mysql findinset

The FIND_IN_SET function in MySQL is used to find the position of a string within a comma-separated list of strings. The syntax for using FIND_IN_SET is as follows:

FIND_IN_SET(search_string, comma_separated_list)

Here, search_string is the string that you want to search for, and comma_separated_list is the list of strings in which you want to search.

The function returns the position of the search string within the list, or 0 if the string is not found. Note that the positions are 1-based.

Here is an example of how to use FIND_IN_SET:

SELECT FIND_IN_SET('apple', 'apple,banana,orange') as position;

This query will return the position of 'apple' within the list 'apple,banana,orange'. In this case, the result will be 1.

You can also use FIND_IN_SET in a WHERE clause to filter rows based on the presence of a string in a list. For example:

SELECT * FROM fruits WHERE FIND_IN_SET('apple', fruits_list) > 0;

This query will return all rows from the 'fruits' table where 'apple' is present in the 'fruits_list' column
