I have tried the following SQL:
SELECT * FROM all_objects
But it also update LAST_DDL_TIME column of above table whenever any table grant is given any other schema.
I want Last DDL update time for table Alter only.
Ketan, I think DDL Triggers will solve your problems.
Find out more on this : http://www.dba-oracle.com/t_ddl_triggers.htm
If you use trigger to monitor DDL, you are essentially replicating functionality already provided through Oracle Auditing.
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_4007.htm
There is 10g-related guidance here: https://oracle-base.com/articles/10g/auditing-10gr2
You can try this:
SELECT object_name, object_type, last_ddl_time
FROM dba_objects
WHERE owner = <<table owners name>>
AND object_name = 'yourTableName'

I need to identify which tables in my schema are Global Temporary Tables.
Following script returns names of all my tables, but I am not able to identify which of these are GTTs and which are not.
SELECT OBJECT_NAME
FROM ALL_OBJECTS
WHERE OBJECT_TYPE IN ('TABLE')
AND OWNER='owner_name';
Thank you!
You can use ALL_TABLES
select table_name
from all_tables
where TEMPORARY = 'Y'
AND OWNER='owner_name';
Temporary column indicates whether the table is temporary (Y) or not (N)
I'm an Oracle11XE user with privileges to create and drop tables and procedures. I create a few tables, then while visiting the restroom, MIB zap me with a memory wipe (I foolishly looked into the light). Returning to sit at my workstation, I realize I need to query the database with my regular user privs, and figure out what that table or tables I created and the DBA has mysteriously gone missing.
You can use USER_TABLES view to get all the tables currently in your schema:
select table_name
from user_tables
If, additionally, you are interested in knowing when the tables were created, then you can use the USER_OBJECTS view where OBJECT_TYPE = 'TABLE'. That view includes the CREATED column.
select object_name, created
from user_objects
where object_type = 'TABLE'
I want to find the recently added column to existing table.
How to find recently added column in table or database(oracle).
Recently the table and the databases of our web application got modified and some of the table got altered.
Ideally you should have restricted access to your Production database, together with a build process which applies scripts out of source control, rather than allowing people to change things using TOAD. It's pretty hard to conduct forensics in a free-fire zone.
You can find out which tables have changed by interrogating the data dictionary:
SQL> select object_name from user_objects t
2 where t.object_type = 'TABLE'
3 and t.last_ddl_time > trunc(sysdate)
4 /
no rows selected
SQL> alter table t23 add col_3 number
2 /
Table altered.
SQL> select object_name from user_objects t
2 where t.object_type = 'TABLE'
3 and t.last_ddl_time > trunc(sysdate)
4 /
OBJECT_NAME
----------------------------------------------------------
T23
SQL>
This won't tell you what the change was, or who did it. To get better information you need a proper audit trail. At the very least you should enable auditing of DDL statements....
SQL> audit ALTER TABLE;
Audit succeeded.

I put this code into SQL Developer's Worksheet:
CREATE TRIGGER T_testDSNa
before INSERT
on testDSNa
referencing new as new
for each ROW
BEGIN
SELECT S_testDSN.nextval INTO :NEW.SYSID FROM dual;
END;
I get this:
Error report -
ORA-00942: table or view does not exist
00942. 00000 - "table or view does not exist"
*Cause:
*Action:
Would anyone know why? This has worked for 3 previous tables until I tried to run the DDL to create a 4th. Alternatively, is there a better way to set up an autoincrementing PK?
The problem was lack of schema. Oracle Definition of a schema :
Collection of database objects, including logical structures such as
tables, views, sequences, stored procedures, synonyms, indexes,
clusters, and database links. A schema has the name of the user who
controls it.
If you want to know the objects accessible without alias. You have to look on [USER_OBJECTS]. Which describes the relational objects owned by the current user :
SELECT
OBJECT_NAME
, OBJECT_TYPE
, LAST_DDL_TIME
FROM USER_OBJECTS;
If you want to know the objects accessible to the current user :
SELECT
OWNER
, OBJECT_NAME
, OBJECT_TYPE
, LAST_DDL_TIME
FROM ALL_OBJECTS;
In your case to see your objects in the list of available tables you need:
SELECT * FROM ALL_OBJECTS WHERE OWNER = 'USER';
You can also alter the session to avoid alias :
ALTER SESSION SET current_schema = User;
For priviliges/ roles views you can look at :
SELECT * FROM USER_SYS_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;
The last method but not the most secure to avoid alias. Is to log on with a user that has the same name as the schema.
Hoping that it can help
I was getting the same issue.
Solution: What I observed that my table which I created was surrounded by double quotes, which made it case sensitive.
So for each time I refer to my table, I need to surround it by double quotes.
CREATE TRIGGER T_testDSNa
before INSERT
on "testDSNa"
referencing new as new
for each ROW
BEGIN
SELECT S_testDSN.nextval INTO :NEW.SYSID FROM dual;
END;
refer this link: What exactly do quotation marks around the table name do?
I am trying to export data in oracle 11g
exp user/password file=dump.dmp tables = (table1)
via sqlplus.
And i get the following error:
About to export specified tables via Conventional Path ...
EXP-00011: USER.TABLE1 does not exist Export terminated
successfully with warnings.
But when i check who is the owner of this table:
SELECT owner, table_name from dba_tables where table_name = 'TABLE1';
I get that the owner of TABLE1 is USER
What should i do to export this table?
UPDATE
Actually, i found a solution. I hope it will help someone else.
Since version 11g Oracle has introduced new feature that is called deferred segment creation. Thus oracle doesn't create table segment if there are now rows in it. So i recreated my table with option 'segment creation immediate'
Actually, i found a solution. I hope it will help someone else. Since version 11g Oracle has introduced new feature that is called deferred segment creation. Thus oracle doesn't create table segment if there are no rows in it. And my table didn't contain any data. So i recreated my table with option 'segment creation immediate'
The solution was found here. There are more options how to fix the problem and an explanation why this thing happens to be in oracle 11g. :)
In addition to the posted answer from Olivia i would like to add some code:
SELECT 'alter table ' || table_name || ' allocate extent;'
from dba_tables where SEGMENT_CREATED = 'NO';
Execute the output and exp again. Your schema will be exported including empty tables.
EDIT:
similar question here, maybe you'll find your solution there.
Change this:
exp user/password file=dump.dmp tables = (table1);
to this:
exp user/password tables = (table1) file=dump.dmp;
You Can Use below query to take table level export from specific user.
exp user/password file=dump.dmp tables = user.table1
