Why Does MySQL Error 1064 Occur Despite Correct SQL Syntax for Foreign Key Constraints?

MySQL Error 1064: Syntax Blunder Despite Correct Syntax

Encountering MySQL Error 1064 indicates an issue with your SQL syntax. However, if the provided syntax appears to be correct, it's crucial to delve deeper into potential causes.

In this instance, the error occurred while adding a foreign key constraint. Initially, the syntax included the keyword "VISIBLE" after creating an index. Removing this keyword resolved the issue.

The question arises, why was the "VISIBLE" keyword used in the first place? In MySQL, indexes are visible by default, making the "VISIBLE" keyword redundant and potentially confusing.

Furthermore, MySQL Workbench may have included the "VISIBLE" keyword due to differences in syntax between MySQL and its derivative, MariaDB. MariaDB, used in XAMPP, handles indexes differently, as highlighted in the reference.

To avoid such issues, carefully review the differences in syntax between MySQL and MariaDB when working with XAMPP. Refer to official documentation or community resources for specific guidelines.
