someone working to add merge?

Hi,


there is someone working in add the MERGE statement?

i don't find much about what a good implementation of merge must have...

i think what it needs to do is something like:

- try to lock the rows for update   - if the lock cannot be immediatly acquire ask why   - if the rows are already
locked,wait and try again?   - if no rows were found try de insert part   - if there was any other error, abort   -
elseupdate 

so i suppose we can reuse many of the code breaking the merge in 3
pieces... for now they are just thougths, i will think more in this
and try to implement it...

comments? ideas? suggestions?
