更新：来自InterBase论坛帖子：Unicode Databases in InterBase – Really?(它不是我的一个帖子,但它表明InterBase XE中仍然存在一些问题).
Here are some reports I’ve submitted:
QC#92867 – String fields are blank
coming from Views only if the View
includes a Union,and when using a
ClientDataSet. This was found as
missing data on a few of my reports,
which no longer work.07001 – IB Character column data
Character fields (eg: Char(1)) are
padded with blanks when retrieved
through a stored procedure. Tests fail
– eg: If Active = “Y”. I make heavy use of stored procedures with forms
and these do not work.07002 – IBsqlMonitor fails. The
output of IBsqlMonitor is somewhat
garbled making this tool useless. (So,
even my shovel is broken!)Unreported – Persistent fields in
TClientDataSet fail for TWideString.
