MySQL is smart in that if you specify a LIMIT 5000 in your query, and it is possible to produce that result without generating the whole result set first, then it will not build the whole result. For instance, the following query: SELECT * FROM table ORDER BY column LIMIT 5000 This query will need … Read more
Create a Game model which extends Eloquent and use this: Game::take(30)->skip(30)->get(); take() here will get 30 records and skip() here will offset to 30 records. In recent Laravel versions you can also use: Game::limit(30)->offset(30)->get();
Prior to 5.5.6, LIMIT could not be parameterized in MySQL stored procedures. You’d need to build the query dynamically and execute it. In 5.5.6 and above, you can just pass the stored procs parameters as arguments to LIMIT and OFFSET as long as they are INTEGER.
As of oracle 12c, you could use the top N queries. SELECT fieldA,fieldB FROM table ORDER BY fieldA OFFSET 5 ROWS FETCH NEXT 14 ROWS ONLY; http://www.oracle-base.com/articles/12c/row-limiting-clause-for-top-n-queries-12cr1.php
The first query fails if any row has quantity IS NULL (as Gordon demonstrates). The second query only fails if all rows have quantity IS NULL. So it should be usable in most cases. (And it’s faster.) Postgres 13 or newer Use the standard SQL clause WITH TIES: SELECT id FROM product ORDER BY quantity … Read more
Postgres 13 finally adds WITH TIES . See: Get top row(s) with highest value, with ties There is no WITH TIES clause up to PostgreSQL 12, like there is in SQL Server. In PostgreSQL I would substitute this for TOP n WITH TIES .. ORDER BY <something>: WITH cte AS ( SELECT *, rank() OVER … Read more
Prior to 12.1, Oracle does not support the LIMIT or OFFSET keywords. If you want to retrieve rows N through M of a result set, you’d need something like: SELECT a.* FROM (SELECT b.*, rownum b_rownum FROM (SELECT c.* FROM some_table c ORDER BY some_column) b WHERE rownum <= <<upper limit>>) a WHERE b_rownum >= … Read more
It will order first, then get the first 20. A database will also process anything in the WHERE clause before ORDER BY.
From the MySQL Manual on LIMIT: 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: SELECT * FROM tbl LIMIT 95, 18446744073709551615;
If you want just a first selected row, you can: select fname from MyTbl where rownum = 1 You can also use analytic functions to order and take the top x: select max(fname) over (rank() order by some_factor) from MyTbl
