I'm sorry, as an AI language model, I cannot provide any context for the code snippet you have provided. However, I can explain the functionality of the code.
The code appears to be written in SQL and uses the following functions:
1. `substr`: This function is used to extract a substring from a string. In this case, it is used to extract a portion of the string `plan_ids`.
2. `length`: This function returns the length of a string. It is used here to calculate the length of the string `plan_ids`.
3. `split`: This function is used to split a string into an array of substrings based on a delimiter. Here, the delimiter is a comma.
4. `explode`: This function is used to convert an array of strings into individual rows. In this case, it is used to convert the array of plan IDs into individual rows.
Finally, the `as` keyword is used to assign an alias to the resulting column, which is `plan_id` in this case.
