Hello,
I read documentation about fetch group but I dont really understand how does it work
I mean
I have DAO object describing tables
I want to get back a part of fiels of one of the table using dynamic fetchgroup
What are the steps to get back fields and to read them afterwards
Thank you for a short code description a little bit more clear than what I can read on official documentation
for exemple I can read the folwoing things
ReadAllQuery query = new ReadAllQuery(Employee.class);
FetchGroup group = new FetchGroup("nameAndSalary");
group.addAttribute("firstName");
group.addAttribute("lastName");
group.addAttribute("salary");
query. setFetchGroup(group);
which doesnt give any results to get back any information
if I have a table toto whith a toto.class DAO object and Field1 to Field5.
If i want to get back only Field2 and field4 what should I do ?
Thank you
