'NOT LIKE' in an SQL query

Question

Why does this simple query return \'ORA-00936: missing expression\' (the database is Oracle as you can tell):

SELECT * FROM transactions WHERE id NOT LIKE \'1%\'         


        

Answer 1

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.
