[SQL] Help writing a piece of SQL

[Nigel Bishop]

Hi, I would appreciate some help writing a piece of SQL   PG803   My table/data looks like this:        username     |            domain         |            sendto            +-------------+-------------------------------+------------------------------  Postmaster       | intthit08.uk.rabbit.com   | root  root             | intthit08.uk.rabbit.com   | [EMAIL PROTECTED]  stoat.griffin    | trusting.co.uk            | [EMAIL PROTECTED]  stoat.griffin    | trusting.com              | [EMAIL PROTECTED]  stoat.griffin    | rusty.co.uk               | [EMAIL PROTECTED]  stoat.griffin    | rusty.com                 | [EMAIL PROTECTED]  matilda.clematis | trusting.com              | [EMAIL PROTECTED]  matilda.clematis | trusting.co.uk            | [EMAIL PROTECTED]  matilda.clematis | rusty.co.uk               | [EMAIL PROTECTED]  matilda.clematis | rusty.com                 | [EMAIL PROTECTED]  *                | trusting.com              | [EMAIL PROTECTED]  *                | trusting.co.uk            | [EMAIL PROTECTED]  *                | rusty.co.uk               | [EMAIL PROTECTED]  *                | rusty.com                 | [EMAIL PROTECTED]  *                | windoze.com               | [EMAIL PROTECTED]  *                | windoze.co.uk             | [EMAIL PROTECTED]  admin            | windoze.co.uk             | [EMAIL PROTECTED]  admin            | windoze.com               | [EMAIL PROTECTED]  *                | saxon.co.uk               | [EMAIL PROTECTED]  *                | saxon.com                 | [EMAIL PROTECTED]     The query will have the username and domain passed in as variables.   If the username and domain exist then return the sendto   The bit I’m struggling with is if the username doesn’t exist then return the sendto where the domain exists   e.g.  username=fred (this doesn’t exist) and domain=rusty.com then return [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED]   Any help on this would very much appreciated; it’s been driving me mad for the last day.   Thanks     Nigel Communications on or through ioko's computer systems may be monitored or recorded to secure effective system operation and for other lawful purposes.
