Q68. You have a Microsoft SQL Azure database named DBAzurel. DBAzurel contains a table named Orders that stores sales data.
Each order has a sales total that can only be discovered by querying multiple tables.
You need to ensure that the value of the sales total is returned by executing a query on Orders.
What should you create?
A. A calculated column that uses a scalar function
B. A trigger that uses a table-valued function
C. A calculated column that uses a table-valued function
D. A trigger that uses a ranking function
Answer: C
Explanation: A table-valued parameter is scoped to the stored procedure, function, or
dynamic Transact-SQL text, exactly like other parameters. Similarly, a variable of table type
has scope like any other local variable that is created by using a DECLARE statement. You
can declare table-valued variables within dynamic Transact-SQL statements and pass
these variables as table-valued parameters to stored procedures and functions.
Table-valued parameters offer more flexibility and in some cases better performance than
temporary tables or other ways to pass a list of parameters.
Incorrect:
Not A: A scalar function would only be able to use other columns from the same table.
Q69. You are creating a table named Orders.
You need to ensure that every time a new row is added to the Orders table, a user-defined function is called to validate the row before the row is added to the table.
What should you use?
More than one answer choice may achieve the goal. Select the BEST answer.
A. A data manipulation language (DML) trigger
B. A DEFAULT constraint
C. A Data Definition Language (DDL) trigger
D. A CHECK constraint
E. A FOREIGN KEY constraint
Answer: D
