Hi,
I’m a java developer and a novice Postgres user. I’m trying to create a view that will display common fields from several different tables to simplify some JDBC queries.
To illustrate my question, consider this example -- I have the following three tables:
CARS
TRUCKS
SUVS
Although the tables contain numerous columns each, they each contain the following columns in common:
Manufacturer
Identification Number
Color
I would like to create a view that will display this common information as well as a column called “Type” that will indicate what kind of record it is – eg Car, Truck, or SUV.
I’m not trying to create a view that merges multiple rows into a single row in the view, but instead a view that will display a subset of each row from the different tables. For example, if each of the individual tables contains 100 rows, the view would contain 300 rows.
I have no problem creating a view that queries a single table, but I get stuck when trying to pull multiple tables into the view.
Can this type of view be created? If so, can someone point me in the right direction – a keyword or syntax example would be appreciated.
Thanks,
gcj
