SQL & PL/SQL :: Import CSV In Clob To Table
Aug 10, 2012
I'm trying to import data from a csv file format which is located in a CLOB column in a single record in the database. I want to import the data that is contained in this CLOB into a table. I am having limited success using JH_UTIL. Here's the script that I am running (which works):
set serveroutput on;
declare
v_lines jh_util.stringlist_t;
v_values jh_util.stringlist_t;
begin
for rec in (select 1 id, ac.clob_content csv
[code].......
The problem is when the file gets too big, I get a the following error:
Error report:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at line 6
06502. 00000 - "PL/SQL: numeric or value error%s"
*Cause:
*Action:
I assume this means because the file size is too big. Is there any way to process larger "files" (CLOB data)

by using below command:
expdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log
after that i zip that dump and move it to external usb and now i need that table i copy that table and unzip that that dump
Command i am using to do the import is :
impdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=impdpEMP_DEPT.log
But the query of import is still runing even not showing any amount of rows to be imported.
i already make the tablespace in which the table was previosuly before dropping but when i check the sapce of tablespace that is also not consuming one error i got preiviously while performing this task is:
Connected to: Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production

I am trying to migrate a table to a new table that has the field sequence changed and also has a new field added. My main question is if it is possible to have datapump add values to the new field in the target table.For example:
-original table has fields a, b, d, c
-new table has fields b, c, d, a, e
I want to load the new table and also include adding values for field e. In this case, field e is a year field, so it should be loaded with '2012'..Does datapump have the ability to do this? Is reorganizing the fields going to cause me any problems? We are on oracle version 11.2.0.3

I am more of a C/C++ guy and relatively amateur in oracle. I have to update a table field from "Long" to "CLOB". I have planned to do a simple alter table, and as far as I know there won't be any issues.
Queries:
1. Although I have triple checked, is there any scenario under which there can be any data loss during the data type change? The data is very critical and no data loss can be entertained.
2. Is there any easy way to update all the related views without having to do so manually?
3. Any particular precautions I should take before introducing the change?

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 have a table that contains a CLOB column with pseudo-XML in it. I want to keep this data in an XMLType column so that I can leverage some of Oracle's built-in XML features to parse it more easily.
The source table is defined as: CREATE TABLE "TSS_SRM_CBEBRE_LOGS_V" ( "INCIDENT_ID" NUMBER, "EVENT_TYPE" VARCHAR2(100 BYTE) NOT NULL ENABLE, "EVENT_KEY" VARCHAR2(100 BYTE), "CREATION_DATE" TIMESTAMP (6) NOT NULL ENABLE, "CREATED_BY" VARCHAR2(100 BYTE) NOT NULL ENABLE, "LOG_MSG" CLOB);
The target (for testing this problem) table is defined as: CREATE TABLE "TESTME" ( "LOG_MSG" "XMLTYPE") My query is: insert /*+ APPEND */ into testme ("LOG_MSG")select XMLTYPE.createXML("LOG_MSG") as LOG_MSG from "TSS_SRM_CBEBRE_LOGS_V" b; In SQL*Developer, my error is: Error report:SQL Error: No more data to read from socket In SQL*PLUS and Toad, my error is: ORA-03113: end-of-file on communication channelProcess ID: 13903Session ID: 414 Serial number: 32739

I want to load data to a table and from a simple file text, using a Vb.net application which will connect to a oracle 10g , or a SqlServer or a MySql database, depending the params.
When i connect to a SqlServer Database i use the sql command "BULK INSERT CODPOSTAL2 FROM file.txt with( DATAFILETYPE = 'char',FIELDTERMINATOR = ';', ROWTERMINATOR = '
')"m" and it works fine.
With a DB Mysql i use "LOAD DATA INFILE file.txt INTO TABLE CODPOSTAL2 FIELDS TERMINATED BY ';''" and also works.
My problem is with Oracle. I tried the same example as MySql, but it gaves the error "wrong" ou "unknown command". I also tried in Sql*Plus but it seems to not recognised the command "LOAD".
Another thing, i can't use the Oracle Loader, it must be like this.

We have a table in Oracle9i database with around 14 million records and we would like to import that table into 10g database with similar structure. We have exported the table from 9i database and would like to import the table into 10g database within same schema name with different table name as we already have the table with same name in 10g database in same schema. Is it possible to import a table with different table name?
We have a way around to import the table into 10g database in another schema and then push the data into our main table but want to know whether the above requirement is possible.

I have a table as below. This table is not partitioned.
create table t1
(
d1 date,
n1 number not null
);
[Code]....
I took an export dump of the above table and after that I renamed the table t1 to t1_old. Then I recreated the table as below with a default constraint on d1 field.
create table t1
(
d1 date default to_date('01/01/1100','DD/MM/YYYY','NLS_CALENDAR=GREGORIAN'),
n1 number not null
[Code]....
But the problem here is the data import is taking too much time than what I expected. I can't afford a maxvalue partition here as of my DBA team mentioned if you add maxvalue partition adding partition later in a stage is difficult on this table
apply in this scenario and make the import faster. I am using oracle 10.2.0.1.0 version.

1) what is the harm apart from the below listed? if I'm not using the index, eventhough it exists.
Lets say, I've index on salary column, and I'm using "select * from employees;"
Harms:
A) It takes more cpu resource to compress the bitmap format for the index value (incase of insertion).
B) Hope there is no extra effort need for update the value of indexed column's value.
2) Eventhough if I'm not using the index, the above restriction will applicable for the index column normally (?) Then how we can say unused index column is causing the performance issue.
3) if you say index has positives and negatives, then playing with the index (adding and removing as frequent as we need) is also not a solution. Am I right.So in overall we have to accept the negatives of the index.
