Oracle MySQL Implementation Associate Exam Practice Test

The Oracle MySQL Implementation Associate Exam (1Z0-922) practice page focuses on foundational MySQL database implementation and use. The available questions sample SQL statements, column types, transactions, account privileges, and basic database maintenance. These topics involve recognizing how MySQL stores values, changes data, controls access, and handles common schema and backup tasks.

About the Oracle MySQL Implementation Associate Exam

Implementation work requires matching database structures and operations to application needs. Practice interpreting column definitions such as `DATE` and `AUTO_INCREMENT`, and distinguishing aggregate queries from statements that change schema or data. Transaction questions test when an explicit transaction begins and how `ROLLBACK` affects uncommitted work. Access-control items ask you to reason about account privileges, including granting `SELECT` on a database object and removing assigned privileges. Other prompts address selecting the active database, dropping a table, and why administrators preserve backups. Build accuracy by identifying each statement’s scope and effect before choosing an answer, especially when similar commands have different consequences for data, definitions, or access.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

Which MySQL data type is designed to store a calendar date without a time of day?

  1. ADATE
  2. BTIME
  3. CYEAR
  4. DDATETIME
Show answerCorrect answer: A

`DATE` stores a calendar date. `TIME` stores a time value, `YEAR` stores a year, and `DATETIME` stores both date and time components.

Question 2

What is the usual effect of running `ROLLBACK` during a transaction that has not been committed?

  1. AIt makes the transaction’s changes permanent.
  2. BIt discards the transaction’s uncommitted changes.
  3. CIt creates a savepoint before the next statement.
  4. DIt closes the MySQL server.
Show answerCorrect answer: B

For a transactional storage engine, `ROLLBACK` undoes changes made in the current uncommitted transaction. It does not undo changes that have already been committed.

Question 3

Which MySQL statement begins an explicit transaction for a session?

  1. ASTART TRANSACTION;
  2. BCREATE TRANSACTION;
  3. COPEN TRANSACTION;
  4. DBEGIN TABLE;
Show answerCorrect answer: A

`START TRANSACTION` begins an explicit transaction. `BEGIN` is also accepted as a transaction-start synonym in MySQL, but the other choices are not the appropriate syntax.

Question 4

In MySQL, what does the `AUTO_INCREMENT` attribute do for an integer column?

  1. AAutomatically assigns a new value when a row is inserted without an explicit value for that column
  2. BIncreases the column’s maximum permitted value after each update
  3. CCopies the value from the preceding row
  4. DResets the column to zero whenever the table is queried
Show answerCorrect answer: A

An `AUTO_INCREMENT` column generates a successive value for an inserted row when the insert does not supply a value for that column. It is commonly used for surrogate identifiers.

Question 5

Why might a database administrator create a regular backup of a MySQL database?

  1. ATo support recovery after data loss or corruption
  2. BTo make every query execute without indexes
  3. CTo prevent users with privileges from changing data
  4. DTo automatically normalize all tables
Show answerCorrect answer: A

Backups provide a recoverable copy of data and are an important part of planning for failures, accidental changes, or corruption.

Question 6

Which aggregate function returns the largest value in a numeric column named `score`?

  1. ATOP(score)
  2. BHIGH(score)
  3. CMAX(score)
  4. DUPPER(score)
Show answerCorrect answer: C

`MAX(score)` returns the greatest value found in the expression's input rows. It is commonly used as an aggregate function, including within grouped queries.

Question 7

Which MySQL statement grants the `SELECT` privilege on `sales.*` to the account `'reporter'@'localhost'`?

  1. AGRANT SELECT ON sales.* TO 'reporter'@'localhost';
  2. BALLOW SELECT ON sales.* FOR 'reporter'@'localhost';
  3. CSET PRIVILEGE SELECT IN sales.* TO 'reporter'@'localhost';
  4. DCREATE GRANT SELECT sales.* USER 'reporter'@'localhost';
Show answerCorrect answer: A

MySQL uses `GRANT privilege ON object TO account` syntax to assign privileges. Here, `sales.*` denotes all tables in the `sales` database.

How to use this practice test

Access is free. When questions are published for this exam, a session presents up to 20 randomly selected items from the 50-question practice bank and shows your results afterward. Use the result review to identify missed concepts, then revisit the relevant MySQL syntax and operational behavior before another session.

Preparation tips

  • For transaction questions, distinguish starting an explicit transaction, committing changes, and rolling back uncommitted work.
  • Practice mapping column requirements to MySQL types and attributes, including date-only values and automatically generated integer values.
  • Write sample `GRANT` and privilege-removal statements; check the account host and the database or table scope each statement targets.
  • Compare the effects of `DROP TABLE`, selecting the current database, and aggregate queries so you can identify whether a statement reads data, changes access, or removes an object.
  • Review backup purposes and transaction boundaries by tracing what happens to stored data before and after a commit.
