Connecting to a MS Access Database

Recommended Posts


What I want to do to me seems like it should be very simple, but I can't seem to find any good information on doing so. I've looked at some tutorials online, but I can't seem to find the basic information for actually connecting to a specific database and reading all the data from a specific table to an array. If that is to vague, this is what I'd like to learn how to do.

Open a specific MS Access database that is closed.

Pull all the information from a specific table into an array (a single record as an element)

Then close the database

I'll then use the array to do what I need. I don't need to do any database manipulation, I just need to read a single table from it. I even found an MSAccess.au3 file, but unfortunately it wasn't much help to me.

Any advice is greatly appreciated.

So I've kind of figured this out, but I'd like a little input if anyone is willing. Am I missing anything important? Should I include any kind of error checking. (The print function is just to test that the array gets populated correctly.)

Global $outputArrayRS [1][1]
Global $fieldCount
Global $recordCount

$tableName = "FormData"
$dataBase = "FormFill.mdb"
$query = "Select * From " & $tableName

ReadDBDataToArray($query, $dataBase)


Func ReadDBDataToArray($_sql, $_dbname)
    $adoCon = ObjCreate ("ADODB.Connection")
    $adoCon.Open ("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & $_dbname)
    $adoRs = ObjCreate ("ADODB.Recordset")
    $adoRs.CursorType = 1
    $adoRs.LockType = 3
    $adoRs.Open ($_sql, $adoCon)
    $fieldCount = $adoRs.Fields.Count
    $recordCount = $adoRs.RecordCount
    ReDim $outputArrayRS[$recordCount][$fieldCount]
    $outputArrayRS = $adoRs.GetRows()

; just a tiny function to test if array is populated correctly.
Func printOutput()
    For $x = 0 to $recordCount -1 Step 1
        For $y = 0 to $fieldCount - 1 Step 1
            MsgBox(0, "test", $outputArrayRS[$x][$y])

I tried to pass the array, but it doesn't seem to like the ReDim

; this script will read data from an access database

I know this is 372 years old... but just needed to say, this is legit and thanks for it.. UDF's I'd seen acted buggy as shit. I'd written an entire application for work based on a much simpler method. Until I realized that it was only pulling back the last row as the result.. Couldn't find documentation anywhere.. saved me from scrapping the whole project..
