ejc-sql auto-complete error

[stardiviner]

Here is my configuration:

(use-package ejc-sql
  :ensure t
  :commands (ejc-connect ejc-connect-existing-repl ejc-sql-mode)
  :config
  (defun my-ejc-sql-ac-setup ()
    (ejc-sql-mode 1)
    (auto-complete-mode 1)
    (ejc-ac-setup))
  (add-hook 'sql-mode-hook #'my-ejc-sql-ac-setup)

  ;; (advice-add 'ejc-connect :before
  ;;             #'(lambda (connection-name)
  ;;                 (switch-to-buffer-other-window (format "*ejc-sql %s*" connection-name))))
  
  (ejc-create-connection
   "PostgreSQL-db-postgres"
   :classpath "~/.m2/repository/postgresql/postgresql/9.3-1102.jdbc41/postgresql-9.3-1102.jdbc41.jar"
   :dbtype "postgresql"
   :host "localhost"
   :port "5432"
   :user "postgres"
   :password "324324"
   :dbname "postgres")

  (ejc-create-connection
   "MariaDB-db-test"
   :classpath "~/.m2/repository/org/mariadb/jdbc/mariadb-java-client/1.1.7/mariadb-java-client-1.1.7.jar"
   :dbtype "mysql"
   :host "localhost"
   :port "3306"
   :user "root"
   :password "324324"
   :dbname "test")
  
  (ejc-create-connection
   "MySQL-db-test"
   :classpath "~/.m2/repository/mysql/mysql-connector-java/5.1.32/mysql-connector-java-5.1.32.jar"
   :dbtype "mysql"
   :host "localhost"
   :port "3306"
   :user "root"
   :password "324324"
   :dbname "test")
  )

After ejc-connect, I input sel I got error in auto-complete:

Error running timer ‘ac-update-greedy’: (error "MySQLSyntaxErrorException Unknown column ’s.schema_owner’ in ’field list’  sun.reflect.NativeConstructorAccessorImpl.newInstance0 (NativeConstructorAccessorImpl.java:-2)

Is it because I use MySQL-db-test? My Arch Linux uses MariaDB to replace MySQL. I tried use :dbtype "mariadb". But it is not recognized. So I still use :dbtype "mysql" for My MariaDB server. So I got upper error exception.

@stardiviner Could you check it with the latest update, please?

[stardiviner]

I installed updated version package.
Then raised another error:

Error running timer ‘ac-update-greedy’: (error "ConnectException Connection refused (Connection refused)  java.net.PlainSocketImpl.socketConnect (PlainSocketImpl.java:-2)
")

[stardiviner]

I'm sure my mysqld.service is started and port is 3306.

[stardiviner]

I restarted MySQL daemon. It works correct now.
