#定义自己的命令 | ||
|
||
大家可以使用系统内置的一些命令,具体查看方式如下: | ||
|
||
```sql | ||
!show help; | ||
``` | ||
|
||
此外还内置了如下两个指令: | ||
|
||
```sql | ||
!desc jdbc; | ||
!kill 任务id; | ||
``` | ||
|
||
|
||
用户也可以定制自己的指令,比如用户自己实现kill指令: | ||
|
||
```sql | ||
set kill = ''' | ||
-- 注意结尾没有分号 | ||
run command Kill.`{}` | ||
'''; | ||
``` | ||
|
||
接着就可以使用`!`来使用kill指令了。 | ||
|
||
```sql | ||
!kill jobId; | ||
``` |
