Sorting an Array

9 posts in this topic

#1 ·  Posted (edited)

I am doing some work in an Access database using the ADO UDF. Using the function _accessQueryLike returns an array where the values are seperated by Chr(28). Ex:

$aHuntCSR = _accessQueryLike($sFilePath, $sWMTable, $sWGDN, $iCSR)
 _ArrayDisplay($aHuntCSR, "")

returns this:

[0]|11

[1]|6704108472

[2]|670402029

[3]|670412030

[4]|670422031

[5]|670432032

[6]|670442033

[7]|670467006

[8]|670472047

[9]|670487009

[10]|670497068

[11]|6704117012

I am having a time figuring a good way to sort by the second column (determing the largest value would also work for me). The one with 10,0,1,2,3 etc. Is there a way to sort this type of array like that? Many thanks for the help!

You could StringSplit Each of the array Elements Using Chr(28) Then Sort the resolting array. In the meantime I'll take a look at adding a sort parameter into the function. I'm sure that if I do that then the next request will be for sort on multiple colums so I might as well take that as a given right now.

I would probably change the function call by adding in $rSort = -1 so as not to break existing scripts. And I'll probably expect $rSort to be an array if it's not -1. That whole UDF has already been changed. My copy doesn't even use those function names any more and the name of the UDF has been changed. Expect an update in the next few days.

EDIT: Just had a second thought about this. In your case you are only using numbers so the problem is more one of leading 0's being dropped or not used at all. That I could quickly fix using StringLen and IsNumber but I still think the best way will be to do an actual sort, even then I may run into the same leading 0 issue.

For now What about

For $I = 1 To Ubound($Array) -1
   For $J = 0 To 9
      $sString = Chr(28) & $J & Chr(28)
      $rString = Chr(28) & "0" & $J & Chr(28)
      If StringInStr($Array[$I], $sString) Then $Array[$I] = StringReplace($Array[$I], $sString, $rString)
   Next
Next
_ArraySort($array, 0, 1)
This is untested but I think it's right. Edited by GEOSoft

Some version of this should work for that:

Global $iMaxIndex = 0, $iMaxVal = ""
For $n = 1 to $aHuntCSR[0]
    $avTemp = StringSplit($aHuntCSR[$n], Chr(28))
    If $avTemp[0] >= 2 Then
        If Number($avTemp[2]) > $iMaxVal Then 
            $iMaxIndex = $n
            $iMaxVal = $avTemp[2]
        EndIf
    EndIf
Next

If $iMaxIndex Then
    MsgBox(64, "Max Found", "The max value was " & $iMaxVal & ", found at index " & $iMaxIndex)
Else
    MsgBox(16, "Error", "Ivalid search results")
EndIf

It's just splitting each element of the array to test it.

:)

Edit: ... which GEOSoft already mentioned... Doh!

Thanks for the tip. I'll head down the StringSplit road and look forward to checking out the updates.

Hi,

Sorting arrays of strings is faster using my Subsort UDF, in Array2D in link from my signature; [but eliminate first row, and each line must have the same nmber of elements/ separators ("|")]

Best, Randall

_Array2D1DFieldSortSt(ByRef $arEither2D1D, $iIndex = "1"); 1D must be "|" delimited!

I think the problem of dropped or missing leading zeros will persist randall
