How do I escape % in Knex where like query?

Question

I\'m using knex to generate my SQL queries. In knex documentation, it shows this

knex(\'users\').where(\'columnName\', \'like\', \'

Knex doesn't have an equivalent to the ESCAPE keyword [1], so you have to do a raw query like this, which will search for users with name === "%foo%":

knex.raw('select * from users where name like ? escape \', ['\%foo\%'])

And this, with an unescaped wildcard at the beginning of the search term, will search for users with name ending in "%foo%":

knex.raw('select * from users where name like ? escape \', ['%\%foo\%'])
