Use the schema you have beenusing for this tutorial.Referenced Table: BOOKSReferenced Constraint: Name (generated by Oracle) of the primary key constraint forthe Books table. (Might be a name with a format like BOOKS_PK.) Be sure that theReferenced Column on BOOKS displayed value is BOOK_ID after you select theReferenced Constraint.Associations: Local Column: BOOK_IDAssociations: Referenced Column on BOOKS: BOOK_ID3. Click OK to finish creating the table.You have finished creating all the tables. To create a sequence for use in generatingunique primary key values for the Patrons table, go to Creating a Sequence.Related TopicsTutorial: Creating Objects for a Small DatabaseSQL Developer User Interface2.4 Creating a SequenceCreate one sequence object, which will be used in INSERT statements to generateunique primary key values in the Patrons table. (You do not need to create a sequencefor the primary key in the Transactions table, because you used the SQL Developerfeature that enables automatic population of primary key values for that table.) Youwill use the Create Sequence dialog box to create the sequence declaratively; thesequence that you create will be essentially the same as if you had entered thefollowing statements using the SQL Worksheet:CREATE SEQUENCE patron_id_seqSTART WITH 100INCREMENT BY 1;After creating the sequence, you can use it in INSERT statements to generate uniquenumeric values. The following example uses the patron_id_seq sequence in creating arow for a new patron (library user), assigning her a patron ID that is the next availablevalue of the patrons_id_seq sequence:INSERT INTO patrons VALUES (patron_id_seq.nextval,'Smith', 'Jane', '123 Main Street', 'Mytown, MA 01234', null);To create the sequence, if you are not already connected, connect to the database as theuser for the schema you are using for this tutorial. Right-click the Sequences node inthe schema hierarchy on the left side, select Create Sequence, and enter informationusing the Create Sequence dialog box.Schema: Specify your current schema as the schema in which to create the sequence.Name: patron_id_seqIncrement: 1Start with: 1002-6 SQL Developer Online Help
