• SQL statement error INSERT The conflicted with the FOREIGN KEY constraint

  I recently installed a reporting for vmware vsphere software, but I get a SQL error. I opened a request for assistance with vmware, but so far they have not come up with a solution.

• integrity of foreign key error

  I had the departments and officials from two tables
  employee table has a foreign key that is a primary key in the departments table
  IE department_id
  every time I try to delete records from the employee table using the department_id IE a foreign key
  then it displays error
  but when I do it through other constraints then the lines are to remove
  so why can't delete lines in the employees table using department_id which is a foreign key in the employees table
  and the primary key for the departments table?

  guys, it's really easy when you really look at the error message:

  The violation is not the FK on employees.department_id. (the name will be EMP_DEPT_FK)
  The violation is against the FK hr.dept_mgr_fk which refers to the column manager_id (employee id) in the departments. When you try to remove all dept 50 employees, you also try to remove the service manager, but which is not allowed due to the FK of departments. Try this:

  update departments set manager_id = null where id = 50;
  delete from employees where department_id = 50;

• Foreign key Error Message ORA - 01430

  I have a LSU_INTER_RESOURCES_T table name. I would like to add a constraint foreign key with the following command:
  
  ALTER table lsu_inter_message_t
  Add constraint inter_message_id_fk
  inter_request_id lsu_inter_requests_t (inter_request_id) ON DELETE CASCADE REFERENCES;
  
  The system returned the error message:
  ORA - 01430: added column already exists.
  
  If I drop the inter_request_id column I'll lose data, and when I create the constraint it places the column at the end of the table. Data loss is not a problem now because the table has no data, but down the line, I see that there is a real problem.
  
  I would like to have the foreign key defined in the sequence column, I chose when I designed the tabular presentation. IE I want to all key columns placed at the beginning of the table online.
  
  Can I move the column after that I have set it and how this is done? Is this a feature of 10g?
  
  Thank you, Ned

  Try

  alter table lsu_inter_message_t
  add constraint inter_message_id_fk
  foreign key(inter_request_id ) REFERENCES lsu_inter_requests_t(inter_request_id) ON DELETE CASCADE;
  

• Error during DELETING foreign key violation lasts to self referential FK

  DB version: 10 gr 2
  
  In the example below, I have a self referencing foreign key mgr. When I DELETE records
  I don't get an error ORA-02292 of self referencing FK.
  

  create table emp2 
   (
   empno number primary key,

  SQL>DELETE FROM EMP2;
  
  3 rows deleted.

  But in one of our tables of Production which has an auto referential FK, I get an error similar to

  ERROR at line 1:
  ORA-02292: integrity constraint (SCOTT.EMP2_FK) violated - child record found

  When I try to delete records. No idea why I get this error?

  Hi Garry,

  Your FK said "all Manager must be an employee."

  If this statement

  DELETE FROM EMP3 WHERE EMPNO<5;
  

  which is a gross violation from the Manager of EMPNO = 6 would not be an employee.

  How do you solve that?

  Expected EMPNO = deleted 6?
  Should EMPNO = 6 I have a new Manager?
  Should EMPNO = 6 has no handler?

  But,

• Update fails because of a foreign key constraint

  Hello.
  
  I have several tables in my database but 3 are important. One of them is used (Employee_ID, Last_Name and other irrelevant columns name), dentist (employe_id, Qualifications) and Wizard (Employee_ID, Qualifications).
  I am applying in Oracle Application Express and trying to update a row in the Employee table, I get an ORA-20505: error in DML: p_rowid = 96, p_alt_rowid = employe_id, p_rowid2 =, p_alt_rowid2 is. ORA-02292: integrity constraint (DB. Dentist_CON) violated - book of the foundling
  
  Now, first of all, I had the same problems with the removal of lines, but I've solved that by adding a delete cascade on foreign keys.
  I have key constraints foreign both in my paintings dentist and Assistant in columns Employee_ID and these refer to Employee_ID in the Employee table.
  
  When I update anything in my Express request form, I've allowed users to do anything of my Employee table primary key (employe_id). Any changes that might occur therefore columns unrelated to the primary key. For example, if I change the name of a particular line column I can't update because I get the above error.
  
  I don't understand why this is happening.
  If I could get a glimpse, why this is happening or using any I would be very happy.
  
  Thanks in advance.

• How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

  Forgive my question. I am very new to Oracle.

  How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

  Is that not all the primary key and FOREIGN KEY on?

  My paintings:

  I created 2 tables and connect to apply in the data base referential integrity, as I learned.

  CREATE TABLE - parent provider

  (the numeric (10) of supplier_id not null,)

  supplier_name varchar2 (50) not null,

  Contact_Name varchar2 (50).

  CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

  );

  CREATE TABLE - child products

  (the numeric (10) of product_id not null,)

  supplier_id numeric (10) not null,

  CONSTRAINT fk_supplier

  FOREIGN KEY (supplier_id)

  REFERENCES beg (supplier_id)

  );

  I inserted the following text:

  INSERT INTO provider

  (supplier_id, supplier_name, contact_name)

  VALUES

  (5000, 'Apple', 'first name');

  I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

  How to get there?

  Thanks in advance!

  Hello

  What is a foreign key in Oracle?

  A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

  Ok!??

