how to select the 5 latest row from my mysql

Question

I wanted to know the sql command to retrieve 5 latest row from my table? Below is my sql query. How am I going to do, in order it can select the 5 latest row base on row

Answer 1

The best way to do this is to add a row number and then reverse your query based on that, since we don't have any guarantees that your datetime field increments chronologically; and I'm also assuming that by 5 latest rows you mean the last 5 added to the table, not the 5 with the most recent datetime.

SELECT
    lat
    , lng
    , DATE_FORMAT(datetime,'%W %M %D, %Y %T') AS datetime
    , @rownum:=@rownum+1 `RowNum`
FROM
    markers1
    , (SELECT @rownum:=0) `r`
WHERE 1
ORDER BY RowNum DESC
LIMIT 5
