Good Day Folks,

I'm trying the Oracle Data Provider, the one written by
Microsoft, without success thus far.

The code and error message are listed below.

Any ideas ?
Thanks in advance.

Hi

Add this line of code to
SET TRANSACTION READ ONLY;
before the SELECT statement and add
COMMIT;
after the SELECT statement.

And also check out the following link
