It's me again - I have a new homework and I don't get any further.
The task is:
Find out the date of flight(DATE_FLY), flight number(FLY_NR), manufacturer(MANUF), type (TYP) and serial number (SER_NR) of all flights that fly from Frankfurt to Dallas between 10.11.2013 and 20.11.2013.
This is the departure_table:

I wrote the following query but it showed me "no data found":
select
dp.date_fly, dp.fly_nr, dp.manuf, dp.typ, dp.ser_nr
from
departure_table dp, fly_table fl
where
dp.fly_nr = fl.fly_nr
and start_fly = 'Frankfurt'
and dest_fly = 'Dallas'
and dp.date_fly between 10.11.2013 and 20.11.2013;
I've tried a simple join but I still only got the message "no data found":
select
dp.date_fly, dp.fly_nr, dp.manuf, dp.typ, dp.ser_nr
from
departure_table dp, fly_table fl
where
dp.fly_nr = fl.fly_nr;
I don't know what am I doing wrong... I would be very thankful if somebody could help to solve this problem with the join function.
I need to get this result:
DATE_FLY
FLY_NR
MANUF
TYP
SER_NR
18-NOV-13
LH-223
Airbus
A380
10010004
Thank you!
The column FLY_DATE has a VARCHAR2 format
This is bad practice. If you have a date then store it as a date. If you have to store it as a string (really, don't do that) then store it using ISO8601 formatting YYYY-MM-DD which can be sorted alphabetically into date-order (and not DD-MM-YYYY which cannot be easily sorted).
Since you have it in a (mostly unusable) string format, you need to convert it to a DATE using the TO_DATE function and compare it to DATE literals:
select dp.date_fly,
dp.fly_nr,
dp.manuf,
dp.typ,
dp.ser_nr
from departure_table dp
INNER JOIN fly_table fl
ON dp.fly_nr = fl.fly_nr
where start_fly = 'Frankfurt'
and dest_fly = 'Dallas'
and TO_DATE(dp.date_fly, 'DD.MM.YYYY') between DATE '2013-11-10' and DATE '2013-11-20';
Which, for the sample data:
CREATE TABLE departure_table (DATE_FLY, FLY_NR, MANUF, TYP, PER_NR, SER_NR, TIME_START) AS

I want last column 'Output' as stated in table. here the logic is :
for row 1 : sum of LBKUM & weekly_qty
for row 2 : sum of output of row 1 & weekly_qty of row 2
for row 3 : sum of output of row 2 & weekly_qty of row 3
for row 4 : sum of output of row 3 & weekly_qty of row 4
and so on.
Unlike other running total, I want LBKUM only once (in first row calculation) and in the next steps, output of previous row should be considered as shown in the description.
I hope this much would be sufficient.
Thanks in advance.

