Types of Cursor in MSSQL

SQL Server Different Types of Cursors

           

A Cursor allow us to retrieve data from a result set in singleton fashion means row by row. Cursor are required when we need to update records in a database table one row at a time. I have already explained the basic of cursor.

A Cursor impacts the performance of the SQL Server since it uses the SQL Server instances' memory, reduce concurrency, decrease network bandwidth and lock resources. Hence it is mandatory to understand the cursor types and its functions so that you can use suitable cursor according to your needs.
You should avoid the use of cursor. Basically you should use cursor alternatives like as WHILE loop, sub queries, Temporary tables and Table variables. We should use cursor in that case when there is no option except cursor.

Windows Installer Setup With Custom Actions

Install Window Service Programmitcally

You can do it all in one executable. To pass installation parameters, you will need to derive classes System.ServiceProcess.ServiceProcessInstaller and System.ServiceProcess.ServiceInstaller. You only need to implement constructors of your classes.

Installation and uninstallation will be done by System.Configuration.Install.AssemblyInstaller. This class should use the assembly where the classes based on ServiceProcessInstaller and ServiceInstaller are implemented; the implementation will be found in your assembly automatically (which would create a hard-to-detect failure if you have a bug in the implementation). Not too bad though.

Finally, start/stop, etc. are handled by your service code which you create deriving the class System.ServiceProcess.ServiceBase. Triggering this actions is done by Service Controller. To do it programmatically you should use the class System.ServiceProcess.ServiceController.

You need to have a good reading of MSDN on the topics around the classes I listed above, which is well illustrated by code samples. This information is easy to find, a bit harder to understand the work flow and what happens in which process. (A Windows Service process is always a separate one; it takes another process to run installation and Service Controller part.) You can use all this like a cookbook, but I suggest you thoroughly understand it; in this case you won't have any problems.

You can even try to implement it all in one application as I did, but you still need to run it in at least two different processes: one would work in the Windows Service mode, another is must be interactive mode, which can be anything else, such as UI, Console or just invisible batch-mode application.

Important! You code can test System.Environment.UserInteractive during run time to calculate is currently running code is run as Windows Service or not.

Add Installer for Window Service

In the service project do the following:

1. In the solution explorer double click your services .cs file. It should bring up a screen that is all gray and talks about dragging stuff from the toolbox.
2. Then right click on the gray area and select add installer. This will add an installer project file to your project.
3. Then you will have 2 components on the design view of the ProjectInstaller.cs (serviceProcessInstaller1 and serviceInstaller1). You should then setup the properties as you need such as service name and user that it should run as.
