title: select statements in oracle with for read only
body: <p>I have a <strong>Database Links</strong> in <strong>Oracle</strong>, and when I query some data like: <code>select * from kfilwrk@something for read only</code>, I have an error: "missing keyword". I can just write select statement, but the problem is, I need to add <code>for read only</code> because my <code>select</code> statement may change some data.</p>
  
  <p><br>
  UPD: when I write simple select statement and retrieve data, after that I close SQL Developer, it asks me to rollback or commit data. It means the select cursor updates some data </p>
