Dec 21, 2012I have a table with structure as:
CREATE TABLE XML_TABLE_1
(
ID NUMBER NOT NULL,
SOURCE VARCHAR2(255 CHAR) NOT NULL,
XML_TEXT SYS.XMLTYPE,
CREATION_DATE TIMESTAMP(6) NOT NULL
[code].....
- So HOW do I find the total size occupied by this table. Does BINARY storage work as LOB storage. i.e. I need to consider USER_LOBS as well for this. OR foll. will work
select segment_name as tablename, sum(bytes/ (1024 * 1024 * 1024 )) as tablesize_in_GB
From dba_segments
where segment_name = 'XML_TABLE_1'
and OWNER = 'SCHEMANAME'
group by segment_name ;
- Also if I am copying it to another table of same structure as:
Insert /*+ append */ into XML_TABLE_2 Select * from XML_TABLE_1.
Then how much space in ROllbackSegment do I need. Is it equal to the size of the table XML_TABLE_1?

View 3 Replies View RelatedSQL & PL/SQL :: Regular Table Or Materialized View - Clone Table Data In Another Database
Jul 19, 2010 There is a requirement to make a table data in a database (eg: HR database) available in another database (eg: EMP database), instead of accessing it using database link. In EMP database(where data needs to be cloned), data will only be queried and no write operation will be done. Data in remote database (eg: HR DATABASE) will be occassionally fully truncated and reinserted. The plan is to do a similar truncate and reinsert of data (from HR database) into EMP database monthly once using dbms scheduler job. So basically data in just one table needs to be cloned in another database.
Question: For this situation, is a regular table or Materialized view the right choice to clone the table in EMP database and why? The table in HR database (remote database) is not very big.

Table / View V$database Not Found In PL/SQL Function
Feb 18, 2011I'm trying to create a function that simply returns the current database name (e.g: select db_unique_name FROM v$database ) from a function but when I compile it comes up with :

Database Block And Cache Size
Oct 5, 2010In Oracle 9i
I know that db_block_size defines the standard/default block size for my datafiles.
I know db_cache_size defines the size of the my default database buffer of the size of my standard/default block size.
db_block_size = 8192 (8k)
db_cache_size = 200Mo of 8k block
Is there any needs for the other buffer cache
db_16k_cache_size
db_4k_cache_size
db_32k_cache_size
and so on?
If I have NO datafiles other than of the default block size, would I need to define a size for those other buffer pool? Is there any process that would benifit of these pools?

Nov 28, 2012We have Employee table, there is a field name Employee_no. field size is 6.can we restrict some one not to increase or decrease the field size of Employee_no. even User has admin role.

field_type: Varchar2
When we enter Employee no A000001(7 digit) then database not allowed to update because its field size is 6 characters we want to restrict admin user in Toad or SQL Plus 8.0 because he is Toad and SQL Plus user.
