Use the ! and [ ] wildcard characters to create exclusion patterns

Create a customer list using specific characters as exclusion search patterns

Discussion:

Sometimes we need to exclude a set of characters to obtain the results we need.  For example, we might want to retrieve all our customers from the customers table except those whose names start with an A or B or C or D or E.  How about using the [!] wildcard to get the results we want? Note the returned recordset is sorted by last name and the first customer record to appear has a last name value starting with "F".  All the customers whose names start with a letter before that have been excluded from the recordset.    

Code:

SELECT *

FROM customers

WHERE ((lastname) Like "[!abcde]*")

ORDER BY lastname
 

Result:
