 Description   

I run the following SQL script with a Linux server with --lower-case-table-names=0:

CREATE DATABASE db1;
 
CREATE TABLE db1.t1 (a INT);
 
SELECT * FROM db1.t1;
 
SHOW OPEN TABLES IN DB1;


+----------+-------+--------+-------------+
 
| Database | Table | In_use | Name_locked |
 
+----------+-------+--------+-------------+
 
| db1      | t1    |      0 |           0 |
 
+----------+-------+--------+-------------+

Looks wrong. The expected result is empty set, as the database does not match.
