What you're looking for is an inner join. Ben Forta's "Teach Yourself SQL in
10 Minutes" is a good intro to SQL.
SELECT *
FROM (
[table 1] INNER JOIN [table 2]
ON [table 1].pronunciation = [table 2].pronunciation
) INNER JOIN [table 3]
ON [table 1].meaning = [table 3].meaning
Generally speaking, each of your tables should use numeric, arbitrary
primary keys (such as autonumber fields).
BTW the "EQ" operator is CFML. When you write a query you are writing SQL,
not CFML. The SQL operator is "=".

Subject: On querying a TB with FK's
Hi all,
Quick question on queries: I have a "Table 1" with 2 foreign keys (FK) from
two other tables, something like this:
Table 1:
word PK
pronunciation FK
meaning FK
Table 2:
pronunciation PK
word FK
Table 3:
meaning PK
word FK
So, if I query Table 1, will I get the values of "pronunciation" and
"meaning" through the relation, or do I also have to query tables 2 and 3?
If this last case is true, would I have to query Table 1 first to get the
value of "word", and then use to query the other two tables, with a
statement like "Where Table2.word EQ Table1.word"?
I'm using CF 6 and MS Access 2000 (I know, I know, not the best DB, but
that's all I have right now).
Thanks :-)
