How To Review Implication Of Database Character Set Change On PL/SQL Code
Sep 14, 2013
We are converting WE8ISO8859P1 oracle db character set to AL32UTF8. Before conversion, i want to check implication on PL/SQL code for byte based SQL functions.
What all points to consider while checking implications on PL / SQL code? I could find 3 methods on Google surfing, SUBSTRB, LENGTHB, INSTRB. What do I check if these methods are used in PL/SQL code?
What all other methods should I check? What do I check in PL/SQL if varchar and char type declarations exist in code? How do i check implication of database character set change to AL32UTF8 for byte bases SQL function.

Creating thread so we can share experience on using the "Code review options" that comes along with "Toad formatter".
Personally I have used it only for formatting code but not to enforce SQL Standards. any inputs on this and if it's advisable to use this as corporate standard.

Currently my oracle database character set is we8mswin1252 and it is only containing English data as well as spatial data (which is in English of course). I would like to change the Database character set so it could accept Arabic characters.
I have checked the below command on a test DB and it worked fine, but I want to know if it's recommended as a best practice when changing the character set to accept arabic and this won't corrupt my old entered Data ?
SHUTDOWN IMMEDIATE
STARTUP RESTRICT
ALTER DATABASE CHARACTER SET INTERNAL_USE AR8MSWIN1256
SHUTDOWN IMMEDIATE
STARTUP

I want to change space allocation for character columns in my database, So it will store them as 'CHAR' and not 'BYTE'.my character set is
SQL> SELECT VALUE FROM V$NLS_PARAMETERS WHERE PARAMETER='NLS_CHARACTERSET';
VALUE
----------------------------------------------------------------
AL32UTF8
SQL> alter system set NLS_LENGTH_SEMANTICS='CHAR' scope=both;
System altered.I bounced the instance just to make sure
System altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
Connected to an idle instance.
SQL>
SQL>
SQL> startup
ORACLE instance started.
[code].....
And then I want to see that when I create a table with some varchar2 column,The space for it will be allocated by chars, and not by bytes! However, when I run a check of create table, this is what I get:
SQL> drop table check_char;
Table dropped.
SQL> create table check_char (some_name varchar2(10));
Table created.
SQL> select a.char_used
2 from all_tab_columns a
3 where table_name='CHECK_CHAR'
4 and a.owner='SYS';
C
-
B
SQL>
What is the reason for space allocation to remain in BYTES and not CHAR, or what else I can check?

I have to compare my SVN source code (packages, views etc) with the production code in the database like views etc (actually we are not sure that what we have in the svn is the final version of production code, we have objects created in the production database, but we don't have latest scripts for that. we have to deploy the svn code in the UNIX box).
So here the comparison is between the OS files and the database objects.
I thought I would get scripts of all the packages, views etc from the production database by using DBMS_METADATA or some utility and save the code in OS files then compare one svn file with OS file manually by using some comparison tools e.g toad provide one comparison tool.

I have the following chunk of code, which could return no rows, one row or many rows. When it returns one or many rows the DBMS_OUTPUT.PUT_LINE prints out my values. When no data is found 'Hello' is not printed?
Suggest a way I can change the code to make the exception print when no data is found?
SET SERVEROUTPUT ON;
BEGIN
FOR prec IN ( select * from xxx.part_maint where drop_partition = 'Y' )
LOOP
DBMS_OUTPUT.PUT_LINE (prec.SCHEMA_NAME || ' ' || prec.OBJECT_NAME);
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE ('hello');
END;

how do we know database character set is either single character set or multi character set?
While changing character-set from AL32UTF8 to WE8MSWIN1252 got "ORA-12712: new character set must be a superset of old character set".
Below are steps taken to resolve the issue -
ALTER DATABASE CHARACTER SET WE8MSWIN1252;
i got this error: ORA-12712: new character set must be a superset of old character set
below are the commands executed by me:
SQL> SHUTDOWN IMMEDIATE;
SQL> CONNECT SYS/password AS SYSDBA;
SQL> STARTUP MOUNT;
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER DATABASE OPEN;
SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE WE8MSWIN1252;
SQL> SHUTDOWN;
SQL> STARTUP;
SQL> QUIT;
And its working...
I have not done it in proper order. Neither have done ccsscan. Still, no user reported any issues. Do my changes truncated the data?

