I have data in a table which don't have parent child relation ship. Can I display the data in that table in hierarchical tree item in a form.
Is it a must that data should have parent child relationship to display them in hierarchical tree item in a form.
Just wanted to pose a question Can a (Unique and Not nullable)Alternate key of the parent table be part of child Table in an Identifying relationship i.e part of primary key of a child table????
Is there a rule that a primary keys of a parent table can be used to build a identifying relationship with its child?
I have a table called FAMILY which holda the data like , for father_gen_1 --->father_gen_2 --> father_gen_3 -- son.
father_gen_1 father_gen_2 father_gen_3 son
ABC XYZ GEF MNC
ABC lmn kth
I want to get the output which is a three column heirarical table and holds the parent child relationship Like following:-
id name parent_id
1 ABC NULL
2 XYZ 1
3 GEF 2
4 MNC 3
5 LMN 1
6 KTH 5
I have a DB that has one parent table with many child tables. I would like to delete all records(child - parent) based upon a particular "net_id". I have three versions that "seem" to work BUT I'd like to use "version2" because I want to go to the parent one time(for the parent delete I just made it simple for me) only and be able to delete the child record(s) from the child table(s). I want to achieve this w/o using triggers...
My question: Is version2 an "ok" way to delete child records or should I try another method(version1 or 3)??
create table PARENT
(
event_id NUMBER,
event_title VARCHAR2(50),
net_id VARCHAR2(16)
);
--truncate table parent;
insert into parent
(event_id, event_title, net_id)
values
(1, 'title1', 'CURLY');

I have a table which uses parent-child relationship to store the options available. I need a procedure to give me the full path given the id of a particular option.
I have two different functions. One of them uses the Oracle built in function and the other uses simple queries with a loop.The code of the functions are given below.
Now, the problem is with their "performance". The difference in their performance is significant. The function using the Oracle function takes more than 2 hours to run a query whereas the other function takes less than 2 minutes.
I am having trouble trusting the other function. No matter how many tests I perform on the output of both the functions, it always comes out to be the same.
Function 1
=====================
FUNCTION Gettree (opt_id IN NUMBER,i_app_id IN NUMBER)
RETURN VARCHAR2
IS
path VARCHAR2(32767);
application_no NUMBER;

I am working on a project, the insert statement is not functioning properly and I cannot find the error The error is in the insert statement for CustOrder. The error states that NULL cannot be inserted into CustOrder.CustID. I have declared CustID and its reference. I have looked over the code several times and I cannot find the problem.
If it makes a difference I am using APEX. The company has not database or program to work with a database so I am building everything from scratch.
declare
l_CustOrderID number;
l_CustID number := :P11_CustID;

There is table:
Column A | Column B |
X | X |
X | Y |
Y | X |
Y | Y |
I have selected view with "group by rollup":
ID | Column A | Column B |
1 | | |
2 | X | |
3 | Y | |
4 | X | X |
5 | X | Y |
6 | Y | X |
7 | Y | Y |
Now I want to display it in client app like a tree.So, I need create ID's of parents in child rows, like this:
ID | Parent ID | Column A | Column B |
1 | | | |
2 | 1 | X | |
3 | 1 | Y | |
4 | 2 | X | X |
5 | 2 | X | Y |
6 | 3 | Y | X |
7 | 3 | Y | Y |
We have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,
Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z
Requirement :
From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this
-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z
Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.
SQL Statements to create hierarchy table:
create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');
Approached already tried :
1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;
2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);
Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.
I have a parent table EMPLOYEE which includes columns (sysid, serviceno,employeename...) sysid is Primary key, serviceno is Unique key and I have child table DEPENDENT includes columns (sysid,employee_sysid,name,dob...) here again SYSID is primary key for DEPENDENTS table, employee_sysid is Foreign key of EMPLOYEE table.
Now I want to change SYSID (using sequence) in EMPLOYEE table which need to be update in DEPENDENTS table as well
Note: I have 10000 records in EMPLOYEE table as well as I have 5 more child tables which need to update new SYSID.

View 11 Replies View RelatedI've the following data and i need the parent and leaf most child,including their id's
Create table par_chld (id,p_id,c_id) as
(select 1,900,501 from dual union all
select 2,900,502 from dual union all
select 3,900,503 from dual union all
select 4,100,900 from dual union all

select 10,201,600 from dual union all
select 11,201,601 from dual union all
select 12,201,602 from dual )
In the above data
p_id =100 has c_id 900 , and this 900 acts as a parent which has child 501 , 502 ,503
And the output should be in the following format , Where i don't need the middle level data. I need parent and its leaf child along with the id's of parent and child
Expected output
id_p p_id id_c c_id

I tried the following query where i got the p_id,id_c,c_id columns , but unable to get the column id_p
select connect_by_root p_id p_id ,id id_c,c_id
from par_chld
where connect_by_isleaf =1
start with p_id not in (select c_id
from par_chld
where c_id is not null)
connect by nocycle p_id =prior c_id
getting the id_p column as expected above.
way to achieve the below logic.
SQL to pick up parent child relationship within same table with a certain logic.
Example:
mod_product_numberProduct_Hierarchy
H555888 PH05678
H888987 H555888
H8889 H555888
[code]...
Example: I expect the rows with H8889,H9955 & P6666 & P5555 to be sub-category values value for product hierarchy H555888.
If there are rows with H8888987 as Product_hierarchy, we will pull up those rows too for product hierarchy H555888. The extra condition is we drill down only on 7 character mod_prod_number not on 5 character mod_prod_number. We pull out all sub category mod_prod_number for all distinct Product hierarchy.

View 9 Replies View RelatedI want to delete records from parent table which are less than 2 years. Before deleting records from parent table we have to delete records from child table. How can we delete those records. I don't want to use ON DELETE CASCADE.
MASS_MASTER --parent table.
MASS_CHILD --child table.
The below query is used to delete records from parent table.
DELETE FROM mass_master WHERE last_date<=ADD_MONTHS(sysdate,-24);
The child table MASS_CHILD is not having last_date column. provide me the query to delete same records from child table.
