Hi,

===
The Application IBEXPERT allows you to select a domain (DOM_CLIENT)
and by clicking on a certain tab (USED BY) it will display a list of
tables that the domain is used in (along with a the fields in each
table that uses it).

What I am wondering is:

Does anyone know of the SQL that will allow me to return the results
as above?
===

select *
from rdb$relation_fields
where rdb$field_source not like 'RDB$%'

System generated domains are starting with RDB$ - if you create
some yourself, they still will show up.

select rdb$relation_name, rdb$field_name
from rdb$relation_fields
where rdb$field_source = 'MYDOMAIN'
