Question: on ORA-00933: SQL command not properly ended

ORA-00933: SQL command not properly ended

Cause: The SQL statement ends with an inappropriate clause. For example, an ORDER BY clause may have been included in a CREATE VIEW or INSERT statement. ORDER BY cannot be used to create an ordered view or to insert in a certain order.

Action: Correct the syntax by removing the inappropriate clauses. It may be possible to duplicate the removed clause with another SQL statement. For example, to order the rows of a view, do so when querying the view and not when creating it. This error can also occur in SQL*Forms applications if a continuation line is indented. Check for indented lines and delete these spaces.

Answer by Chenn:  I am never able to run an update using a join. You need a subselect. Filter it by pushing your field from the main query into the subselect. I'm not sure what your NI.No field is so you may need to take a look at that...

UPDATE PEOPLE a
SET a.SURNAME = (
select b.SURNAME
from PEOPLE b
where b.NI.NO = a.NI_NUMBER
)
