6.  def call(sql: String, handler: Handler[AsyncResult[ResultSet]]): SQLClient

   Calls the given SQL `PROCEDURE` which returns the result from the procedure.

   Calls the given SQL `PROCEDURE` which returns the result from the procedure.

   sql

     the SQL to execute. For example `{call getEmpName``.

   handler

8.  def callWithParams(sql: String, params: JsonArray, outputs: JsonArray, handler: Handler[AsyncResult[ResultSet]]): SQLClient

   Calls the given SQL `PROCEDURE` which returns the result from the procedure.

   Calls the given SQL `PROCEDURE` 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:

         params = [VALUE1, VALUE2, null]
         outputs = [null, null, "VARCHAR"]

   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
