Is there a quick way to write update sql statement to add a number ZERO in front of account numbers. I was able to update single account, but i don't know how to write statement to update all in once..

UPDATE TABLE1
SET ACCTNO='043697644'
FROM TABLE1
WHERE ACCTNO='43697644'

But I have 200 accounts that need to add leading 0 in front of these accounts). Please advise! thanks,

VARCHAR(11)

I wonder if we can write case or if statement to update...if acctno <10 then add zero in front?

thanks

UPDATE TABLE1
SET ACCTNO='0' + ACCTNO
WHERE LEN(ACCTNO)<10
