CodeCop Warning AA0233

  • Artikkel

Use Get(), FindFirst() and FindLast() without Next() method.

Description

Avoid enumeration of a dataset when the dataset is not filtered.

Reason for the rule

If you use FindFirst(), FindLast(), or Get(), then the database query will only fetch a single record and must fetch again when you call Next(), which will lower performance.

Bad code example

codeunit 1 MyCodeunit
{
   var
      customer: Record Customer;
                
   procedure Foo()
   begin
      ...
      customer.FindFirst();
      ...
      customer.Next();
      ...
   end;
}

Good code example

codeunit 1 MyCodeunit
{
   var
      customer : Record Customer;
                
   procedure Foo()
   begin
      ...
      customer.FindFirst();
      ...
      end;
}
