MySQL - How to select data by string length
Solution 1:
You are looking for CHAR_LENGTH() to get the number of characters in a string.
For multi-byte charsets LENGTH() will give you the number of bytes the string occupies, while CHAR_LENGTH() will return the number of characters.
Solution 2:
SELECT * FROM table
ORDER BY LENGTH(column);
Documentation on the LENGTH() function, as well as all the other string functions, is available here.
Solution 3:
Having a look at MySQL documentation for the string functions, we can also use CHAR_LENGTH() and CHARACTER_LENGTH() as well.
