I am using spring jdbctemplate to interact with Oracle database. For fetching multiple rows for a given condition, I want to store the result in a csv file having Column names as the header.

I tried few ways -



In customizedrowmapper, I am fetching the rows from result set and setting the fields in Bean class. I could not find any easy way to convert from bean to csv file. As I dont have access to bean class code.

2nd way I found was to writer ResultSet directly to csv file like below using opencsv library.



This is working okay, but it is skipping one row while writing to csv. I tried few queries. Manually, I can see 4 rows in the result, but in the CSV, it stores only three rows. Anyone faced a similar issue?

Or any other way we can achieve the same, without manually getting each record from ResultSet and making it comma-separated string and storing in file.

Can you check if the first row of the ResultSet is not in the output? Maybe you called rs.next() once and the CSVWriter is calling rs.next() again thus skipping the first row?
