SQL & PL/SQL :: Multiple Of Same Constraint Keys In Parent Table?
Jun 9, 2011
I used
SELECT USER_CONS_COLUMNS.CONSTRAINT_NAME,
COLUMN_NAME,
CONSTRAINT_TYPE,
[Code]...
to create a parent key table sort of thing, but for some reason there are rows that display multiple times
CONSTRAINT_NAME COLUMN_NAME CONSTRAINT_TYPE R_CONSTRAINT_NAME DELETE_RU
-------------------- -------------------- --------------- ------------------------------ ---------
SYS_C00135225 PATIENT_STATUS C
SYS_C00135226 BALANCE C
SYS_C00135227 PATIENT_STATUS C
PK_PATIENT PATIENT_NUMBER C
[Code] ..........
is it something to do with the join command

i need to delete a record from table but it showed a error for foreign key constraint so i disabled the constraint and again deleted, now the row is deleted.
Again inserted another values instead the deleted value. after that i tried to alter the constraint but i received the error ORA-02298 cannot validate - Parent keys not found
alter table t1 enable constraint FK_T1;
But i am not able to enable the key. what to do?

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 two different java process trying to insert in the same time in the same table for the same trade. The structure of the table Report is
create table report
( TRADE_ID NUMBER,
VERSION NUMBER,
MESSAGE_TIME TIMESTAMP)
There is a unique key on (TRADE_ID and VERSION) So if a new trade_id is inserted, the version is set to 1 and the second becomes 2 and so on. The version is calculated as last version of the trade_id ie. version + 1. It was woking fine till a new Java process was build that fired inserts through ten different java instances at the same time resulting in unique key error. So in detail what is hapenning is if three records of trade_id's comes in at the same time it should allocate versions in a first come first serve basis and there should be three versions of trade id 1,2 and 3. Now due to the multiple instances they all seems to get fired at once and all ending up with version one and thus resulting in unique key constrain error while trying to insert into the table.

the relationship on my script.What I want to do is make it possible to assign many courses to a student.But I have read a few books on foreign keys and primary keys, and I still dont get how to go on doing this....
This is how the table creation with the keys looks right now...
CREATE TABLE CAMPUS (
CAMPUSID NUMBER(4) NOT NULL,
NAME VARCHAR2(80) NOT NULL,
CONSTRAINT CAMPUS_PK PRIMARY KEY (CAMPUSID));

I need to copy the changed and deleted data in an other table. I have searched this site ,asktom and other sites also. I found the following solution from asktom website. But it gives me the changed columns data only and i need the primary key with changed data and deleted rows also.
DROP TABLE emp;
CREATE TABLE emp AS (SELECT * FROM scott.emp);
CREATE TABLE audit_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.

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 t2(c number, d number references t1(a));

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.

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).

how to i insert a constraint of words into the table example below.I am new to this stuff man.
Create table Orders
(
orderID Number(8) Primary Key,
orderDate Date Not Null,
methPmt Varchar2(10),
custID Number(5),
orderSource Number(2),
Foreign Key(custID) Reference Customer(custID),
Foreign Key(ordersource) Reference OrderSource(ordersource)

The catch is I am required to enter a constraint of the methPmt will only take values of "CASH", "CREDIT" or "CHEQUE" only.
How am I suppose to enter this constraint value into the creation of this table?

SELECT * FROM USER_CONS_COLUMNS UCC WHERE UCC.TABLE_NAME LIKE 'TEST_CONST';
ALTER TABLE TEST_CONST MODIFY CONSTRAINT SYS_C0025132 UNIQUE(NUM1,NUM2);
