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


Task level is defined using the following rules:

You need to determine the task level for each task in the hierarchy.
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.

Answer:

Explanation: Box 1: SELECT CAST (NULL AS INT) AS ParentTaskID, etc.
This statement selects all tasks with task level 0.
The ParentTaskID could be null so we should use CAST (NULL AS INT) AS ParentTaskID. Box 2: UNION
We should use UNION and not UNION ALL as we do not went duplicate rows.
UNION specifies that multiple result sets are to be combined and returned as a single result set.
Incorrect: Not UNION ALL: ALL incorporates all rows into the results. This includes duplicates. If not specified, duplicate rows are removed.
Box 3, Box 4, Box 5:
These statements select all tasks with task level >0. References:

You have a table named AuditTrail that tracks modifications to data in other tables. The AuditTrail table is updated by many processes. Data input into AuditTrail may contain improperly formatted date time values. You implement a process that retrieves data from the various columns in AuditTrail, but sometimes the process throws an error when it is unable to convert the data into valid date time values.
You need to convert the data into a valid date time value using the en-US format culture code. If the conversion fails, a null value must be returned in the column output. The conversion process must not throw 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: A TRY_CONVERT function returns a value cast to the specified data type if the cast succeeds; otherwise, returns null.
