Defining the Header Information for Our Script

Once again, we have general header information for our script (see Listing 1), but I am sure you know what all this code means by now. Just make sure that any comments or specific company information is held within the header for other script writers later on.

Listing 1—Header Information for Our SP2 Script.

REM *********************************************************************************************

Although this header info looks very similar to the installation of SQL Server script (InstallSQLServer.bat), there are a number of parameters specified in the installation script that we don't need to specify in the SP update script. Why? Well, we don't actually need all of the parameters that we would use when installing SQL Server; for example, we don't need the port number that SQL Server listens on.


In our earlier script, InstallSQLServer.bat, we specified a number of parameters that by default are not necessarily required to specify. Although you can edit your script so you do not need to provide as many parameters, I did this explicitly so that the scripts that we write are more easily adapted to your specific needs. Otherwise, you need to accept the defaults of the installation program of SQL Server.
