Getting extracter 'N' in query string from weblogic server

Question

hai,
I am using weblogic7.0 as app server and mssql2000 as database server.
When writing sql queries i am using prepared statements.
Ex:
PreparedStatement pstmt=con.preparedStatement("select email from temp where tempid=?")
pstmt.setString(1,"0000A");
after executing the above query. If i check the query statement in database profiler
then i am getting the following stament:
select email from temp where tempid=N'0000A';
here i am getting an extra character 'N' in the query string.
Can anybody tell me how can i avoid that.
Thanks in advance

--durgaHi. The driver is putting that there to ensure that if your parameter is a
true-16-bit character that the DBMS doesn't corrupt it.
If your string data are guaranteed to be simple English 7-bit ASCII
characters, there's a driver property you can add to the pool connection
properties that will tell the driver not to put the "N'" prefix. This is
an important performance benefit because the "N'" will stop the DBMS from
using varchar indexes in searches.
If you are using the weblogic mssqlserver driver, add the useVarChars=true
property. If you are using the MS free driver or the DataDirect driver,
add a property sendStringParametersAsUnicode=false.
