Simple Question on SQL.

Question

I have three tables. Two entity tables and one relation table.
Table A(AKey, priority, field3, field4)
Table B(BKey, field5, field6)
Table C(AKey, priority, BKey)
The fields AKey and priority form the primary key for the Table A and the field BKey forms the primary key for table B. The table C is a relation table that links records from Table A and Table B. The relationship is one(record from Table A) to many(record from Table B).
Table A :
Akey priority field3 field4
A1 1 23 456
A1 2 45 789
A2 1 90 999
Table B :
Bkey field5 field6
B1 abchost 8909
B2 defhost 7909
B3 ghihost 9090
B4 hijkost 7867
B5 kost 7868
B6 kost 7869
Table C:
Akey priority Bkey
A1 1 B1
A1 1 B2
A1 2 B3
A2 1 B4
A2 1 B5
A2 1 B6
I want to generate the following data from the above tables :
Akey priority BKey field3 field4 field5 field6
A1 1 B1 23 456 abchost 8909
A1 1 B2 23 456 defhost 7909
A1 2 B3 45 789 ghihost 9090
A2 1 B4 90 999 hijkost 7867
A2 1 B5 90 999 kost 7868
A2 1 B6 90 999 kost 7869
How can I get the above data from the tables in an efficient manner?
Is it possible to generate the above data using SQL only ?
Thank You,

Answer 1

How about visiting an SQL course before using it?
select c.akey, c.priority, c.bkey, a.field3, a.field4, b.field5, b.field6
from a,b,c
where c.akey = a.akey
and c.priority = a.priority
and c.bkey = b.bkey
order by 1,2,3;
