[PHP-DB] Another PDO ?

[Jim Giner]

Reading up on the pdostatement class.  Wondering what the intent of the 
columnCount function is.  I mean, aren't the number of columns in a 
result known when you write the query?  Granted, you might have some 
very complex query that you may not know the number, but for most 
queries you will know the columns you are expecting.  So - what am I not 
seeing?
