Thanks for your detailed answer. DB2-ExpressC doesn't seem to be
compliant, though.

I have this test table in DB2: lktBuildings(BUILDINGID, BuildCode)

Using MS Access SQL PassThrough, SQL statements are tunnelled through
ODBC without SQL parsing. If I send

SELECT "lktBuildings".BUILDINGID, "lktBuildings"."BuildCode"
FROM "lktBuildings";

it works fine, but if I send

SELECT "lktBuildings".BUILDINGID, "lktBuildings".BuildCode
FROM "lktBuildings";

(no quotes around BuildCode), I get the error

[IBM][CLI Driver][DB2/LINUXX8664] SQL0206N "lktBuildings.BUILDCODE" is
not valid in the context where it is used. SQLSTATE=42703 (#-206)

And the documentation states that "For a SELECT or DELETE statement, the
specified column is not a column of any of the tables or views
identified in a FROM clause in the statement."

I'll check the links you provided, thanks,
