Problem with Outer Join

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-yyyy') = to_char(attend_date(+),

To my understanding this is perhaps because of the filter employee_ID=123. What would be the query to get the required result?

TIA! Aleem
