I 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)
in 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 .
I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data. I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.
I got html source code inserted into the table as CLOB (or BLOB). And I would like to search a some word from that.When I find a some value I can write this one into the column.It would be easy if this code is xml but isnt.
I need to create a composite unique index on varchar2, number and CLOB column. I haven't used such index before that have the CLOB column indexing. I found the below link related to CLOB indexing...
[URL]......
Links from where I can get related info. Also I would like to know the impact of such index on performance. I have to store and process around 50 million records in such a way, will it be beneficial to use this index?
I need to create a materialized view with a clob column based on a varchar2 column of a table.This is because in the mv the clob column data gets appended one after another.
How to load the CLOB data into table..in the attached file 18 column has clob data it's appear like new line..Using external table how to load. i tried it's not working..
i am fairly new in the oracle arena, but what would cause a statement such as
ALTER TABLE TEST_TABLE MODIFY text_field1 varchar2(100) DEFAULT 'testval' NULL
to change a column's type from VARCHAR2(100) to VARCHAR2(100 byte)? i found a few mentions of the 100 byte concept online but nothing that jumped out at me.
I'm trying to get size of CLOB column but not getting any output.

I want to load lakhs of records into a table. My problem is when after loading the ¼ of records my process is abend due to the size of my rollback segment area. I don't have an option to increase it. So, Is there any way to go for intermediate commits when I am using the imp or sqlldr utilities to load the entire data without abend?
I have a table with two clob columns and need to manually allocate space to the table and to its lob segment. Is the following command correct?
--to allocate extent to the table alter table emp allocate extent; --the table has columns named col1 and col2 which are clob --to allocate extents to the columns alter table emp modify lob (col1) (allocate extent (size 10m)) / alter table emp modify lob (col2) (allocate extent (size 10m)) /
I am familiar with tool Netca. However there is one more utility exist for the same functionatlty which is netmgrI checked with many DBAs for the exact difference, however I did not get the best answer from them. I also have checked in google but not exactly got the difference. list the exact difference between those 2 tools (netca, netmgr)
I have exported data of one user an importing into another schema at another server. when i am trying to imoport it is working fine for quite no of imports into tables, but after some time it starts giving me below mention error...

I have a requirement to read flat text file(around 15000 lines) residing at a client location from DB server and write into a table in One cell.
I tried UTL_FILE and DBMS_LOB but, i am not able to access client location to read the file as it reads path from Oracle Directory.
eg. my client path is 198.168.1.1 and my DB server is in unix say 192.168.1.10. file location is: \192.168.1.1shareabc.txt So I created One Oracle directory as MY_DIR having DIRECTORY_PATH as '\192.168.1.1share'. But both UTL_FILE and DBMS_LOB is not able to access the file.
Error Message: ------------- Unable to process CLOB -22288 ~ ORA-22288: file or LOB operation FILEOPEN failed No such file or directory
Few Details for reference: ------------------------- File Location: \192.168.1.1shareabc.txt Unix DB Server location: 192.168.1.10 Table : Test (filename varchar2(30), Content CLOB) Oracle Dir: MYDIR Directory_Path: \192.168.1.1share
I've a question regarding difference of character sets, while taking a export(logical backup) of database on directly to server(linux RHEL 2.1 AS) and export on a client (windows xp prof machine, where only a oracle 9i client is installed). On server it seems to fine and okay, but on client node i'm getting following error for almost all tables.
EXP-00091: Exporting questionable statistics.
My question is :
[1] Is it creating any sort of problem, if later on i import the data which was taken from client node.
[2] Why there is a difference(marginal) in dump(.dmp) file size.
[3] Is there any way to overcome it, or it is the natural behave of it. Means not a problem.
[4] If i'm using a long or blob as datatype for some of my table,is they have any problem if i persist like above.
Additional Information about character sets On server node :
Export done in US7ASCII character set and AL16UTF16 NCHAR character set server uses WE8ISO8859P1 character set (possible charset conversion)
On client node :
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set server uses US7ASCII character set (possible charset conversion)
load data infile 'trlc.csv' replace into table trlc fields TERMINATED BY '|' TRAILING NULLCOLS (est_no,right_no,maj_auth,weight,idm_ht,c_date,P_tkt)
The rows get inserted successfully. But the result sets are different, for example: When I do a select in SQL Server,'select len(weight) from trlc;' , I get the length as 0. But when I do a select in oracle database, I get the length as 1. Also, the result set varies for the query below:
select * from trlc where weight=' ';
(SQL Server returns 1 row but Oracle returns no rows)
Do I need to mention any conversion code for the weight field to accept ' ' value?
I've inherited a 10.2.0.1.0 instance running on a windows 2003 box; running fine, no problems other than system has been in production since 2005 and has gotten pretty old and tired. This old box has one tablespace on it... called "gateway".
I've installed 11.2.0.1 on a new (Windows 2008 R2 Enterprise 64-bit) server and created an empty database also called "gateway".
Now to move the data and views, objects, everything.
I've read up on a variety of migration techniques (oops, I mean "upgradation" LOL) and can follow the steps...
In short, I want to pull everything off of server a (10.2) and put it into production on server b (11.2). There seems to be quit a few options.
1. install 10.2 on my NEW server (server b), move the data over and get everything running, then install 11.2 and have it upgrade the database as part of the installation process. 2. drop the empty tablespace on server b, stop the database on server a, copy the files over from the old to the new home, run DBUA or set the compatibility attribute... 3. run some type of server a to server b utility that can bridge the two over the network. Some type of mirroring technique? 4. run file export scripts on server a, copy files to server b and run various import scripts
I tend to think that option 3 would be the best because both instances are in great health and are running right now. Is there a mechanism that allows the 11.2 instance to see and upgrade from a different server?
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
i m create a table emp . all user of database have privileged to read and write the emp table. now How can identify that which user have insert row in emp file ?
