A CASE expression returns a single value that is conditionally evaluated for each row of a table (or view). Use the WHEN-THEN clauses when you want to execute a CASE expression for some but not all of the rows in the table that is being queried or created. An optional ELSE expression gives an alternative action if no THEN expression is executed We could change that to CS for case-sensitive, and AS for accent-sensitive, and the query results may be sorted differently (depending on the data): USE Music; SELECT ArtistId, ArtistName FROM Artists ORDER BY ArtistName COLLATE Latin1_General_CS_AS; So, this allows you to override the collation that's applied at the database or column level when running a query.

For example, imagine you have a table with employee information that contains a char(1) field called Gender, with a value of M for males and F for females

To avoid this situation, usually, developers add T-SQL If Exists statement and drop the object if it is already available in the database. Let's say we wish to deploy a stored procedure 'stpGetAllMembers' in the SQLShack test database. We can use multiple methods to check whether the procedure existence in the SQL database but let's query sys.objects system table for it. The following. In this case the results of the subquery would be used on one side of a WHERE clause condition. Here is an example: I can then use this alias elsewhere in the T-SQL statement to refer to the columns from the subquery by prefixing them with an a, as I did in the ON clause of the JOIN criteria. Sometimes using a subquery in the FROM clause reduces the size of the set that needs to be. CASE expressions bring a vast degree of power and control to SQL Server programmers. A working knowledge of CASE expressions can make accessing and updating SQL Server data easier and perhaps, even more efficient. Additionally, CASE expressions enable more work to be accomplished using a single SQL statement, which should also improve efficiency and decrease development time. As such, CASE. p>Note that the above T-SQL command will restore the full backup completely and bring the database online.
