You have a database that contains tables named Customer_CRMSystem and Customer_HRSystem. Both tables use the following structure:

The following records exist in the tables:
Customer_CRMSystem

Customer_HRSystem

Records that contain null values for CustomerCode can be uniquely identified by CustomerName.
You need to display distinct customers that appear in both tables.

DRAG DROP
You need to create a stored procedure that meets the following requirements:
*Produces a warning if the credit limit parameter is greater than 7,000
*Propagates all unexpected errors to the calling process
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQP segments to the correct locations. Each Transact-SQL segments 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: THROW 51000, 'Warning: Credit limit is over 7,000!",1
THROW raises an exception and transfers execution to a CATCH block of a TRY...CATCH construct in SQL Server.
THROW syntax:
THROW [ { error_number | @local_variable },
{ message | @local_variable },
{ state | @local_variable } ]
[ ; ]
Box 2: RAISERROR (@ErrorMessage, 16,1)
RAISERROR generates an error message and initiates error processing for the session.
RAISERROR can either reference a user-defined message stored in the sys.messages catalog view or build a message dynamically. The message is returned as a server error message to the calling application or to an associated CATCH block of a TRY...CATCH construct. New applications should use THROW instead.
Severity levels from 0 through 18 can be specified by any user. Severity levels from 19 through 25 can only be specified by members of the sysadmin fixed server role or users with ALTER TRACE permissions. For severity levels from 19 through 25, the WITH LOG option is required.
On Severity level 16. Using THROW to raise an exception
The following example shows how to use the THROW statement to raise an exception.
Transact-SQL
THROW 51000, 'The record does not exist.', 1;
Here is the result set.
Msg 51000, Level 16, State 1, Line 1
The record does not exist.
Note: RAISERROR syntax:
RAISERROR ( { msg_id | msg_str | @local_variable }
{ ,severity ,state }
[ ,argument [ ,...n ] ] )
[ WITH option [ ,...n ] ]
Note: The ERROR_MESSAGE function returns the message text of the error that caused the CATCH block of a TRY...CATCH construct to be run.

HOTSPOT
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:


You need to identify the owner of each task by using the following rules:
- Return each task's owner if the task has an owner.
- If a task has no owner, but is associated with a project that has an owner, return the project's owner.
- Return the value -1 for all other cases.
How should you complete the Transact-SQL statement? To answer, select the appropriate
Transact-SQL segments in the answer area.

Correct Answer:

Explanation:

Box 1: COALESCE
COALESCE evaluates the arguments in order and returns the current value of the first expression that initially does not evaluate to NULL.
Box 2: T.UserID, p.UserID, -1
- Return each task's owner if the task has an owner.
- If a task has no owner, but is associated with a project that has an owner, return the project's owner.
- Return the value -1 for all other cases.
Box 3: RIGHT JOIN
The RIGHT JOIN keyword returns all rows from the right table (table2), with the matching rows in the left table (table1). The result is NULL in the left side when there is no match.
Here the right side could be NULL as the projectID of the task could be NULL.
