Yes.

Well,

I think after cursor build you have 2 safe checks:

    curs <> nil
Or 
    db.ErrNumber


You can write for example:

    if curs <> nil and curs.FirstRecord
        do
            ...
        while curs.NextRecord
    endif


Or 

    for I = 1 to curs.GetRecordCount()
        .....
    
        curs.NextRecord()

    next
