Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You are developing a database to track customer orders. The database contains the following tables: Sales.Customers, Sales.Orders, and Sales.OrderLines.
The following table describes the columns in Sales.Customers.
< ><>>< ><>>< ><>>- >>- >- >>< >
Solution:
Box 1: FUNCTION
To be able to return a value we should use a scalar function.
CREATE FUNCTION creates a user-defined function in SQL Server and Azure SQL Database. The return value can either be a scalar (single) value or a table.
Box 2: RETURNS decimal(18,2)
Use the same data format as used in the UnitPrice column. Box 3: BEGIN
Transact-SQL Scalar Function Syntax include the BEGIN ..END construct.
CREATE [ OR ALTER ] FUNCTION [ schema_name. ] function_name
( [ { @parameter_name [ AS ][ type_schema_name. ] parameter_data_type [ = default ] [ READONLY ] }
[ ,...n ]
]
)
RETURNS return_data_type
[ WITH [ ,...n ] ] [ AS ]
BEGIN
function_body
RETURN scalar_expression END
[ ; ]
Box 4: @OrderPrice * @CalculatedTaxRate Calculate the price including tax.
Box 5: END
Transact-SQL Scalar Function Syntax include the BEGIN ..END construct. References: https://msdn.microsoft.com/en-us/library/ms186755.aspx
