[support] sanitizing text box input for sql searches (custom search)

[spartaguy spartaguy]

Hello,

I want to use the data from a textbox input to do a select statement on a
sql db.

 Are there any inbuilt methods that drupal uses to sanitize textbox inputs?
I'm worried if I accept data in a textbox and apply it to an sql command it
will do bad stuff (tm).

Is there a simple code snippet or module for sanitizing?
