The entire contents of this database, including database options, are copied to the new database. Thus, if you modify this database, all databases created afterward will inherit those changes. OUTER JOIN types return only non-matching tuples. When we create a primary key (PK) some Database Management Systems (DBMS) automaticallly create a Foreign Key constraint on the attributes of the PK. SQL Server DBMS is one of these DBMSs. If a relation has more than one candidate key, we can implement this by creating a Primary Key constraint for one of the candidate keys, and a UNIQUE constraint for each and every one of the alternate keys. Using the Query Editor Window, “select TOP 1000 Rows” retrieves the first 1000 tuples of a relation (assuming that the relation has 1000 or more tuples). If there is…
- Write SQL code for the following design schema of three tables. The tables should have the following properties: sales table has a primary key on SalesNumber and it is set to AUTO-INCREMENT.products table has a primary key on number and it is set to AUTO-INCREMENT, they is an unique index on prodidsalesdetails table has a primary key on number and it is set to AUTO-INCREMENT, they is an index on prodid. They is a one-to-many relationship between the salesdetails.SalesNumber andsales.SalesNumber fields. There is a one-to-many relationship between the products.prodid and salesdetails.prodid fields. There is to be a delete constraint on the product.prodid field a record in the product table should not be allowed to be deleted if they exist a matching prodid in the salesdetails table. Primary and foreign keys should be implemented in the appropriate tables. Referential Integrity should be enforce at the database level, where appropriate for example, if a sales record is deleted all…Primary keys and candidate keys may both be assigned to the same attribute.Implement a new independent entity phone in the Sakila database. Attributes and relationships are shown in the diagram below The diagram uses Sakila naming conventions.

Implement the has relationships as foreign keys in the Sakila customer, staff, and store tables. Remove the existing phone column from the Sakila address table. Step 2 requires adding a foreign key constraint to an existing table.
