What should I do to correct the above situation? NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM This situation? I don't want to change the patindex function call,īecause that would mean changes to a number of stored procedures in the database. I am no expert at Oracle Databases and I was wondering what should I do to correct Is it possible to alter the character set of a database. I was wondering, how do I re-set this situation. PATINDEX('A',CONVERT(LOGINID,'US7ASCII')) Select patindex('a',convert(loginid,'US7ASCII')) from logintable However when I change the function to use a convert like this ORA-06553: PLS-561: character set mismatch on value for parameter 'S2'
Select patindex('a',loginid) from logintable I was earlier able to run a function, but now it gives me an error stating That is NOT the clients NLS_LANG in there, thats the databases.

Hence - they are NOT getting the default NLS_LANG from the database - they are using the "default default" NLS_LANG (as described in that link i sent you before)Īll you've shown is that - yes, the databases character set is tkyte]$ export tkyte]$ echo tkyte]$ plus

Here is what I believe to be true:Ī) your INIT.ORA on the server has DD-MON-YYYY as the nls_date_format this is what you need to checkī) your UNIX clients have the same character set as the database - hence they take the database default which was over-ridden by your init.oraĬ) your WINDOWS clients do NOT have the same character set - they are setting the NLS_LANG in the registry to something other then US7ASCII. THis seems to me as if we use default settings, we would get this different behaviour. NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZH:TZMĪlso, I have checked this in another organisation from my friend. NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZH:TZM NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM How is it possible to store 8bit characters in 7 bit?īelow is ourput from v$NLS_PARAMETERS from both env. SVRMGR> select dump (TYPBZ) from equi where equnr like '%400059' SVRMGR> select typbz from equi where equnr like '%400059'

I read characters with an ASCII-Code > 127 were convert to ? So we test it with the SVRMGR. I wonder why the client (works on the AIX server) can present characters with an ASCII-Code > 127. I know it can present ASCII-Code from 0 to 127. We have a database with the character set US7ASCII. See the NLS guide, chapter 3 for details:Īctually, you may want to read through the entire document as it answers your questions directly in greater detail then I can here: You can convert the US7ASCII into WE8ISO8859P1 with later releases of Oracle (not 7.3, do not believe the functionality was implemented then). I've taken to creating all of my databases with 8bit now as I must support many countries and they get upset when we lose their special characters.Ĥ) cannot answer that for you. the 8bit can hold more types of characters so unless you are doing a US only application, 8bit might be more appropriate. The strings will be converted from one to the other and you may "lose" some characters.ģ) neither is more popular or flexible. You must consider this when using multiple charactersets. Going the other way, from 7bit to 8bit won't encounter any issues since the 7bit US7ASCII is a subset of the 8bit WE8ISO8859P1. My 7bit databasebase cannot store any 8bit characters, they will be mapped into the 7bit characterset (eg: the data will be DIFFERENT, I'll lose some characters that have the high bit set, they'll become some other character based on the rules for converting 8bit to 7bit).
If I export from an 8bit database and import into a 7bit - I'll undergo a characterset conversion. It can store 2 times as many characters as the 7bit one can (special characters with umlats and such).Ģ) there are no "problems" just considerations. The WE8ISO8859P1 is the standard western european 8 bit character set. US7ASCII for example is a 7bit character set, the high bit is "stripped".

1) will NLS is national language support and encompasses lots of things like how to display currency, whether we use a comma or a dot to separate numbers, how the name of a day is spelled and so on.Ĭharacter sets are how we store data.
