When I'm Adding a new record with "cachedupdates" default field values is coming to null. But When I'm not using "cachedupdates" default values come correct. Sample Application Attached. Issue #2 When I use gotobookmark with cachedupdates table focus to another record. Forexample; Step by step, I’m getting bookmark after that I‘m doing begincachedupdates and I’m editing some fields, after this and I do cancelcachepupdates and gotobookmark but table focus to another record which is not same as getbookmark record.

As for the issues, please see my email reply, which is copied here for others to see: << When I'm Adding a new record with "cachedupdates" default field values is coming to null. But When I'm not using "cachedupdates" default values come correct. >> Default expressions for columns are not evaluated/populated when using cached updates. Default expressions can involve function/procedure calls and other types of complex evaluations that are not possible on the client with a remote session, since the client does not have direct access to the database catalog, the session state, etc. << This problem become when I make AlterTable with "ElevateDB Manager" >> You're specifying the IP address as a numeric constant, not a string constant. It should be specified as: DEFAULT '127.0.0.1' << When I use gotobookmark with cachedupdates table focus to another record. Step by step, I'm getting bookmark after that I'm doing begincachedupdates and I'm editing some fields, after this and I do cancelcachepupdates and gotobookmark but table focus to another record which is not same as getbookmark record. >> You can't use bookmark values from when cached updates are active to re-position to rows *after* the cached updates are no longer in effect. The rows have different internal row IDs, and that causes the GotoBookmark to move to the wrong row. ------------------- The cached updates use the replication functionality in ElevateDB, so they are functionally equivalent in terms of how they work. So, you can assume the same type of behaviors that you would if you were replicating updates from a machine on the other side of the planet. ------------ Tim Young Elevate Software www.elevatesoft.com |
