You need to write a query that displays:

Which three Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: FROM ..

Box 2: LAG (not LEAD)

Lag accesses data from a previous row in the same result set without the use of a self-join starting

with SQL Server 2012 (11.x). LAG provides access to a row at a given physical offset that comes before the current row. Use this analytic function in a SELECT statement to compare values in the current row with values in a previous row.

Not lead: Lead accesses data from a subsequent row in the same result set without the use of a self-join starting with SQL Server 2012 (11.x). LEAD provides access to a row at a given physical offset that follows the current row.

Box 3: GROY BY PRO.NAME, YEAR (OrderDate)

Your Microsoft SQL Server database contains tables as shown below.

You have tables that were created by running the following Transact-SQL statements:

The Product table contains 10,000 records. The maximum ProductID is 11,000.

There are 12 rows in the Category table. The maximum CategoryID is 12.

The Product table contains at least one product in every category.

Data in the tables was accidently modified. To correct this, you need to make some updates directly to the tables. You issue several statements.

Which result or results will you obtain for each Transact-SQL statement? To answer, drag the appropriate results to the correct Transact-SQL statements. Each result 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.

Which operator or operators should you use? To answer, drag the appropriate operators to the correct operations. Each operator 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.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: UNION ALL

UNION combines the results of two or more queries into a single result set that includes all the rows that belong to all queries in the union.

UNION ALL Incorporates all rows into the results. This includes duplicates. If ALL is not specified, duplicate rows are removed.

Box 2: INTERSECT

INTERSECT returns distinct rows that are output by both the left and right input queries operator.

Box 3: INNER JOIN

The INNER JOIN keyword selects records that have matching values in both tables.

Box 4: MERGE

Merge performs insert, update, or delete operations on a target table based on the results of a join with a source table. For example, you can synchronize two tables by inserting, updating, or deleting rows in one table based on differences found in the other table.

Box 5: FULL OUTER JOIN

The FULL OUTER JOIN keyword return all records when there is a match in either left (table1) or right (table2) table records.

Note: FULL OUTER JOIN can potentially return very large result-sets!

You are the administrator for a heavily-used OLTP Microsoft SQL Server database.

You are troubleshooting performance issues seen when using stored procedures in the database. The database stores millions of orders across thousands of customers. Some of the customers have large numbers of orders, while others have only one order. You update the statistics and perform defragmentation of all tables and indexes, but two stored procedures still have issues when accessing data.

p_GetCustomer accepts @companyID as a parameter. From the results of profiling, you know that 90 percent of the calls use the @companyid value of 5, while the other 10 percent of calls are evenly distributed across another 10000 values. While viewing the execution plan, you discover that a non-clustered index seek is used.

p_GetShipDate accepts @orderID as a parameter and returns the ship date for that order. You discover that the execution plan is performing a scan on a non-clustered index that has orderID as the index key.

You need to add appropriate query hints to each stored procedure to improve the performance.

What should you do? To answer, drag the appropriate procedures to the correct hints. Each procedure 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.

Correct Answer:

Explanation:

Box 1: Optimize FOR..

OPTIMIZE FOR ( @variable_name { UNKNOWN | = literal_constant } [ , …n ] ) Instructs the query optimizer to use a particular value for a local variable when the query is compiled and optimized. The value is used only during query optimization, and not during query execution.

Box 2: FORCESEEK

FORCESEEK [ (index_value(index_column_name [ ,… n ] )) ] Specifies that the query optimizer use only an index seek operation as the access path to the data in the table or view.

When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back.

Correct Answer:

Explanation:

NULL or NOT NULL specifies whether the column can accept null values. Columns that do not allow null values can be added with ALTER TABLE only if they have a default specified or if the table is empty. NOT NULL can be specified for computed columns only if PERSISTED is also specified. If the new column allows null values and no default is specified, the new column contains a null value for each row in the table. If the new column allows null values and a default definition is added with the new column, WITH VALUES can be used to store the default value in the new column for each existing row in the table.

Which isolation levels should you use? To answer, drag the appropriate isolation levels to correct stored procedures. Each isolation level 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.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: READ_COMMITTED

READ COMMITTED specifies that statements cannot read data that has been modified but not committed by other transactions. This prevents dirty reads. Data can be changed by other transactions between individual statements within the current transaction, resulting in nonrepeatable reads or phantom data. This option is the SQL Server default.

The behavior of READ COMMITTED depends on the setting of the READ_COMMITTED_SNAPSHOT database option

Box 2: REPEATABLE_READ:

REPEATABLE_READ specifies that statements cannot read data that has been modified but not yet committed by other transactions and that no other transactions can modify data that has been read by the current transaction until the current transaction completes.

Shared locks are placed on all data read by each statement in the transaction and are held until the transaction completes. This prevents other transactions from modifying any rows that have been read by the current transaction.

Box 3: SERIALIZABLE

SERIALIZABLE Specifies the following:

Statements cannot read data that has been modified but not yet committed by other transactions. No other transactions can modify data that has been read by the current transaction until the current transaction completes. Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.
