You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

Ошибка выскакивает в adapter.Fill(table); (35 строка).
После попытки выбора второй строки ... или при попытке изменения выбранного пункта в первой строке ... В datagridview1 - см строки 54-68
Думал проблема связана с MySQL - переустановил - не помогло.
