title: Debug SQL queries in SQuirrel-sql
body: <p>How do I go about debugging a SQL statement in SQuirrel-sql?</p>
  
  <p>I keep getting "unhelpful" errors like:</p>
  
  <blockquote>
  <pre><code>Error: [SQL0104] Token , was not valid. Valid tokens: ) OR.
  SQLState:  42601
  ErrorCode: -104
  </code></pre>
  </blockquote>
  
  <p>I would love to be able to see the line number where I made the error, or some other way of guiding me to where the problem is.</p>
  
  <p>I am working with the JDBC driver on a IBMi DB2 database.</p>
