Issue with CR and LF in json. "\r" destroys table in template

mdehaanJan 31 2025

I have created a simple template in Word (sample.docx) and some json-files sample1.txt, sample2.txt and sample3.txt holding the data (I have uploaded the files as txt-files, as json is not allowed)
The data is coming from an Oracle table and printed to the file using UTL_FILE-package with a script like sample.sql
The text contains new-line charcaters to assure lines to be printed on a new-line.

In Oracle this new-line is translated as chr(13)||chr(10).
When converted to json, which is required when using the pre-built-function, this is translated as \r\n. (see various attempts with json-files sample1.txt, sample2.txt and sample3.txt, resulting in sample1.pdf, sample2.pdf and sample3.pdf)

The generated pdf's show that \r is ruining the table structure, while only using \n does not result in a new-line.

Is there someone out there that can help me solving this issue?
I really like the OCI-function solution, but when I won't be able to control the new-lines, then this will be quite useless for me.

Hi Salomon,

please have a look at this blog post written by @ulrike-schwinn-oracle :

I hope this answers your question, if not, please shout!

@martinbach-oracle - No, it doesn't answer my question. Article you pointed to shows uses:

SQL> alter system set sql_history_enabled=true scope=both;

And in my post I said “Works fine when enabled on system level”. My question was about

SQL> ALTER SESSION SET SQL_HISTORY_ENABLED = TRUE;

where I showed SQL history was NOT captured even though it should be based on SQL_HISTORY_ENABLED:

Modifiable **ALTER SESSION**, ALTER SYSTEM

As per the article I shared the situation is as follows at the moment

  • You must enable SQL history PDB-wide (only a DBA can do that) so there's a certain level of control over the feature
  • Your session has access to the SQL history
  • If you don't want to record anything, set sql_history_enabled to false.

I'm currently assessing if that's intended behaviour (in which case the documentation should be amended) or a feature not working as it should (in which case it needs fixing). The parameter is indeed session-modifyable, but not in the sense you expected.

We'll keep you posted.

Do you mean it must be enabled on system level and not on session level and all session can do is disabe it for the session?

Yes,

that's correct as of Oracle Database Free 23.6.

Thanks Martin, I hope this will be added to 23AI docs soon.
