Are MySQL Table Names Case-Sensitive, and How Can I Control This?

Are Table Names in MySQL Case-Insensitive?

In MySQL, the case sensitivity of table names depends on the underlying operating system on which the database server runs.

Generally, in Windows, database and table names are not case-sensitive, while they are case-sensitive in Unix environments, including Ubuntu. This occurs because MySQL databases correspond to directories, and tables to files within those directories. Thus, the case sensitivity of the operating system impacts the case sensitivity of database objects.

However, MySQL's lower_case_table_names system variable allows for customization. By setting this variable in the my.cnf configuration file, you can control whether table names are stored in upper or lowercase on disk. The default value of 0 indicates case sensitivity, while a value of 1 or 2 specifies case insensitivity.

For more detailed information on identifier case sensitivity, refer to MySQL's documentation on Section 10.2.2: Identifier Case Sensitivity.
