How to enable SQL Server-compatible configuration for database name Case sensitivity

Set the global variable lower_case_table_names to 1.

Lab:
1. lower_case_tables_name = 0 (default in Linux)
Start mysql directly and create tables MyTable and mytable in mytest
Mysql> use mytest;
Mysql> create table MyTable (id int not null, name varchar (10), dt date );
Mysql> create table mytable (id int not null, name varchar (10), dt date );
Mysql> show tables;
+ ------------------ +
| Tables_in_mytest |
+ ------------------ +
| MyTable |
| Mytable |
+ ------------------ +
By default, you can create both mytable and MyTable tables.

2. lower_case_tables_name = 1 (we need to set this case)
Go to the etc directory and edit the my. cnf file.
[Root @ MYSQLServer etc] # vi my. cnf
Find [mysqld]
Add a row at the end of its global variable: lower_case_table_names = 1
Save, exit, and restart mysql
[Root @ MYSQLServer etc] # service mysqld restart;
Go to mysql
[Root @ MYSQLServer mysql] # bin/mysql
Mysql> use mytest;
Mysql> select * from MyTable;
Mysql> select * from mytable;
The results of the two queries are the same. Both queries are mytable tables, but MyTable tables cannot be found (as you can see, but cannot be found)
Let's try again to create a MyTable table.
Mysql> create table MyTable (id int not null, name varchar (10), dt date );
ERROR 1050 (42S01): Table 'mytable' already exists
The table already exists.

Similarly, we can try to create the MyTest Library
Mysql> create database MyTest;
ERROR 1007 (HY000): Can't create database 'mytest'; database exists
You will also be prompted that the database already exists.

In this case, table names and database names are case insensitive.

Note: Before setting lower_case_tables_name to 1 in Unix, you must first convert the old database name and table name to lowercase before restarting mysqld. Otherwise, the old table cannot be found.
(In the above experiment, MyTable cannot be found when lower_case_tables_name = 1)
