I'm not following you. I have two tables each with a column, state_code char(2) NOT NULL.
That is a char(2) column for which ‘??’ is a valid value. The fact that it is named state_code is immaterial; the domain that you created doesn’t get used. There is no magic linking just by virtue of using the same name. Change char(2) to state_code if you wish to apply the domain on the column.
David, I think I'm now on your page. In the schema I change the column data type to state_code, then I add the SQL code creating the domain at the top of the .sql file. Yes? Thanks, Rich
