FETCH Examples
1. Typical fetch, with associated cursor statements.
exec sql begin declare section;
    name character_string(20);
    age integer;
exec sql end declare section;

exec sql declare cursor1 cursor for
    select ename, age
    from employee
    order by ename;

...

exec sql open cursor1 for readonly;

loop until no more rows
    exec sql fetch cursor1
        into :name, :age;
    print name, age;
end loop;

exec sql close cursor1;
Assuming the structure:
Emprec
    name character_string(20),
    age integer;
the fetch in the above example can be written as:
exec sql fetch cursor1
    into :emprec;
The preprocessor interprets that statement as though it had been written:
exec sql fetch cursor1
    into :emprec.name, :emprec.age;
2. Fetch, using an indicator variable.
exec sql fetch cursor2 into :name,
 :salary:salary_ind;
