I am trying to make a login form through Oracle’s Form Builder, I have a table called TRAVEL_USER which I made in SQLPlus.

I have made a button and am using the trigger WHEN-BUTTON-PRESSED.

To start myself off I am using this code to simply count the number of users registered on the system:

DECLARE
    TUsers NUMBER := 0;
BEGIN
    SELECT COUNT(*) FROM TRAVEL_USER;
END;

When compiling this I get the following error:
Error 201: identifier ‘TRAVEL_USER’ must be declared.

I can confirm that this table exists in the database I am connecting to, I checked via SQLPlus and the data block wizard in the Oracle Forms Builder.

I connect to the database with full admin privileges (using the system username).

    What user owns the TRAVEL_USER table? If you’re connecting as the user SYSTEM (Bad Idea) then you likely need to fully qualify the table name with the schema name that owns the table:

    SELECT COUNT(*) FROM owner.travel_user;

    Either that or create a public synonym for the table:

    CREATE PUBLIC SYNONYM travel_user FOR owner.travel_user;

    You should not make a habit of using the SYS or SYSTEM accounts for application purposes. They are system accounts and should be used for system purposes.
