Hi,
I have some standard code below that seems to work fine with all databases I
have tested including teradata, oracle, sql server etc.
All I am trying to do is return a record set object to the data in a table.
I've just installed and tested it on postgres and it gives me an error -
'object or provider is not capable of performing requested operation'
can anyone give me any clues as to what I am missing?
The code below can be tested in excel if you add a reference to ADO.
Public Sub test()
'connect
Dim cnSim As New ADODB.Connection
Dim connectionstring As String
connectionstring = "Provider=PostgreSQL.1;Password=password;User
ID=postgres;Data Source=localhost;Location=postgres;Extended
Properties="""""
cnSim.connectionstring = connectionstring
cnSim.Open
'list the tables
Dim s As String
Dim s1 As String
Dim rs As New ADODB.Recordset
Set rs = cnSim.OpenSchema(adSchemaTables)
While Not rs.EOF
s = rs!Table_Schema & "." & rs!TABLE_NAME
s1 = rs!TABLE_NAME
Debug.Print s
rs.MoveNext
Wend
'works fine to here.
'try to return record set of a table
Dim aRestrictions As Variant
aRestrictions = Array(Empty, Empty, s, Empty)
'aRestrictions = Array(Empty, Empty, s1, Empty)
Set rs = cnSim.OpenSchema(adSchemaColumns, aRestrictions)
'Error - object or provider is not capable of performing requested
operation'
End Sub
