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 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)

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 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.

I'm updating a large piece of legacy code that does the following type of insert:
INSERT INTO foo_temp
(id, varchar2_column)
SELECT id, varchar2_column
FROM foo;
We're changing varchar2_column to clob_column to accommodate text entries > 4000 characters. So I want to change the insert statement to something like:
INSERT INTO foo_temp
(id, clob_column)
SELECT id, clob_column
FROM foo;
This doesn't work, since clob_column stores the location of each text entry, rather than the actual content. But is there some way that I can achieve the insert with one call to a select statement, or do I need to select each individual record in foo, open the clob_column value, read it into a local variable and then write the content to the matching record in foo_temp?

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 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 have a table say test (test_data varchar2(100));
Now I will insert all types of records into the table varchar,number dates and then i will write q query to etch all those records only which has dates only
INSERT INTO test(1);
INSERT INTO test('ABC');
INSERT INTO test(SYSDATE);
INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY'));
INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY HH24:MI:SS'));

I have a table in oracle sql developer showing years, IDs and attendance etc I'm wanting to create a report based on this table but have encountered a problem with the years.
The years currently run from 2006 to 2009 and the problem is that some of the IDs are only present for say 2007 and 2008, thus leaving nothing for 2006 and 09. This in turn creates problems in the report.
What i would like to do is in the table, for each ID that is missing any years, is to insert a single row with just the ID and year so that in the report it will show a blank instead of nothing at all. So for the above example i would have numbers for 2007 and 2008 and for 2006 and 2009 there would just be a space.

create table stg1(x number, y number);
create table stg2(x number, y number);
create table stg(x number, y number);
I want to insert data from stg1, stg2 into stg
Instead of writing two insert statements, I want to write only one in a for loop to insert data into stg from stg1 and stg2
I tried this
begin
for i in 1..2 loop
insert into stg(x,y) select stgi.x, stgi.y from stgi;
end loop;
end;
it gives me table does not exist error:
so by stgi, i mean it should take stg1, stg2 etc

I have two tables with two columns of each table in my Oracle Version :Oracle 9.2.0.1.0
TEST22:
-----------
|sno |sname |
-----------
| | |
-----------
TEST22P:
---------------
| col1 | col2 |
|---------------|
| sno | 1 |
| sname | arun|
---------------
Required outcome is
TEST22:
----------
|no | name |
|----------|
|1 |arun |
----------
Also this should be applicable for more than one value in the column col2 of table TEST22P.
ex:-
TEST22P:
--------------------
|col1 | col2 |
|--------------------|
|sno | 1,2..n |
|sname | arun,ajay..n|
--------------------
I used decode & pivot insert for this,but the result is a failure.
SQL>INSERT INTO test22 (no,name) SELECT DECODE(col1,'n',col2),DECODE(col1,'name',col2) FROM test22p;
SQL>
sno sname
--------
1 null
null arun
AND
SQL> INSERT ALL
2 INTO test22 VALUES(no)
3 INTO test22 VALUES(name)
4 SELECT DECODE(col1,'n',col2),DECODE(col1,'name',col2) FROM test22p;

In my organization, I have a table and in that there is a column named "code".I want to restrict some insertion to that particular column. suppose that code column values are 12 and 1245 then i cant insert the value 12,1245, 1 ,124 and so on but i can insert 2 ,123,15,12456 and so on.
that means the new values should not be any substring of the existing data from left. making that column primary key and then I had a logic to compare the existing value which are longer than the new value and then to perform this.But dont know how to make it happen correctly.

I am trying to insert a column into a variable from a trigger.
Here is the code that i have:
CREATE OR REPLACE TRIGGER BUYER_after_update AFTER UPDATE ON buyer
FOR EACH ROW
DECLARE
v_key varchar2(10);
BEGIN
select ID into v_key from buyer;
insert into message_log_table (table_name, message_comments)
values
('Buyer', 'Buyer '||v_key||' has been updated');
end;
/
When I run the above I get the following compiler error:
[Error] ORA-00904 (6: 12): PL/SQL: ORA-00904: "ID": invalid identifier
Since ID is defined in my BUYER table I do not understand what the error means.
Here is my create table statement:
CREATE TABLE BUYER
(
ID VARCHAR(50) NOT NULL PRIMARY KEY,
FNAME VARCHAR(50) NOT NULL,
LNAME VARCHAR(50) NOT NULL,
ADDRESS VARCHAR(50) NOT NULL,
CITY VARCHAR(50) NOT NULL,
STATE VARCHAR(2) NOT NULL,
ZIP_CODE NUMBER(5) NOT NULL