I have no knowledge about Barcode. The problem is an issue of Loyalty Cards of a Hotel and Restaurant to various customers and then these cards will be presented by the customers time to time in the Hotel as well as Restaurant. The Owner of the Hotel and Restaurant wants to generate separate barcode for each card and when this card will be presented then the bar code reader will readout the code and the system will calculate the amount of discount/rebate. Because if the data entry operator enter the code of the card through key board the it will be a chance of leakage or misuse of that card.

We have production DB 10g with character set US7ASCII. This DB stores Arabic data and English data.Production DB located in HP unix Operating System.
When I query data from DB through SQL developer data is shown as Junk or Unknown characters(Square Boxes).
Client (Workstation from where query is issued from SQL develope- Windows XP OS) Settings: NLS_LANG = AMERICAN_AMERICA.US7ASCII
In Client workstation Oracle 10g client is installed from where I used to query data through SQL developer. The problem is I am unable to see Arabic characters in the sense that it is displayed as Junk character. However English characters and Eneglish numeric values are displayed properly.
I tried below way to make sure that data is not corrupted: Converted "Name" column to hex value (rawtohex) and displayed its HEX value. Executed below query in UTF-8 DB.
select UTL_I18N.RAW_TO_CHAR(hex_value_of-name) from dual;
This displayed Arabic name properly in UTF8 DB.
Character set for this production DB can not be changed at this time. There are many applications which is based on this DB. All these applications are well capable of converting Junk data to Arabic to display in application.
My concern is: What I should required to do to view Arabic data properly through SQL developer? Is there any settings needs to be done at my client workstation?

Oracle database version is : 10G.
When we try to query a column from a table the output is shown as "?????". Seems the data in that column is stored in a different character set, which is not recognised while displaying the output. The column size is 35byte.
The nls parameter table shows the character set as "we8mswin1252".
get this issue resolved.

I'm trying to insert a character from the extended ascii character set. Specifically, there's a company that has an accented e (�) in the name. Right now, the company name doesn't have the e at all, accent or no accent. So I'm trying to do an update, something like
update table1 set company_name='blah�" where company='blah'
It runs, but doesn't do the update. Even when I try to forcefully do an insert (instead of an update) I get nowhere; the accented is simply dropped. So the basic question is, how do you insert extended ascii characters into oracle?

I am using C++ OCI LIB, to insert some report data from remote OCI client to oracle 11 server. This data is read by another process to create the report.The DB CHARSET is UTF-8. But the report tool expects the data to be ISO08859-1 encoded. So while inserting the data into the database i specify the following LANG and CHARSET for my table colulmn in client:
The TARGET DB CHARSET is UTF-8
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
size_t csid = 871; // UTF-8
OCIAtrSet((void *) bnd1p, (ub4) OCI_HTYPE_BIND,
*(void *)&csid*,
(ub4) 0,
(ub4)OCI_ATTR_CHARSET_ID, errhp);
This solution works for almost every case of ASCII and Extended ASCII Charest but we are facing issues if we have few specific characters to be inserted.f we are trying to insert single beta character [β] through client, the data goes empty to the column.
Beta Character details:
DEC OCT HEX BIN Symbol Description
223 337 DF 11011111 ß Latin small letter sharp s - ess-zed
DB Output after insert single β:
select rawtohex(NAME) from PERSONS where EID=333;
RAWTOHEX(NAME)
---------------------------
But if the string is *"ββ"* everything work fine:
DB Output for "ββ":
select rawtohex(NAME) from PERSONS where EID=333;
RAWTOHEX(NAME)
---------------------------
DFDF
