You have a database that stores sales and order information.
Users must be able to extract information from the tables on an ad hoc basis. They must also be able to reference the extracted information as a single table.
You need to implement a solution that allows users to retrieve the data required, based on variables defined at the time of the query.
What should you implement?
A . the COALESCE function
B . a view
C . a table-valued function
D . the TRY_PARSE function
E . a stored procedure
F . the ISNULL function
G . a scalar function
H . the TRY_CONVERT function
Answer: C
Explanation:
User-defined functions that return a table data type can be powerful alternatives to views. These functions are referred to as table-valued functions. A table-valued user-defined function can be used where table or view expressions are allowed in Transact-SQL queries. While views are limited to a single SELECT statement, user-defined functions can contain additional statements that allow more powerful logic than is possible in views. A table-valued user-defined function can also replace stored procedures that return a single result set.
