Re: DBI-LINK not support special support?

Hi all,
I use dbi-link to connect for oracle db 10g and 11g, and
big problem give to me:
example:
select * from table(oracle)
çavân
When dbi-link call information from oracle his show
?cv?an

In pure perl script no have problems too.

Any ideas for help me?

Regards,

 
Paulo

This is not a question for the hackers list.

Set the environment variable NLS_LANG for the postgres process
to the correct Oracle character set.

Environment has been applied
[postgres(at)gcomdesenv oracle]$ export

But reading official page on https://github.com/davidfetter/DBI-Link/blob/master/README.Oracle  I see this:
 

Environment variables:
----------------------

Oracle needs certain environment variables to function correctly:

ORACLE_HOME must be set to the directory where the software is installed
            (not required with Instant Client)
NLS_LANG must be of the form <territory>_<language>:<charset>, where
              <territory> influences settings like the decimal separator
                          (use AMERICAN if you want a period)
              <language> is the language for Oracle error messages
              <charset> must be the Oracle character set corresponding
                          to your PostgreSQL database encoding
            For example, if your PoatgreSQL database encoding is UTF8, use
            AMERICAN_AMERICA.AL32UTF8
TNS_ADMIN directory containing sqlnet.ora and tnsnames.ora (if you need
            these files)

Other environment variables influence how numbers, dates and timestamps
will be displayed and can be useful if you want to process the data with
PostgreSQL.

You can specify environment variables by passing them in YAML format
as fifth argument to make_accessor_functions(), for example:

---
- env_name: ORACLE_HOME
  env_value: /ORACLE/product/10.2.0
  env_action: overwrite
- env_name: NLS_LANG
  env_value: AMERICAN_AMERICA.AL32UTF8
  env_action: overwrite
- env_name: NLS_DATE_FORMAT
  env_value: "YYYY-MM-DD HH24:MI:SS"
  env_action: overwrite
- env_name: NLS_TIMESTAMP_FORMAT
  env_value: "YYYY-MM-DD HH24:MI:SS.FF"
  env_action: overwrite
- env_name: NLS_TIMESTAMP_TZ_FORMAT
  env_value: "YYYY-MM-DD HH24:MI:SS.FF TZH"
  env_action: overwrite
- env_name: TNS_ADMIN
  env_value: /ORACLE/product/10.2.0/network/admin
  env_action: overwrite
- env_name: LDAP_ADMIN
  env_value: /ORACLE/product/10.2.0/ldap/admin
  env_action: overwrite--------------------------------------------

 * dbh attributes:  {AutoCommit => 1, RaiseError => 1}
 * dbh environment: NULL
 * remote schema:   NULL
 * remote catalog:  NULL
 * local schema:    hr
 */

UPDATE
    pg_catalog.pg_settings
SET
    setting =
        CASE WHEN 'dbi_link' = ANY(string_to_array(setting, ','))
        THEN setting
        ELSE 'dbi_link,' || setting
        END
WHERE
    name = 'search_path'
;

SELECT make_accessor_functions(
    'dbi:Oracle:hr;host=localhost;sid=xe',
    'hr',
    'foobar',
    '---
AutoCommit: 1
RaiseError: 1
',
    NULL, --dbh environment:
    NULL,
    NULL,
    'hr'
);
-------------------------------------------------------------------

In function  make_accessor_functions()
, the manual tell to put  in dbh environment  env variables but I not sucess .
I try this:
SELECT make_accessor_functions(
    'dbi:Oracle:dbi:Oracle:hr;host=localhost;sid=xe',
    'hr',
    'foobar',
    '---
AutoCommit: 1
RaiseError: 1
',
'
    -env_name: NLS_LANG
    env_value: AMERICAN_AMERICA.AL32UTF8
    env_action: overwrite
',
    NULL,
    NULL,
    'hr'
);

ERROR:  error from Perl function "make_accessor_functions": error from Perl function "set_up_connection": error from Perl function "add_dbi_connection_environment": In dbi_link.add_dbi_connection_environment, settings is a >HASH<, not an array reference at line 8. at line 94. at line 35.

Any ideia for help

You are much more likely to get help if you ask on the right mailing
list, instead of here.

The environment has not been applied correctly, because you
see question marks, which is Oracle's replacement for characters
it cannot translate. I don't know what went wrong. The environment
variable must be set when the postmaster is started.

Your YAML is wrong.
