Parent Child Relationship
May 13, 2011Just 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?
SQL & PL/SQL :: Creating Parent Child Relationship
Aug 8, 2011I have a table called FAMILY which holda the data like , for father_gen_1 --->father_gen_2 --> father_gen_3 -- son.

SQL & PL/SQL :: Delete - Parent / Child Relationship
May 22, 2012I 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');

SQL & PL/SQL :: Procedure To Get Path From Parent-child Relationship?
Apr 23, 2010I 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;

SQL & PL/SQL :: Create Complete Hierarchical Table From Table With Only Two Columns - Parent And Child
Aug 13, 2012We 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.

XML DB :: How To Select Parent / Child Related Data From XMLTYPE Table

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).

Compare Two Columns Relationship

1106011640
1106011142
1106011095
1106013029
1106014058
I run the following query to get below of all the combinaiton (note, I am opting out those six rows which matches to each other) select a.Col2 as Col1, b.Col2 as Col2 from RelationshipX a, RelationshipX b
where a.Col1 = 11060
and a.Col1=b.Col1
and a.Col2 <> b.Col2
order by Col1, Col2

How Is Relationship Between MEMORY_TARGET And SGA_MAX_SIZE Parameters
Jun 28, 2012I was just wondering how is the relationship between MEMORY_TARGET and SGA_MAX_SIZE parameters, if exists any at all.I set my memory parameters as:
# Enable AMM
MEMORY_MAX_SIZE=10G
MEMORY_TARGET=4G
# Disable ASMM
SGA_TARGET=0
SGA_MAX_SIZE=0
So I bounce my instances and when I checked the parameter SGA_MAX_SIZE, Oracle automatically set a value of 2456M to it:
sga_max_size big integer 2456M
sga_target big integer 0
Reading MOS ID 443746.1, there is no clear mention about this relationship. It seems that Oracle automatically set SGA_MAX_SIZE as 60% of MEMORY_TARGET.
In am running Oracle 11gR2 (11.2.0.2.3) under Red Hat Linux.
PL/SQL :: Possible To Maintain Primary Key And Foreign Key Relationship
Nov 16, 2012I have a requirement like below
I have 3 tables (Prospect,customer,user) and I have a contact_dtls table .
In prospect table Prospect_id is the primary like this customer_id in customer table and user_id in the user table
in the contact_dtls table I have a column contact_id and other cols.The contact_id can be from prospect_id,customer_id and user_id in other words we can tell the prospect can be a contact or the customer can be a contact and the user also can be a contact also.
Now the question is "is it possible to maintain primary key and foreign key relationship with this design that means the prospect_id,customer_id and user_id would be the foreign keys to the contact_dtls table.
