    Hmm…. I’m thinking that you really want to set the password for each user (I think), in which case you’ll need to have a join for the update, and that way you can eliminate your multiple values you are selecting.. because the way you have it, you’re updating all the values in the Goal table for pwd to the same value… the way below, you update each users pwd to be based on the row joined with the ID. Assuming you have one row for each usr in the esubmission table, this should work:

    
UPDATE Goal    
SET pwd = MD5(CONCAT(ID, LEFT(e.phone,3), '$='))                 
FROM Goal g, Esubmission e
where e.ID = g.usr
