You can not do this if the IDTraining field is unique. The first 3 fields have to be the same value for each unique course. If that is not so, the query will fail. You will also have to not select the HELD field as this is probably not unique for each courseid. Otherwise, the following should work in Oracle.

select distinct(courseid), course, subject from training

Keep in mind Oracle is not as liberal with SQL syntax like VFP and, possibly SQL Server. If this is not what you are looking for, you will need to provide sample data.
