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
i am running the query from which i am getting below mentioned error how can i find the record which is not there in parent table ora02291 integrety constrain violated and parent key not found.
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 want to get table name, constraint name, constraint type with join processes in string type. this is what i want: alter table tablename add constraint constraintname constrainttype(columnname)
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 need to find the parent and child from the table in this case the parent is Classics & Poetry and child is Literature & Anthologies..the way of getting only the parent and child record from this table.
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.

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.
I have table emp that contains empno, empname, mgr .what i want is a general procedure that will take empno as input and will give all the child rows and parent for entered empno.
for ex
E A-->B-->C-->D F-->G H
When i will pass d as node it will return c,b,a,e,f,g,h
SELECT c.table_name CHILD_TABLE, p.table_name PARENT_TABLE FROM user_constraints p, user_constraints c WHERE (p.constraint_type = 'P' OR p.constraint_type = 'U') AND c.constraint_type = 'R' AND p.constraint_name = c.r_constraint_name AND c.table_name = UPPER('ODS_TSAF_MES_PC');
primary key constraint on transaction_dtl_bk is affecting the insertion of next correct rows.

I have csv file which having parent and child related data.i need to load parent data in to parent table and get parent reference id and store in child table with child data. i am not able to find how to get parenet refernce id using control file. In my csv file i have 2 parent name rows. I need to create one A record in parent table and get that parent primary(P_ID) for 'A' record and put into child table for c_name test1 and test2 records.
My controll file ------------------- LOAD DATA INFILE 'mydata.data' APPEND INTO TABLE parent when (1:1) = 'p' fields terminated by ',' optionally enclosed by '"' trailing nullcols
[code].....
able to load parent data and generate P_ID, but i am not able to get P_ID for child records.

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 want to know constraint name of a particular table if it exists.Here are the queries that i tried to find the constraint name of a particular table but the results were 'no rows selected'.
Queries:
select constraint_name from user_cons_columns where table_name='x'; select constraint_name from user_constraints where table_name='x';
I'm trying to create a new table which has a date field (date of birth) and I want to include a constraint which will not allow me to add values if they are over 21 years old. I'm using SQLPlus .
Can we modifying the existing constraint on table?I have table level UNIQUE constraint on 3 columns of table.I need to modify the UNIQUE constraint to 2 columns? Instead of dropping/recreating the constraint, is there any option to modify the existing constraint
Ex
CREATE TABLE TEST_CONST(NUM1 NUMBER , NUM2 NUMBER , NUM3 NUMBER , UNIQUE (NUM1 ,NUM2,NUM3)); ;
SELECT * FROM USER_CONS_COLUMNS UCC WHERE UCC.TABLE_NAME LIKE 'TEST_CONST';
ALTER TABLE TEST_CONST MODIFY CONSTRAINT SYS_C0025132 UNIQUE(NUM1,NUM2);
