1.Execute this function in mysql. 2.this will create a function. Now you can use this function anywhere you want.

 SELECT `getNameInitials`('Kaleem Ul Hassan', ' ') AS `NameInitials`;

3. The above getNameInitails first parameter is string you want to filter and second is the spectator character on which you want to separate you string. 4. In above example 'Kaleem Ul Hassan' is name and i want to get initials and my separator is space ' '.
