مبدأيا, طريقة الـ max(id) لازم تضيف ليها nvl عشان هيطلع no_data_found لو الجدول لسة فاضي. ثانيا: الطريقة دي غلط في الـ multi user environment. بالنسبة لأبكس, تقدر تعمل Process وتكتب فيها  If :Your_pk_item is null then select your_seq.nextval into :your_pk_item from dual; end if; نصيحة: ما تتعلمش بالطريقة دي, بالذات في الأداة دي. هتضيع عمرك ومش هتوصل لمستوى يحترم.  شوف كتاب كويس أو كورس كويس وذاكر ومارس وطبق الي ذاكرته عشان توصل لمستوى كويس. وفقك الله لما يحب ويرضى.

الف شكر كل عام وانتم بخير
