I'm trying to connect to an Oracle 10g database using the built in Microsoft ODBC for Oracle driver. I want to use an dnsless connection, so I grab my connection string from www.connectionstrings.com.
Ideally I won't have to setup a DNS entry or an Oracle TNS entry, and I may be mistaken, but I thought the above would do that for me. I'm getting the following:
ERROR [NA000] [Microsoft][ODBC driver for Oracle][Oracle]ORA-12514:
TNS:listener does not currently know of service requested in connect
descriptor
ERROR [IM006] [Microsoft][ODBC Driver Manager]
Driver's SQLSetConnectAttr failed
ERROR [01000] [Microsoft][ODBC Driver Manager]
The driver doesn't support the version of ODBC behavior that the
application requested (see SQLSetEnvAttr)."
As far as I can tell online, other people have used the Microsoft ODBC for Oracle driver to connect to 10g, but maybe I'm missing something. I'm connecting from a vb.net application by the way.
I'm not sure how kosher it is to answer your own question, but I found a connection string that is more what I'm looking for:
"Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _
"(HOST=myserver)(PORT=1521))" & _
"(CONNECT_DATA=(SERVICE_NAME=servicename))); " & _
"uid=username;pwd=password;
