Hmm, don't have experience with ASP, so don't know the syntax, but I'll try to explain what you need to do.
the 'request.querystring("playerID")' sounds pretty logical to me, I assume that's the code to request the part from the querystring (GET and POST vars) that's tagged 'playerID'.
Then you need to parse it into the SQL query. Again, I don't know the ASP syntax for string concatenation, but I believe it's the ampersand (&):
Your current code will be something like this:
Code:
SQLquery = "SELECT * FROM mydatabase where playerID = 'player1'";
change it to something like this
Code:
SQLquery = "SELECT * FROM mydatabase where playerID = '" & request.querystring("playerID") & "'";
Again, I'm not proficient in ASP, so I hope this is useful.
