title: Update table with joining another table
body: <p>I want to set field <code>f1</code> in table <code>t1</code> with the value <code>122</code> if field <code>f2</code> in table <code>t2</code> has value <code>134</code>. Suppose field <code>f34</code> is the key between table <code>t1</code> and <code>t2</code>.<br>
  How would I write the query for this in SQL Developer?</p>
