Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: A

If the INSERT INTO statement raises an error, the statement will be caught and an error 51000 will be thrown. In this case no records will have been inserted.

Note:

You can implement error handling for the INSERT statement by specifying the statement in a TRY…CATCH construct.

If an INSERT statement violates a constraint or rule, or if it has a value incompatible with the data type of the column, the statement fails and an error message is returned.

DRAG DROP

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is

exactly the same in each question in this series.

You query a database that includes two tables: Project and Task. The Project table includes the following columns:

When running an operation, you updated a column named EndTime for several records in the Project table, but updates to the corresponding task records in the Task table failed.

You need to synchronize the value of the EndTime column in the Task table with the value of the EndTime column in the project table. The solution must meet the following requirements:

If the EndTime column has a value, make no changes to the record.

If the value of the EndTime column is null and the corresponding project record is marked as completed, update the record with the project finish time.

Which four 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.

Select and Place:

Correct Answer:

Box 1: UPDATE T SET T.EndTime = P.EndTime

We are updating the EndTime column in the Task table.

Box 2: FROM Task AS T

Where are updating the task table.

Box 3:INNER JOIN Project AS P on T.ProjectID = P.ProjectID

We join with the Project table (on the ProjectID columnID column).

Box 4: WHERE P.EndTime is NOT NULL AND T.EndTime is NULL

We select the columns in the Task Table where the EndTime column in the Project table has a value (NOT NULL),but where it is NULL in the Task Table.

The script must update the value of the IsDeleted column of the Employee table to 1 if the value of the Id column is equal to 1 for the Employee table when an update to the UserLogin table throws an error. The error message “No tables updated!” must be produced when an update to the Employee table throws an error.

Which five 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.
