Question

ORA-00998 error while changing a view def

Asked by: TheoViset

I have a view that calls a function with an incorrect dateformat, and I need to change that format as parameter for the function, but when I save I get ORA-00998 error:

Viewname: ILN_DUAL

SELECT
(to_char(sysdate, 'J') -
to_char(to_date('01-01-1970', 'DD-MM-YYYY'), 'J')) * 86400 +
to_char(sysdate, 'HH24') * 3600 +
to_char(sysdate, 'MI') * 60 -      
is_dlst(to_char(sysdate, 'YYYY-MM-DD')) * 3600
FROM DUAL

and when I change the last date format to 'DD-MM-YY' and save this:

ORA-00998 Must name this expression with a column name.

Cause: An expression or function was used in a CREATE VIEW statement, but no corresponding column name was specified. When expressions or functions are used in a view, all column names for the view must be explicitly specified in the CREATE VIEW statement.

Action: Enter a column name for each column in the view in parentheses after the view name.


But, I do not use columnnames in this view. Where do I have to put what column name??? The ILN_DUAL view is used to calculate a scalar date/time from a date, and is_dlst is used to determine daylight savings time. It returns 1 or 2 which reflect the hours to subtract in or out of DST.

Anyone any suggestions?

Try this:

SELECT
