Actually, the error message is misleading. There is nothing that I would
call ambiguous in your query: you have a syntax error. The join should be
written:
select pk from a inner join b on a.col1 = b.col2
Of course, you need to replace 'a.col1' and 'b.col2' with real column names
from tables a and b respectively.
