Increase a value like = +1 in mysql and PHP

Question

I need help with this.

I am making a login and when a user insert a bad answer i want that my system take the valor of the column in the database and this adds the value of the base + 1

I try making this

$sql2 = "UPDATE usuarios_empleados  set intentos = + 1 where usuario = ?";
$params2 = array ($this->nickname);
return Database::executeRow($sql2, $params2);

Answer 1

请尝试此行，希望它能工作

"UPDATE usuarios_empleados SET intentos = intentos + 1 where id_usuario_empleado = your_value"

Answer 2

更新usuarios_empleados设置intentos =（intentos +1）其中usuario =吗？

Answer 3

You have to first make a SELECT and see the value of the column "intentos". Then you will do the UPDATE using the value from the SELECT + 1
