Use CopyFromRecordset With ODBC Recordsets

Use CopyFromRecordset With ODBC Recordsets

You can create an ODBCDirect recordset for use with the Excel Range objects CopyFromRecordset method by using the DAO.Connection objects OpenRecordset method:

Public Function CreateDaoRecordset( _	ByVal sDataSource As String, _	ByVal sUser As String, _	ByVal sPwd As String, _	ByVal sSql As String) _	As DAO.Recordset	Dim daoWs As Workspace	Dim daoConn As DAO.Connection	Dim sConn As String	Dim dbEng As DBEngine	Set dbEng = New DBEngine	Set daoWs = dbEng.CreateWorkspace("", "admin", _		"", dbUseODBC)	sConn = "ODBC;DSN=" & sDataSource & ";UID=" _		& sUser & ";PWD=" & sPwd	Set daoConn = daoWs.OpenConnection("", , , sConn)	Set CreateDaoRecordset = _		daoConn.OpenRecordset(sSql, dbOpenSnapshot)End Function

The CopyFromRecordset method also works with Oracle8 databases. The trick: You must use a proper ODBC driver. The Microsoft ODBC driver for Oracle, msorcl32.dll version 02.573.3513.0, doesnt support the NUMBER data type in this method. The Oracle ODBC driver, sqora32.dll version, treats the NUMBER(n) data type as a dbDecimal and generates Unspecified Automation Error in the CopyFromRecordset method. But it accepts the NUMBER data type (without precision), interpreting it as a dbDouble.

CopyFromRecordset doesnt copy column names to the Excel worksheet for further data analysis or reporting, so use this simple code instead. It copies column names to the first row of the active Excel worksheet oWsh and copies all data from the daoRs Recordset. The code assumes oWsh and daoRs have been declared and initialized elsewhere:

oWsh.Activate	For iCol = 0 To daoRs.Fields.Count - 1		oWsh.Cells(1, iCol + 1).Value = _		daoRs.Fields(iCol).Name Next	oWsh.Range("A2").CopyFromRecordset daoRs
