You have two existing tables, one named COUNTRY and the other named STATES.
The tables are defined as follows:
You need to set up a rule that every STATE.Country_Abbr must match an existing record in the COUNTRY table.
Develop the solution by selecting and arranging the required code blocks in the correct order.
You may not need all of the code blocks.

Note:
To allow naming of a FOREIGN KEY constraint, and for defining a FOREIGN KEY constraint on multiple columns, use the following SQL syntax:
MySQL / SQL Server / Oracle / MS Access:
ALTER TABLE Orders ADD CONSTRAINT fk_PerOrders FOREIGN KEY (P_Id) REFERENCES Persons(P_Id)
You create a table named Customers by using the following code segment:
You create a non-clustered index named IX_Name on the name column.
You write the following query to retrieve all of the customers that have a name that starts with the letters SMI:
You discover that the query performs a table scan.
You need to ensure that the query uses the index.

You have a SQL Server 2012 database named Database1. Database1 has a data file named database1_data.mdf and a transaction log file named database1_Log.ldf. Database1_Data.mdf is
1.5 GB
Database1_Log.ldf is 1.5 terabytes. A full backup of Database1 is performed every day.
You need to reduce the size of the log file. The solution must ensure that you can perform transaction log backups in the future. Which code segment should you execute? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.

正解：
1 - USE Database1;
2 - ALTER DATABASE Database1 SET RECOVERY SIMPLE;
3 - DBCC SHRINKFILE (Database1_Log);
4 - ALTER DATABASE Database1 SET RECOVERY FULL;
Explanation:
Shrinking a log file to a specified target size
The following example shrinks the log file in the AdventureWorks database to 1 MB. To allow the DBCC SHRINKFILE command to shrink the file, the file is first truncated by setting the database recovery model to SIMPLE.
Transact-SQL
USE AdventureWorks2012;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE AdventureWorks2012
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (AdventureWorks2012_Log, 1);
GO
-- Reset the database recovery model.
ALTER DATABASE AdventureWorks2012
SET RECOVERY FULL;
GO
