title: MySQL - How to increase varchar size of an existing column in a database without breaking existing data?
body: <p>I have a column that is currently <code>varchar(100)</code> and I want to make it <code>10000</code>.</p>
  
  <p>is it as simple as </p>
  
  <pre><code>alter table table_name set column col_name varchar (10000);
  </code></pre>
  
  <p>I am afraid to corrupt the exiting data. Will I be ok if I run this query? Or should I do I <code>alter</code> the column another way?</p>
  
  <p>Thanks!</p>
