Hi Panos, thank you for your hints. I'll take a look for the file. I haven't found that file before. Well UDFs may help, but I want to implement some additional compression schemas for some performance research. So do you think UDFs are still a good idea to measure the performance between compressed and uncompressed data?

Hi there,
I am looking for the function where I can manipulate the values from an insert or update statement.
For now, I am using a Solaris 10 system. But I havent found the functions where the insert or update will get done. I have looked trogh the files stream.c, mapi.c and mclient.c. But everytime I tried to change the values in the variables nothing happend.
Can somebody please help me?
Thanks in advise
Thomas
