Since we cannot use MINUS query in MySQL, we will use LEFT JOIN to simulate the MINUS query. It can be understood with the help of the following example:ExampleIn this example, we are two tables namely Student_detail and Student_info having the following data −mysql> Select * from Student_detail; +-----------+---------+------------+------------+ | studentid | Name    | Address    | Subject    | +-----------+---------+------------+------------+ | 101       | YashPal | Amritsar   | History    | | 105       | Gaurav  | Chandigarh | Literature | | 130       | Ram     | Jhansi   ...

MySQL SUBSTRING_INDEX() function will return the same string as output if the argument ‘count’ has the value greater than the total number of occurrences of delimiter. It can be demonstrated with the following example −mysql> Select SUBSTRING_INDEX('www.google.co.in','.',4); +-------------------------------------------+ | SUBSTRING_INDEX('www.google.co.in','.',4) | +-------------------------------------------+ | www.google.co.in                          | +-------------------------------------------+ 1 row in set (0.00 sec)The above query returns the same string because 4 is greater than the total number of occurrences of delimiter provided as argument i.e. ‘.’.

For example, if a string contains four 2-bytes characters then OCTET_LENGTH() function will return 8. It is demonstrated in the example below −Examplemysql> Select OCTET_LENGTH('tutorialspoint'); +--------------------------------+ | OCTET_LENGTH('tutorialspoint') | +--------------------------------+ |                             14 | +--------------------------------+ 1 ...
