SQLgrey encountered an SQL error ...

[nicola.piazzi]

USE sqlgrey;
SHOW VARIABLES LIKE '%collation%';
+----------------------+--------------------+
| Variable_name | Value |
+----------------------+--------------------+
| collation_connection | utf8_general_ci |
| collation_database | latin1_swedish_ci |
| collation_server | utf8mb4_unicode_ci |
+----------------------+--------------------+

As you can see sqlgrey create its own database in latin1 but now with mariadb EFA uses utf8 connection, this give the error : Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8mb4_general_ci,COERCIBLE)

Other DB in EFA are altrady utf8

We need to change database, but also tables and columns to be compatible with connection
Here sequence , worked for me
You can do it without problem


mysql -u root -pXXXXXXXXXXXXXX
USE sqlgrey;

ALTER DATABASE sqlgrey CHARACTER SET 'utf8mb4' COLLATE 'utf8mb4_unicode_ci';

ALTER TABLE config CHARACTER SET 'utf8mb4' COLLATE 'utf8mb4_unicode_ci';
