| OUTER | |
| If OUTER specified, returns null if an input array/map is empty or null. | |
| posexplode() is similar to explode but instead of just returning the elements of the array | |
| it returns the element as well as its position in the original array. | |

| device_id rank | |
| 12 1 | |
| 12 2 | |
| 12 3 | |
| 10 1 | |
| 10 2 | |
| ``` | |
| Then use the sql below | |
| ``` |
| ShadowsocksX-NG现在已经支持一键开启http代理了，只需要在mac的terminal里设置一下就好。 | |
| export http_proxy='127.0.0.1:1087' | |
| export https_proxy='127.0.0.1:1087' |
The assert keyword is used when debugging code.
The assert keyword lets you test if a condition in your code returns True, if not, the program will raise an AssertionError.
You can write a message to be written if the code returns False, check the example below.
assert word.endswith(suffix), "Given word doesn't end with given suffix"
