SQL

Dear Folks, I just wanted to ask regarding SQL statement, The question: Without using the logical operator OR, list all vendors from Ontario, Alberta, and BC who are not in the 416 and 780 area codes. Also, sort this list by city within the province:

The phone number is in the format (416)555-6453

I tried writing a statement in different ways.

SELECT * FROM vendors WHERE province IN ('ON','AB','BC') AND phonenumber NOT IN ('416' ,'780') ORDER BY province, city;
SELECT * FROM vendors WHERE province IN ('ON','AB','BC') AND (phonenumber NOT LIKE '416%') ORDER BY province, city;

// Tried using NOT BETWEEN 416 AND 780 AS well // Though 416 and 780 part is not working I need to exclude the vendors whose phone number starts with 416 or 780

Thanks in advance)))

Note that neither of these checks would match a number like the sample "(416)555-6453":

  • IN ('416', '780') :point_left: would only match those two 3-digit values
  • LIKE '416%' :point_left: would not match anything beginning with '('

SELECT *
FROM Vendors
WHERE Province IN ('ON', 'AB', 'BC') AND phonenumber NOT LIKE '(780)%' AND phonenumber NOT LIKE '(416)%'
ORDER BY province, city;

Thanks, Mr.Steven) This seems to work actually when I used the parentheses and WildCard character outside '(780)%'
