SQL & PL/SQL :: Data Of Column Is Large - How To Insert
Oct 9, 2013
I have encountered some problems in SQL I want to create a table with a bunch of prepared data. For ease of use, I choose to generate a SQL file which contains all the sql clauses used to create the table and insert the data. So all the data can only be inserted to a table using sql clause.
My questions:
1) If data of a column is large (for example, 1 M text), how to insert it using SQL, is there a piecewise method.
2) And how can I insert BLOB data using SQL clause.
What I what is to enclose all the operations in a single SQL file, and when the table is needed, just execute this SQL file.

I'm looking for a way to insert strings larger than 40.000 characters in a CLOB-field without geting the "ORA-01461: can bind a LONG value only for insert into a LONG column".
Something like this:
insert into MyClobTable(ID,Data) values ('101','A string containing more than 40000 characters...')
The problem is that a Java-application concatinates the string from a MSSQL-DB so I don't store the string in my oracle-DB. As far as I'm aware this means I can't chop my string in pieces and use declare to put the pieces in variables, right?
Below is an example I found but I don't think I can apply it on my case, correct?
SQL> CREATE TABLE myClob
2 (id NUMBER PRIMARY KEY,
3 clob_data CLOB);
Table created.
SQL>
SQL> INSERT INTO myClob VALUES (101,null);
1 row created.
SQL>
SQL> declare
2 clob_pointer CLOB;
3 v_buf VARCHAR2(1000);
4 Amount BINARY_INTEGER :=1000;
[Code]...
PL/SQL procedure successfully completed.
SQL>
SQL> drop table myClob;
Table dropped.
SQL>

1. When querying the "alert_log" table I created from the alert log using the script below, 2 new files were created ALERT_LOG_30499.bad and ALERT_LOG_30499.log.
The ALERT_LOG_30499.log. contains this error message:
error processing column MSG in row 2910 for datafile /u02/damistst/admin/bdump/alert_damistst.log
ORA-12899: value too large for column MSG (actual: 82, maximum: 80)
the ALERT_LOG_30499.bad , so far, only contains datafile resize information. The datafiles have plenty of space and there is plenty of space on the San slice the datafiles reside.
2. then each time I recreate the table and increased the increased the varchar2 size, the "actual" size will also increase in the log file.
error processing column MSG in row 2910 for datafile /u02/damistst/admin/bdump/alert_damistst.log ORA-12899: value too large for column MSG (actual: 92, maximum: 90)
3. When I increased the varchar2 size to 120+ it gave me this error message:
[oracle@tds_dw bdump]$ cat ALERT_LOG_30715.log
LOG file opened at 03/09/11 14:46:20
Field Definitions for table ALERT_LOG
Record format DELIMITED BY NEWLINE
Data in file has same endianness as the platform
Rows with all null fields are accepted
Fields in Data Source:
MSG CHAR (255)
Terminated by ","
Trim whitespace same as SQL Loader
TABLE DDL:
create table
alert_log ( msg varchar2(80) )
organization external (
type oracle_loader
default directory BDUMP
access parameters (
records delimited by newline
)
location('alert_damistst.log')
)
reject limit 1000;
**** QUESTION
I can still query the alert_log table in sqlplus, but those log and bad files are generated, is this an issue?
example of a piece of the results from " select * from alert_log; "
MSG

I want to add column to table which has huge amount of data and fill with data from another table. What is the best way to do it? Is it faster to use CTAS instead of ALTER TABLE ADD COLUMN?

I am considering all of the capabilities and benefits of using Data Pump for exporting and importing extremely large data files. Would like to know if importing to tape is possible? If so, would the data be accessible if needed later?

I have oracle 11gr2 database on linux os. It's total sga size is 500mb only. Now, if uses wants read the 1gb of data from database, then there is no sufficient memory in buffer cache. so how it will works. the transaction will get successful or it will fail.And i have another doubt, does oracle can read the data from memory only or it can also read directly from disk.

