Question

We have a table with several fields, like 300+. the structure is like this:
storenum, Monval1, Monval2… Monval45, Monval46… Tuesval1, Tuesval2 and so on. basically for values 1 thru 53 there is a version for each day of the week so 53 fields * 7 days plus a few other random fields.

i need to update stores 3 thru 285 with data from store 1. what i tried:

Update (Select MonVal1... SunVal53 from table1 
 where storenum in (3, 4,...284,285)) as Dest
From (Select MonVal1... SunVal53 from table1 
 where storenum =1) as Source

but its a nogo.

can what i’m trying to do even be done?

Answer 1

Update table1 set
    MonVal1    = origin.MonVal1, 
    /* the orher fields here */
    SunVal53   = origin.SunVal53
from table1
inner join table1 as origin on origin.storenum = 1
where table1.storenum in (3, 4,...284,285)
