I have a table who looks something like this:
USERNAME DATA DATETIME
Jhon text1 2010-06-01 16:29:43
Mike text2 2010-06-01 16:29:22
Silver text3 2010-05-23 06:19:12
Jhon text1 2010-02-01 01:02:00
What is the php command if i want the DATA from the LAST entry made by Jhon ??? Thanks!
SELECT data FROM table WHERE username = 'Jhon' ORDER BY datetime DESC LIMIT 1
“ datetime desc排序”和“ limit 1”配对将为您提供最后的输入。