Since XML-files only contain character data, we could/should store it in a CLOB, rather than a BLOB.
But, One of my friend having a table where a column is defined as bloband came to know that XML data are being stored. I searched for some article with keyword 'How to insert large XML data in BLOB' But did not work.How to store the large xml content in a Blob and How to extract it?

I am facing a problem with utl_http.write_text in my pl/sql application. My requirement is to write data of size>32k. So I used a clob variable in write_text. But still it is showing numeric or value error when the data size is above 8k.
I have read that chunked transfer encoding will work. But I couldn't find out how this is done.

I have a query on , how to view the sample data from a very table which is large in size ( more than 10 million ).
I just need to see some sample data from a large table ( to see what kind of data which is application related ).
My question is :
Select *

where rownum < 10
is this a Good way to view the sample data ?
I have understanidng that the rownum will be assigined to the rows once all the rows are reteived.
So what is the best way to view ?..I am not sure of any condition to put in the intial time of querying.

Scenario:
Our application is using a two instance, one for the live active data and the other for the reports data. We have a process which moves the data from the live instance to reports instance every night. In a single db environment the process is working without any issues. However when we move to the RAC environment the reports db's (insert) in large table get locked and we are unable to insert data to the reports db.
What we are performing is:
Insert into my_table_rpt select * from may_table_live@db_link_to_livedb;
Issues:
my_table_rpt get locked
We have found the workaround by disable locking in destination and subsequent to the insert enable locking
ALTER TABLE my_table_rpt DISABLE TABLE LOCK;
Insert the data to the reports database table
Then
ALTER TABLE my_table_rpt ENABLE TABLE LOCK
Question:
Why does the large destination table (my_table_rpt) get locked in the RAC environment?

We have data archive scripts, these scripts move data for a date range to a different table. so the script has two parts first copy data from original table to archive table; and second delete copied rows from the original table. The first part is executing very fast but the deletion is taking too long i.e. around 2-3 hours. The customer analysed the delete query and are saying the script is not using index and is going into full table scan. but the predicate itself is the primary key,More info below
CREATE TABLE "APP"."MON_TXNS" ( "ID_TXN" NUMBER(12,0) NOT NULL ENABLE, "BOL_IS_CANCELLED" VARCHAR2(1 BYTE) DEFAULT 'N' NOT NULL ENABLE, "ID_PAYER" NUMBER(12,0), "ID_PAYER_PI" NUMBER(12,0), "ID_PAYEE" NUMBER(12,0), "ID_PAYEE_PI" NUMBER(12,0), "ID_CURRENCY" CHAR(3 BYTE) NOT NULL ENABLE, "STR_TEXT" VARCHAR2(60 CHAR), "DAT_MERCHANT_TIMESTAMP" DATE, "STR_MERCHANT_ORDER_ID" VARCHAR2(30 BYTE), "DAT_EXPIRATION" DATE, "DAT_CREATION" DATE, "STR_USER_CREATION" VARCHAR2(30 CHAR), "DAT_LAST_UPDATE"

Data is first moved to table in schema3.OTW. and then we are deleting all the rows in otw from original table. below is the explain plan for delete

I have the following tables:
CREATE TABLE test_abc(id NUMBER PRIMARY KEY, col1 NUMBER(10), col2 NUMBER(10), col3 NUMBER(10));
INSERT ALL
INTO test_abc VALUES (1,12345,34567,87654)
INTO test_abc VALUES (2,17345,37567,87754)
INTO test_abc VALUES (3,12745,34767,87674)
INTO test_abc VALUES (4,17045,30567,80754)
INTO test_abc VALUES (5,12740,34067,87604)
SELECT * FROM dual;
CREATE TABLE test_b (id NUMBER, col VARCHAR2(10), coltype_id NUMBER);
What I need to do is to convert the columns col1, clo2, col3 in test_abs into rows in test_b. but I need to do this so that the column name is what determines the value of colytype_id.So in test_b values will look like:
id col coltype
1 12345 1
1 34567 2
1 87654 3
and so on.

I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.

how to avoid this and get the select query to store as
