    The most common SQL coding interview questions are listed in Matthew Urban’s book ” TOP 30 SQL Interview Coding Tasks”. Less than 100 pages include deeply-explained, most commonly used data manipulation queries, relationships modeling, aggregation, sorting, table joins, index and other top topics to discuss during the job interview. Very well written book.

    OK… a few extra questions to ask/include on MySQL interview: (especially notable for DBA/admin)

    (1) Show the total amount of storage being used by each database under MySQL… organized by owner.
    (2) List the indexes for all tables in database “Sales”… and show me any tables which do not have indexes.
    (3) If MySQL database service is Not running, where do you look for problems/errors to correct.
    (4) If MySQL is not running, how do you find disk storage used by MySQL …storage FREE/avail for MySQL?
    (5) List all active connections to running MySQL DB… and what can you know about activity…
    (6) Discuss steps to move/copy a MySQL database from ServerA to ServerB ?
    (7) Comment on setup of ServerJ and ServerK for load balancing & fail-over operation, so BOTH stay updated?
    (8) Describe steps to backup or restore data/tables/index for database “blue” with other databases still running?
