	I have been working with RTIs ingres for some time now, but have
only just noticed what I consider a serious flaw in the functionality that
it provides.  From all I know about it, it is impossible to have their
RDBMS provide your program with a row of your data, allow you program to 
transform it and the replace the transformed data in the same table in place
of the original data.  Their RDBMS provides a "REPLACE" capability, but only
replaces that can be computed in the "BACKEND" are allowed.  The other 
alternatives are to load the rows to be worked on into arrays, temporary
files, or "form" structures.  If I am missing something simple, please send
me mail, but if this is actually so please comment in news if this is the 
general situation for other products, or if this is for some reason 
desirable.
