How can I use SUBSTRING_INDEX() function to get the substring as output which is between two same delimiters in a string?

We need to use nested SUBSTRING_INDEX() function for getting the substring as output which is between two same delimiters in a string. For example, from the string ‘www.tutorialspoint.com’, we want the substring ‘tutorialspoint’, which is in between two same delimiters ‘.’ as output then SUBSTRING_INDEX() function can be used in nested form as follows −

mysql> Select SUBSTRING_INDEX(SUBSTRING_INDEX('www.tutorialspoint.com','.',2),'.',-1)AS 'Nested SUBSTRING_INDEX';
+------------------------+
| Nested SUBSTRING_INDEX |
+------------------------+
| tutorialspoint         |
+------------------------+
