Query help

I need to update 6 column on 1 table depending on 2 other
columns on another table (All 8 columns exists on both
tables)
here is what I am trying to write and it gives me error:
Update Table1
Set start_date = (Select start_date from Table2),
end_date = (Select end_date from Table2),
user1 = (Select user1 from Table2),
user2 = (Select user2 from Table2),
user3 = (Select user3 from Table2),
user4 = (Select user4 from Table2)
FROM Table2
Where Table2.project = Table1.project AND
Table2.Pjt_entity = Table1.Pjt_entity
Thanks for any help.
Hi,
Try this,
Update Table1
Set a.start_date = b.start_date ,
a.end_date = b.end_date,
a.user1 = b.user1,
a.user2 = b.user2,
a.user3 = b.user3,
a.user4 = b.user4
FROM Table1 a,Table2 b
Where a.project = b.project
AND a..Pjt_entity = b.Pjt_entity

Well if you have a 1:1 between the tables, you just need to specify the
column to update:
Update Table1
Set start_date = b.start_date,
end_date = b.end_date,
etc...
FROM Table2 b
Where b.project = Table1.project AND
b.Pjt_entity = Table1.Pjt_entity

Left off a table in the FROM clause. See Hari's post instead.
