If a column is associated with an explicit table name, the table is searched for the column name. Based on the result of the search, one of the following occurs:

IF this … IS … THEN …
a matching column found in the table the requested information is returned.
not found in the table the NAMED list is searched for the column name.

“Named” names are not valid when used to fully qualify a table name.

a column name not found in the explicit table name or in the NAMED list a nonexistent column error is reported.
