How to Solve ORA-00942 table or view does not exist

ORA-00942 is one of the many errors which Oracle developer ,DBA often gets.

Lets first look at the OERR output


Cause: The table or view entered does not exist, a synonym that is not allowed here was used, or a view was referenced where a table is required.

Existing user tables and views can be listed by querying the data dictionary. Certain privileges may be required to access the table. If an application returned this message, the table the application tried to access does not exist in the database, or the application does not have access to it.

Action: Check each of the following:

  • the spelling of the table or view name.
  • that a view is not specified where a table is required.
  • that an existing table or view name exists.
  • Contact the database administrator if the table needs to be created or
    if user or application privileges are required to access the table.
