You have a data warehouse that includes a table named [Fact]. [sales]. The table has four partitions. There are no foreign keys defined on the [Fact].[sales] table.
You identify an issue with the first partition. You must reload the data for the first partition as quickly as possible.
You need to prepare the partition for reloading data.
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

You manage a data warehouse in a Microsoft SQL Server instance. Company employee information is imported from the human resources system to a table named Employee in the data warehouse instance. The Employee table was created by running the query shown in the Employee Schema exhibit. (Click the Exhibit button.)

The personal identification number is stored in a column named EmployeeSSN. All values in the EmployeeSSN column must be unique.
When importing employee data, you receive the error message shown in the SQL Error exhibit. (Click the Exhibit button.).

You determine that the Transact-SQL statement shown in the Data Load exhibit in the cause of the error.
(Click the Exhibit button.)

You remove the constraint on the EmployeeSSN column. You need to ensure that values in the EmployeeSSN column are unique.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.

Explanation

With the ANSI standards SQL:92, SQL:1999 and SQL:2003, an UNIQUE constraint must disallow duplicate non-NULL values but accept multiple NULL values.
In the Microsoft world of SQL Server however, a single NULL is allowed but multiple NULLs are not.
From SQL Server 2008, you can define a unique filtered index based on a predicate that excludes NULLs.

You are the administrator of a database that hosts tables for a data warehouse.
The table named Fact1 has data from the start of calendar year 2011 through the end of 2017. The table contains at least 20 million rows of data for each year. You create the table by running the following Transact-SQL statement:
CREATE PARTITION FUNCTION PartitionFunc-Fact1(SMALLINT)
AS RANGE LIFT VALUES(2012, 2013, 2014, 2015)
You need to modify the partition function so that rows for each calendar year are in a separate partition. You must also move all data prior to 2014 to another table named Fact1_old.
How should you complete the Transact-SQL statement? To answer, select the appropriate Transact-SQL segment in the dialog box in the answer area.
NOTE: Each correct selection is worth one point.
