Hi, I've being trying for the last couple of months to convert a MS Access to Mysql. I pull out data extract from around 100 + queries. These took about 5 months of solid work to develop and are extremely complex. I can convert these to mysql, but have one big problem. There is no last function in mysql. I know you can do a descending sort by ID and grab the first row to get the same thing. This will not work as I need to do it over several thousand different groups. So I need the last row per group.
I have been trying to write a aggregate last UDF function in mysql, and would consider this to be very simple, however, I can't get it to work. I don't really know how to program in C and my understanding of it is quite vague. I really need some help to do this from someone in the community. I have posted several times in the past and haven't heard anything from anyone. I am getting quite frustrated and are about ready to flag this exercise as a great waste of time. I have successful so far got the UDF to compile, and installed. I had to recompile mysql for HPUx to get it to support UDFs in the first place. It has taken me 50+ hours to export several hundred meg of data from access to mysql. I have even written quite a bit of code/scripts to get it to the point where I can start fixing things. So, please, can anyone help me with this. I don't expect someone to do this all for me, but just a LITTLE help would be nice. I will quite happily post this back into the community if I can get it to work. I have removed myself off the mailing digest as the volume is too high.
