Nexus DataAbstract Driver Memo Fields Issue -at least with 10.3.1 if not b4


(rposeikacbautomation) #1

I have a DA DB server connected to a Nexus DB server that has been
in use for years.
-A particular DA server app has not been updated for a while.
-I just added some new tables to the DA server app to reflect changes in the nexus DB server.
-THERE IS A SIDE-EFFECT… On tables with memo string fields (No changes made and were working previously) - the memo field can be read, but if a new record is made or a modification is made to the blob memo - the data is written as basically “???”.
–Reading existing data is ok, as soon as I POST (apply udpate to server) the corruption occurs.
Is there a change somewhere I need to consider?
-This may be an issue before 10.3.1. I cannot say.
The previous DA Server (compiled sept 2018 works just fine).

Seems to be an issue with 10.2 also with latest DA…

can you create a simple testcase that reproduces this issue, pls?
you can drop it directly to support@

(rposeikacbautomation) #4

ok -I have a very simple test project.
I have Nexus 4.5009

I will send you one (1) TestMemo.nx1 file and the project I used for
Delphi 10.3.1 with RemObjects Data Abstract for Delphi, Server Edition -

The delphi project was created with the DA wizard for
VCL server and client.

the nexus alias is called
and the file is located in c:\temp

The DAServer connects to localhost.

The DAClient has both the DA client AND a nexus direct connection.
The DA environment has the issue descrived. The Nexus environment ‘works’. If I write text via the DA connection - it posts ??. If I write text via the nexus connection - the text posts and is read after a refresh via the DA connection.

When you mean ‘drop’ at support@ you mean email?
thanks again
