Account Unlock

ALTER USER 'asha'@'localhost' ACCOUNT UNLOCK; allows login again after a lock or after password policy lockout (depending on version/settings).

If login still fails, the password or host ('asha'@'%') may be wrong — unlock is not a password reset.

Trap — UNLOCK and assuming the password is the one you remember from last year.

On the example next to this theory: Account Unlock: create two demo rows, then SELECT qty >= 2 ordered. Say which labels come back.

Exam tip

ALTER USER 'asha'@'localhost' ACCOUNT UNLOCK;

Account Unlock — sample query

-- Account Unlock
CREATE TABLE demo (
  id INTEGER PRIMARY KEY,
  label TEXT NOT NULL,
  qty INTEGER DEFAULT 0
);
INSERT INTO demo (id, label, qty) VALUES
  (1, 'alpha', 2),
  (2, 'beta', 5);
SELECT label, qty FROM demo WHERE qty >= 2 ORDER BY qty DESC;

Account Unlock: create two demo rows, then SELECT qty >= 2 ordered. Say which labels come back.

Short notes

DefACCOUNT UNLOCK re-enables a locked user.
RuleStill need the correct password and host.
TrapUnlock ≠ reset password.

-- Account Unlock CREATE TABLE demo ( id INTEGER PRIMARY KEY, label TEXT NOT NULL, qty INTEGER DEFAULT 0 ); INSERT INTO demo (id, label, qty) VALUES (1, 'alpha', 2), (2, 'beta', 5); SELECT label, qty FROM demo WHERE qty >= 2 ORDER BY qty DESC;
