Hi,
I am able to insert the null field using \N in the text file,but while retiving
the data I am not able to retrive it.
After inserting data I tried this select statement
select * from os_customer_master where updated_by=' ';
and
select * from os_customer_master where updated_by=null;
but it gives 0 rows.then how will I select this values.
