### Q2. 2.1.x 版本 JDBC 连接 Power BI 时报错读取数据时报错，给定的关键字目前不在字典中。

先在数据库中执行 show collation，一般情况下会只有 utf8mb4_900_bin，charset 为 utf8mb4 这一行结果。该报错的主要原因是在连接 Power BI 时需要找33号 ID，即需要该表中有33 ID 的行，需要升级至2.1.5版本以上。

### Q4. JDBC 连接 2.1.x 版本报错从提供读取数据时出错："Character set 'utf8mb3' is not supported by .Net.Framework"。

该问题易在2.1.x 版本遇到，如果遇到该问题则需要把 JDBC Driver 升级到8.0.32。

### Q5. JDBC 的方式连接 2.1x 版本的 Doris 时使用 SQL Statment 语句时报错：“出了点问题，未将对象引用设置到对象的实例”。

需要在连接的库下执行一下如下语句创建一个表，创建成功后再次连接 Doris 即可正常工作

```
CREATE TABLE `bogus_table` (
`id` BIGINT NOT NULL,
`value` BIGINT NULL
) ENGINE=OLAP
DUPLICATE KEY(`id`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`id`) BUCKETS 10
PROPERTIES (
"replication_allocation" = "tag.location.default: 1"
);
```

This problem is easily encountered in version 2.1.x. If this problem occurs, you need to upgrade the JDBC Driver to 8.0.32.

### Q5. An error occurred when the SQL Statment statement was used to connect Doris of 2.1x using JDBC :"Something went wrong Object reference not set to an instance of an object".

You need to execute the following statement in the connected database. After the execution is successful, connect Doris again to work properly.

```
CREATE TABLE `bogus_table` (
`id` BIGINT NOT NULL,
`value` BIGINT NULL
) ENGINE=OLAP
DUPLICATE KEY(`id`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`id`) BUCKETS 10
PROPERTIES (
"replication_allocation" = "tag.location.default: 1"
);
