PHP MySQL查询打印

Question

Is there anyway I can see a query once it has been run and all variables have been instantiated?

eg I want to see the end result (String) of

$query = $this->db->query("SELECT email, password FROM users
    WHERE email = '$email' AND password = 'PASSWORD($password)'");

I would like to see the query string after PASSWORD($password) has been done.

Answer 1

查询字符串在MySql中不会更改，但是您可以执行以下操作以查看密码：

$query = $this->db->query("SELECT PASSWORD('".mysql_real_escape_string($password)."')");

Answer 2

You can store the string as a variable before hand.

eg)

$query = "SELECT email, password FROM users
    WHERE email = '$email' AND password = 'PASSWORD($password)'";

and then output the query with var_dump($query) .

$this->db->query($query);

It is better practice though to use prepared statements and feed in escaped variables.

Answer 3

I needed to change 'PASSWORD($password)'

to:

PASSWORD('$password')

This fixed my issue.
