mysql - offset problem
I recently posted a question about getting last 3 results in table in the correct order. I now want the get all comments apart from the last 3 in the correct order.
Here is my syntax;
SELECT *
FROM (SELECT *
FROM $table
ORDER BY ID DESC
OFFSET 3) AS T
ORDER BY TIME_STAMP
The error I am receiving is:
You have an error in your SQL syntax; check the manual that corresponds to your M开发者_开发技巧ySQL server version for the right syntax to use near 'OFFSET, 3) AS T ORDER BY TIME_STAMP' at line 1
I can't seem to get it to work. Any help much appreciated.
According to the MySQL Documentation:
To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:
They recommend you use a query such as:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
So in your case, you should try:
SELECT *
FROM (SELECT *
FROM $table
ORDER BY ID DESC
LIMIT 3,18446744073709551615) AS T
ORDER BY TIME_STAMP
Note that you can also use the PostgreSQL compatible version using the keyword OFFSET
:
SELECT *
FROM (SELECT *
FROM $table
ORDER BY ID DESC
LIMIT 18446744073709551615 OFFSET 3) AS T
ORDER BY TIME_STAMP
Just in case you are wondering, 18446744073709551615 = 2^64 - 1
.
You can't use OFFSET without a LIMIT.
A little bulky, but that query worked for me, and not worked without an redundant internal subquery (mysql 5.0.90)
select * from $table
where id not in (
select id from (
select id from languages order by id DESC LIMIT 3
) l1
) order by time_stamp
Was having the same issue because I copied:
OFFSET :offset LIMIT :limit
from an existing query, which is valid in Postgres.
Apparently the order matters in MySQL, so reversing the order worked for me:
LIMIT :limit OFFSET :offset
