Hello,

I am new to VBA.I need to create a connection to database{oracle} and excute query.
I have opened the vba editor in excel 2010.
I tried typing some code in it

Sub Macro1()
 
Dim cnn As New ADODB.Connection
Dim rs As New ADODB.Recordset
 
cnn.ConnectionString = "Driver={Microsoft ODBC for Oracle}; " & _
"Server=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourHost)(PORT=yourPort)))(CONNECT_DATA=(SERVICE_NAME=yourServicename)(SERVER=DEDICATED)));User Id=yourUser;Password=yourPwd;"
 
cnn.Open
Set rs = cnn.Execute("select count(*) cnt from my_table")
 
Debug.Print rs("cnt").Value
 
cnn.Close
 
End Sub

It fails at Dim cnn As New ADODB.Connection , saying user defiend type not found.

Please suggest how to proceed.

Hi,

I added the reference as mentioned, now I am getting another error -
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Hello,

I found another VBA code which listed down the installed drivers and I found the Oracle in OraDb10g_home1.
I have changed the driver to Oracle in OraDb10g_home1.
Now the error is ORA-12560 .

hello,

I check the Microsoft ODBC for Oracle message ->  this driver is not found.
Oracle in OraDb10g_home1 - message ->  Specified driver could not be loaded due to system error 998.

i also tried creating new DSN, then it gives same error as above.

I am thinking it is due to drivers not found or drivers not accessible.

Please suggest
do you have the Oracle clinet software installed on your PC?  It is a free download from Oracle.

AW
that should read CLIENT
