how to verify the encoding of a blob file

AlibuneJun 15 2018 — edited Jun 15 2018

Hi everyone!

I have a browse item on my application that get the xml file and put it into a xmltype column on my table and i'm using this process:

declare  
  l_xml      xmltype;  
  l_xml_blob apex_application_temp_files.blob_content%type; -- blob;  
  l_filename apex_application_temp_files.filename%type;  
begin  
  
  select f.blob_content,f.filename  
    into l_xml_blob,l_filename  
    from apex_application_temp_files f  
    where f.name = :P201_XMLFILE;  
  
  --create xmltype from blob  
  l_xml := xmltype(l_xml_blob, nls_charset_id('UTF8'));--specify file encoding  
  
  --and now just insert the record  
  insert into xml_tab(id,filename,xml) values (xml_tab_seq.NEXTVAL,l_filename,l_xml);   
  
end; 

but sometimes i'll get files with encoding that is not UTF-8, how can i veriffy the file encoding to define which type of code i will use?

I'm using Oracle APEX 5.1 and Oracle Database 11G XE.

Hi,
There are few issues in the upgrade that might arise concerning logins:
with default install oracle 19 password are case sensitive
The password 'format' changed. You can check in dba_users
You might need to add to sqlnet.ora the parameter SQLNET.ALLOWED_LOGON_VERSION_SERVER=11
look into https://docs.oracle.com/en/database/oracle/oracle-database/18/spmsu/finding-and-resetting-user-passwords-10g-password-version.html#GUID-D7B09DFE-F55D-449A-8F8A-174D89936304
It will cover some of it.
Regards,
Hadar

Thanks Hadar. The password issue I knew about. I added the code to SQLNET.ORA in both the oracle_home/network/admin folder and the instantclient/network/admin folder and now get an ORA-12504 error.
I added both a tnsnames.ora and listener.ora files to both folders (with appropriate settings) but can't get past the 12504 error.
Any ideas? Greatly appreciated!
tnsnames.ora (orcltest is name of database, brian-surface4 is name of PC)
LISTENER_ORCLTEST =
(ADDRESS = (PROTOCOL = TCP)(HOST = Brian-Surface4)(PORT = 1521))

ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

ORCLTEST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Brian-Surface4)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcltest)
)
)
listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oracle\WINDOWS.X64_193000_db_home)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\oracle\WINDOWS.X64_193000_db_home\bin\oraclr19.dll")
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Brian-Surface4)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

Just to clarify, do you mean you upgraded the database the app is still at Legacy 11g app client? You are testing this where the database and client are on the same host?
