Are there limitations or best practices for using multiple foreign keys in a single table in MySQL?

When using multiple foreign keys in a single table in MySQL, it is important to consider the relationships between the tables and ensure that the foreign keys are properly defined to maintain data integrity. It is recommended to use meaningful column names for the foreign keys and to properly index them for performance. Additionally, it is best practice to use ON DELETE and ON UPDATE constraints to handle cascading actions when related records are deleted or updated. 

CREATE TABLE table_name (
    id INT PRIMARY KEY,
    foreign_key1 INT,
    foreign_key2 INT,
    FOREIGN KEY (foreign_key1) REFERENCES other_table1(id) ON DELETE CASCADE ON UPDATE CASCADE,
    FOREIGN KEY (foreign_key2) REFERENCES other_table2(id) ON DELETE CASCADE ON UPDATE CASCADE
);
