RE: Problem with Outer Join
Rick, That's not how I read it. He wants all dates returned showing whether an employee was present or not.

Hope this helps Tom Mercadante Oracle Certified Professional -Original Message- Sent: Thursday, August 22, 2002 8:38 AM To: Multiple recipients of list ORACLE-L Hi, In our employee's attendance application the attendance data is stored in table 'A' including employee ID and attendance date & time. Another table 'B' has one column with dates of current year (365 records). For the sake of simplicity, other fields are ignored. Table: A Employee_ID Attend_date (date with time) Table: B year_date (one record each for a day of current year i.e., 365 records) In a report (single employee at a time) showing all dates of the year and in front of it whether the employee was present or not we are running the following query. Assume that table A has 15 records of employee ID 123, the query should return 365 records with 15 records telling the time but it returns 15 records only. SELECT year_date, to_char(attend_date, 'hh:mi:ss' ) FROM A, B WHERE to_char(year_date, 'dd-mm-') = to_char(attend_date(+), 'dd-mm-') and employee_id = 123; To my understanding this is perhaps because of the filter employee_ID=123. What would be the query to get the required result? TIA!
