从SQL Server 2008中的表中检索数据

Question

I have 4 tables

1. table1 ( id, stateId(fk), name, carId(fk) )
2. table2 ( stateId(pk), state, countryId(fk) )
3. table3 ( countryId, country, currency )
4. table4 ( carId, car )

I want to retrieve name, state, country, car from the above tables through stored procedure using joins. And if some other easy way then please tell.

thanks.

Answer 1

A simple JOIN should do:

CREATE PROCEDURE schema.YourStoredProcedureName
AS
SELECT t1.name, t2.state, t3.country, t4.car
FROM table1 t1
    JOIN table2 t2 ON t1.stateId = t2.stateId
    JOIN table3 t3 ON t2.countryId = t3.countryId
    JOIN table4 t4 ON t1.carId = t4.carId
GO

Answer 2

No other easy method. Join is basic and easy ( http://msdn.microsoft.com/en-us/library/ms191517(v=sql.105).aspx )

select tbl1.name, tbl2.state, tbl3.country, tbl4.car
From table1 tbl1 
inner join table2 tbl2 on tbl1.stateid =tbl2.stateid   
inner join table3 tbl3 on tbl2.countryid = tbl3.countryid
inner join table4 tbl4 on tbl1.carId = tbl4.carId
