Some comments:
- If you try to write MySQL-Functions, I suggest starting from a very minimal function and extend bit by bit and checking if the results are as expected at every step. So you can catch up for single syntax/programming errors which is easier than to be faced with all of them at once
- The mysql function syntax seems to me a bit limited in comparison with every real programming language, so I myself would never write anything but really needed snippets(if at all) as mysql functions.
- In did not review your code in whole. But as you saw from my small 20 Line MySQL-Function: It already used 6 Seconds to complete, saying which huge amount of computing resources it needed. E. g. it was a very inefficient way to get it done. When I look at your code, you perform a lot of queries which should be all be very fast though. But I just wanted to note that some queries with big data sets can very quickly create huge loads of computing resources needed to get it done.
- In Backup MySQL-Functions are not saved by default with the mysqldump command. You need to keep that in mind and
- change your backup procedure, to have them included -or-
- tell your system administrator to have that done in case you are not responsible for backup -or-
- save your functions as textfiles outside the mysql database to be sure to have them backupped up
...and since my previous snippets where a whole lot more than you wanted, this search can be done very quick here.
UPDATE
Mmh. I detected that my solutions were not exactly what you wanted. But it should help nevertheless.
