Oracle Foreign Key Constraint: Enforcing Relationship Beween Tables
hi, i'm new to oracle/sqlplus is there a command(s) in sqlplus that will show the parent/child relationships that a particular table possesses? tia!. Viewing the Oracle Archive Table Hierarchy. This task applies to the subclient on the production database. You can view the parent and child relationships when. I do not believe that you would have to use a joiner or a lookup to honor the parent child relationship between the tables. The CDC process will.
Versions may be named using any combination of alphabetic and numeric characters. Parent Number Enter the address book number of the parent entity for example, parent company. The system uses this number to associate a particular address with a parent entity or location.
Any value that you enter in this field updates the Address Organizational Structure Master table F for the specified structure type. This address number must exist in the Address Book Master table F Examples of address book records that would have a parent number include: A parent in one hierarchy can be a child in another hierarchy.
A hierarchy can be organized by business unit, employee, or position. For example, you can create a hierarchy that displays the reporting relationships between employees and supervisors. Address Number Enter a valid address book number. This number identifies an entry in the JD Edwards Address Book system, such as employee, applicant, participant, customer, supplier, tenant, or location. Group Enter a number for the group. This number reorders a group of records on the form.
All Parent - Child tables in the database
Begin Eff Date beginning effective date Enter a valid date. This is the date on which the address number appears in the structure. The Beginning Effective Date field prevents the address number from occurring in the structure until the beginning effective date is the same as the current date. If you select the processing option for tier descriptions in the Structure Revisions program Pyou must complete this field. A parent business object can have a single-cardinality child with ownership and a single-cardinality child without ownership.
Lookup tables are used for relationships without ownership. Ownership is indicated by the value of the Ownership application-specific information. Single-cardinality relationships and data without ownership Typically, each parent business object owns the data within the child business object that it contains.
For example, if each Customer business object contains one Address business object, when a new customer is created, a new row is inserted into both the Customer and Address tables. The new address is unique to the new customer. Likewise, when deleting a customer from the Customer table, the customer's address is also deleted from the Address table. However, situations can occur in which multiple hierarchical business objects contain the same data, which none of them owns.
For example, assume that the Address database table contains a reference to the StateProvince lookup table. Because the lookup table is rarely updated and is maintained independently of the address data, creating or modifying address data does not affect the state and province data in the lookup table.

However, to be able to retrieve the StateProvince business object along with the Address business object, StateProvince must be a single-cardinality child of Address and the relationship must be defined without data ownership. If your database design includes lookup tables, your business object design differs slightly from the database design.
This is because the adapter retrieves data only for a table business object and its child table business objects. To use a lookup table, you need to create a single-cardinality parent-child relationship between the tables, without ownership.
Parent child relationship in Oracle - Stack Overflow
Although the StateProvince lookup table is not a child of the Address table in the database, the corresponding StateProvince business object is a single-cardinality child of the Address table business object because each address contains a single state or province.
However, the Address business object does not "own" the StateProvince business object. Changes to an address do not result in a change to the list of states and provinces.
When the adapter receives a hierarchical business object with a Create, Delete, or Update request, the adapter does not create, delete, or update single-cardinality child business objects contained without ownership. The adapter performs only Retrieve operations on these business objects. If the adapter fails to retrieve such a single-cardinality business object, it returns an error and stops processing; it does not add or change values in the lookup table's business object. Denormalized data and data without ownership In addition to facilitating the use of static lookup tables, containment without ownership provides another capability:
