hi,

we have a table in phoenix 4.4 which has a modifyrevision as a column..

when a thread updates the row the modifyrevision has to be incremented..

only option i can see is to use the upsert select to get the latest revision 
but since it is not atomic how do we avoid the dirty reads?is there any other 
way this can be done?


Thanks,

Pradheep
