mysql: find rows which have a field that is a substring of “string”

Question

is there a way to write an sql query that finds all rows where the field value is a substring of a given string.

Example:

table names

Name      |      N         


        

Answer 1

You can also reverse the LIKE condition.

select * from names where "who is rohit" LIKE  CONCAT('%', Name, '%');

Note, this probably isn't any faster than instr("who is Rohit", Name) but it may be.
