Question

I have a statement like this:

select lastname,firstname,email,floorid 
from employee 
where locationid=1 
    and (statusid=1 or statusid=3) 
order by floorid,lastname,firstname,email

The problem is the column floorid. The result of this query is showing the id of the floors.

There is this table called floor (has like 30 rows), which has columns id and floornumber. The floorid (in above statement) values match the id of the table floor.

I want the above query to switch the floorid values into the associated values of the floornumber column in the floor table.

Can anyone show me how to do this please?
I am using Microsoft sql server 2008 r2.

I am new to sql and I need a clear and understandable method if possible.

Answer 1

You have to do a simple join where you check, if the floorid matches the id of your floor table. Then you use the floornumber of the table floor.

select a.lastname,a.firstname,a.email,b.floornumber 
from employee a
join floor b on a.floorid = b.id
where a.locationid=1 and (a.statusid=1 or a.statusid=3) 
order by a.floorid,a.lastname,a.firstname,a.email
