Question

I am working on a database join and I want to do the following:

Select tabel_one.id, 
       tabel_one.title, 
       tabel_one.content, 
       table_two.value as table_two.key 
  from tabel_one 
  Join table_two ON table_two.id = table_one.id ....

The Important part is:

table_two.value as table_two.key

Is there a way this could work?

Answer 1

No, you cannot define an alias referencing a table.

In general, you should simply use:

table_two.value as key

Otherwise, as OMG Ponies suggested in another answer, you can wrap the alias in backticks:

table_two.value as `table_two.key`
