how can I CREATE Two SQL CREATE VIEW Statements. One of the CREATE VIEW Statements must use two joined tables. Use the two created VIEWS in two different SELECT Statements. One created VIEW per SELECT Statement. Use the SHOW FULL TABLES Statement to list the stored VIEWS in the Database Relational schema The primary key is bold and the foreign key is italic Region(regionID, regionName,
how can I CREATE Two SQL CREATE VIEW Statements. One of the CREATE VIEW Statements must use two joined tables.
- Use the two created VIEWS in two different SELECT Statements. One created VIEW per SELECT Statement.
- Use the SHOW FULL TABLES Statement to list the stored VIEWS in the
Database
- Relational schema
The primary key is bold and the foreign key is italic
Region(regionID, regionName, director)
StateOfRegion(stateCode, stateName, statePopulation, RegionID)
Store(StoreID, phone, manager, address, regionID)
Employee(empID, storeID, empName, hireDate, birthDate, socSecNum)
Supplier(supplierID, SupplierName, contact, email, phone)
StoreSupplier(storeID, supplierID, startDate)
- Meta dataThe metdata for each table from the given ER diagram is as below
