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 | is-unix@rabbit.com
stoat.griffin | trusting.co.uk | stoat.griffin@rabbit.com
stoat.griffin | trusting.com | stoat.griffin@rabbit.com
stoat.griffin | rusty.co.uk | stoat.griffin@rabbit.com
stoat.griffin | rusty.com | stoat.griffin@rabbit.com
matilda.clematis | trusting.com | matilda.clematis@rabbit.com
matilda.clematis | trusting.co.uk | matilda.clematis@rabbit.com
matilda.clematis | rusty.co.uk | matilda.clematis@rabbit.com
matilda.clematis | rusty.com | matilda.clematis@rabbit.com
* | trusting.com | rusty@rabbit.com
* | trusting.co.uk | rusty@rabbit.com
* | rusty.co.uk | rusty@rabbit.com
* | rusty.com | rusty@rabbit.com
* | windoze.com | windoze@badger.com
* | windoze.co.uk | windoze@badger.com
admin | windoze.co.uk | matilda.clematis@rabbit.com
admin | windoze.com | matilda.clematis@rabbit.com
* | saxon.co.uk | superR@uk.diamond.com
* | saxon.com | superR@uk.diamond.com
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 rusty@rabbit.com, matilda.clematis@rabbit.com, stoat.griffin@rabbit.com
Any help on this would very much appreciated; it’s been driving me mad for the last day.
Thanks
Nigel
