How do I include multiple parameters in a SQL query in C#.net?
I have a form that I accept inputs from 5 text boxes.
I want to be able to include each input from the text boxes in my insert into query.
I want to use parameters to prevent database injection.
I also want to update the field in the database as NULL if nothing was entered in a text box.
I am using a SQL backend.
Could you please show me a working coded example of how to this?
