I believe I may need to use some inner / outter joins to accomplish this, but wanted to ask for some feedback.
I have 3 tables that I needing to pull some data out of. The primary key is Account_Num.
Table1 - Contains all the accounts that I need to pull a list from where tot_val > 750000
Table2 & Table3 - These contain various amounts of information for the accounts that I got from Table1. Some of the accounts from table1 may not contain values in table2 & table3. I need to pull the result set together, so I ultimately see something like:
account_num tot_val tax_amt owner_name owner_address num_rooms num_bathroom
Example of Tables:
--------------------------------------------
Table1 (T1)
account_num tot_val
---------------------------------------------
Table2 (T2)
account_num tax_amt owner_name owner_address
---------------------------------------------
Table3 (T3)
account_num num_rooms num_bathroom
---------------------------------------------
Thanks.

Yes, you are right you need outer joins.
Please read OraFAQ Forum Guide.
Generally speaking, for SQL question you need to:
- post a test case: create table and insert statements along with the result you want for these data
- post what you already tried
- post this in a formatted way, see "How to format your post?" section
- post your Oracle version (with 4 decimals)
Regards
Michel
