I found a bug when I delete two databases. After the second database is deleted, he does this and crashes:
SELECT `DEFAULT_COLLATION_NAME` FROM `information_schema`.`SCHEMATA` WHERE `SCHEMA_NAME`='';
SHOW TABLE STATUS FROM ``;
/* SQL Fehler (1102): Incorrect database name '' */
SHOW FUNCTION STATUS WHERE `Db`='';
SHOW PROCEDURE STATUS WHERE `Db`='';
SHOW TRIGGERS FROM ``;
/* SQL Fehler (1102): Incorrect database name '' */
SHOW EVENTS FROM ``;
/* SQL Fehler (1102): Incorrect database name '' */
Seems to me, as if he wants to show the last opened database, but it's not there any more.
Can you repoduce the error?
Have a nice day,
Chris
