You have a database named DB1 that contains the following tables: Customer, CustomerToAccountBridge, and CustomerDetails. The three tables are part of the Sales schema. The database also contains a schema named Website. You create the Customer table by running the following Transact-SQL statement:
The value of the CustomerStatus column is equal to one for active customers. The value of the Account1Status and Account2Status columns are equal to one for active accounts. The following table displays selected columns and rows from the Customer table.
You plan to create a view named Website.Customer and a view named Sales.FemaleCustomers. Website.Customer must meet the following requirements:
Allow users access to the CustomerName and CustomerNumber columns for active customers.
Allow changes to the columns that the view references. Modified data must be visible through the view.
Prevent the view from being published as part of Microsoft SQL Server replication. Sales.Female.Customers must meet the following requirements:
Allow users access to the CustomerName, Address, City, State and PostalCode columns.
Prevent changes to the columns that the view references.
Only allow updates through the views that adhere to the view filter.
You have the following stored procedures: spDeleteCustAcctRelationship and spUpdateCustomerSummary. The spUpdateCustomerSummary stored procedure was created by running the following Transacr-SQL statement:
You run the spUpdateCustomerSummary stored procedure to make changes to customer account summaries. Other stored procedures call the spDeleteCustAcctRelationship to delete records from the CustomerToAccountBridge table.
You must update the design of the Customer table to meet the following requirements.
You must be able to store up to 50 accounts for each customer.
