I have 2 tables. One of the tables have 7 values and the other table has 5 values. These tables have their primary keys in common. I want to join both tables this way:
If I have a Table
English French
-------------------- --------------------
one Un
two Deux
three Trois
four Quatre
four Quattro
five Cinq
five Cinco
And another one:
English French
-------------------- --------------------
one aaaaa
two bbbbb
three ccccc
four
five
I want to have a table like this:
English French
-------------------- --------------------
one Un
one aaaaa
two Deux
two bbbb
three Trois
three ccccc
four Quatre
four Quattro
four --------
five Cinq
five Cinco
five ----------
I tried using join but it does a linear combination of the values four and five. How can I go about doing this? Thanks.

Apart from the column name, where i put date_restitution contains real dates.
You could use a UNION:
select English, French from Table1
UNION ALL
select English, French from Table2
or a full outer join
select distinct coalesce(T1.English, T2.English), coalesce(T1.French, T2.French)
from Table1 T1
full outer join Table2 T2 on T1.English = T2.English
EDIT:
Assuming you want restitutions.date_restitution to appear in place of date_location for restitution records -
SELECT l.num_client, l.date_location, l.duree, to_number(null) km_restitution, to_number(null) km_parcouru
FROM locations l
UNION ALL
SELECT r.num_client, r.date_restitution date_location, 0 duree, r.km_restitution, r.km_parcouru
FROM restitutions r
FURTHER EDIT (based on supplied results):
select l.id_agence,
l.num_immatricul,
l.num_client,
l.duree,
l.date_location,
decode(r.date_restitution, NULL,'----------------', 'date_restitution')
as date_restitution -- or just r.date_restitution
from location l
left outer join restitution r
on l.id_agence = r.id_agence and
l.num_immatricul = r.num_immatricul and
l.num_client = r.num_client and
l.date_location <= r.date_restitution
You actually need a union:
SELECT English, French FROM T1
UNION
SELECT English, French FROM T2
If you don't care about duplicates, you can use UNION ALL
Edit after OP's comment:
SELECT l.num_client, l.id_agence, l.num_immatricul
FROM locations l
UNION
SELECT r.num_client, r.id_agence, r.num_immatriculation
FROM restitutions r
The following should do it.
SELECT tab1.English, tab1.French
UNION
SELECT tab2.English, tab2.French
For other readers who might have the same problem. From the experience I had with this problem, it would be a good idea to join tables locations and restitutions since both of them have almost the same attributes and data. I finally decided in changing my database and creating a new table that contains both the attributes of location and restitution and setting some not availabe values to NULL. This would reduce a lot of joins between tables and queries would be easier to handle.

1005 7 2005 6 3005 8
How do i specify that in a sql query? Any suggestions? I tried UNION but giving some errors.
Normally, you would have a column which would separate out EID from series, leaving you with just values like 001, 002, etc.
In this case you could JOIN the data on itself +1000 times the series number. Something like this:
SELECT
t1.EID, t1.PCNum,
t2.EID, t2.PCNum,
t3.EID, t3.PCNum
FROM
table_name t1
INNER JOIN table_name t2 on t1.EID+1000 = t2.EID
INNER JOIN table_name t3 on t1.EID+2000 = t3.EID
WHERE t1.EID BETWEEN 1000 AND 1999
ORDER BY t1.EID

plz help me for solving this.
group by c.name, c.salary with sum(salary) is what you want:
select c.name, c.salary, sum(o.amount )
from CUSTOMERS c
inner join ord o on c.id=o.customer_id
group by c.name, c.salary;
try this if it will work.
select c.name,c.salary,sum(o.amount)
from CUSTOMERS c
inner join ord o
on c.id=o.customer_id
group by 1,2;
Thanks.
select c.name,c.salary,SUM(o.amount )
from CUSTOMERS c
inner join ord o
on c.id=o.customer_id
GROUP BY c.name,c.salary
I think this will work
Use Left Join or RIGHT JOIN
select c.name,c.salary,o.amount
from CUSTOMERS c
left join ord o
on c.id=o.customer_id;

Question:
How do I sum up the price fields, SOME PRICES ARE NOT AVAILABLE because a reservation was either made for accommodation only or flight only, hence both values will not be present always and this is where the issue lies
DEPART_FLIGHT_PRICE RETURN_FLIGHT_PRICE ACCOMMODATION_PRICE
Furthermore:
I wish to insert or update the SUM of those three values into a SUBTOTAL in the reservation table, perhaps by using select into or update, I have spent a whole day trying to do this but my skills are limited. any help will be greatly appreciated.

UPDATE HOLIDAY_RESERVATION R SET SUBTOTAL =

Subsequently the code was added to a trigger (which was the original intention)
CREATE OR REPLACE TRIGGER HR_SUBTOTAL
BEFORE INSERT OR UPDATE ON HOLIDAY_RESERVATION
FOR EACH ROW
BEGIN
SELECT
NVL((SELECT F.Fli_Price FROM Flight F WHERE F.Fli_ID = :new.In_Flight_ID), 0) +
NVL((SELECT F.Fli_Price FROM Flight F WHERE F.Fli_ID = :new.Out_Flight_ID), 0) +
NVL((SELECT AC.Acc_PricePn FROM Accomodation AC WHERE AC.Acc_ID = :new.Acc_ID), 0)
INTO :new.Subtotal
FROM dual;
END;
/
For the SUM, assuming you want to treat NULL values as 0, you'd just need to do an NVL on the numbers
NVL( DEPART_FLIGHT_PRICE, 0 ) +
NVL( RETURN_FLIGHT_PRICE, 0 ) +
NVL( ACCOMMODATION_PRICE, 0 )
As for the UPDATE, it sounds like you just need a correlated UPDATE statement.
UPDATE reservation r
SET subtotal = (SELECT (SELECT NVL( DEPART_FLIGHT_PRICE, 0 ) +
NVL( RETURN_FLIGHT_PRICE, 0 ) +
NVL( ACCOMMODATION_PRICE, 0 )
FROM (SELECT RESV_ID,
BOOKING_CUS_ID,
ACC_ID,
(SELECT F.FLI_PRICE
FROM FLIGHT F
WHERE F.FLI_ID = R.IN_FLIGHT_ID) AS DEPART_FLIGHT_PRICE,
(SELECT F1.FLI_PRICE
FROM FLIGHT F1
WHERE F1.FLI_ID = R.OUT_FLIGHT_ID) AS RETURN_FLIGHT_PRICE,
(SELECT AC.ACC_PRICEPN
FROM ACCOMMODATION AC
WHERE AC.ACC_ID = R.ACC_ID) AS ACCOMMODATION_PRICE
FROM dual));
You are asking:
How do I sum up the price fields, as you can see some of them can have nulls.
DEPART_FLIGHT_PRICE RETURN_FLIGHT_PRICE ACCOMMODATION_PRICE
Just enclose them in NVL function as follows:
NVL(DEPART_FLIGHT_PRICE, 0)
and then sum them up.
For the second part, what you need is a MERGE statement. A good example is at http://www.oracle-developer.net/display.php?id=203
