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
