MariaDB vs MySQL differences and migration considerations in MariaDB - Examples & AI Generator

Switching between MariaDB and MySQL can be complex, with key differences impacting syntax, storage engines, and performance tuning. Developers migrating or maintaining systems need to understand subtle changes, such as function behavior, SQL modes, and default configurations. Mastering these manually slows productivity and risks errors, especially during migrations.

AI2sql eliminates the need to memorize MariaDB vs MySQL differences and instantly generates syntax-ready queries for MariaDB, so you can focus on results—not troubleshooting SQL.

MariaDB vs MySQL differences and migration considerations Syntax in MariaDB

Key Syntax Differences

• Storage Engines: MariaDB uses Aria as default, while MySQL uses InnoDB.

• JSON Support: MariaDB stores JSON as text; MySQL uses a native JSON type.

• Sequence and System Versioning: MariaDB supports SEQUENCE and SYSTEM VERSIONING natively.

• Functions: Functions like IFNULL() and CONCAT() behave similarly, but others (such as window functions) are more advanced or differ in MariaDB.

MariaDB vs MySQL differences and migration considerations Examples You Can Generate Instantly

Example 1: Migrating a JSON Column from MySQL to MariaDB

-- In MariaDB, store JSON as TEXT
ALTER TABLE customers 
  CHANGE details details TEXT;

Business context: Prepare customer records for migration where MySQL used a native JSON type.

Example 2: Replacing AUTO_INCREMENT with SEQUENCE

-- MariaDB native SEQUENCE
CREATE SEQUENCE order_seq START WITH 1;
ALTER TABLE orders 
  MODIFY order_id INT DEFAULT NEXTVAL(order_seq);

Business context: Ensure order IDs are managed using MariaDB's advanced sequence support.

Example 3: Migrating System Versioned Tables

-- Enable system-versioning in MariaDB
ALTER TABLE products 
  ADD COLUMN row_start TIMESTAMP(6) GENERATED ALWAYS AS ROW START,
  ADD COLUMN row_end TIMESTAMP(6) GENERATED ALWAYS AS ROW END,
  ADD PERIOD FOR SYSTEM_TIME (row_start, row_end),
  WITH SYSTEM VERSIONING;

Business context: Track product price changes over time, using MariaDB's native system versioning.
