Global function to work with out all parameters

Is it possible to have a global function that works with out having all parameters defined? Right now I can't see a way, but I'm just diving into global functions.

I have a sports DB and there are many calculations that are similar so I'm finally trying out global functions.

I have a function that is pretty simple:

function teamAvP(tID : number,yNum : number) do
    avg((select Results)[TeamID = tID and Year_calc = yNum].Penalty4Average_Count)
end

I want to be able to use this function to find all results of a tID and sometimes use the yNum parameter. I have a few more parameters that I want to throw in, but this is a good start.

Thanks,

    It is not possible to set default parameters or omit a parameter when calling a function. Ninox expects the right number of parameters with the right type for each.

    But you can call a function with one (or more) parameters with a null value:

    teamAvP( this.id, number(void) );

    So, in your global function, you check if yNum is void or not. You have several ways to do this. Here are two examples :

    - create a test with two different processes : 

    function teamAvP2(tID : number,yNum : number) do
    if (ynum = void) then
        avg((select Results)[TeamID = tID].Penalty4Average_Count)
    else
        avg((select Results)[TeamID = tID and Year_calc = yNum].Penalty4Average_Count)
    end;
end

    - include your test in the where clause (yNum = void or Year_calc = yNum)  : 

    function teamAvP2(tID : number,yNum : number) do
    avg((select Results)[TeamID = tID and (yNum = void or Year_calc = yNum)].Penalty4Average_Count)
end;

    Ok, how does one do a null in a text field?

    I have this global function:

    function teamAvP(tID : number,yNum : number,cName : text,rType : text) do
    avg((select Results)[TeamID = tID and (yNum = void or Year_calc = yNum) and (cName = void or 'City Name' = cName) and (rType = void or 'Round Type' = rType)].Penalty4Average_Count)
end;

    I want to leave rType, the 4th parameter, empty. So I've tried:

    let xY := record(Seasons,number(Season));
teamAvP(Team.TeamID, xY.Year, City.'City Name', "")

    All other parameters are based on field selections either from dynamic choice or reference field. the rType is the only one that is hand coded.

    I've tried:

    ""

    text(void)

    text(null)

    None of the above work. What are my other options?

      Fred I just saw that you have to put text(void) : 

      function teamAvP(tID : number,yNum : number,cName : text,rType : text) do
    avg((select Results)[TeamID = tID and
        (yNum = void or Year_calc = yNum) and
        (cName = text(void) or 'City Name' = cName) and
        (rType = text(void) or 'Round Type' = rType)].Penalty4Average_Count)
end;

      Yes, sorry for letting the code run long.

      What else should I put if not text(void). It works for cName just not rType.

      Fred I'm not sure what's wrong? The function call with text(void) or the filter?
      Can you tell me more so I know where to look? Or send me an example?

      Fred You can also use the cascade call with different parameters:

      function GlobalJS(Gjs : text) do
    #{:text return Gjs}#
end;
function selectA(title : text) do
    select Customer where Title like title
end;
function selectAB(title : text,firstName : text) do
    selectA(title)['First Name' like firstName]
end;
function selectABC(title : text,firstName : text,lastName : text) do
    selectAB(title, firstName)['Last Name' like lastName]
end

       

      And you call the one you need:

      selectAB("Mrs", "L" ).---{'First Name'} {'Last Name'}---

      result : 
      Lisa Wilson
      Evelyn Thomas
      Natalie Marcus
       

      selectABC("Mrs", "L", "o" ).---{'First Name'} {'Last Name'}---

      result : 

      Lisa Wilson
      Evelyn Thomas

      Fred Does it work when you call teamAvP with void in the cName parameter?

     Ok, so I have this global function:

    function teamAvP(tID : number,yNum : number,cName : text,rType : text) do
    avg((select Results)[TeamID = tID and
                        (yNum = void or Year_calc = yNum) and
                        (cName = void or 'City Name' = cName) and
                        (rType = void or 'Round Type' = rType)].Penalty4Average_Count)
end;

    When I try any of the following for the 4th parameter I get an empty field:

    let xY := record(Seasons,number(Season));
teamAvP(Team.TeamID, xY.Year, City.'City Name', "")
or
teamAvP(Team.TeamID, xY.Year, City.'City Name', text(void))
or
teamAvP(Team.TeamID, xY.Year, City.'City Name', text(null))

    If I put in a value I get results:

    let xY := record(Seasons,number(Season));
teamAvP(Team.TeamID, xY.Year, City.'City Name', "1")

    All other parameters are based on field selections either from dynamic choice or reference field. the 4th parameter (rType) is the only one that is hand coded.

      Fred Like I said here you must to specify the type of void like this : (rType = text(void) or 'Round Type' = rType). With out it, Ninox try to found record with 'Round Type' = void.

     cName doesn't work if I hard code text(void), but since the data comes from a reference field it seems to work fine without the cName = text(void).

    I'm sorry, my eyes glazed over the rType = text(void) changes you made. That was the solution staring me in the face. Thanks for being patient with me.

      Fred You are so patient with others, I think it is the least I can do. Thank you for the help you bring to this forum 🙏.

      It work right now ?
