Reviews April 12, 2001 - 8am Central time zone Bookmark | Bottom | Top Reviewer: gaurang useful summary of connect by September 25, 2002 - 2pm Central time zone Bookmark | Bottom | Top Reviewer: RParr from Seattle, WA U.S.A. in a fraction of the space you provided a much better overview of connect by and basic heirarchical query. Nice overview January 22, 2003 - 1am Central time zone Bookmark | Bottom | Top Reviewer: Anirudh from New delhi, India Hi Tom Your explaination about the connect by clause was very helpfull. However, I have a question we have got a function FUNCTION Get_Parent_Entity_Id ( in_test_pgm_id number, in_test_admin_id number, ic_child_entity_type_code varchar2, in_child_entity_id number, ic_parent_entity_type_code varchar2 ) RETURN number IS ln_count NUMBER; BEGIN ln_count := 0; BEGIN select n_parent_entity_id into ln_count from ( select n_test_pgm_id, n_test_admin_id, c_parent_entity_type_code, n_parent_entity_id from rpt_entity_struc res start with res.n_test_pgm_id = in_test_pgm_id and res.n_test_admin_id = in_test_admin_id and res.n_entity_struc_id = 0 and res.c_child_entity_type_code = ic_child_entity_type_code and res.n_child_entity_id = in_child_entity_id connect by res.n_test_pgm_id = prior n_test_pgm_id and res.n_test_admin_id = prior n_test_admin_id and res.n_entity_struc_id = prior n_entity_struc_id and
es.c_child_entity_type_code = prior c_parent_entity_type_code and res.n_child_entity_id = prior n_parent_entity_id ) where c_parent_entity_type_code = ic_parent_entity_type_code; EXCEPTION WHEN NO_DATA_FOUND THEN ln_count := 0; WHEN OTHERS THEN ln_err_num := SQLCODE; lc_err_msg := 'Error in Get_Parent_Entity_Id - ' || substr(sqlerrm, 1, 200); raise_application_error(-20000, lc_err_msg); END; RETURN ln_count; -- Algo:n_parent_entity_id is retrieved based on the input parameters passed besides the ic_parent_entity_type_code which is one of the important input columns to be considered. The Hierarchical query (STARTWITH and CONNECT BY) clauses are used to find the root parent id. Question The connect by prior clause here refers to the columns and one of those (n_entity_struc_id ) is not in the select list. My question is what is the use of that PRIORing the column when it has not been selected.? Followup January 22, 2003 - 8am Central time zone: the same as when you use it in a predicate, no different. select ename from emp where empno = :x what is the use of empno in the predicate if it has not been selected? well, it is used to identify what record(s) you want. same with columns in the start with, connect by prior and so on...
