ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

ALTER TABLE table_name CONVERT to CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

ALTER TABLE table_name Change column_name column_name VARCHAR (191) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

| variable_name | Value |

+---------------+--------------------------------------------+

| Sql_mode | strict_trans_tables,no_engine_substitution |

+---------------+--------------------------------------------+

1 row in Set (0.00 sec)
