I've been thinking about simply surfacing the necessary stuff right into
TIBODataset. If you would like to go that route I'll get the changes into
the next sub-release.

Subject: [IBO] DML Caching with TDataset compatible IBO components


Hi all,

I'm in process of writing a small wrapper component that
allows to adjust the DML Caching stuff of a TIBOQuery by
using InternalDataset.

Some problems arised during testing, namely DML Caching
for a TIBOQuery doesn't work for edit and delete
operations. I've nailed the edit problem down to the
method TIB_Statement.ProcessLinkEvent (...), line 24155
in IB_Components.pas

When using DML Caching with TIBOQuery, then StatementLinkCount
is always 0, whereas with a native TIB_Query it is 1, and
so it will proceed down to ProcessEvent(...). Dunno right
now about the problem with delete operations.

Well, that issue isn't really pressing for me, I only
thought some people might be interesting in that wrapper
component, because they have asked how to use DML
Caching with non-native IBO access components.

Has anybody tried to use DML Caching with IBO TDataset
components by using InternalDataset?

I'm using Delphi 6 Prof. and IBO 4.3Aa.


Thanks,
Thomas Steinmaurer
