>>For years in powerbuilder we could connect to any dbms via odbc, we could use a builder (like the one we now have in vfp 8.0) to run a sql statement against a remote table, then we could change the data on the client and send the updates to the server. All these can be done now in VFP - even with some limitations like the 256 char limit. The differense is that with powerbuilder no matter if the backend is SQL server or oracle or anything, Powerbuilder can handle update conflicts. How can Powerbuilder do that in contrast with vfp 8.0, where to solve the update conflict problem we have to program differently for every specific backend (either changing the update statement or via stored procedures e.t.c.) Is this a vfp cursoradapter limitation or a backend or odbc limitation ?

Thank you for the response

my main question was how powerbuilder could manage the abstarction regarding the update conflicts (you dont bother for the backend) and for cursoradaptor we have to handle it differently depending on the back end. Or to put it differently, can the cursor adapter be programmed so that it can handle conflicts no matter which the back end is and of course without bothering making stored procedures??
