Oracle rename columns from select automatically?

Question

I have 2 tables with the following fields.

Table1

• AA
• BB
• CC
• DD

Table2

• AA
• CC

Answer 1

Try this

 select t1.AA "t1_AA", t2.AA "t2.AA"
 from table1 t1,
 inner join table2 t2
 on table1.DD = table2.EE

As he said before, you need to do it per column
