SQL 将列值作为枚举返回 - 来自另一列的 GetValue() 字段

Question

Here are the two tables;

Cathegories

----------------------------------------
Cathegory (tinyint)  |  Name (nvarchar)
----------------------------------------
0                    |  Field
1                    |  Mountain
2                    |  River
----------------------------------------

Places

------------------------------------------
Name (nvarchar)      |  Cathegory(tinyint)
------------------------------------------
Abc                  |  2
Xyz                  |  1
------------------------------------------

When I want to retrieve the Places listing Names and their Cathegories not in the int format but according to the description in Cathegories.

So retrieving Abc I want it like this;

"River" instead the '2'

Answer 1

Please use below query,

select c.name as place, p.name as name from Cathegories c
inner join Places p
on (c.Cathegory  = p.Cathegory);

Answer 2

You need to join two table on cathegory as shown below.

select
    p.name as places,
    c.name as category_name
from places p
join cathegories c
on p.cathegory = c.cathegory

Answer 3

Here is a version of multiple JOIN statements based on the accepted answer:

SELECT 

ColumnUserViews,

C.Cathegory AS VCathegory, 

ColumnUserPoints, 

T.Description AS VTag1,
TT.Description AS VTag2


FROM dbo.Users U

JOIN dbo.Cathegories C ON U.Cathegory = C.Cathegory
JOIN dbo.Tags T ON U.Tag1 = T.Tag
JOIN dbo.Tags TT ON U.Tag2 = TT.Tag

The keyword U defines physical table Users, T Tags, and TT also Tags (free to rename). VCathegory is a new virtual Column to be retrieved which holds the value of Users.Cathegory translated into Cathegories.Description ('s string equivalent) as per this current scheme.