I have two tables from different databases, and I need to create a report, where there is need to see discrepancy in data:
Table A:
DATE
FLIGHT
AC
DEST
ATD
TDN
14.01.2022
150
AIRB
JFK
02:45
1:35
15.01.2022
152
BOEING
MIA
02:45
1:38
15.01.2022
145
AIRB
SEA
01:25
01:05
Table B:
DATE
FLIGHT
AC
DEST
ATD
TDN
14.01.2022
150
AIRB
JFK
02:45
1:35
15.01.2022
152
BOEING
MIA
02:39
1:38
15.01.2022
145
AIRB
SEA
01:28
01:15
The result should be only rows different in last two columns:
DATE
FLIGHT
AC
DEST
ATD_B
TDN_B
ATD_A
TDN_A
15.01.2022
152
BOEING
MIA
02:39
1:38
02:45
01:38
15.01.2022
145
AIRB
SEA
01:28
01:15
01:25
01:05
Now we can see where discrepancy is.
I have tried
select * from table_a
minus
select * from table_b
But it seems not the right approach
You can - for your sample data - JOIN both tables on the four identic columns and then set a condition that the combination of the two other columns must differ:
SELECT
a.a_date, a.flight, a.ac, a.dest,
b.atd AS atd_b, b.tdn AS tdn_b,
a.atd AS atd_a, a.tdn AS tdn_a
FROM
a JOIN b
ON
a.a_date = b.b_date
AND a.flight = b.flight
AND a.ac = b.ac
AND a.dest = b.dest
WHERE NOT (a.atd = b.atd AND a.tdn = b.tdn);
Sidenote: The condition in the WHERE clause can of course also be added in the join clause and the where clause can be removed.
But this will do only as long as the data is in the same form as your example.
Let's assume the are two further different entries in both table A and B for flight 145. Then I guess you would expect two rows for that flight, but in real life, it will be four.
You can replicate this behaviour here:
db<>fiddle
That's why people are asking you which rows should be put together. If you want to get two rows only for that case, you need to tell us how. If it's really intended to see all four rows, this query will work.
Just join the tables by columns and conditions from your Where clause mentioned in comments:
WITH
A (FLIGHT_DATE, FLIGHT, AC, DEST, ATD, TDN) AS
(
Select '14-JAN-22', 150, 'AIRB', 'JFK', '02:45', '1:35' From Dual Union All
Select '15-JAN-22', 152, 'BOEING', 'MIA', '02:45', '1:38' From Dual Union All
Select '15-JAN-22', 145, 'AIRB', 'SEA', '02:45', '1:05' From Dual
),
B (FLIGHT_DATE, FLIGHT, AC, DEST, ATD, TDN) AS
(
Select '14-JAN-22', 150, 'AIRB', 'JFK', '02:45', '1:35' From Dual Union All
Select '15-JAN-22', 152, 'BOEING', 'MIA', '02:39', '1:38' From Dual Union All
Select '15-JAN-22', 145, 'AIRB', 'SEA', '01:28', '1:05' From Dual
)

(A.FLIGHT_DATE = B.FLIGHT_DATE And A.FLIGHT = B.FLIGHT And A.AC = B.AC And A.DEST = B.DEST)

)

Does anyone have any idea how to do this?

If a decimal value is 0.40 I'd like to TO_CHAR(0.40) and get '0.40' back. Likewise, 50 should be to_char'd to '50'. As simple as what goes in, comes out, but as a CHAR, in all cases. So far I've tried the following:
select to_char(a, '99D90') test1,
to_char(a, '90D90') test2,
to_char(a, 'FM90D99') test3,
rtrim(to_char(a, 'FM90D99'), to_char(0, 'D')) test4
from (
select 50 a from dual
union all select 50.57 from dual
union all select 5.57 from dual
union all select 0.35 from dual
union all select 0.4 from dual
union all select 0.80 from dual
union all select .88 from dual
)
order by a;
returns:

.40 0.40 0.4 0.4

50.57 50.57 50.57 50.57
As you can see, what may work in one case doesn't in another. Do I have to test for whole numbers, decimal numbers, then leading and trailing zeros and apply a different formatter for each? Is there just a simple cast-like construct? (tried cast too btw, similar issues).
Solved
Oracle does not store or display formatting (even on non-persisted values as shown below). A Formatter must be applied for anything other than that.
0.4, .4 and 0.4000 are all the same. It is just the way you want to display the number.
As I understand, you want to preserve the rows as string, and not just display them. Then you could handle the conditions using a CASE expression.
TRUNC(NUMBER) truncates the decimal portion and gives you a whole number. This will be the driving condition.
So, when TRUNC(NUMBER) = 0, it means it has only decimal part, and we need to append a zero in the beginning, else just convert it into text.
For example,
SQL> WITH DATA AS(
2 select 50 a from dual
3 union all select 50.57 from dual
4 union all select 5.57 from dual
5 union all select 0.35 from dual
6 union all select 0.4 from dual
7 UNION ALL SELECT 0.80 FROM dual
8 UNION ALL SELECT .88 FROM dual
9 )
10 SELECT
11 CASE
12 WHEN TRUNC(A) = 0
13 THEN ltrim(to_char(a, '0D99'), ' ')
14 ELSE TO_CHAR(a)
15 END text
16 FROM DATA;
