HOW CAN I USE VALIDATION CODES IN ORDER TO AVOID SQL INJECTION IN MY WEB SERVER? I MEAN, EVERYBODY KNOW THAT HTML MODIFICATION IS VERY EASY, SO, DO I HAVE TO USE WEB SERVICES TO DO THIS OR GET ANOTHER APP?
I have accidentally updated all data in a SQL Server table according to one data source, and now all my data is a copy of that data. How can I make a command to allow all data in that table to search for other data and update, according to another reference table?
