here's a tricky case on which 5 peoples including a DBA have been struggling on for days... I offer lifetime consideration to the one which will identify the root cause of the issue.
here it is:
Oracle Client: 10g
Oracle Server: 11g
We have 2 schemas and 1 user:
SCHEMA1
SCHEMA2
USER
We have 1 table 'TOTO' which is defined in SCHEMA1 (SCHEMA1.TOTO)
We have a private synonym of table 'TOTO', called 'TOTO' defined in SCHEMA2, created like this:
CREATE SYNONYM SCHEMA2.TOTO FOR SCHEMA1.TABLE1;
We have granted SELECT,UPDATE,DELETE,INSERT priviledges on "SCHEMA2.TOTO " (so on the synonym) to SCHEMA2 (so that any session ran from SCHEMA2 has access to the synonym table)
GRANT SELECT, UPDATE, DELETE, INSERT ON SCHEMA2.TOTO TO SCHEMA2;
Our application connects to the DB with USER, then directly switches to SCHEMA2:
ALTER SESSION SET CURRENT_SCHEMA=SCHEMA2;
Then after that, it tries to perform a select query on the synonym table WITHOUT prefixing the synonym name by SCHEMA1 (this is a constrain of the framework we use):
SELECT COL FROM TOTO;
Most of the times this query works successfully, which is what we expect since we have altered our session to SCHEMA2, by default that where the objects are looked.
But sometimes it fails, with an ORA-00942: table or view does not exist error.
I insist on the fact that between the time when it works and when it fails, nothing has changed, we've just restarted the application (which is of course re-connecting to the DB the same way at each startup).
We've been investigated with a DBA monitoring all the events on USER,SCHEMA1,SCHEMA2 hoping to find an external process modifying the GRANTS on one of thoses, between a success and a failure, but nothing changes. Yet, at some point, randomnly we get the ORA-00942 error, then we restart the application several times and it's back again...
Would someone have an idea or any suggestion/hint that could lead us to identify what we're missing here?
Many thanks for your help!
The grant should go to USER, not to SCHEMA2:
GRANT SELECT, UPDATE, DELETE, INSERT ON schema1.toto TO userxy;
This should solve the problem. If it doesn't, can you please post the result of
SELECT * FROM all_objects WHERE object_name='TOTO';

I worked on an App using my personal workspace. Exported the same and later installed it on a Developer Team workspace.
Several of my pages are getting the ORA-00942: table or view does not exist while running, which doesn't make sense since the tables do exist (I tested this using the 'SQL Commands' option).
Funny thing is that the same code I'm using is actually applied on a different app within the same workspace and it runs perfectly.
Is this normal behavior? Might be due to workspace's configuration?
Thanks!
It could be a "permissions" issue:
http://www.dba-oracle.com/sf_ora_00942_table_or_view_does_not_exist.htm
Answer: There are several common operations that cause a ORA-00942
error:
Table owner name not specified when logged-in as a non-creator of the table.
ORA-00942 on table import (imp or impdp).
ORA-00942 on materialized view refresh.
...
This ORA-00942 error on insert is common when the user you are
signed-on as does not have permission to see the table!
Either make the table public and grant DML privileges:
connect myuser/mypass
create public synonym testtable for myuser.testtable
grant insert, select, update, delete on mytable to public;
Also, review the various replies to this thread. For example:
https://stackoverflow.com/a/36165446/421195
Because this post is the top one found on stackoverflow when searching
for "ORA-00942: table or view does not exist insert", I want to
mention another possible cause of this error (at least in Oracle 12c):
a table uses a sequence to set a default value and the user executing
the insert query does not have select privilege on the sequence. This
was my problem and it took me an unnecessarily long time to figure it
out.
First thing I would check is the parsing schema for the application - see Shared Components -> Security Attributes.
If this is not the same between the two instances of your application, that's the likely explanation.
I get the a query file and commit it but I have to choose the schema before it, to not get the following error; do you have any idea how to do it?
Thanks for your interest.
INSERT INTO LEAD_ACTV_CONFIG (
*
ERROR at line 1:
ORA-00942: table or view does not exist
I don't know jenkins so I hope the following makes sense. Sorry if it does not.
In order for INSERT to work, you must be connected to a database (i.e. one of its users). That user should contain LEAD_ACTV_CONFIG table, or it must be available to it (which means that some other user, who owns it, has granted the current user access privileges).
