Transpose and join one column SQL - sql

Question

I have a table which will be filled in the following manner:
ID
MODELID
PROPERTYID
V
Q
T
TYPE
1
LotNumber
NULL
1243582
NULL
2021-10-08 00:00:00.000
NULL
2
GoodStrips
NULL
39288
NULL
2021-10-08 00:00:00.000
NULL
3
StripProc
NULL
492
NULL
2021-10-08 00:00:00.000
NULL
4
StripRaw
NULL
883
NULL
2021-10-08 00:00:00.000
NULL
5
LabelProc
NULL
414
NULL
2021-10-08 00:00:00.000
NULL
6
LabelRaw
NULL
54
NULL
2021-10-08 00:00:00.000
NULL
7
SmallTips
NULL
101
NULL
2021-10-08 00:00:00.000
NULL
8
LongTips
NULL
65
NULL
2021-10-08 00:00:00.000
NULL
For each block of 8 rows, the timestamp will be identical.
Ideally, I'd like to make another table or view from this initial table where my lot number or timestamp would act as an ID column, and all the other values would be placed in the same row, like so:
LotNumber
GoodStrips
StripProc
StripRaw
LabelProc
LabelRaw
SmallTips
LongTips
T
1243582
39288
492
883
414
54
101
65
2021-10-08 00:00:00.000
I've been trying to get an inner join working to no avail.
My attempt at doing the first few as a test:
Select m1.T, m1.MODELID, m2.V, m3.V
from Rejects945 m1
inner join Rejects945 m2 on m2.T = m1.T
inner join Rejects945 m3 on m3.T = m1.T
where m2.V = 'GoodStrips'
where m3.V = 'StripProc'
where MODELID = 'LotNumber'
I get the following error:
Msg 156, Level 15, State 1, Line 6
Incorrect syntax near the keyword 'where'
Any help is greatly appreciated.

You can do this with the PIVOT function.
PIVOT & UNPIVOT
See sample code below:
CREATE TABLE #Test
(
ID INT
,MODELID VARCHAR(100)
,V INT
,T DATETIME
)
INSERT #Test (ID, MODELID, V, T)
VALUES (1,'LotNumber',1243582,'8/10/2021 12:00:00 AM')
,(2,'GoodStrips',39288,'8/10/2021 12:00:00 AM')
,(3,'StripProc',492,'8/10/2021 12:00:00 AM')
,(4,'StripRaw',883,'8/10/2021 12:00:00 AM')
,(5,'LabelProc',414,'8/10/2021 12:00:00 AM')
,(6,'LabelRaw',54,'8/10/2021 12:00:00 AM')
,(7,'SmallTips',101,'8/10/2021 12:00:00 AM')
,(8,'LongTips',65,'8/10/2021 12:00:00 AM')
,(9,'LotNumber',2345234,'9/10/2021 12:00:00 AM')
,(10,'GoodStrips',4543,'9/10/2021 12:00:00 AM')
,(11,'StripProc',455,'9/10/2021 12:00:00 AM')
,(12,'StripRaw',43,'9/10/2021 12:00:00 AM')
,(13,'LabelProc',24,'9/10/2021 12:00:00 AM')
,(14,'LabelRaw',5,'9/10/2021 12:00:00 AM')
