MySQL Error: #1052 - Column 'id' in field list is ambiguous

I get this when I post the SQL into phpMyAdmin. I guess I don't really know what the word ambiguous means. Can anyone tell me what is the problem?

SELECT id, title
FROM td AS a
INNER JOIN post AS cc ON cc.id = a.id
WHERE a.plt IN('79');

SQLZOO, Error 1052 Column 'name' in field list is ambiguous

This will maybe help you out.

It means that ID and/or Title exist in both tables - which one do you want to select? Rewrite it like so in order to fix the problem:

SELECT a.id, cc.title
      FROM td AS a
      INNER JOIN post AS cc ON cc.id = a.id
      WHERE a.plt IN('79');
