![]() ![]() I have not used it in a production environment, but now when I bench marked it, the extra sorting does not impact the performance. I use this technique when I manually write queries to examine the database for various things. If you need all columns, it is done this way: select t.* Now we have the newest result on the last row. It will still be sorted in descending order, and we are not satisfied with that, so we ask mysql to sort it one more time. This query below will sort the result descending and limit the result to 10 (that is the query inside the parenthesis). ![]() If you need to keep the result in ascending order, and still only want the 10 newest articles you can ask mysql to sort your result two times. In your situation, I recommend that you add desc to order by publish_date, if you want the newest articles, then the newest article will be first. ![]() Just as says, it will order all records, then get the first 20 rows.Īs it is so, you are guaranteed to get the 20 first published articles, the newer ones will not be shown. In other words, LIMIT row_count is equivalent to LIMIT 0, row_count. SELECT * FROM tbl LIMIT 5 # Retrieve first 5 rows With one argument, the value specifies the number of rows to return from the beginning of the result set: This statement retrieves all rows from the 96th row to the last: 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. Learn how to use the LIMIT feature and how to limit rows in this guide. SELECT * FROM tbl LIMIT 5,10 # Retrieve rows 6-15 The SQL Limit feature allows for SQL row limiting and performing Top-N queries. The offset of the initial row is 0 (not 1): With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants (except when using prepared statements). The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. ![]()
