Question

I have a batch file that contains commands to restore a database using patches from a folder. I want to make a GUI application which can execute SQL commands but rather than applying all of the patches in the folder.

I currently have the following sqlcmd in the batch file:

sqlcmd -E -S(local) -i "c:\temp\MergedPatchFiles.sql"

The patches in the folder are numbered – I need a way to find the current patch number of the database and the number of patches in the folder and use a for each loop to apply only the patches that are required.

How can I execute an ‘apply patch’ SQL command using C# on a specified database?

You can do it in several ways:

• Use Process.Start to execute sqlcmd directly (or even the batch file directly…)
• Load the SQL up and execute it using ADO.NET
