the same names, but they must be of the same data type Foreign key constraints define the relational structure of the database: the many-to-one relationships that connect the table, in their third normal form If the parent table has unique constraints as well as (or instead of) a primary key constraint, these columns can be used as the basis of foreign key constraints, even if they are nullable A foreign key constraint is Just as a unique constraint permits null values de ned on the child table, but a unique or in the constrained column, so does a foreign key primary key constraint must already exist constraint You can insert rows into the child on the parent table table with null foreign key columns even if there is not a row in the parent table with a null value This creates orphan rows and can cause dreadful confusion As a general rule, all the columns in a unique constraint and all the columns in a foreign key constraint are best defined with not null constraints as well; this will often be a business requirement Attempting to inset a row in the child table for which there is no matching row in the parent table will give an error Similarly, deleting a row in the parent table will give an error if there are already rows referring to it in the child table There are two techniques for changing this behavior First, the constraint may be created as ON DELETE CASCADE This means that if a row in the parent table is deleted, Oracle will search the child table for all the matching rows and delete them too This will happen automatically A less drastic technique is to create the constraint as ON DELETE SET NULL In this case, if a row in the parent table is deleted, Oracle will search the child table for all the matching rows and set the foreign key columns to null This means that the child rows will be orphaned but will still exist If the columns in the child table also have a not null constraint, then the deletion from the parent table will fail It is not possible to drop or truncate the parent table in a foreign key relationship, even if there are no rows in the child table This still applies if the ON DELETE SET NULL or ON DELETE CASCADE clauses were used A variation on the foreign key constraint is the self-referencing foreign key constraint This defines a condition where the parent and child rows exist in the same table An example would be a table of employees, which includes a column for the employee s manager The manager is himself an employee and must exist in the table So if the primary key is the EMPLOYEE_NUMBER column, and the manager is identified by a column MANAGER_NUMBER, then the foreign key constraint will state that the value of the MANAGER_NUMBER column must refer back to a valid EMPLOYEE_ NUMBER If an employee is his own manager, then the row would refer to itself.

A check constraint can be used to enforce simple rules, such as that the value entered in a column must be within a range of values The rule must be an expression that will evaluate to TRUE or FALSE The rules can refer to absolute values entered as literals, or to other columns in the same row, and they may make use of some functions As many check constraints as you want can be applied to one column, but it is not possible to use a subquery to evaluate whether a value is permissible, or to use functions such as SYSDATE The not null constraint is in fact implemented as a preconfigured check constraint

Constraints can be defined when creating a table, or added to the table later When defining constraints at table creation time, the constraint can be defined in line with the column to which it refers, or at the end of the table definition There is more flexibility to using the latter technique For example, it is impossible to define a foreign key constraint that refers to two columns or a check constraint that refers to any column other than that being constrained if the constraint is defined in line, but both these are possible if the constraint is defined at the end of the table For the constraints that require an index (the unique and primary key constraints), the index will be created with the table if the constraint is defined at table creation time Consider these two table creation statements (to which line numbers have been added):
