Hi,

I am now using Seal report to connect to Oracle DB. But the output contains Chinese character. All these show as ???. I assume it's related to coding. But how can I change the coding for Seal report?

Thanks,

John

Seal Report is an unicode application and should support chinese and arabic....

In made a small report to show that it works
test chinese arabic.srex (3kb) downloaded 2 time(s).

Are you sure of your Oracle driver ?

Thanks for your reply.

Please take a look at the screenshot attached. Top one is Seal report. Bottom one is PLSQL client output.

Yes but PL/SQL will not use the same driver as Seal Report...
Did you use the Oracle driver (ODAC): https://www.oracle.com/d...gies/odac-downloads.html ?
Perhaps it is specific for unicode characters.

I am using instantclient-basic-windows.x64-12.2.0.1.0 and instantclient-odbc-windows.x64-12.2.0.1.0-2. Created a System DSN. Then use OLEDB ODBC in Seal report. Is that OK?

Perhaps you should use the native OLEDB Oracle driver instead of OLEDB over ODBC, sorry we do not have experience with unicode with Oracle....
Is is a more general question: OLE DB Oracle unicode support, you can search the internet

Thanks buddy.

I have found the solution. So post the steps here. Hope someone else can benefit from my case.

1. When create DSN, check 'Froce SQL_WCHAR support' under 'Workrounds'
2. Run [select userenv('language') from dual] by using any Oracle client and note the output
3. Create a system variables 'NLS_LANG' and set the value as the SQL's output
4. Restart system and recreate data source in Seal Report
