This time, however, I ve added an Action column that determines the action to take when a row is matched. If the Action is Delete, matched rows are deleted from the target table. If the Action is Update (or anything else for that matter), matched rows will be updated. CREATE TABLE #TempShifts ( Name varchar(50) NOT NULL, StartTime time NOT NULL, EndTime time NOT NULL, Action varchar(10) NOT NULL ); GO INSERT INTO #TempShifts (Name, StartTime, EndTime, Action) VALUES ('Morning Part-time', '08:00:00', '12:00:00', 'DELETE'), ('Evening Part-time ', '18:00:00', '22:00:00', 'UPDATE'), ('Midnight Swing Shift', '00:00:00', '04:00:00', 'DELETE'); The MERGE statement begins as before, the only difference being that the Action column is also returned by the USING source table: MERGE HumanResources.Shift AS target USING #TempShifts AS source winforms barcode scanner distinguish bewteen keyboard keydown and barcode keydown - CodeProject

There are now two WHEN MATCHED clauses in the MERGE statement. The first performs a DELETE when the row is matched and the source row Action is Delete. Notice that the DELETE clause is like a thoroughly abbreviated DELETE statement. Unlike the DELETE statement, you don t need to specify a table to delete from, since the target table was already specified at the beginning of the MERGE statement. You also don t need to use a WHERE clause to restrict the rows, since it only deletes the current matched row. WHEN MATCHED AND (source.Action = 'Delete') THEN DELETE The second WHEN MATCHED clause captures every matching row that falls through the first WHEN MATCHED clause. It doesn t need an AND clause. WHEN MATCHED THEN UPDATE SET Name = source.Name, StartTime = source.StartTime, EndTime = source.EndTime Finally, the WHEN TARGET NOT MATCHED clause captures and inserts all source rows that don t match the target table: WHEN TARGET NOT MATCHED THEN INSERT ( Name, StartTime, EndTime ) VALUES ( source.Name, source.StartTime, source.EndTime ); The results of this MERGE statement example are that the Morning Part-time and Midnight Swing Shift work shifts are deleted. The Evening Part-time shift is updated so that its new StartTime and EndTime are 16:00:00 and 20:00:00, respectively. The results are shown in Figure 2-4. winforms barcode reader distinguishing barcode scanners from the keyboard in winforms ...

This would allow you to delegate control over user objects within a given OU, for example, but no other resources. Once you ve selected the object types, you ll finish by selecting the specific ACL permissions that should be delegated, ranging from full control down to permissions over specific attributes of different objects, as you can see in Figure 3-1. The MERGE statement may offer code simplification and performance benefits over other methods of performing the same type of conditional updates, inserts, and deletes. I ve actually seen production ETL (extract, transform, load) systems and client-side solutions that resort to performing individual SELECT queries against a table for every row to be inserted, just to determine if the target table contains a match. The client-side solution then decides whether to send a single UPDATE, INSERT, or DELETE statement for each row. For 1,000,000 rows being imported, you re suddenly looking at 2,000,000 total separate SQL statements and 2,000,000 round trips to the server! It s a horrible solution, at best, and often the bottleneck in an otherwise decent ETL process. A proper MERGE statement solution has the potential to eliminate a lot of the pain and performance problems inherent in many custom ETL solutions. The MERGE statement is poised to figure prominently in both object/relational (O/R) systems for transactional databases and ETL solutions for data warehouses and data marts. In both cases, the MERGE statement may be able to offer both code simplification and potential performance benefits over other common methods of performing conditional row updates, inserts, and deletes. When you are planning your backup, it helps to have the operating system and the data separated. The operating system should rarely change. Because the operating system is so static, you can use a simplistic backup scheme for it. In this example, we re going to look at leveraging Time Machine for this very purpose. winforms barcode scanner distinguishing barcode scanners from the keyboard in winforms ...