Now, if LEAD_ACTV_CONFIG is your own table, then your INSERT INTO would work properly; you don't need any additional privileges as you own the table so you can do anything with it.
If it is someone else's table, then either precede table name with owner name, such as INSERT INTO littlefoot.lead_actv_config (as if I own it), or create a synonym for that table in your schema:
create synonym lead_actv_config for littlefoot.lead_actv_config;
and access it just as you've posted in your question: insert into lead_actv_config
I would simply like to allow a colleague to view and edit the Database I've created.
I've tried:
GRANT ALL on FISHTABLE to CDEMARES;
and it returned Grant succeeded but nothing changed for him and he still wasn't able to view my table.
I also tried
GRANT SELECT smahala.fishtable to cdemares#sole.nefsc.noaa.gov;
but that failed with SQL Error: ORA_00990: missing or invalid privilege.
Is my issue that I don't have the administrative authority to allow someone else to view my Oracle table? Any advice is appreciated, thanks.
Your colleague needs to prefix your table with your schema name, otherwise Oracle doesn't know where to look for it, e.g.:
select * from smahala.fishtable
If they don't do that, and simply try to use:
select * from fishtable
then Oracle will look for the table in their own schema, and then look for a view, or a private synonym, or a public synonym. Your colleague could create a synonym if they'll be accessing this table a lot (and they don't have their own table with the same name). It's also possible to change their session's current schema, but that will make it harder to see their own objects.
You can read more about object naming and how to refer to objects in the documentation.
SQL Developer allows you to browse objects in other schemas. If your colleague was connected when you granted the permissions, they can refresh the object list, or disconnect and reconnect. Either way they should then be abke to see your table under your schema.
(Your second grant statement is missing an on, and you can't grant permissions across a database link, if that's what you're trying to do.)
I have a situation where yesterday my code was working ok, but today I find that my code fails because a SQL query fails on my Oracle database. The query fails because the table used in the query does not exists. I am no Oracle expert so I am reaching out to you Oracle experts out there. Is there a way to see in a log file or log table when my table disappeared and who dropped my table?
Thanks
Depending on previous configuration one would hope that a production database would have auditing turned on. Try
select * from sys.AUD$
The audit table can log almost every user action including dropping tables or revoking grants but has to be configured.
Assuming you have the recyclebin turned on in your database, you might be able to restore the dropped table. As the user who owns the table, you can run this query:
select * from USER_RECYCLEBIN
or if you have SYS access you can check the query:
SELECT * from DBA_RECYCLEBIN;
Then as a user owns the table, run this FLASHBACK command to restore it:
FLASHBACK TABLE <your table name> TO BEFORE DROP;
If you get ORA-38305 you might have a tablespace issue - either run it as a different user or make sure it using a locally managed tablespace.
I have an oracle database shared by both an internal application and our website.
I know very little about oracle so will explain things how I understand it..
The database has two users APPUSER and WEBUSER when logged in (using Oracle SQL Developer) as APPUSER you can see all the tables in the database. When logged in as WEBUSER you cannot see anything but a couple of procedures, the APPUSER cannot see these procedures.
One procedure starts with:
create or replace PROCEDURE "UPDATE_DETAIL"
(v_ref IN APPUSER.DETAILS.REFERENCE%TYPE
,v_desc IN APPUSER.DETAILS.DESCRIPTION%TYPE
...
Line 2 has a red squiggly with "PLS-00201: identifier APPUSER is not declared"
I believe it has the "APPUSER.TABLE.COLUMN" because WEBUSER does not have direct access to the tables.
I have executed GRANT ALL ON UPDATE_DETAIL TO APPUSERlogged in as WEBUSER, but that did not fix the issue, WEBUSER is the owner of the procedure, but does not have anything listed in the Grants list (I assume because owner just has the rights be default?)
The Dependencies list for the procedure is also empty, but cannot find how to manually add one to it.
Not sure what else to try to fix this error.
Thanks.
If you want a procedure owned by WEBUSER (and I believe from your description that UPDATE_DETAIL is owned by WEBUSER) to reference objects owned by APPUSER, you would need to grant WEBUSER privileges on those objects. For example, as APPUSER
GRANT SELECT ON appuser.details
TO webuser;
This assumes that WEBUSER only needs to SELECT from the APPUSER.DETAILS table. If your procedure needs to INSERT, UPDATE, or DELETE data in that table, then WEBUSER would need to be granted additional privileges on the APPUSER.DETAILS table. You'd need to make similar grants for every table in APPUSER that the WEBUSER user needs to reference.
