Hi,

Firstly, I'm a relative newbie to PL/SQL Developer, but love it so far. We have recently changed over from SQL Developer to PL/SQL Developer.

We're running 11gr2, and I believe my NLS_PARAMETERS are set up correctly, but I'm experiencing the below problem.

In SQL Developer (and Toad actually) the below displays and works correctly:

PKG_DELIMITED.WORD(p_column_list(i), 2, '$','''');

However, in PL/SQL Developer it displays as below, and invalidates the call as the '$' is not recognised and is parsed as a '?':

PKG_DELIMITED.WORD(p_column_list(i), 2, '?','''');


Please note...I've had to replace the special character causing the problem (I believe it to be chr(172)) with a '$' on the 5th line of text above, as it wont let me post the exact character as it breaks the post...the character can be seen by holding shift key and pressing key directly below escape key...

Could you advise how to resolve this, or has anybody else experienced this?

Many Thanks for any help/guidance in advance!

Dave

You can check if you have "Unicode enabled" option checked in PL/SQL Developer settings (Tools / Preferences / Oracle / Options). The problem may be related to the fact that PL/SQL Developer is unfortunately not a fully Unicode enabled Windows application. You can also check your Windows setting for non-unicode applications (somewhere in regional/lingual settings of Windows).
If nothing helps, post info on your Windows version and it's regional settings and the NLS values as reported by PL/SQL Developer (in Help / Support Info / Info) and by Oracle itself ("SELECT * FROM nls_database_parameters").
PS.: The character you are referring to is probably either tilde (~) or grave accent (`) - they should not pose a problem in most Latin-based alphabets/charsets/encodings.

Hi, thank you for the response.

Unfortunately, I have already tried changing the "Unicode Enabled" setting, and the same problem occurs whether this is enabled or disabled.

It wasn't actually the tilde or the grave accent that was causing the issue, it was the "not" symbol, as used in mathematical equations.

Can be found here under "Math Symbols"..

Thanks

You mentioned before, that the problematic character is located on a key just below "Esc" key on your keyboard. Classic EN-US/PL keyboards usually have tilde/accent key there. You did not mention what keyboard layout you have, and I did not notice your location data (UK), so my mistake - sorry. You did state that the character is probably "chr(172)", which indicates something different than tilde/accent, but you weren't sure and 172 character code is code-page/encoding dependant. Again, sorry for assuming incorrectly.

As I said:

Settings you gave look good. (I'd try to check if changing NLS_LANG to something that does not contain space, but still uses same code page, like "ENGLISH_AMERICA.WE8MSWIN1252" but as far, as I know, "ENGLISH_UNITED KINGDOM.WE8MSWIN1252" is correct.)

What you did not give is an important Windows setting: "Language for non-Unicode programs". It should be on "Administrative" tab of "Region and Language" configuration window (where you can also choose various formats and location on other tabs). It should probably be "English (United Kingdom)". If it's not, then that's the most probable cause of the problem. If it is, then I'm afraid I have no idea what else you could try or check. Allround Automations should kick in and help you diagnose the problem.

Thanks for the response again Hilarion...

The "Language for non-unicode programs" is already set to English (United Kingdom).

Thanks for your help and taking them time to have a look...hopefully someone from Allround Automations can help.

Many Thanks,
Dave

I believe you are talking abount Negation character
http://en.wikipedia.org/wiki/Negation

Try to use chr(172) or unistr('\00AC').

If you have ANSI NLS settings (an you do) PLD heavily rely on Windows setting that Hilarion pointed, but doesnt handle it good enough.

Not sure why, but IvanZ's message reminded me that there might be a workaround for your problem, DaveE. What you could try is: turn back on the Unicode support in the PL/SQL Developer and launch it with altrered NLS_LANG environment variable, with encoding/charset set to some Unicode one, like "ENGLISH_UNITED KINGDOM.AL16UTF16". You can specify it as command line parameter for PL/SQL Developer executable file, or in "params.ini" file.
I use that "trick" to be able to see (view/edit) data (and/or code) in databases that use charsets with Cyrillic alphabet (in your case it might be a bit better to use UTF-8 encoding insead of UTF-16 that I'm using).

As I wrote, your settings should work fine as they are (and - as you stated - they do in other applications) and Allround Automations should try to fix the application error, which prevents it, but the trick described above may let you work relatively well while waiting for proper solution.

This trick helps when you READ from the database, but you may have *load of problems trying to WRITE to it (in case of UTF -> ANSI conversion handled by PLD).
