Sqlite order by asc and desc8/30/2023 Note: this functionality (numbering columns instead of using names) is supported by Mode, but not by every flavor of SQL, so if you're using another system or connected to certain types of databases, it may not work. For example, the following query is exactly equivalent to the previous query: SELECT * The numbers will correspond to the order in which you list columns in the SELECT clause. You can see the difference the order makes by running the following query: SELECT *įinally, you can make your life a little easier by substituting numbers for column names in the ORDER BY clause. Finally, the results are sorted by the first column mentioned ( year), then by year_rank afterward. Second, the DESC operator is only applied to the column that precedes it. You can see a couple things from the above query: First, columns in the ORDER BY clause must be separated by commas. This example query makes the most recent years come first but orders top-ranks songs before lower-ranked songs: SELECT * This is particularly useful if your data falls into categories and you'd like to organize rows by date, for example, but keep all of the results within a given category together. Try it out See the answer Ordering data by multiple columns Write a query that returns all rows from 2012, ordered by song title from Z to A. If you'd like your results in the opposite order (referred to as descending order), you need to add the DESC operator: SELECT * Here's an example using a numerical column: SELECT * If you order a numerical column in ascending order, it will start with smaller (or most negative) numbers, with each successive row having a higher numerical value than the previous. This is referred to as ascending order, and it's SQL's default. You'll notice that the results are now ordered alphabetically from a to z based on the content in the artist column. Now let's see what happens when we order by one of the columns: SELECT * First, take a look at how the table is ordered by default: SELECT * FROM tutorial.billboard_top_100_year_end The ORDER BY clause allows you to reorder your results based on the data in one or more columns. Once you've learned how to filter data, it's time to learn how to sort data. This lesson uses data from the Billboard Music Charts. Starting here? This lesson is part of a full-length tutorial in using SQL for Data Analysis.
