Question

I am currently working on a project where I have several string that may start with different message but somewhere in the string will contain a :.

For example the field may include

Unknown username/password attempted to login. User: admin Failed to

add user account. MySQL Error: certain my sql error Unknown

username/password attempted to login. User: administrator

Basically I want to group the fields together up to the : sign e.g. Unknown username/password attempted to login. User: would be grouped as 1 entry.

Thanks for any help you can provide.

SELECT msg1,wholemsg FROM 
 (SELECT SUBSTRING_INDEX(message, ':', 1) AS msg1, message as wholemsg FROM <your table>
  WHERE <your condition>)
GROUP BY msg1
