Hello! I have a table with one field that is a varchar & primary key. Can the ? be added/updated/deleted to this varchar primary key? Thank you for your help. Sincerely, Tiffany __ Do You Yahoo!?

Re: ? in primary key
Hello,
It seems that the following preparedStatement is
changing the character ? to null.
PreparedStatement selectLocation =
conn.prepareStatement("select location, addressLine1,
addressLine2, addressLine3, addressLine4,
addressLine5, addressLine6, addressLine7,
addressLine8, addressLine9, addressLine10,
uniqueNumber from location WHERE region = "testing?"
order by location ASC");
ResultSet resultLocation =
selectLocation.executeQuery();
The region "testing" will become "testingnull" before
the preparedStatement is executed. How can I reform
this preparedStatement to work?
Thanks.
Sincerely,
Tiffany
