Question

There is a query

UPDATE users SET hash =: hash, num_try_incorrect_pass = 0 
WHERE email =: email; SELECT * FROM users WHERE email =: email

First perform UPDATE
Next SELECT

How to do this with one request?

Answer 1

How about using stored procedures? If you are looking for execute both queries from one code-statement you can define them as stored procedure in your database.

DELIMITER //
CREATE PROCEDURE ExecuteQueries(IN pEmail VARCHAR(50),
                    IN pHash VARCHAR(60))
  BEGIN
    UPDATE users SET hash=pHash, num_try_incorrect_pass = 0 WHERE email = pEmail;
    SELECT * FROM users WHERE email = pEmail;
  END //
DELIMITER ;

You can then execute both of these statements though your php code in this manner:

$stmt = $dbh->prepare("CALL ExecuteQueries($sEmail,$sHash)");
