title: SQL: convert all columns to VarChar(255)
body: <p>After some searching here on stackoverflow and on the web, I couldn't find the answer to my question. I'm not a real SQL talent, but I'm trying to covert all the columns in my table to varchar (255). It has about 600 columns which are all varchar, but the size limit varies. I would like them all to be 255. Is there a way to not having to do this manually? I work with MySQL.  </p>
  
  <p>Thanks!</p>
