title: SQL Alchemy: How to bulk update values from a list of dicts
body: <p>I would like to update a table 'Salary' which has fields:</p>
  
  <pre><code>employeeId,
  Salary
  </code></pre>
  
  <p>Now, I have updated values for each employee in a python dictionary, something like:</p>
  
  <pre><code>[
  {employeeId:1,Salary:10000},
  {employeeId:2,Salary:15000}
  ]
  </code></pre>
  
  <p>I am wondering if there is a way to do this update in a single SQL Alchemy update query rather than executing many update statements one by one</p>
