I have 2 tables and I need to make one view of them like if it was 1 single table
Table1 DEVICE
+-----+-------+-----------+
|DevID|DevName|DevIP |
+-----+-------+-----------+
|1 |HH1 |192.168.1.1|
+-----+-------+-----------+
|2 |HH2 |192.168.1.2|
+-----+-------+-----------+
Table2 DEVICECUSTOMDATA
+-----+------------+--------+
|DevID|Name |Value |
+-----+------------+--------+
|1 |Model |CN70 |
+-----+------------+--------+
|1 |BuildVersion|1.2 |
+-----+------------+--------+
|1 |BuildDate |20140113|
+-----+------------+--------+
|2 |Model |MC55 |
+-----+------------+--------+
|2 |BuildVersion|1.2 |
+-----+------------+--------+
|2 |BuildDate |20140110|
+-----+------------+--------+
The resulting table should be:
+-----+-------+-----------+-----+------------+---------+
|DevID|DevName|DevIP |Model|BuildVersion|BuildDate|
+-----+-------+-----------+-----+------------+---------+
|1 |HH1 |192.168.1.1|CN70 |1.2 |20140113 |
+-----+-------+-----------+-----+------------+---------+
|2 |HH2 |192.168.1.2|MC55 |1.2 |20140110 |
+-----+-------+-----------+-----+------------+---------+
I would appreciate any help to do this. Thanks

Answer 1

SQL SERVER:
See SqlFiddle:
SELECT d.DevId, d.DevName, d.DevIp, p.Model, p.BuildVersion, p.BuildDate
FROM DEVICE d
JOIN (
SELECT *
FROM DEVICECUSTOMDATA
PIVOT (MAX(Value) FOR Name IN ([Model], [BuildVersion], [BuildDate])) as Something) p
on d.DevId = p.DevId

Working Online Example (SQL Server Syntax): SQL Fiddle
Result:
SQL Script:
DECLARE #Device TABLE (
DevID int not null,
DevName varchar(max) not null,
DevIP varchar(max) not null
)
insert into #Device values ('1', 'HH1','192.168.1.1')
insert into #Device values ('2', 'HH2','192.168.1.2')
DECLARE #DeviceCustomData TABLE (
CDevID int not null,
Name varchar(max) not null,
Value varchar(max) not null
)
insert into #DeviceCustomData
values ('1','Model','CN70')
insert into #DeviceCustomData
values ('1','BuildVersion','1.2')
insert into #DeviceCustomData
values ('1','BuildDate','20140113')
insert into #DeviceCustomData
values ('2','Model','MC55')
insert into #DeviceCustomData
values ('2','BuildVersion','1.2')
insert into #DeviceCustomData
values ('2','BuildDate','20140110')
SELECT *
FROM
(SELECT d.DevID, d.DevName, d.DevIP, c.Value, c.Name
FROM #Device d
inner join #DeviceCustomData c on d.DevID = c.CDevID) AS SourceTable
PIVOT(
MIN(Value)
FOR Name in ([Model],[BuildVersion],[BuildDate])
) as PivotTable
