Could it be a problem with the connection string? I'm using: PostgreSQL 8.4.3 PostgreSQL-ODBC Driver 8.04.02 Microsoft ActiveX Data Objects Library 2.5 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=""""" connectionstring = "DSN=broersr; UID=broersr; Database=p2082849b" 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' While Not rs.EOF Debug.Print rs!COLUMN_NAME rs.MoveNext ' for some reason the recordset only return the xmin column for me before rs.eof = true Wend End Sub -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug
