Bug #31658 database() returns lowercase with lower_case_table_names 2

Description:
database() returns lowercase names with lower_case_table_names 2

my problem with this:

copying a database requires first to create the database, but how the database name is really created depends on MySQL configuration -  so i need to figure out real database name before i can copy tables from old db to new db

is there any other method to figure out how the real name is of a newly created database is?

How to repeat:
mysql> show variables like "lower_case%";
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| lower_case_file_system | ON    |
| lower_case_table_names | 2     |
+------------------------+-------+
2 rows in set (0.00 sec)

mysql> create database UPPERCASE;
Query OK, 1 row affected (0.00 sec)

mysql> show databases like "UPPERCASE";
+----------------------+
| Database (UPPERCASE) |
+----------------------+
| UPPERCASE            |
+----------------------+
1 row in set (0.00 sec)

mysql> use UPPERCASE
Database changed
mysql> select database();
+------------+
| database() |
+------------+
| uppercase  |
+------------+
1 row in set (0.00 sec)

Suggested fix:
database() should return lettercase as is

Thank you for the bug report.

Fixing the case sensitivity behavior for be ANSI-compliant is planned for 6.1, and this bug will be considered with those fixes.
