ORA-00942: Table or View Does Not Exist – Complete Solution Guide

The ORA-00942: table or view does not exist error is one of the most common Oracle Database errors. It occurs when Oracle cannot locate the specified table or view, or when the user does not have sufficient privileges to access it.

This guide will help you identify the root cause and fix ORA-00942 quickly using step-by-step solutions and real-world examples.

What is ORA-00942 Error?

The ORA-00942 error occurs when:

• The table or view does not exist in the database
• The object exists but is in a different schema
• You don’t have permission to access it

Error Message

ORA-00942: table or view does not exist

Quick Fix (Fast Solution)

If you're in a hurry, follow these steps:

1. Verify the table name spelling
2. Check the schema name
3. Confirm the table exists
4. Ensure proper privileges are granted

Common Causes of ORA-00942

• Table Not Created – The table doesn’t exist
• Wrong Schema – Table exists but under another user
• Missing Privileges – No SELECT/INSERT rights
• Synonym Issues – Broken or missing synonyms
• Case Sensitivity – Quoted identifiers mismatch
• Object Dropped – Table was deleted

Step-by-Step Solutions

1. Check if Table Exists

 SELECT table_name FROM all_tables WHERE table_name = 'EMPLOYEES'; 

If no rows are returned, the table does not exist.

2. Check the Correct Schema

Tables may exist in another schema:

 SELECT owner, table_name FROM all_tables WHERE table_name = 'EMPLOYEES'; 

Then query using:

 SELECT * FROM HR.EMPLOYEES; 

3. Verify User Privileges

 SELECT * FROM all_tab_privs WHERE table_name = 'EMPLOYEES'; 

If no access exists, request permissions:

 GRANT SELECT ON HR.EMPLOYEES TO your_user; 

4. Check Synonyms

Sometimes applications use synonyms:

 SELECT * FROM all_synonyms WHERE synonym_name = 'EMPLOYEES'; 

If missing, create one:

 CREATE SYNONYM employees FOR HR.employees; 

5. Handle Case Sensitivity

If a table was created using quotes:

 CREATE TABLE "Employees" (...); 

You must query it exactly:

 SELECT * FROM "Employees"; 

6. Check Recently Dropped Objects

 SELECT * FROM recyclebin WHERE original_name = 'EMPLOYEES'; 

Restore if needed:

 FLASHBACK TABLE employees TO BEFORE DROP; 

Special Case: ORA-00942 in Stored Procedures

This error often appears in PL/SQL procedures due to missing privileges.

Important: Roles are not active inside stored procedures.

Solution:

 GRANT SELECT ON HR.EMPLOYEES TO your_user; 

Use direct grants instead of roles.

Real-World Scenario

A developer executed a query successfully in SQL Developer but got ORA-00942 inside a stored procedure.

Cause: Privileges were granted via a role.

Fix: Granted direct SELECT permission.

Result: Issue resolved immediately.

Best Practices to Avoid ORA-00942

• Always use schema-qualified names
• Grant privileges directly (not via roles)
• Avoid quoted identifiers
• Maintain proper naming conventions
• Validate objects before deployment
• Use synonyms carefully

Frequently Asked Questions (FAQ)

Why does ORA-00942 occur even when table exists?

Most likely due to missing privileges or wrong schema.

How do I fix ORA-00942 in PL/SQL?

Grant direct permissions instead of using roles.

Can synonyms cause ORA-00942?

Yes, if they are invalid or missing.
