How to debug DIH with MySQL?

[Walter Underwood]

I see a missing required "title" field for every document when I'm using DIH. 
Yes, these documents have titles in the database. Is there a way to see what 
exact queries are sent to MySQL or received by MySQL?

Here is a relevant chunk of the dataConfig:

    <entity name="book" query="select * from biblio where id &lt; 10000">
      <field name="id" column="id" />
      <field name="isbn" column="isbn" />
      <field name="isbn" column="ean" />
      
      <entity name="biblio_title"  
              query="select title from biblio_title where 
biblio_id='${biblio.id}'">
        <field name="title" column="title" />
      </entity>
