SQL & PL/SQL :: Using Clob Instead Of Varchar2
Mar 23, 2010in our application we are using clob column instead of varchar2 because varchar2 does not allow more that 4000 chars, so Using clob allows to put data of any length, will it cause performance issues ? we have this column in almost in all tables .

Server Utilities :: CLOB Inserted As Varchar2
Oct 16, 2010I ave a few fields in my flat file which might be a CLOB (not sure how the source is storing the data - need to check on that.) I am trying to load this data into my table column which is a varchar2(4000) . I am able to insert most of the data but few records are rejected because of Field too long error....
While debugging the problm I manually copied the field from flatfile and inserted into my table - bingo it worked. (The field was not more than 1000 bytes - only a few lines of information ) My question: When a field is not more than 1000 bytes why couldnt it get inserted as a varchar2?
Note : I cannot make the table column as CLOB because the problem is not with just one column - I have 10 fields which have this problem . So its not advisable to have 10 CLOB fields in the table......
I have specified OPTIONS (BINDSIZE=256000,READSIZE=256000,ROWS=1)

PL/SQL :: Convert CLOB With WE8ISO8859P15 Charset To UTF-8 Charset
Jun 28, 2013I have a CLOB containing a XML code and all XML tags where created using the DB charset: WE8ISO8859P15.
For example:
{code}
<?xml version="1.0" encoding="ISO-8859-1"?>
<certidao xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<funcionario>
[Code]...
I need to maintain this charset value.
But now I need to convert all my CLOB data into UTF-8 charset for external requirements and stored this new CLOB in a table column.
I can't change the charset of the session. I've tried to use a function
{code}
FUNCTION convert_xml (pcl_xml IN CLOB)
RETURN CLOB
[Code]....
This function apparently works, but when I try to validate the XML content (after I replace the encoding="ISO-8859-1" to encoding="UTF-8") the validation software tells me that I have some characters that should not be present in a file using UTF-8 encoding.

10g - Some VARCHAR2 Fields Empty?
Jul 21, 2011Once a year in the application we have a specific query that gets used a lot. It's an UPDATE that updates a single record in a single table with a few different datatypes, but the issue is happening with one of the VARCHAR2 fields. It updates one VARCHAR2(2000) and three VARCHAR2(4000) fields at the same time.
This year, 9 of the 95 times it was used resulted in one of the VARCHAR2(4000) fields as null in the database. The users would not want this field to be null and 5 of the 9 have told us they entered something (the form they're filling out is a research proposal and leaving this field empty would be pointless because it's part of the funding request, so they're not doing it). The application isn't doing it because it's not consistent. I've checked the application and these fields can't be nulled any other way.
We just found the issue so I looked back over the past years back to 2005. Last year it didn't happen at all. In 2010 it happened a handful of times. Some years there were even more times. It's not always the same field but it's always a VARCHAR2 of at least 2000 characters.
I have a lot more information but it's all just details (let me know if you need to know more). I'm wondering if there is a bug in 10g with these types of fields. I don't believe it's malicious behavior on an individual's part but I suppose that's always possible.
how to research something like this. I tried to get access to Oracle Support and the Knowledge Base I heard they have but it doesn't look like I can do that
