In DB2, you can use IS NULL to determine if a field is empty.
Here is an example query statement to check if a field named column_name is empty:

SELECT *
FROM table_name
WHERE column_name IS NULL;

If the query results return a record, it means the field is empty; if the query results are empty, it means the field is not empty.
