Params:
sql – the SQL to execute. For example {call getEmpName (?, ?)}.
params – these are the parameters to fill the statement.
outputs – these are the outputs to fill the statement.
handler – the handler which is called once the operation completes. It will return a ResultSet.
Returns:
/**
   * Calls the given SQL <code>PROCEDURE</code> which returns the result from the procedure.
   *
   * The index of params and outputs are important for both arrays, for example when dealing with a prodecure that
   * takes the first 2 arguments as input values and the 3 arg as an output then the arrays should be like:
