You are building a stored procedure named SP1 that calls a stored procedure named SP2.
SP2 calls another stored procedure named SP3 that returns a Recordset. The Recordset is stored in a temporary table.
You need to ensure that SP2 returns a text value to SP1.
What should you do?

• A.Create a temporary table in SP2, and then insert the text value into the table.
• B.Return the text value by using the ReturnValue when SP2 is called.
• C.Create a table variable in SP2, and then insert the text value into the table.
• D.Add the txt value to an OUTPUT parameter of SP2.

You need to develop a Transact-SQL statement that meets the following requirements:
- The statement must return a custom error when there are problems updating a table.
- The error number must be value 50555.
- The error severity level must be 14.
- A Microsoft SQL Server alert must be triggered when the error condition occurs.
Which Transact-SQL segment should you use for each requirement? To answer, select the appropriate Transact-SQL segments in the answer area.

Explanation

Box 1: TRY...CATCH
The TRY...CATCH Transact-SQL construct implements error handling for Transact-SQL that is similar to the exception handling in the Microsoft Visual C# and Microsoft Visual C++ languages. A group of Transact-SQL statements can be enclosed in a TRY block. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.
Box 2: RAISERROR(50555, 14, 1 'The update failed.") WITH LOG
We must use RAISERROR to be able to specify the required severity level of 14, and we should also use the LOG option, which Logs the error in the error log and the application log for the instance of the Microsoft SQL Server Database Engine, as this enable a MS MS SQL SERVER alert to be triggered.
Note: 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.

You have a table named HumanResources.Employee. You configure the table to use a default history table that contains 10 years of data.

Explanation

Wildcard character %: Any string of zero or more characters.
For example: If the LIKE '5%' symbol is specified, the Database Engine searches for the number 5 followed by any string of zero or more characters.
