Excel query to Oracle Database

TerryChen

Dear all:

I want to use Excel link to Oracle Database to query data, and I don't want to install the Oracle Client and through ODBC. Can some one tell me how to do?

Yes, you can use OLE DB...

Dear Satishbabu:
Thank you for your reply. And I don't want to use the ODBC to link between Excel and Oracle. Is there another method to do ? Thank you!

Terry,

I think I'm trying to do the same thing you are and that is not use ODBC/DSN. I think the solution is to use ADO. Here are some links that I found useful.

Here is some code I'm using:

Sub Main()
Dim Conn As New ADODB.Connection
Dim RS As New ADODB.Recordset
Dim Cmd As New ADODB.Command
Dim sqlText As String
Dim Row As Long
Dim Findex As Long
Dim Data As Worksheet
Dim X As Long
Dim UID As String
Dim PWD As String
Dim Server As String
Application.Calculation = xlCalculationManual
UID = "USERID" 'Enter the User ID
PWD = "PASSWRD" 'Enter the password
Server = "SERVER" 'This comes from your TNSNames.ora file
Set Data = Sheets("Sheet1") 'Change this to the name of the sheet you want to return data to
Data.Select
Range("A:F").ClearContents 'Change A:F to the range you expect data to return to
Conn.Open "PROVIDER=MSDAORA.Oracle;DATA SOURCE=" & Server & ";" & "USER ID=" & UID & ";PASSWORD=" & PWD 'Note, I am using MSDAORA as I use an ORACLE DB, you will need to change it for what DB you are using
Cmd.ActiveConnection = Conn
Cmd.CommandType = adCmdText
' Put your query next
sqlText = " select B.CSE_ID AS ORIGINAL_ID, M.CSE_ID AS REF_CASE_ID, M.PGM_ID AS REF_PGM_CODE, " & _
" RPT.TEXT AS REF_PGM_DESC, PAT.PTNT_FNAME AS FIRST_NAME, PAT.PTNT_LNAME AS LAST_NAME, " & _
" FROM OPTUSER.DD_BOEHEALTH2 b LEFT JOIN SUMM_CCS.MEMBER_REF M ON B.CSE_ID=M.CSE_ID "

Cmd.CommandText = sqlText
Set RS = Cmd.Execute
For X = 0 To 17 'Change to the number of columns you are selecting MINUS 1. this loops through the column names
' in the query and puts them in the spreadsheet
Data.Cells(1, X + 1) = RS.Fields(X).Name
Next
Do While Not RS.EOF 'this loops through the data and puts it in the spreadsheet
Row = Row + 1
For Findex = 0 To RS.Fields.Count - 1
Data.Cells(Row + 1, Findex + 1) = RS.Fields(Findex).Value
Next Findex
RS.MoveNext
Loop
Application.Calculation = xlCalculationAutomatic
Application.Calculate
End Sub

Hope that helps,
