SQL & PL/SQL :: How Special Characters Got Inserted Into DB
Jul 9, 2013
We are using Release 11.2.0.3.0 of Oracle. I am having below special characters inserted into one of my columns, how this value got inserted, (what is the source) i need to track it down.
We dont have any audit trigger on this table to track one level below. As per JAVA guys this is uploaded through a file and the file is having well defined characters and no special characters for this column value also they uploaded the file again but its now going fine with no such special characters. So they put it on DBA's to find how special characters came into database?
Again the editor is not recognising all the characters , so i got the ASCII value for each of the characters in the string, its as below.
String - ‡Mw‹O--ggÑ ÆÔéÓÞ³ µmT¤O ˆÓ`ôiyïÎ!Ž
ASCII character is : ‡ ASCII Value Is : 14844065
ASCII character is : ‹ ASCII Value Is : 14844089
ASCII character is : -- ASCII Value Is : 14844052
ASCII character is : ASCII Value Is : 49793
ASCII character is : Ñ ASCII Value Is : 50065
create table test ( name varchar2(50), descd varchar2(50) ) insert into test values ('kethlin','da,dad!tyerx'); insert into test values ('tauwatson','#$dfegr'); insert into test values ('jennybrown','fsa!!trtw$ fda'); insert into test values ('tauwatson','#$dfegr ,try');
how do I get the first three characters and last three characters from name field and remove all the junk characters from descd field?
I have one column name party_name containing Korean Characters and English characters.Some of the English characters have different symbols.My requirement is to get the data and exclude those symbols but not Korean characters.
Already I used a function to replace special symbols with space.The function contains code based on ASCII values it works good but it filters Korean characters too.the attachment of the screenshot, When I double click the name it shows with some question mark.
I need to removed special characters (!, ", #, $, %, &, /, () from a string, i have a table with sll this special characters and words that i have to remove from the string.

how to remove these special characters like ' in the query string.
We have a table with an nvarchar column that we use to store product descriptions.
This field is maintained on a web form created with the htp package.
Whenever a special character is used (ie, the copyright symbol, trademark, etc), the value is stored correctly in the DB. I've verified this because if i query the value in sql developer, i do see the correct symbol.
However, pulling this piece of data out to display in a formtext box (for edit) replaces all the special characters with ?'s.
Our National Character Set value is set to UTF-8.
Is this being caused by our database character set? or is it a web design problem that i'm just not aware of.
I can post code snippets if this isn't enough info...but I was hoping it'd be fairly simple.
We are using dbms_crypto.hash to generate the MD5 hash value for a CLOB that will be sent to other feeder systems. The feeder systems validate the file by generating the MD5 hash value on their end and compare with the MD5 generated in Oracle and accept the file only if the MD5 hash value matches.
This is in Oracle 10.2.0.4.0. I have some blob records (delimited text uploads) with some diacritic characters in them, and the diacritics are being lost when I run CONVERTTOCLOB.
database character set is AMERICAN_AMERICA.AL32UTF8
as long as the password contains no special chars (namely semicolon) it works fine. but when I try to use special chars in the password It stops working, with an invalid username/password error.
i tried different variations of adding " (\") over the password, over the entire pwd=a;b or braces { but nothing seems to work.the thing is that using ODBC works! what I did was: open ODBC, go to System DSN tab, add "Oracle in instantclient11_1", then fill the following information:
Data source name: Anything TNS Service Name: //10.10.101.66:1521/orcl User ID: myUser
then i press test connection, enter the password "a;b" and it works!
I have this table column of varchar2 data type. I need to find out if it contains anything other than numbers or alphabets(basically to see if it contains any special characters in it).
I just need to fetch only those rows that has special characters. How do I get this?
I believe we need to use Translate function to get rid of special characters, But I would not be knowing what sort of special charecters which appear in the string, In that case how do I use Translate?
In my DB there are special characters are stored like "Świętochłowice". So in Unix script while extracting these characters, I have used export LANG="universal.UTF-8" in order to make it English. which works fine.
But my question is how to retain this special character intact as, it is in DB?
So in UNIX script export LANG="universal.UTF-8" sqlplus -s uname/pwd@hostname/schema << ENDSQL | sed -e "s/Connected.//" -e "/^$/d" set pagesize 0 feedback off verify off heading off echo off serveroutput on size 10000 spool /path/out.txt Select name from tablename where is=12; spool off; exit ENDSQL
Output is "Swietochlowice" (makes sense),but how to get the output as "Świętochłowice" which is in DB? I have tried different NLS_LANG option, but no success.

