Question

How can I select the row with the highest ID in MySQL? This is my current code:

SELECT * FROM permlog WHERE max(id)

Errors come up, can som

Answer 1

SELECT *
FROM permlog
WHERE id = ( SELECT MAX(id) FROM permlog ) ;

This would return all rows with highest id, in case id column is not constrained to be unique.

Answer 2

SELECT * FROM permlog ORDER BY id DESC LIMIT 0, 1

Answer 3

For MySQL:

SELECT *
FROM permlog
ORDER BY id DESC
LIMIT 1

You want to sort the rows from highest to lowest id, hence the ORDER BY id DESC. Then you just want the first one so LIMIT 1:

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement.

With one argument, the value specifies the number of rows to return from the beginning of the result set
