL query resultset and perform some logic on it.

For example, I have a resultset like below

name1 name2
Bob Smith
Ann Smitherson

I would like to iterate thru each row and check if
1. Select count(*) from mytable where name1='Bob'
2. Select count(*) from mytable where name2='Smith'
3. Select count(*) from mytable where name1='Ann'
4. Select count(*) from mytable where name2 ='Simtherson'

if the count in any one is 0 then I need the name of that column to be returned in my resultset

I cant use temp tables
