### notice
We should turn on the switch for the ARRAY types feature with the following command before use:
```
$ mysql-client > admin set frontend config("enable_array_type"="true");
```
In this way the config will be reset after the FE process restarts. For permanent setting, you can add config `enable_array_type=true` inside fe.conf.
### example

```
mysql> INSERT INTO `array_test` VALUES (1, [1,2,3,4,5]);
mysql> INSERT INTO `array_test` VALUES (2, array(6,7,8)), (3, array()), (4, null);
mysql> INSERT INTO `array_test` VALUES (2, [6,7,8]), (3, []), (4, null);
```
Note: The above sql supports the array() function only in non-vectorized scenarios, but not in vectorized scenarios.

### notice
使用前可以通过如下命令打开Array开关:
```
$ mysql-client > admin set frontend config("enable_array_type"="true");
```
这种方式下Array开关会在Fe进程重启后重置，或者在fe.conf中添加`enable_array_type=true`配置项可永久生效。
