4 solutions available

Check if the table exists in the schema

1

Search for the table in your schema

SELECT table_name
FROM user_tables
WHERE table_name = 'EMPLOYEES';

2

Search all schemas you have access to

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

Specify the schema owner if table is in different schema

1

Query with schema prefix

-- Instead of:
SELECT * FROM employees;

-- Use full path:
SELECT * FROM hr.employees;

2

Or create a synonym

CREATE SYNONYM employees FOR hr.employees;

-- Now you can use:
SELECT * FROM employees;

You may not have SELECT privilege on the table

1

Check your privileges on the table

SELECT privilege
FROM user_tab_privs
WHERE table_name = 'EMPLOYEES';

2

Request access from DBA

-- DBA runs:
GRANT SELECT ON hr.employees TO your_user;

Synonym might point to non-existent or inaccessible table

1

Check if object is a synonym

SELECT synonym_name, table_owner, table_name
FROM user_synonyms
WHERE synonym_name = 'EMPLOYEES';

2

Verify the target table exists

-- Check if synonym target exists
SELECT owner, object_name, object_type
FROM all_objects
WHERE object_name = 'EMPLOYEES';

❓

Make sure you committed the transaction. Also check if you created it in a different schema.

Query ALL_TABLES view: SELECT owner, table_name FROM all_tables;
