doa41d2010 and EOracleError.Message

[Janis]

We have following issue:

EOracleError message contains ORA exception with useful data hidden as ???, for example ORA-01400 exception:

ORA-01400: cannot insert NULL into (???)

But should be:
ORA-01400: cannot insert NULL into ("SCHEMA1"."TABLE1"."FIELD1")

Versions:
DOA 4.1.1 (doa41d2010)
Delphi 2010
Oracle Client 11.2.0 32-bit
Oracle Server: 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production (with NLS_CHARACTERSET = 'AL32UTF8')

Thanks for any help already!

Do you literally get 3 question marks?

 

[Janis]

Yes, as shown in my sample.

 

[Marco Kalter]

Maybe it's a unicode issue. What is the NLS_LANG setting on the client?

 

[Janis]

NLS_LANG = LATVIAN_LATVIA.BLT8MSWIN1257

Changing to LATVIAN_LATVIA.AL32UTF8 didn't help.

 

[Marco Kalter]

I guess it's not an NLS issue then. What happens if you insert a NULL into this column from within SQL*Plus on the same PC?

 

[Janis]

SQL*Plus shows correct error message.
