Thanks in Advance to All

My Query is that I want to find date working date before or after OFF or AL Day

for e.g 17-OCT-21 is SUNDAY and 23-OCT-2021 is SATURDAY and both Stat is OFF so I want Date 16-OCT-21 and 22-OCT-2021 and after OFF day or AL Absent 25-OCT-21 i want date 26-OCT-2021

I had tried this query but didn't get single date

1 Select emp_code,att_Date,stat,to_char(att_Date, 'fmday'),
2 case
3 when to_char(att_Date, 'fmday') = 'friday' then
4 att_Date+ 3
5 when to_char(att_Date, 'fmday') = 'saturday' then
6 att_Date + 2
7 else
8 att_Date + 1
9 end next_day
10* from attend

SQL> /

MP_CO ATT_DATE STAT TO_CHAR(A NEXT_DAY
----- --------- ---- --------- ---------
60213 15-OCT-21 P friday 18-OCT-21
60213 16-OCT-21 P saturday 18-OCT-21

Please format your post as explained in How to use [code] tags and make your code easier to read, and align the column in result.

You have been asked, more than once, to follow the Forum rules: Format your posts correctly using [code] tags for code, and use type casting functions such as TO_DATE when working with dates and strings.

It us extremely rude of you to ignore these requests.

Your answer:

sorry for that

You are so sorry that you ignore it in your next topic.

And post a test case, test it before but do NOT post the execution, just the statements, we can't copy and paste an execution.


In the end:

You are trying to insert a character string ('01-JAN-2021') into a column that is defined as a DATE datatype. This will force an implied TO_DATE operation to convert that string into the internal, binary structure of a DATE. This may or may not succeed, depending on the controlling setting of NLS_DATE_FORMAT. Better to leave nothing to chance and explcitly use TO_DATE:

insert into TBAL values('121028',TO_DATE('01-JAN-2021',DD-MON-YYYY'),'01',2021);

keepling TIME_IN and TIME_OUT is a very serious design flaw. These should be DATE types. DATE is somewhat mis-named, as it is actually a date and time, down to the second. And with that, you don't need a separate column for ATT_DATE.

CREATE TABLE ATTEND
(
EMP_CODE VARCHAR2(6) NOT NULL,
TIME_IN DATE,
TIME_OUT DATE,
STAT VARCHAR2(4))
;

Insert into ATTEND
(EMP_CODE,
TIME_IN,
TIME_OUT,
STAT)
Values
('160213',
TO_DATE('10/15/2021 09:02:00', 'MM/DD/YYYY HH24:MI:SS'),
TO_DATE('10/15/2021 17:15:00' 'MM/DD/YYYY HH24:MI:SS'),
'P'
)
;

So shahzad-ul-hasan = glmjoy which wouldn't surprise me as their behaviors are the same one.
