Sql validating data against data type
The original purpose of the code was to create an SQL statement to select a user, with a given user id.
If there is nothing to prevent a user from entering "wrong" input, the user can enter some "smart" input like this: User Id: The SQL above is valid and will return ALL rows from the "Users" table, since OR 1=1 is always TRUE. What if the "Users" table contains names and passwords?
The Vixen Blog Awards, which took place a few of months ago, is pretty much the highlight of the year for most Norwegians. Lately, it seems not a day goes by without one or several of our treasured fitness, lifestyle, fashion or furniture bloggers being front and center in some newspaper or magazine with hot off the press social commentary.
Common topics include how to oppose the use of palm oil while still using palm oil, making food with zero calories, “janteloven”, flashing of various body parts, and of course how to not care about the looks of said body parts because you’re pretty just the way you are.
Still, what if I wanted to get back into that kind of blogging?
I can’t help but wonder which blogger I have the most in common with now and which blog award I’ve got the biggest chance of winning next year if I stop writing about tech stuff and start writing about everything else. Go to the Vixen Blog Awards, Machine Learning Edition web service, enter any NORWEGIAN block of text of any size, and press the submit button.
The annual Vixen Blog Awards is an opportunity to reap the rewards from these endeavours from the last twelve months.

Look at the following example which creates a SELECT statement by adding a variable (txt User Id) to a select string.
The variable is fetched from user input (get Request String): Look at the example above again.
