MSSQL Regular expression

Disclaimer: The original question was about MySQL. The SQL Server answer is below.

MySQL

In MySQL, the regex syntax is the following:

SELECT * FROM YourTable WHERE (`url` NOT REGEXP '^[-A-Za-z0-9/.]+$')

Use the REGEXP clause instead of LIKE. The latter is for pattern matching using % and _ wildcards.

SQL Server

Since you made a typo, and you're using SQL Server (not MySQL), you'll have to create a user-defined CLR function to expose regex functionality.

Take a look at this article for more details.

This is what I have used in the end:

SELECT *, 
  CASE WHEN [url] NOT LIKE '%[^-A-Za-z0-9/.+$]%' 
    THEN 'Valid' 
    ELSE 'No valid' 
  END [Validate]
FROM 
  *table*
  ORDER BY [Validate]
