Knime 数据库编写器节点中的用户拒绝创建命令

Question

在新的 KNIME 工作流程中。我创建了一个新的数据库连接节点和一个从 CSV reader 节点接受数据的新数据库写入器节点。数据库连接节点执行成功。当我执行数据库写入器节点时，出现 CREATE 命令被拒绝错误。

Database connector节点配置如下：数据库 URL：jdbc:mysql://localhost:3306/hello_knime_database
用户名：test
密码：测试

mysql 配置：

$ mysql -u test -p
mysql> show databases;
+----------------------+
| Database             |
+----------------------+
| information_schema   |
| hello_knime_database |
+----------------------+
2 rows in set (0.00 sec)
mysql> show grants;
+--------------------------------------------------------------------------
-------------------+
| Grants for test@localhost                                                                    
|
+--------------------------------------------------------------------------
-------------------+
| GRANT USAGE ON *.* TO 'test'@'localhost'                                                    
|
| GRANT ALL PRIVILEGES ON `hello_knime_database`.* TO 'test'@'localhost'                      
|
| GRANT ALL PRIVILEGES ON `hello_knime_database`.`hello_knime_database` TO 
'test'@'localhost' |
+--------------------------------------------------------------------------
-------------------+
3 rows in set (0.01 sec)

数据库编写器配置：
端口 1 输入：数据 table 约 32000 行和 15 列。
端口 2 输入：数据库连接器
Table姓名：你好

KNIME 版本：3.3.2

当我执行数据库编写器节点时，我得到：

ERROR Database Writer      0:3        Execute failed: CREATE command denied to user 'test'@'localhost' for table 'hello'

有什么线索是造成这种情况的原因吗？

Answer 1

来自MySql

A grant table reload affects privileges for each existing client connection as follows: Table and column privilege changes take effect with the client's next request. Database privilege changes take effect the next time the client executes a USE db_name statement.
Note
Client applications may cache the database name; thus, this effect may not be visible to them without actually changing to a different  database or flushing the privileges.
Global privileges and passwords are unaffected for a connected client. These changes take effect only for subsequent connections.
