Description

When you stumble upon an ORA-00942 error, the following error message will appear:

ORA-00942: table or view does not exist

Cause

You tried to execute a SQL declaration that references a desk or view that either does not exist, that you do now not have get entry to to, or that belongs to some other schema and you didn’t reference the desk by means of the schema name.

Resolution

The option(s) to resolve this Oracle error are:

Option #1

If this error occurred because the table or view does now not exist, you will need to create the table or view.

You can check to see if the desk exists in Oracle with the aid of executing the following SQL statement:

SELECT *
FROM all_objects
WHERE object_type IN ('TABLE','VIEW')
AND object_name = 'OBJECT_NAME';

For example, if you are looking for a suppliers table, you would execute:

SELECT *
FROM all_objects
WHERE object_type IN ('TABLE','VIEW')
AND object_name = 'SUPPLIERS';

Option #2

If this error befell due to the fact you do no longer have get admission to to the table or view, you will want to have the proprietor of the table/view, or a DBA furnish you the splendid privileges to this object.

Option #3

If this error happened due to the fact the table/view belongs to any other schema and you didn’t reference the desk via the schema name, you will want to rewrite your SQL to consist of the schema name.

For example, you can also have accomplished the following SQL statement:

SELECT *
FROM suppliers;

But the suppliers desk is no longer owned with the aid of you, but rather, it is owned through a schema called app, you could restoration your SQL as follows:

SELECT *
FROM app.suppliers;

If you do no longer understand what schema the suppliers table/view belongs to, you can execute the following SQL to locate out:

SELECT owner
FROM all_objects
WHERE object_type IN ('TABLE','VIEW')
AND object_name = 'SUPPLIERS';

This will return the schema name who owns the suppliers table.
