Date Reported: 05/13/97
Severity: Critical
Type: Basic Functionality Failure
Problem:
Field sizes on pseudo-blobs and blobs now return a
different iLen than with earlier version of the BDE.
This in its self is not a problem but Delphi, in some
cases, holds field and blob sizes in the EXE causing
an exception "field < field_name > is not of
expected type". In effect, every Delphi2
application that used the BDE3.x to create the field
information, now cannot run with BDE4.0

Using a master / detail relationship with cached

Calling DbiStartSession then DbiCloseSession in a

BDE loaded in memory.
