You've missed the id out before the NOT; it needs to be specified.
SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'
You need to specify the column in both expressions.
SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'
After "AND" and after "OR" the QUERY has forgotten what it is all about.
I would also not know that it is about in any SQL / programming language.
if(SOMETHING equals "X" or SOMETHING equals "Y")
COLUMN NOT LIKE "A%" AND COLUMN NOT LIKE "B%"
