Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

SHOW ENGINE INNODB STATUS

The command 'SHOW ENGINE INNODB STATUS' provides a section specifically detailing the last detected deadlock, including the locks held by the involved transactions.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • CHECK TABLE

    Why it's wrong here

    CHECK TABLE identifies corruption in tables, not transaction deadlocks.

  • SHOW ENGINE INNODB STATUS

    Why this is correct

    This command outputs the InnoDB monitor output, which includes the latest deadlock detection information.

  • EXPLAIN

    Why it's wrong here

    EXPLAIN is used for query execution plan analysis, not deadlock diagnostics.

  • SHOW PROCESSLIST

    Why it's wrong here

    This shows active connections but not the specific lock structures involved in deadlocks.
