title: SQL Update using data from other tables and foreign keys
body: <p>I am trying to update a column from table1 based off of data from two other tables.</p>
  <ul>
  <li><p><code>Table 1</code> has columns <code>id, columnIWantToUpdate, table2FK, table3FK</code></p>
  </li>
  <li><p><code>Table 2</code> has columns <code>table2FK, table2_unique_id</code></p>
  </li>
  <li><p><code>Table 3</code> has columns <code>table3FK, table3_unique_id</code></p>
  </li>
  </ul>
  <p>So I get <code>table2_unique_id</code> and <code>table3_unique_id</code> as inputs and I want to use the columns table2FK and table3FK to update table 1 based off of the unique_ids I received as input</p>
