Cannot drop a table

Hi Gurus,
when i am trying to drop a table, getting the below error:
ora - 00942; table or view does not exists
when am doing "desc <table_name>", i can see the structure.
tried to rename the table still its giving ora 00942
can you please suggest why the table cannot be dropped?
thanks in advance!

Try this as user TEST2:
SQL> select 'drop table "'||table_name||'" purge;' from user_tables where upper(TABLE_NAME) like 'SKF_%' ;
'DROPTABLE"'||TABLE_NAME||'"PURGE;'
drop table "SKF_CL_AL_ROW_AVAILABILITY " purge;
SQL> drop table "SKF_CL_AL_ROW_AVAILABILITY " purge;
There COULD be a blank (or something else) at the end of the table name.

Cannot drop the table - cannot enable compression - cannot find the object

Hi,
I'm trying to install Database Instance as a 2nd part of distributed SAP system. There was already MS SQL 2008 STD installed, I installed another MS SQL 2008 STD instance manually (as described in PI installation guide) from original MS SQL 2008 STD DVD, not one provided by SAP. The database is created by SAPinst, and we have a crash at the beginning of ABAP import phase:
Here is a log: -> http://wklej.org/id/392174/
I thought I can run development SAP system on Standard Edition. Am I right and this is just permission problem? How to troubleshoot that?
Thanks for any suggestions.
Regards,
K

Hi Sven,
Thanks, &norowcompression& did the trick!
Does anyone know is this type of installation (not SAP's MSSQL media, STD Edition for dev/qas system, MS SQL instance for SAP with another MS SQL instances on the same server) is supported?
Thanks again,
K
//edit:
no it's not supported:

Cannot drop table

Versions are Oracle 11.2.0.1.0 and SQL Developer 4.0.0.12 on Windows 7 Ultimate SP1.
Hi
I'm following the CBT Nuggets SQL Fundementals training (video #11) and cannot drop a table I have just created. The command executed and error are:
drop table newprods;
Error starting at line : 1 in command -
drop table newprods
Error report -
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-20000: Cannot drop object
ORA-06512: at line 2
00604. 00000 - "error occurred at recursive SQL level %s"
*Cause:    An error occurred while processing a recursive SQL statement
           (a statement applying to internal dictionary tables).
*Action:   If the situation described in the next error on the stack
           can be corrected, do so; otherwise contact Oracle Support.
As the HR user I created two tables and created a FK constraint between them. After truncating the table with this FK, I am unable to drop it. Even if I remove the FK, the error is the same. Issing the command in SQL*Plus gives the same error.
This is the first time I have created any tables since installing Oracle on this machine and is my first attempt at dropping a table. I have not created any sequences, triggers or views based on these newly created tables.
Does anyone have any ideas?
Cheers

Dropping Temp Tables

We are currently converting our student information system from Sybase to Oracle. My task is to convert our existing sql scripts. A number of them use temp tables and I have successfully got them to run except that I cannot drop the tables at the end of the script because they are still in use *[Error Code: 14452, SQL State: 72000] ORA-14452: attempt to create, alter or drop an index on temporary table already in use*. For example:
/* Oracle Version */
-- Select Cactus ID ------------------------------------------------------------
CREATE GLOBAL TEMPORARY TABLE tch1
(name Varchar(45), tid Int, CactusID Varchar(12))
ON COMMIT PRESERVE ROWS;
INSERT INTO tch1
SELECT

t.id teacherid,
c.value
FROM
teachers t
INNER JOIN customvarchars c ON t.id = c.KeyNo
AND fieldno = 148;
-- Select Core Codes ---------------------------------------------------------------
CREATE GLOBAL TEMPORARY TABLE crs1
(name Varchar(45), cid Int, CactusCd Varchar(12))
ON COMMIT PRESERVE ROWS;
INSERT INTO crs1
SELECT
cs.course_name,
cs.id courseid,
c.value
FROM
Courses cs
INNER JOIN customvarchars c ON cs.id = c.KeyNo
AND fieldno = 146;

-- Drop Tables -----------------------
DROP TABLE tch1;
DROP TABLE crs1;
I have an Oracle PL/SQL reference guide at hand, but I don't see any mention of dropping the tables when completed. I'm also curious if I'm using the terminator (;) correctly. MS SQL Server and Sybase did not require one.
Thanks.

How could I drop temporary table in preserve rows?

Hi,
I created a global temporary table test with the option, on commit preserve rows.
I try to drop it with another session but I can't, I always have the error message :
ORA-14452. So what can I do?
Thanks.

We cannot drop a temporary table if a session is using it. This means once a session has inserted data into it we cannot drop the table until that session either commits or exits (depending on whether the table is of the type PRESERVE ROWS). You can see this by looking in v$lock.
If you quit out of your first session the second session will be able to drop the table.

