How to escape apostrophe (') in MySql?

Question

The MySQL documentation says that it should be \\\'. However, both scite and mysql shows that \'\' works. I saw that and it works. What should I d

Answer 1

Possibly off-topic, but maybe you came here looking for a way to sanitise text input from an HTML form, so that when a user inputs the apostrophe character, it doesn't throw an error when you try to write the text to a SQL-based table in a DB. There are a couple of ways to do this, and you might want to read about SQL injection too, but a simple option in PHP is to use the htmlspecialchars() function which will convert all your apostrophes into ' which is possibly what you want to store anyway.

Answer 2

In PHP I like using mysqli_real_escape_string() which escapes special characters in a string for use in an SQL statement.

see https://www.php.net/manual/en/mysqli.real-escape-string.php

Answer 3

Replace the string

value = value.replace(/'/g, "\\'");

where value is your string which is going to store in your Database.

Further,

NPM package for this, you can have look into it

Answer 4

There are three ways I am aware of. The first not being the prettiest and the second being the common way in most programming languages:

1. Use another single quote: 'I mustn''t sin!'
2. Use the escape character \ before the single quote': 'I mustn\'t sin!'
3. Use double quotes to enclose string instead of single quotes: "I mustn't sin!"
