Select last row in MySQL
Keep in mind that tables in relational databases are just sets of rows. And sets in mathematics are unordered collections. There is no first or last row; no previous row or next row.
You'll have to sort your set of unordered rows by some field first, and then you are free the iterate through the resultset in the order you defined.
Since you have an auto incrementing field, I assume you want that to be the sorting field. In that case, you may want to do the following:
SELECT *
FROM your_table
ORDER BY your_auto_increment_field DESC
LIMIT 1;
See how we're first sorting the set of unordered rows by the your_auto_increment_field
(or whatever you have it called) in descending order. Then we limit the resultset to just the first row with LIMIT 1
.
Yes, there's an auto_increment in there
If you want the last of all the rows in the table, then this is finally the time where MAX(id)
is the right answer! Kind of:
SELECT fields FROM table ORDER BY id DESC LIMIT 1;
