experts... This looks like a simple question. I have 2 tables with oid as the common key.
If I want to get the records from table a which have a match with table b plus the records from table a which does not have a match with table b, how do I query that?

for ex: table a has the records
oid       name    
1          aaa                    
2          bbb
3          ccc
4          ddd
5          eee

and table b has the columns

oid      name   value
1          aaa     101
2          bbb      102

I want the output like

oid           name          value
1              aaa            101
2              bbb             102
3              ccc          
4              ddd
5             eee
