I have loaded into an Oracle table defined as XMLTYPE. I'm okay with PL-SQL and stored procedures, where I will ultimately do this processing once I get a handle on XML DB querying from an XMLTYPE table.
Based on reading the oracle documentation about XML DB, and more importantly, reading dozens of posts to this forum,I have been successful in loading the XML files into a SQL XMLTYPE table and doing simple queries against that table to retrieve some of its data so that I can then insert that data into other target oracle relational tables.
how to select parent/child data from XMLTYPE tables. I am able to follow the forum examples and can replicate the methods shown on the many example XML contents shown on this forum, but not against the XML that I have to process. I am wondering if my struggle is caused by my lack of knowledge, or by ill-formed XML content supplied to me by the educational vendor.The XML content has structured the XML content nodes in such a way that I do not seem to be able to apply the parent/child sql methods.I have been able to use for other XML examples I have tested against.
My XML file shown below represents High School Transcript data, for which I need to be able to parse out into my own oracle relational tables for that student, his personal info, and his course info, etc. i.e., for our example, which courses he has taken for which High School grade levels. The vendor-supplied XML seems to put the Courses and the High School grade level in "parallel nodes," instead of parent/child nodes, so I am struggling to be able to use SQL to differentiate which course the student took in NinthGrade versus TenthGrade.
-- WHat I would like to determine from a select statement:
LASTNAME GradeLevel COURSETITLE
=============================
Smith NinthGrade PHYS ED 101
Smith TenthGrade CALCULUS 201
Smith TenthGrade ZOOLOGY 202
(The data has been simpliied and masked, but is true to the content and is queryable).

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.

I have a parent table and child table. I want a row to be deleted from the parent table which is referenced by a child row. Is there a way to achieve this. I dont have permission to re create the table or alter the table using delete cascade option. Is there a way to do it in sql.
SQL> create table t1(a number primary key, b number);
SQL> create table t2(c number, d number references t1(a));
SQL> insert into t1 values(1,2);
SQL> insert into t1 values(2,3);
SQL> insert into t1 values(3,4);
SQL> insert into t2 values(10,3);
SQL> insert into t2 values(20,2);
SQL> delete from t1 where a=2;
delete from t1 where a=2

I 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.

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.

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'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 5,200,900 from dual union all
select 6,300,400 from dual union all
select 7,101,500 from dual union all
select 8,102,500 from dual union all
select 9,103,500 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
4 100 1 501
4 100 2 502
4 100 3 503
5 200 1 501
5 200 2 502
5 200 3 503
6 300 6 400
7 101 7 500
8 102 8 500
9 103 9 500
10 201 10 600
11 201 11 601
12 201 12 602
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.

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');

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 |

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;
BEGIN

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;

I need to fech parent records only when no child record with status 'N' exists. There are only two possible values for status column of child table 'Y' / 'N'.
Below are table structures and insert statements for data.
CREATE TABLE MASTER
(
COL1 NUMBER,
[Code]....
COMMIT;Query I framed is below
select * from master where exists (select null from child where child.col2 = master.col1
group by child.col2 having count(distinct col3) =1 )
Output in above case would be 3 as for 1 there's one record with status as 'N' and for 2 there's no child record. I am on 10g.

I need to get the super set(parent) record from a relational table. Following is the structure of the table,
create table relation (data_field1 number(20),data_field2 number(20),data_field3 number(20),
primary key (data_field1,data_field2,data_field3) );
insert into relation (data_field1, data_field2, data_field3) values (-10,123,334);
insert into relation (data_field1, data_field2, data_field3) values (200,123,334);
insert into relation (data_field1, data_field2, data_field3) values (300,123,334);
insert into relation (data_field1, data_field2, data_field3) values (400,123,334);
[code].....
Here '-10' will be considered as parent(super set) for all other values. If i have records like below,
-10 200 300
100 200 300
123 200 300
521 201 300
Output should only contain two rows. A super set row and other distinct row(second column value is not equivalent to super set).
