title: SQL: Set default value to NULL for all columns without default value
body: <p>The webhosting I use has enabled StrictMode for the Databases. All my php scripts now stopped working because they report I haven't defined a default value for some columns.</p>
  
  <p>As I have a lot of columns in a lot of tables, is there a way to set all the columns with "default value = none" with "default value = NULL" ?
  In this way it won't report me the error anymore.</p>
  
  <p>Of course, If there's another (better) way, I am available for it.</p>
  
  <p>I tried looking on the net, but I couldn't find anything suitable for this case.</p>
