title: Does MariaDB support nested transactions?
body: <p>Does MariaDB support <em>nested</em> transactions (not savepoints)?</p>
  
  <p>I want to be able to use nested transactions in stored procedures.  Currently in MySQL I am passing a parameter, "useTransaction" to each stored procedure, which controls if I start a new transaction in the body of that stored procedure.</p>
  
  <p>It would more more convenient if transactions could be nested <a href="http://docs.oracle.com/cd/E17076_02/html/gsg_txn/C/nestedtxn.html" rel="nofollow">like this</a>.</p>
