SQL查询：按字符长度排序？

Question

Morning, is it possible to order sql data rows by the length of characters?

eg SELECT * FROM database ORDER BY data.length()

Answer 1

I think you want to use this: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_char-length

SELECT * FROM table ORDER BY CHAR_LENGTH(field)

You can use just simply LENGTH(), but beware, because it counts the byte number (which won't give you the expected result with multibyte strings).

Answer 2

SELECT * FROM database ORDER BY Len(data)

Answer 3

SELECT * FROM table ORDER BY length(data) desc

数据是varchar字段的位置

Answer 4

SELECT * FROM YourTable ORDER BY LENGTH(Column_Name) DESC

例如;

SELECT * FROM Customer ORDER BY LENGTH(CustomerName) DESC

Answer 5

对于任何使用Sqlite的人

SELECT * FROM table ORDER BY LENGTH(field) DESC
