title: DB Browser for SQLite - Constraints tab
body: <p>Can't see the point of the &quot;Constraints&quot; tab in the &quot;Edit table definition&quot; window of DB Browser for SQLite.</p>

  <p>I can name the constraint but the &quot;Columns&quot; field and the &quot;SQL&quot; field remain stubbornly un-editable. I can edit CHECK in the &quot;Fields&quot; tab but can't add a named CONSTRAINT in that tab.</p>
  <p>Question: What is the &quot;Constraint&quot; tab for? Can I use it to name a constraint <strong>and</strong> edit the associated CHECK()?</p>
