Update multiple columns in SQL

Question

Is there a way to update multiple columns in SQL server the same way an insert statement is used?

Something like:

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 table2 t2

where table1.id=table2.id

Or something like that, rather than like so:

update table set a=t2.a,b=t2.b etc 

which can be pretty tiresome to write if you have 100+ columns.

Answer 1

Try using below code:

UPDATE table1 

SET a = t2.a, b = t2.b, .......

FROM table2 t2

WHERE table1.id = t2.id

Note: The above code will work in most SQL dialects, excluding Oracle.
