Bind variables problem, very urgent

Question

hi,
Oracle gurus,
In my current project while executing the following ststement i am getting the run time error"ORA-01008: not all variables bound".
This statement is used inside of a procedure and some bind arguments have values and some arguments have NULL values.

ur suggestions r most welcome

Answer 1

Placeholders (:name) are bound by position in EXECUTE IMMEDIATE SQL statement. Hence Oracle does not consider multiple :p_comp_id in your statement to be the same thing. You would need to repeatedly bind them for each occurrence, or use an approach (DBMS_SQL.BIND_VARIABLE or EXECUTE IMMEDIATE PL/SQL block) which binds by name or position / name.
In the case of the above example you would have a USING clause similar to the below (Note that I am unable to test this).
EXECUTE IMMEDIATE sql_statement
   USING p_comp_id, p_comp_id, p_site_id,
      p_site_id, p_task_type, p_comp_id,
      p_po_no, p_ebiz_sku_no, p_sku_status,
      p_lp, p_batch_no, p_comp_id;
