Maybe just another WTF

[spl]

Having recently commented on addition to embedded arrays in another thread, I did bring out the possibility for those to replicate earlier MsdataShape Provider structures [built from scratch]. For updates:

• Microsoft has supposedly deprecated MsShape in favor of XML
• But [on at least my old Win10 laptop, it still exists in registry

Anyway... this works in PS and creates the output XML (even though the docs say it only should output to binary)

$file = "c:\temp\shape.xml"
If (test-path $file) {Remove-Item $file}
$conn = new-object -comObject ADODB.connection
$rs = new-Object -comObject ADODB.Recordset
$conn.Open("Provider=MSDataShape.1;Data Provider=NONE;")
$strShape = @"
SHAPE APPEND NEW adInteger AS CustID,
            NEW adChar(25) AS FirstName,
            NEW adChar(25) AS LastName,
            NEW adChar(12) AS SSN,
            NEW adChar(50) AS Address,
         ((SHAPE APPEND NEW adChar(80) AS VIN_NO,
                        NEW adInteger AS CustID,
                        NEW adChar(20) AS BodyColor,
                     ((SHAPE APPEND NEW adChar(80) AS VIN_NO,
                                    NEW adChar(20) AS Make,
                                    NEW adChar(20) AS Model,
                                    NEW adChar(4) AS Year)
                        AS VINS RELATE VIN_NO TO VIN_NO))
            AS Vehicles RELATE CustID TO CustID)
"@
$rs.Open($strShape, $conn, 1, 3, -1 )
$rs.Save($file,1)
$rs.Close()
$rs=$null
Exit


and fails in WB with similar syntax

My intention was to create a structure with MsDataShape that might be replicated with embedded arrays, but would appreciate the failure in WB for something simply done in PS.

[td]

I don't know but this works for me:

Code Select Expand

file = "c:\temp\shape.xml"
If FileExist(file) Then FileDelete(file)
conn = CreateObject("ADODB.Connection")
rs = CreateObject("ADODB.Recordset")
conn.Open("Provider=MSDataShape.1;Data Provider=NONE;")


[spl]

Yep, forgot the ( )... Now to get on with my intention.

[td]

Should mention that the multiple bracket syntax, i.e., mysa[0][0] does not work on safearrays. It is a bit of a knotty problem that will take so doing to figure out but it should work in the next release.

I'm sure all will be fine. ITMT:

• Hope viewers will see how easy it is to align PS<>WB for data processing
• Below I attached tested code from creating a shaped hierarchical recordset

I plan to play around with embedded arrays/maps to see if a structure can be created - i.e. where for an array of a customer there is a sub-array for payments [based on script] NOTE: should work with versions of WB prior to 2024.

... as it turns out shaped recordset can be persisted as xml. Rather than directly saving the shaped data to a file, which must be adtg binary format, you can save to an in-memory DOMDocument, then persist to file. The example below creates 2 CustId's with associated payments and displays results as xml keeping the parent-child relationship.
