You work for an organization that monitors seismic activity around volcanos. You have a table named GroundSensors. The table stored data collected from seismic sensors. It includes the columns describes in the following table:

The database also contains a scalar value function named NearestMountain that returns the name of the mountain that is nearest to the sensor.
You need to create a query that shows the average of the normalized readings from the sensors for each mountain. The query must meet the following requirements:
Include the average normalized readings and nearest mountain name.

Exclude sensors for which no normalized reading exists.

Exclude those sensors with value of zero for tremor.

Construct the query using the following guidelines:
Use one part names to reference tables, columns and functions.

Do not use parentheses unless required.

Do not use aliases for column names and table names.

Do not surround object names with square brackets.

Answer: 
See the solution below
Explanation/Reference:
SELECT Average(NormalizedReading), NearestMountain(SensorID)
FROM GroundSensors
GROUP BY NearestMountain(SensorID)
WHERE TREMOR IS NOT 0 AND NormalizedReading IS NOT NULL
Explanation:
GROUP BY is a SELECT statement clause that divides the query result into groups of rows, usually for the purpose of performing one or more aggregations on each group. The SELECT statement returns one row per group.

Answer: G
Explanation/Reference:
Explanation:
A cross join that does not have a WHERE clause produces the Cartesian product of the tables involved in the join. The size of a Cartesian product result set is the number of rows in the first table multiplied by the number of rows in the second table.

Multiple processes use the data from a table named Sales and place it in other databases across the organization. Some of the processes are not completely aware of the data types in the Sales table. This leads to data type conversion errors.
You need to implement a method that returns a NULL value id data conversion fails instead of throwing an error.
What should you implement?
A. the COALESCE function
B. a view
C. a table-valued function
D. the TRY_PARSE function
E. a stored procedure
F. the ISNULL function
G. a scalar function
H. the TRY_CONVERT function
Answer: H
Explanation/Reference:
Explanation:
TRY_CONVERT returns a value cast to the specified data type if the cast succeeds; otherwise, returns null.

You are creating a report to show when the first customer account was opened in each city. The report contains a line chart with the following characteristics:
The chart contains a data point for each city, with lines connecting the points.

The X axis contains the position that the city occupies relative to other cities.

The Y axis contains the date that the first account in any city was opened.

An example chart is shown below for five cities:

During a sales promotion, customers from various cities open new accounts on the same date.

Explanation:
Box 1: RANK() OVER
RANK returns the rank of each row within the partition of a result set. The rank of a row is one plus thenumber of ranks that come before the row in question.
ROW_NUMBER and RANK are similar. ROW_NUMBER numbers all rows sequentially (for example 1, 2,
3, 4, 5).
Incorrect Answers:
DENSE_RANK returns the rank of rows within the partition of a result set, without any gaps in the ranking.
The rank of a row is one plus the number of distinct ranks that come before the row in question.
Box 2: (PARTITION BY CityID ORDER BY MIN(AccountOpenedDate) DESC)
Syntax for RANK: RANK ( ) OVER ( [ partition_by_clause ] order_by_clause ) Box 3: GROUP BY CityID References: https://msdn.microsoft.com/en-us/library/ms176102.aspx

Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?
A. Yes
B. No
Answer: B
Explanation/Reference:
Explanation:
With X_ABORT ON the INSERT INTO statement and the transaction will be rolled back when an error is raised, it would then not be possible to ROLLBACK it again in the IF XACT_STATE() <> O ROLLACK TRANSACTION statement.
Note: A transaction is correctly defined for the INSERT INTO ..VALUES statement, and if there is an error in the transaction it will be caughtant he transaction will be rolled back, finally an error 51000 will be raised.
Note: When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back.
XACT_STATE is a scalar function thatreports the user transaction state of a current running request.
XACT_STATE indicates whether the request has an active user transaction, and whether the transaction is capable of being committed.
The states of XACT_STATE are:
0 There is no active user transaction for the current request.

1 The current request has an active user transaction. The request can perform any actions, including

writing data and committing the transaction.
2 The current request has an active user transaction, but an error hasoccurred that has caused the

transaction to be classified as an uncommittable transaction.

ISNULL Syntax: ISNULL ( check_expression , replacement_value ) author:"Luxemburg, Rosa" The ISNULL function replaces NULL with the specified replacement value. The value of check_expression is returned if it is not NULL; otherwise, replacement_value is returned after it is implicitly converted to the type of check_expression.
