Insert data from a Dataset into a SQL Database

Hi guys my name is Ralph, i am kinda new to this so please bear with
me.
I have written a .net web service which accepts a stream of data
see relevent source code).

Public Function PutBondInfo(ByV al data As String) As DataSet
Try
Dim zh As New ZipHelper
Dim sz As String
Dim cn As SqlConnection
Dim da As SqlDataAdapter
Dim ds As New DataSet
Dim xSet As New DataSet
Dim sSql As String

Dim mySerializer As XmlSerializer = New
XmlSerializer(d s.GetType())

cn = New
SqlConnection(" server=HLSQL;ui d=test;pwd=;dat abase=test")
cn.Open()
da = New SqlDataAdapter( "SELECT * FROM BondStatus", cn)
'da.TableMappin gs.Add("BondSta tus", "NewDataSet ")

sz = zh.Decompress(d ata)
zh = Nothing

da.FillSchema(d s, SchemaType.Mapp ed, "BondStatus ")
'da.MissingSche maAction = MissingSchemaAc tion.AddWithKey
da.Fill(ds, "BondStatus ")

Dim st As New MemoryStream(En coding.UTF8.Get Bytes(sz))
' Create the object from the xml file
xSet = CType(mySeriali zer.Deserialize (st), DataSet)
xSet.Tables(0). TableName = ds.Tables(0).Ta bleName

ds.Merge(xSet, False, System.Data.Mis singSchemaActio n.Add)

'ds.AcceptChang es()

Dim SqlCB As SqlCommandBuild er = New SqlCommandBuild er(da)
da.Update(ds, "BondStatus ")

st.Close()
da.Dispose()
SqlCB.Dispose()
cn.Close()

Return ds
Catch ex As Exception
ex.Message().To String()
End Try

End Function

This data is compressed.I decompress the data and receive the xml
which is then
deserialized into a dataset. this part works great no problems. My
problem is then taking that dataset and pushing the data into a table
on my SQL server. The elements in the xml and the field names of my
SQL table 'BondStatus'
are exactly the same. The table names are different the xml has
'Table' as its table name and so on. As you can see from the code I
have tried table mappings, assigns, merges etc with no luck.

Ladies and gents if anyone has a clue as to what I am doing and can
help me, it would be appreciated.

Thanks in advance
Ralph

My goal is to get data from an XML file into a couple of tables in an Access database. The XML file is a little complex so I need control over what I do (I can't just read it into a dataset). The way I have it now is ennumerating through my XML file and for each record, running an INSERT INTO SQL statement to put the values in the database. Is this going to be okay with 50 or so records (hitting the database with 50 or so INSERT...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
