in my case when i used asp.net core app i had a mistake in my sql query. If your database contains many schemas, you have to write schema_name before table_name, like: Select * from SCHEMA_NAME.TABLE_NAME... i hope it will helpful.

You cannot directly access the table with the name customer. Either it should be user1.customer or create a synonym customer for user2 pointing to user1.customer. hope this helps..

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, 
           object_name 
    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?

I am using Oracle Database and i had same problem. Eventually i found ORACLE DB is converting all the metadata (table/sp/view/trigger) in upper case.

And i was trying how i wrote table name (myTempTable) in sql whereas it expect how it store table name in databsae (MYTEMPTABLE). Also same applicable on column name.

It is quite common problem with developer whoever used sql and now jumped into ORACLE DB.

Case sensitive Tables (table names created with double-quotes) can throw this same error as well. See this answer for more information.

Simply wrap the table in double quotes:

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

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;

Here is an answer: http://www.dba-oracle.com/concepts/synonyms.htm

An Oracle synonym basically allows you to create a pointer to an object that exists somewhere else. You need Oracle synonyms because when you are logged into Oracle, it looks for all objects you are querying in your schema (account). If they are not there, it will give you an error telling you that they do not exist.
