Observe that suitable output encoding, escaping, and quoting is the simplest Remedy for avoiding SQL injection, While input validation may give some defense-in-depth. It's because it properly restrictions what is going to surface in output. Input validation will likely not always avert SQL injection, especially if you happen to be required to assist absolutely free-sort textual content fields that can include arbitrary characters. By way of example, the identify "O'Reilly" would probable move the validation phase, since it is a typical last title within the English language. However, it cannot be directly inserted to the databases since it includes the "'" apostrophe character, which might need to be escaped or in any other case handled. In such a case, stripping the apostrophe may possibly reduce the risk of SQL injection, but it could generate incorrect habits because the Completely wrong name might be recorded. When possible, it could be safest to disallow meta-people fully, in lieu of escaping them. This can give some defense in depth. Once the info is entered in to the databases, later on processes may neglect to flee meta-characters right before use, and you may not have Handle around All those procedures.