I am uploading the data file which is a .csv, into one of the tables.. Few columns of the data file, contains sentences in German - like- Lötstelle Zinnspritzer Zinnschluß .. and while loading the problem that i encounter is - it doesnt recognize the commas, and doesnt know where the field ends.. e.g., in this line 1540,Lötstelle Zinnspritzer Zinnschluß,solder short,45230,94885,0,0,0,0,0,0,0,0,0,0,0,0
sometimes it assumes comma after 1540,Lö,tstelle and then no commas till Lö, tstelle Zinnspritzer Zinnschlußsolder short,
and sometimes, the whole as one line Lötstelle Zinnspritzer Zinnschlußsolder short4523094885,0,0
I am seeing some trailing characters in the coloumn when we are inserting Blob. I am doing SQLBindParameter with SQL_C_BINARY and SQL_LONGVARBINARY as InputOutputType and ValueType respectively.Do you see any problem in this. I get this problem when I am running Oracle 11 g client on an Windows 2008 Server 64bit.When the same set of query is fired from Windows 2003 Server 32bit with Oracle 10g it works fine and no trailing character gets inserted.
The HTML code for the bracket character '[' is & # 91; (without spaces). In my SQL, I would like to convert the word [you into & # 91;you. Is there a way to do that?
I know that replace() will work, but with that you have to supply a list of chars to replace; I
PROCEDURE getrecordsForinspection(i_table_name in varchar2, i_thread_id in varchar2, i_max_count in number default null, o_results out sys_refcursor) AS v_sql varchar2(1000):= null;
begin v_sql := 'update '||'i_table_name||' set status = '||'''IN_PROCESS-'||i_thread_id||''''||' Where final_status = '||''''STATUS_ACCEPTED'''||' and ('||i_max_count||' is null or rownum <= '||i_max_count||');';
EXECUTE IMMEDIATE(v_sql); commit; end;
when I execute the above procedure it gives the following error.
ORA-00911: invalid character cause: Identifiers may not start with any ASCII characters other than letters and numbers.$#_ are also allowed after the first character. Identifiers enclosed by double quotes may contain any character other than a double quote. Alternative quotes(q'#....#') can not use spaces, tabs, or carriage returns as delimiters. For all other contexts, consult the SQL language reference Manual.
I think dynamic sql is not executed because of the pipe character in the sql statement.

Insert into table1 select val1,val2 from table2,table3 where table2.col2=table3.col2 and....(some more conditions)
I am working with Oracle 10g.This insert statement is called from a procedure for nearly 3000 to 4000 time.Now my problem is even though the select statement selects correct no. of rows but still it insert only 2 or 3 rows.Apart from it ,it's working fine for some cases i.e it insert the actual no. of rows that is being selected from the select statement.

I keep getting the "ORA-01401:inserted value too large for column". No biggie - I've dealt with this multiple times before (but obviously not enough in this instance).
The data being entered is a SINGLE digit number - a number like 1, 2 or 3 - nothing fancy, just a plain straight everyday single digit number. The field in question is / was set as field type "Integer". Now, there is no set field size for integers! - not in Oracle anyway. Since it wasn't happy, I decided I'll try field types of 'Number' and also "Varchar2" set to 10 bytes. I have deleted the column from the table and re-created it as well.
Here's the even more puzzling bit: I can INSERT data into this field, BUT I can not UPDATE the field with the exact same data. The data is being inserted from a csv file. The same exact csv file used to insert works, but the same data in the same file will not update only that particular column.
If I delete the specific column data from the csv file, all goes through fine. If I hard code the update for the field (eg SET field2 = '1' or even SET field2 = ' ') it still doesn't work. So I know it is not the csv file that is causing problems. I deleted all data from the csv file except the field in question - still no luck.
So after eliminating: 1. The field type 2. The field length 3. The data being inserted 4. The external source of the data