Remove an offline filegroup or drop a table residing in an offline filegroup

I restored a database with a primary filegroup backup only. Everything works fine except that when I tried to drop a table which is in another filegroup, I got "Cannot drop the table 'Imaging' because at least part of the table resides on an offline
filegroup.". Is there any way to remove an offline filegroup or drop a table residing in an offline filegroup?
Thank you for help.

Not in any supported way. If you were permitted to this, and the other filegroup later was restored, there would be an inconsistency.

How do i drop my table

Hi guys ,
am trying to drop my table . but it is used by another user . am getting error message.
can give a suggession .
Edited by: Balajiraam on Mar 2, 2011 1:33 AM

Hi,
You cannot drop the table without the other user completing the transaction on the table. So the user's transaction has to be completed before you drop the table. As hoek said the user should either commit or rollback the transaction.

ORA-20123 is a localized/customized error code & message; therefore any solution depends upon what is unique inside your DB now.
I suspect that some sort of TRIGGER exists, which throws posted error, but this is just idle speculation on my part.

Cannot drop column from table owned by SYS

Hello everybody,
How can I drop a column of table which is owned by sys? thanks!
Result as follows:
SQL> ALTER TABLE HELLO_TB DROP COLUMN NUM;
ALTER TABLE HELLO_TB DROP COLUMN NUM
ERROR at line 1:
ORA-12988: cannot drop column from table owned by SYS
newbie v

You can not 'change' the ownership.
You can, however, 'move' or 'clone' most objects by exporting and importing. As follows:
I create a table under SYS (shudder).
I then export it
- using userid SYS in this case,
- under normal circumstances I'd either use a DBA account or the owner's userid
- since I want a table, I use the TABLES option - a list is comma separated and in quotes
I then import it using a 'userid' switch - fromuser & touser options
- in this case from SYS to HR
Finally, I verify it was transported.

Cannot Drop table with lower case name

Hi,
One of my developer created a table through application in oracle 10g R2,
when I list tables
select * from tab;
the table name is shown in lower case or Initcap.
I cannot drop or manipulate that table.
How can I drop that table(s)?

use the same case what your table has used and put double quotes on both sides for example if your table is lower case use like:
DROP TABLE "your_table";HTH

I cannot "drop table"

Hi,
I've table BP:
CREATE TABLE BP (
BV_ID VARCHAR2 (32) DEFAULT NULL NOT NULL,
BP_ID VARCHAR2 (32) DEFAULT NULL NOT NULL,
CONSTRAINT BP_PK
PRIMARY KEY ( BV_ID, BP_ID )
BP has more 100 records:
Now I'd like to drop table BP:
drop table BP;
ORA-02449: unique/primary keys in table referenced by foreign keys
ALTER TABLE BP DISABLE CONSTRAINT BP_PK;
ORA-02297: cannot disable constraint (BP_PK) - dependencies exist
I tried disable all constraints with:
select 'alter table '||table_name||' disable constraints '||constraint_name||';'
from user_cons_columns
where column_name='BV_ID'
or column_name='BP_ID'
but when I try drop table BP;
ORA-02449: unique/primary keys in table referenced by foreign keys
also truncate table BP:
ORA-02266: unique/primary keys in table referenced by enabled foreign keys
How can I drop table BP and disable all referenced by enabled foreign keys on table BP?
Thanks!

Or you could disable the foreign key constraint refering to primary key on the table and then drop the PK and then drop the table

ORA-02303: cannot drop or replace a type with type or table dependents

What is the best way for me to proceed to get my CREATE OR REPLACE statement working ?
Thanks

Well you could move to 11g but I'd suggest a less drastic measure for now. Save the data, drop the table, reload the table.
But give serious consideration to Tom Kyte's advice about object tables: Don't use them. Instead use relational tables and object views.

ORA-12983: cannot drop all columns in a table

Hi,
I am creating a table with two columns.
I have modified a column as unused using ALTER statement.
After that i have tried to drop the another column by using ALTER statement.
But it throws an error ORA-12983: cannot drop all columns in a table.
is it not possible to achieve this via ALTER statement?
thanks

is there any other way to find the name of the columns which have been marked as unused?Don't think so, and you would not be able to do much about. You won't be able to reference it, you won't be able to un-unuse it, and you would even be able to add a new column having same name.
Why are you using SET UNUSED in the first place?

Cannot drop table (error ORA-00054)

I am trying to drop a table but get an "ORA-00054 Resource busy and acquire with NOWAIT specified". Previously I had created this table and run a join which I cancelled because it was taking too long and obviously not doing what I wanted. Now I can't get rid of the table, even with sysdba privileges and re-starting the machine running the database.
Can anyone help?

It looks like your table got locked. Do you see any locks in your database on this table? I also, suggest you to close or kill the session which was cancled due to long running join condition, as you said in your question.
