[dba-SQLServer] ADOX help

Can't you just submit an 'ALTER TABLE' statement rather than going
through ADOX?

Here's what I'm trying to do and can't -- I want to append a column to
an existing table, using ADOX. The code seems unnecessarily complex, and
it doesn't work. :( I don't get an error, it just doesn't work. The FOR
loop just runs through the Columns collection after the append, to see
if it worked. It really isn't part of the failing technique, because
that part works fine. The connection is fine.

'Append column to existing table
'using ADOX.
Dim cat As ADOX.Catalog
Dim tbl As ADOX.Table
Dim tblName As ADOX.Table
Dim col As ADOX.Column
Dim con As ADODB.Connection
Dim strConnection As String
con = New ADODB.Connection
strConnection = "Provider=SQLOLEDB.1;" & _ "Data Source=.\SQLEXPRESS;" &
_ "Initial Catalog = AdventureWorks;" & _ "Trusted_Connection=Yes"
Debug.Print(strConnection)
con.Open(strConnection)
cat = New ADOX.Catalog
cat.ActiveConnection = con
tblName = New ADOX.Table
tblName.Name = "Department"
'With tblName.Columns
' .Append("DepartmentHead", ADOX.DataTypeEnum.adChar) ' .Refresh() 'End
With col = New ADOX.Column With col .Name = "DepartmentHead"
.Type = ADOX.DataTypeEnum.adChar
.DefinedSize = 20
.Attributes = ADOX.ColumnAttributesEnum.adColNullable
End With
tblName.Columns.Append(col)
tblName.Columns.Refresh()
tblName.ParentCatalog = cat
For Each tbl In cat.Tables
If tbl.Type = "TABLE" Then
If tbl.Name = tblName.Name Then
For Each col In tbl.Columns
Debug.Print(col.Name)
Next
End If
End If
Next

It looks like the SQL Server Users and Groups collections aren't
supported for ADOX -- anyone know for sure -- I may have misunderstood
what I read.

Anybody here familiar with using ADOX and SQL Server and have some free
time today? I need help completing an article -- all I would need is a
few snippets of generic code -- but I need them today. Specifically, I'd
like an example of appending a column to an existing table or appending
a new table to a database. Also, I'd like a security example -- not as
specific on it -- could be as simple as appending a new user to an
existing group.
