MySQL case sensitivity table name on MacOS with case insensitive file system

Question

I have researched a lot and what I understand to make database tables name sensitive, you have to set the variable lower_case_table_names=0. Im on osX. I did this change in

Answer 1

Tables and Columns are Case Sensitive in Linux! To make them case insensitive, follow this:

Open terminal and edit /etc/mysql/my.cnf

sudo nano /etc/mysql/my.cnf

Underneath the [mysqld] section, add:

lower_case_table_names = 1

Restart mysql

sudo /etc/init.d/mysql restart

Then check it here:

mysqladmin -u root -p variables

Just altering the lower_case_table_names setting isn't enough. It needs to be done before you import your database(s).

The MySQL 5.7 documentation lists a procedure for moving between Windows and Linux/UNIX. A note about Mac OSX from that reference:

One notable exception is OS X, which is Unix-based but uses a default file system type (HFS+) that is not case sensitive. However, OS X also supports UFS volumes, which are case sensitive just as on any Unix.

Review the manual page to ensure that your desired rules for enforcing case sensitivity are followed. Take a look and verify that you did these steps in the correct order:

To convert one or more entire databases, dump them before setting lower_case_table_names, then drop the databases, and reload them after setting lower_case_table_names:

1 - Use mysqldump to dump each database:

mysqldump --databases db1 > db1.sql

mysqldump --databases db2 > db2.sql

... Do this for each database that must be recreated.

2 - Use DROP DATABASE to drop each database.

3 - Stop the server, set lower_case_table_names in the [mysqld] section of your \etc\mysql\my.cnf file, and restart the server.

4 - Reload the dump file for each database. Because lower_case_table_names is set, each database and table name will be converted to lowercase as it is recreated:

mysql < db1.sql

mysql < db2.sql

Concerning the MySQL System Variable lower_case_table_names Server Variable (or setting):
