I have read lots of post about how to update multiple columns but still can't find right answer.
I have one table and I would like update this table from another table.
Update table1
set (a,b,c,d,e,f,g,h,i,j,k)=(t2.a,t2.b,t2.c,t2.d,t2.e,t2.f,t2.g,t2.h,t2.i,t2.j,t2.k)
from
(
SELECT ..... with join ... where ....
) t2
where table1.id=table2.id
If I running only select statement (between brackets) then script return values but not working with update
TSQL does not support row-value constructor. Use this instead:
UPDATE table1
SET a = t2.a,
b = t2.b,
(...)
FROM
(
SELECT ..... with join ... WHERE ....
) t2
WHERE table1.id = table2.id
You don't need to use a sub-query you can also simply do the following....
Update t1
set t1.a = t2.a
,t1.b = t2.b
,t1.c = t2.c
,t1.d = t2.d
.......
from table1 t1
JOIN table2 t2 ON t1.id = t2.id
WHERE .......