  What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

  A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

  If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

  Muzz

  Hello Muzz,

  Perhaps the example of human Chen reveals a design error.
  If a student has a 'teacher_id' "teacher" FK and FK for "emp" becaue each teacher is an EMP, I guess that the correct design would be to have only the FK of 'teacher' and to have another pointing to the 'emp' table in the 'teacher' tabe FK

  But we can imagine comical situations...
  CREATE TABLE PEOPLE (id NUMBER of KEY PRIMARY, name VARCHAR2 (20 CHAR),...);
  CREATE TABLE SCIENTIST (id people KEY PRIMARY NUMBER (id) REFERENCES, discipline VARCHAR2 (20 CHAR),...);
  CREATE TABLE POLICEMAN (id REFERENCES to KEY PRIMARY NUMBER (id), hire_date people DATE,...);

  First table = all.
  2nd: a subset of the first, with people having the profile of 'scientific '...
  3rd: a subset of the first, with people being a policeman.
  It might be people first table and in none of the 2nd and 3rd, 1st and 2nd, 1st and 3rd only or in the 3 tables.

  Then we can have a fourth table of 'something' referring to a person who must be a scientist and a police officer.

• Is a foreign key MUST have a UNIQUE or PK column as a reference?

  First I tried, from what I saw Yes it must be Unique or PK. Secondly, I am pretty sure that I read somewhere where there are PK or unique. Thirdly, I checked oradocs and other pages, the thing ends, I owe an answer

  Constraint foreign key (also called a constraint referential integrity) designates a column as a foreign key and establishes a relationship between this foreign key and a primary or unique key specified, called the referenced key.

  
  

  This implies, but does not explicitly specify that it MUST be a PK or a SINGLE.

  
  

  Basically I want a simple yes/no answer just to give me some peace of mind. I don't want to waste any time, but changes to the oracle from time to time, and I'd rather have a confirmation from someone with more knowledge/experience.

  
  

  Thank you!

  Yes.

  This same document you are referencing tells you what are the rules for the creation of a foreign key.

  Data integrity

  Foreign key constraints

  Whenever two tables have one or more common columns, Oracle database can apply the relationship between the two tables with a foreign key, also called a referential integrity constraint constraint. The constraint requires that for each value in the column on which the constraint is defined, the value in the other specified that another table and column must match. An example of a referential integrity rule is that an employee may work for only one Department.

  Table 5-2 lists the terms associated with referential integrity constraints.

  Table 5-2 referential integrity constraint conditions

  Term

  Definition

  Foreign key

  The column or set of columns included in the constraint definition that refers to a key that is referenced. For example, the department_id column employees is a foreign key that refers to the department_id column of departments . Foreign keys can be described as several columns. However, a composite foreign key must refer to a primary or unique key with the same number of columns and the same types of data.

  The value of the foreign keys can be either the primary or unique key value referenced or be null. If any column of a composite foreign key is null, then the portions not null the key do not match any corresponding part of a parent key.

  Referenced key

  The unique key or the primary key of the table referenced by a foreign key. For example, the department_id column departments is the key referenced to the department_id column of employees .

  Table dependent or child

  The table containing the foreign key. This table is based on the values present in the primary or unique key referenced. For example, the employees table is a child of departments .

  Referenced or the parents table

  The table that is referenced by the foreign key of the child table. It is the key to this table reference that determines whether specific inserts or updates are allowed in the child table. For example, the departments table is a parent of employees .

  The first three terms defined in the table EXPLICITLY State references to the 'core' or 'unique' keys to the parent.

  The doc also refers to the Application Developer Guide:

  Maintaining the integrity of the data in Database Applications

  Foreign key references a primary key by default

  If the list of columns is not included in the REFERENCES option when you set a FOREIGN KEY constraint (simple or composite column), then Oracle database assumes that you want to reference the primary key of the specified table. You can also explicitly specify the columns to reference the table parent in parentheses. Oracle database checks automatically to check this list of column refers to a primary or unique to the parent table key. If it isn't, an informative error is returned.

  That the entire paragraph is as explicitly as it gets.

  No list of columns? Oracle then checks for a primary key.

  There is a list of columns? Then Oracle 'control to verify this list of column made reference to a primary or unique key'...

• Online syntax to create Foreign key with Alter Table statement

  I am a pretty meticulous reader. That being said, from the 4 texts that I read to start to learn SQL, I do not remember and do more that probably not, find a syntax online for the creation of a CF with the statement alter table.

  Just something I thought while I was reading.

  Is there a such syntax?

  And if so someone can give me direction on my code?

  ALTER table emp4 change employee_id key foreign employees of references (employe_id);

  It gives me the option error invalid alter table.

  Any idea would be appreciated.

  Thank you.

  It is clear from the content of the xml file, you have given here. In this xml file, you have four type of complex. Two of them are employed and address. However the employee doesnot has nothing to do with the address that you have not added the relationship. That is why its failure. This isn't the fault of the ODI.

  Also I suggest not to use self-generated by ODI dtd that you might face problem in the future. For example, the address of XML type has 8 attributes, and 4 of them are not mandatory. This means that each of your xml file may have attributes between 4 and 8.  That's where ODI auto generated DTD fails.

  You can, however, create a VIRTUAL column in the parent table, and then create a foreign key that references.

  Thank you

  There is no keyword to remove not limited to Oracle.  Stop the removal of the parent if there is a child is the default unless overridden by a waterfall, or null.  Otherwise, you can never delete a parent in Oracle.

• missing closing parenthesis when creating foreign key

  Schema1.Table1 ALTER TABLE ADD (CONSTRAINT test_FK

  Please help, I tried several times. But I still get the same error

  Delete the TABLESPACE of INDEX clause to HELP.  It is not valid here.

  Create a foreign key does not implicitly create an index.  Since there is no index, there is no tablespace to worry.  As a general rule, you don't want to create an index to support the how foreign key constraint there a sense perhaps specify a tablespace.
