SQL Error: ORA-00942 table or view does not exist


I use SQL developer and i made a connection to my database with the system user, after I created a user and made a another connection with that user with all needed privileges.

But when I try to proceed following I get the SQL Error

ORA-00942 table or view does not exist.:

INSERT INTO customer (c_id,name,surname) VALUES ('1','Micheal','Jackson')

The Best Answer is


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.

To reproduce the problem, execute the following SQL as user1:

create sequence seq_customer_id;

create table customer (
c_id number(10) default seq_customer_id.nextval primary key,
name varchar(100) not null,
surname varchar(100) not null

grant select, insert, update, delete on customer to user2;

Then, execute this insert statement as user2:

insert into user1.customer (name,surname) values ('michael','jackson');

The result will be "ORA-00942: table or view does not exist" even though user2 does have insert and select privileges on user1.customer table and is correctly prefixing the table with the schema owner name. To avoid the problem, you must grant select privilege on the sequence:

grant select on seq_customer_id to user2;

Either the user doesn't have privileges needed to see the table, the table doesn't exist or you are running the query in the wrong schema

Does the table exist?

    select owner, 
    from dba_objects 
    where object_name = any ('CUSTOMER','customer');

What privileges did you grant?

    grant select, insert on customer to user;

Are you running the query against the owner from the first query?
