How to approach solving a SQL problem?

1. SQL Question #3 When I run this code (table OPJEUL.MCD_COSTS_9C_ACCTS_05 does not exist) CREATE TABLE OPJEUL.MCD_COSTS_9C_ACCTS_05 AS SELECT * FROM OPJEUL.COSTS_9C_ACCTS_05 I get an Ora-01847, day must be between 1 and end of the month. There are 2 dates in the input view and all are valid. I wrote a PL/SQL proc to kick out any invalid dates and none were rejected. Also, looking at the dates, none of them seem wrong. If I create an empty table and do an Insert, the same error occurs. However, if I change from a table to a view CREATE or replace view OPJEUL.COSTS_9C_ACCTS_05_V AS SELECT * FROM OPJEUL.COSTS_9C_ACCTS_05 the view is created without any problems.
