Re: join two tables with sharing some columns between two - Mailing list pgsql-sql

If I understand correctly... I think this should work:

SELECT    table1.id,    table1.person_name,    table2.car_description,    table1.date_arrival,    table1.date_departure
FROM    table1, table2
WHERE    table1.id = table2.id
;

Assuming the date_arrival and date_departure fields are the same on both
tables then it doesn't matter if you pull them from table1 or table2,
otherwise you'll need to change the SELECT appropriately.

If you want it to go in to a new table as well as opposed to just a query,
you could have a play with SELECT INTO...

Cheers,

Subject: [SQL] join two tables with sharing some columns between two

Hi,

I have two tables like these: (this is an example, the actual tables
have diffferent fields and meanings)

TABLE1
id
person_name
date_arrival
date_departure

TABLE2
id
car_description
date_arrival
date_departure

I'd like to make a query to have such resulting table

RESULTING_TABLE
id
person_name
car_description
date_arrival
date_departure

the id is the primary key for the three tables and it's unique for the
three (id in table1 cannot be in table2, I use the same counter to
generate the id for table1 and table2).


I is possible to create such a query?

Thanks
