I have a varchar field in my table and I want to sort it. But I need to handle this field as integer. Meaning if sort as text the order is "19,2,20" but I want to get the right order "2,19,20". Can anyone help me? I somehow didn't manage to run the query with CAST . I was always getting Error Code: 1064 near "DECIMAL" (or other numeric type that I chose). So, I found another way to sort varchar as numbers: SELECT * FROM mytable ORDER BY ABS(mycol) A bit simpler and works in my case. SELECT * FROM mytable ORDER BY CAST(mycol AS DECIMAL) Here is the solution SELECT * FROM MyTable ORDER BY ABS

I am trying to run this query in ascending order: SELECT title,project_index FROM projectdetail WHERE project_index BETWEEN 1 AND 6 ORDER BY title, project_index ASC; I need two columns in ascending order, but the above query returns results with only one column in ASC order. Lieven Keersmaekers Ascending order is the default for most (if not all) DBMS's so your statement is kind of weird in that respect but nevertheless, you can specify an order for each individual column by adding the specifier ASC or DESC to it. Your statement then would become SELECT title , project_index FROM

Which one comes first when MySQL processes the query? An example: SELECT pageRegions FROM pageRegions WHERE(pageID=?) AND(published=true) AND (publishedOn<=?) ORDER BY publishedON DESC LIMIT 1'; Will that return the last published pageRegion even if the record does not match the revision datetime IF LIMIT is applied after ORDER BY? Yes, it's after the ORDER BY. For your query, you'd get the record with the highest publishedOn, since you're ordering DESC , making the largest value first in the result set, of which you pick out the first one. The limit is always applied at the end of result

1. Bloggers blogger_id 1 2 3 2. Posts post_from_blogger_id 1 1 1 2 2 3 As you can see blogger №1 posted more than the others and blogger №3 less. The question is how to build a query that selects all bloggers and sorts them by the number of their posts? SELECT bloggers.*, COUNT(post_id) AS post_count FROM bloggers LEFT JOIN blogger_posts ON bloggers.blogger_id = blogger_posts.blogger_id GROUP BY bloggers.blogger_id ORDER BY post_count (Note: MySQL has special syntax that lets you GROUP BY without aggregating all values, it's intended for exactly this situation). Use subqueries. select * from (
