BD Lookup Error _ Not using the COmmunication channel!

Question

Dear all,
I Tried to  do DB Lookup as told in this blog by siva
/people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
I used the below code.
I am not Getting any error, the mapping is successfully ACTIVATED. But in the Receiver field i am Getting Null as output , the DB lookup which i have mentioned is not connecting to the Database and executing and fetching the query. Just inthe receiver field its througing the Null valuse. The Required Value is not fetched by using the communication channel.
I am getting the above error when i try to TEST THE MAPPING in IR.
Below is the code i used.
SERVER:XI 3.0
SP:18
RECEIVER DATABSE: MSQL SERVER 2000
CODE----
//write your code here
String Query = "";
Channel channel = null;
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
Query = "Select cir_id from circle where cir_sap = 'IDBL'";
try{
channel = LookupService.getChannel("<Business Service/System Name>","JDBC_channel_receiver Communication channel");
accessor = LookupService.getDataBaseAccessor(channel);
resultSet = accessor.execute(Query);
for(Iterator rows = resultSet.getRows();rows.hasNext();){
Map rowMap = (Map)rows.next();
result.addValue((String)rowMap.get("cir_id"));
catch(Exception ex){
result.addValue(ex.getMessage());
finally{
try{
if (accessor!= null) accessor.close();
catch(Exception ex){
result.addValue(ex.getMessage());
END CODE----
Please help me out.
I am getting output as null. But in database value is there for cir_id where cir_sap='IDBL'.

As i told before i have tested the interface, its not showing any error, its Activated and throwing Null as output.
Its not fetching the value from database. In CC Monitoring also the adapter is in Green Status. No error over there. Its throwing the output as Null (Default value in the code.)
Below is the connection parameter i have used:
DRIVER:com.microsoft.jdbc.sqlserver.SQLServerDriver
CONNECTION : jdbc:microsoft:sqlserver://<IP>:1433;DatabaseName=test_db
But in the blog
/people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
If u can see properly, he has mentioed some extra parameters in the JDBC Connection Parameters.
But the screenshot is not proper so i am not able to see the querry he has used in Connection parameters.
Please help
Could anyone tell how to write the Select statement in Connection Parameter for Adapter as given (Partialy in screenshot in BLOG)?
Regards,
Prakash
