ASP and MySQL Escape Character Help

MySQL for Dummies (or dumb MS developers...)

About two months ago I converted a classic ASP web site from using SQL Server to MySQL. I could write a book with what I've learned, but I still have so much I can't figure out.

I've had my asp code snippets that protect against SQL injection attacks for years, but they don't work for MySQL!

I guess I'm just thick-headed, but I just can't figure out how to escape bad characters out of a SQL statement.

I've tried 'Replace(Value, "'", "\'")' which works ok I think, except for when the Value already containts \', which it turns to \\' and then MySQL can't process it.

There's got to be other MS developers that have this figured out, but I haven't been able to find any. Because of the size of the conversion, I have to use concatenated strings.

Please help!

If there's no valid reason for a user to ever give you a string that has \' in it, then the simplest solution is to strip all occurrences of \' before you try to escape the string.
