LLBL gen than basically doesn't generate delete statements at all automatically, when does it generates delete statement while persisting?
may be the Impedence mismatch between database & Objects can't go away whatever methodology use<gr>. I am migrating from the Powerbuilder world & it does have two different methods: Delete (filtered to a delete buffer & delete statements are generated when persisted) & RowsMove(this one is same as Delete in LLBL & delete statement is not generated when persisted).
May be I am trying to understand how the bindings of collections happen with a bindingsource & hence with a datagridview(DGV).
If I get a filtered object list from a collection & bind it with DGV am I still referring to the instances in the collection or a new copy of the instances is made?
If I get another filtered object list from the same collection & bind it with another DGV does the first DGV content changes or what happens?
Basically I am trying to work around this problem of having to handle the delete in a different collection manually.
If Insert, update & select can transfer into DML codes automatically, why not the delete?
I know this logical delete is an exception behavior that could be same as update in cases where somebody when updating should cause it as an insert statement instead where physical update & delete is not permitted in certain databases.
