- Can mysql database store images?
- Storing images in a MySQL database is feasible, but not best practice. MySQL uses the BLOB type when storing images, but it can cause database volume swell, query speed and complex backups. A better solution is to store images on a file system and store only image paths in the database to optimize query performance and database volume.

- Whether mysql automatically indexes foreign keys
- MySQL's foreign key constraints do not automatically create indexes because it is mainly responsible for data integrity, while indexes are used to optimize query speed. Creating indexes is the developer's responsibility to improve the efficiency of specific queries. For foreign key-related queries, indexes, such as composite indexes, should be created manually to further optimize performance.

- Are mysql and sql the same
- MySQL and SQL are brothers, not twins. SQL is a database query language standard, while MySQL is a relational database management system (RDBMS) that follows the SQL standard. There is the following difference between the two: SQL defines rules for interacting with the database, and MySQL is a concrete implementation of these rules. Standard SQL statements can run on any database system that complies with SQL standards, but may require fine tuning. Functions and syntaxes specific to a specific database system are only applicable to that system, such as the LOAD_FILE() function of MySQL. Learning SQL is essential for operating any database system, while learning MySQL and other specifics
