Are mysql table names in linux case-insensitive?

MySQL table names in Linux are case-sensitive. However, for file systems where the file system is not case-sensitive, MySQL's behavior may be restricted by the file system and cause the table name to no longer be case-sensitive. , the reason is that MySQL uses the default file system on Linux, and the default file system is not case-sensitive for file names.

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

By default, MySQL table names in Linux are case-sensitive. This means that mytable, MyTable and MYTABLE are treated as different table names.

However, for file systems where the file system is not case-sensitive (such as most default Linux file systems), MySQL's behavior may be limited by the file system and cause table names to no longer be size-sensitive. Write.

The reason is that MySQL uses the default file system on Linux, and the default file system is not case-sensitive for file names. This means that if you create a table named mytable, then if you try to reference that table using MyTable or MYTABLE, MySQL will not be able to differentiate between them and will treat them as the same table name.

This behavior is often referred to as "table name case insensitivity". If you need to force MySQL to perform case-sensitive comparisons of table names on Linux, you can do so by modifying the settings in the MySQL configuration file (my.cnf). Specifically, you can set the lower_case_table_names configuration option to 0 (case sensitive) or 2 (case preserving).

It should be noted that before modifying this configuration option, please ensure that important database data has been backed up, because modification may cause problems with existing database and table names.

To sum up, by default, the MySQL table name in Linux is no longer case-sensitive when the file system is not case-sensitive. However, this behavior can be changed by modifying MySQL's configuration.
