#Sqlite order by date desc not working how to#

Note that when sorting in descending order in SQLite, NULLs are displayed last. Here's what the whole query should look like: To change the order to descending, use the DESC keyword after each column in the ORDER BY clause. This way, you can sort the rows in ascending order by date. You can use it when sorting the rows by date, that is, by year, numerical month, and day. This is how you convert a month name to a month number. After you finish converting all the values, remember to use the END keyword to close the CASE WHEN clause. Here, the column is exam_month, the current values in this column are ' January', ' February', …, ' December', and the new values are the numerical months 1, 2, …, 12. Then, after each WHEN, state the value in this column, use the THEN keyword, and specify the new value you'd like to assign instead of the old one.

After the CASE keyword, specify the name of the column. You can convert month names to numerical months with a CASE WHEN clause. To sort the rows by exam date, you need to sort first by year, then by numerical month (not month name), and finally by day. then I order it using this in another function: c.execute ('''SELECT FROM newslist ORDER BY date (dateposted) DESC''') It does absolutely nothing. The result looks like this (the rows are sorted in ascending order by exam_year, exam_month, and exam_day): subject Because it is not generated, but extracted from a scraped list.

The months are given in names, not in numbers.

In essence, understanding how to use the SQLite Order By clause can. You’ll find this particularly useful when you’re dealing with large datasets and need a quick way to sift through all that information. The exam table has the following columns: subject, exam_year, exam_month, and exam_day. The SQLite Order By clause is primarily used to sort the results in either ascending or descending order, based on one or more columns. Also, the rows with the same exam_date are displayed in random order (you may see Science second and Health third, or Health second and Science third). Note that in SQLite, NULLs are displayed first when sorting in ascending order and last when sorting in descending order. If you'd like to see the latest date first and the earliest date last, you need to sort in descending order. To generate row numbers we will use this: select, (select count() from mytable m1 where m1.id m2.id and m1.orderid > m2. You could also use the ASC keyword to make it clear that the order is ascending (the earliest date is shown first, the latest date is shown last, etc.). It seems that your date column is not of type datetime but varchar. SQLite will have this functionality built in version 3.2.5 but for now, we will work with a subquery. This way, you'll sort the data in ascending order by this column. Example 1: The exam table has two columns, subject and examdate.

Use the ORDER BY keyword and the name of the column by which you want to sort. Problem: You want to sort the rows by date. The result looks like this (the rows are sorted in ascending order by exam_date): Subject The exam table has two columns, subject and exam_date. You would have to take the Date Part to sort with first. ThenBy (c> c.Time.TimeOfDay) The Problem is that 'Time' contains Date and Time information, thus, already sorting completely.

In case you want to sort the result set by multiple columns, you use a comma (,) to separate two columns. Use the Date and TimeOfDay properties for the sort. In other words, it sorts the result set in the ascending order by default. Sqlite> SELECT * FROM COMPANY ORDER BY NAME, SALARY ASC įollowing is an example, which will sort the result in descending order by NAME.You want to sort the rows by date. If you don’t specify the ASC or DESC keyword, SQLite sorts the result set using the ASC option. Sqlite> SELECT * FROM COMPANY ORDER BY SALARY ASC įollowing is an example, which will sort the result in descending order by NAME and SALARY. ExampleĬonsider COMPANY table with the following records.įollowing is an example, which will sort the result in descending order by SALARY. Make sure whatever column you are using to sort, that column should be available in the column-list. You can use more than one column in the ORDER BY clause. Syntaxįollowing is the basic syntax of ORDER BY clause. SQLite ORDER BY clause is used to sort the data in an ascending or descending order, based on one or more columns.
