I have got a MySql query that orders me results by no column (int, can be null). Simple example: SELECT * FROM table ORDER BY no ASC I would like to get a resultset sorted like 1, 2, 3, 10, 52, 66, NULL, NULL, NULL but I get NULL, NULL, NULL, 1, 2, 3, 10, 52, 66 Is it possible with SQL query ? Could you try this? ORDER BY ISNULL(no),no; You can use a CASE statement to tweak ordering: SELECT * FROM table ORDER BY case when no is null then 2 else 1 end, no This orders on "nullableness" first, and no second. Thompson SELECT * FROM table ORDER BY ISNULL(field), field ASC; SELECT * FROM table ORDER

I have a table as below Rate Effective_Date ---- -------------- 5.6 02/02/2009 5.8 05/01/2009 5.4 06/01/2009 5.8 12/01/2009 6.0 03/15/2009 I am supposed to find the all rates that are effective for current date and after it. So to get the current effective rate, i use SELECT TOP 1 * from table where effective_date < '05/05/2009' order by effective date desc for the rates after the current date the query is SELECT * from table where effective_date > '05/05/2009' To combine these two result i use a union as SELECT TOP 1 * from table where effective_date < '05/05/2009' order by effective date

Is there a way in SQL (MySQL) to do a "round robin" ORDER BY on a particular field? As an example, I would like to take a table such as this one: +-------+------+ | group | name | +-------+------+ | 1 | A | | 1 | B | | 1 | C | | 2 | D | | 2 | E | | 2 | F | | 3 | G | | 3 | H | | 3 | I | +-------+------+ And run a query that produces results in this order: +-------+------+ | group | name | +-------+------+ | 1 | A | | 2 | D | | 3 | G | | 1 | B | | 2 | E | | 3 | H | | 1 | C | | 2 | F | | 3 | I | +-------+------+ Note that the table may have many rows, so I can't do the ordering in the application

I have a search form which searches a site content table to pull back appropriate results. I want to search the title and content fields and pull back results in order of relevance.

I

Lets say I have a plant table: id fruit 1 banana 2 apple 3 orange I can do these SELECT * FROM plant ORDER BY id; SELECT * FROM plant ORDER BY fruit DESC; which does the obvious thing. But I was bitten by this, what does this do? SELECT * FROM plant ORDER BY SUM(id); SELECT * FROM plant ORDER BY COUNT(fruit); SELECT * FROM plant ORDER BY COUNT(*); SELECT * FROM plant ORDER BY SUM(1) DESC; All these return just the first row (which is with id = 1). What's happening underhood? What are the scenarios where aggregate function will come in handy in ORDER BY ? Your results are more clear if you
