There was one constraint define on the column of table that the value of column should be in range of 100 to 200. Some one has deleted the constraint. Is it possible to get the exact name of constraint from any system table.

How to validate a sum of some records in a table to be exact value?
I want to guarantee that sum(val_column)=100 at database level. Check constraints out of question. Trigger before update statement disable any update to that column when incrementing one row and decrement another... (unless with for all...)
I must admit my "google skills" have failed me and it is possible that I might be missing something obvious here but allow me to explain.
If I have a table that is populated/accessed by a typical OLTP application such that over time the data in the table may become "fragmented".
I know that is a very controversial term I used but that is not the question here. A simple way to describe the state of the table might be that the table has always been populated with lots of small INSERTs, modified with lots of small UPDATEs and data has been deleted in small DELETEs.
This has meant that the data is neither closely stored in data blocks nor is in any particular order (so there are some empty blocks under HWM).
Now my question is how do I create exact copy of this table and its indexes AS THEY EXIST AT THE MOMENT that includes
1) its data
2) its constraints/indexes etc.
3) its storage parameters
4) data stored in EXACTLY same manner as in original table.
To avoid complications, the table in question is just a normal heap table without any partitioning involved. While
CREATE TABLE AS SELECT (or CREATE TABLE followed by INSERT) will take care of points (1) to (3) above, it will not achieve point (4) above.
I need to check the exact amount of space used (in bytes or MB) by a table which is having a BLOB column.I tried the following query but it is not giving the proper usage.
select segment_name , sum(bytes)from dba_extentswhere segment_type='TABLE'and segment_name in ('TEST_CLOB','TEST_BLOB','TEST_CLOB_ADV','TEST_BLOB_ADV') group by segment_name; I even tried the following stored procedure create or replace procedure sp_get_table_size (p_table_name varchar2)as l_segment_name varchar2(30); l_segment_size_blocks number; l_segment_size_bytes number; l_used_blocks number; l_used_bytes number; l_expired_blocks number; l_expired_bytes number; l_unexpired_blocks number; l_unexpired_bytes number; begin select
[code].......
But it is giving the error
Error starting at line 298 in command:exec sp_get_table_size ('TEST_CLOB_ADV')Error report:ORA-03213: Invalid Lob Segment Name for DBMS_SPACE packageORA-06512: at "SYS.DBMS_SPACE", line 210ORA-06512: at "SYS.SP_GET_TABLE_SIZE", line 20ORA-06512: at line 103213. 00000 - "Invalid Lob Segment Name for DBMS_SPACE package"*Cause: The Lob Segment specified in the DBMS_SPACE operation does not exist.

how to i insert a constraint of words into the table example below.I am new to this stuff man.
Create table Orders
(
orderID Number(8) Primary Key,
orderDate Date Not Null,
methPmt Varchar2(10),
custID Number(5),
orderSource Number(2),
Foreign Key(custID) Reference Customer(custID),
Foreign Key(ordersource) Reference OrderSource(ordersource)
);
The catch is I am required to enter a constraint of the methPmt will only take values of "CASH", "CREDIT" or "CHEQUE" only.
How am I suppose to enter this constraint value into the creation of this table?

I use Oracle 10.0.2.0.1.If I create a table with constraint key; after that I create an unique index key, I got an error. Does it mean when I create a table with constraint the unique index are automatically created and I could not create index key as I did as below?

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.

I have created a table below, my TL asked me to create a local unique constraint for the below table.
I went through all sites and could not find the correct solution, how to create LOCAL UNIQUE CONSTRAINT ON SUB PARTITION TABLE and LOCAL UNIQUE INDEX ON PARTITION TABLE. Creating Local Unique constraint should take care of creating local unique index creation.
