                                JsonArray outputs)
```
    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"]
 
```
    Specified by:
    
    callWithParams in interface SQLOperations
    
    Parameters:
    
    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.
    
    Returns:
  - rxCallWithParams
