正確答案: D
You execute IndexManagement.sql and you receive the following error message:
"Msg 512, Level 16, State 1, Line 12
Subquery returned more than 1 value. This is not permitted when the subquery follows =,! =, <, <= ,>, > = or when the subquery is used as an expression." You need to ensure that IndexManagement.sql executes properly.
Which WHILE statement should you use at line 18?

正確答案: A
You have a table named Table1. Table1 has 1 million rows.
Table1 has a columnstore index for a column named Column1.
You need to import data to Table1. The solution must minimize the amount of time it takes to import the data.
What should you do?
To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

正確答案:
1 - Create a table named Table2 by using the same schema as Table1.
2 - Partition Table1.
3 - Import the data to Table2.
4 - Create a columnstore index on Table2 for Column1.
5 - Switch Table2 toTable1.
Explanation:
Note:
* An xVelocity memory optimized columnstore index, groups and stores data for each column and then joins all the columns to complete the whole index.
Columnstore indexes can transform the data warehousing experience for users by enabling faster performance for common data warehousing queries such as filtering, aggregating, grouping, and star-join queries.
* Tables that have a columnstore index cannot be updated.
There are three ways to work around this problem.
A) To update a table with a columnstore index, drop the columnstore index, perform any required INSERT, DELETE, UPDATE, or MERGE operations, and then rebuild the columnstore index.
B) (applies in this scenario) Partition the table and switch partitions. For a bulk insert, insert data into a staging table, build a columnstore index on the staging table, and then switch the staging table into an empty partition. For other updates, switch a partition out of the main table into a staging table, disable or drop the columnstore index on the staging table, perform the update operations, rebuild or re-create the columnstore index on the staging table, and then switch the staging table back into the main table.
C) Place static data into a main table with a columnstore index, and put new data and recent data likely to change, into a separate table with the same schema that does not have a columnstore index.
You have a database named Database1. Database1 has two stored procedures named Proc1 and Proc2 and a table named Table1. Table1 has millions of rows.
Proc1 updates data in Table1. Proc2 reads data from Table1.
You discover that when Proc1 is executed to update more than 4,000 rows, Proc2 is blocked. The block affects all rows, including those that are not being updated by Proc1.
You need to ensure that when Proc1 is executing, Proc2 can access the data in Table1 that Proc1 is not updating.
What should you change Proc1 to do?
More than one answer choice may achieve the goal. Select the BEST answer.
