How can I do an UPDATE statement with JOIN in SQL Server?

Question

I need to update this table in SQL Server with data from its \'parent\' table, see below:

Table: sale

id (int)
udid         


        

Answer 1

PostgreSQL:

CREATE TABLE ud (id integer, assid integer);
CREATE TABLE sales (id integer, udid integer, assid integer);

UPDATE ud
SET assid = sales.assid
FROM sales
WHERE sales.id = ud.id;

Answer 2

And in MS ACCESS:

UPDATE ud 
INNER JOIN sale ON ud.id = sale.udid
SET ud.assid = sale.assid;

Answer 3

The following statement with FROM keyword is used to update multiple rows with a join

UPDATE users 
set users.DivisionId=divisions.DivisionId
from divisions join users on divisions.Name=users.Division

Answer 4

I was thinking the SQL-Server one in the top post would work for Sybase since they are both T-SQL but unfortunately not.

For Sybase I found the update needs to be on the table itself not the alias:

update ud
set u.assid = s.assid
from ud u
    inner join sale s on
        u.id = s.udid
