Question

I have a database with several tables, one being used to reference others :

Main table :

MAIN | table1 | table2 | table3
        int   |  int   |  int

Each line of this table corresponds to a product, and contains the oid of a line in a daughter table

Then I have my daughter tables :

TABLE1 | name | adress | phone
       | text | text   | ...

My question is quite simple, even though as I just start using databases I can’t get to find the answer.

I would like to get the oid(s) of the line(s) of the main table which references the line of table1 for which name is equals to “bob”.

Something like :

SELECT * from main where table1.name = "bob"

If no complete solution, could you point me to some documentation ?
I think I miss vocabulary to find proper ressurces to do that.

Thanks by advance

Answer 1

You mean like SELECT oid FROM MAIN WHERE table1 IN (SELECT oid FROM TABLE1 WHERE name = 'bob')?

table1 == foreign key from MAIN to TABLE1.
