Home -> Community -> Mailing Lists -> Oracle-L -> 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.

Tom,
I think by the post he wants to limit result set by employee_id for ex. employee_id=123

Please respond
to ORACLE-L
Aleem,
Your query should be:
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,'dd-mm-yyyy') (+)
The above says to return all records from the year_date table and , oh, by the way, return any records in the employee table where dates match.
A better way to do this would be:
WHERE trunc(year_date) = trunc(attend_date) (+)
The Trunc command simply strips all time from date columns.
Hope this helps

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(+),
'dd-mm-yyyy') 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! Aleem
