![]() We can also see the two 38 year old musicians with their cities properly sorted in alphabetical order. We can see there are three 19 year old musicians with their respective cities alphabetically sorted in the table. In this new musician example, we can sort the age and city columns in ascending order. You can also sort multiple columns in ascending order in the same command. If we wanted to sort the data by city, then we can use this syntax. You can see that the names are now sorted alphabetically and the id's are no longer in the correct ascending order. The * character tells the computer to select all of the columns in the table. If we wanted to sort the name column in ascending order, then we would have to use this syntax: SELECT * FROM musicians Right now, this table is sorted automatically by id in ascending order. In this example, we have a table of musicians with the columns of id, name, age, instrument and city: The FROM clause in SQL specifies which table we want to list. The SELECT statement in SQL tells the computer to get data from the table. If you want to sort by descending order, then you have to use the DESC keyword. This is the basic syntax to sort your data in ascending order: SELECT columns FROM table Use it with an ORDER BY clause to sort the rows in ascending order by date.In this article, I will show you a few code examples on how you can sort your data in ascending order using the ORDER BY clause in SQL. STR_TO_DATE(CONCAT(exam_year, ' ', exam_month, ' ', exam_day), '%Y %M %d') %Y stands for year, %M stands for month (its full name, not a number), and %d stands for day. The second argument of this function is the date format. Then, you need to convert this string to a date using the STR_TO_DATE(date_string, '%Y %M %d') function. Since you'd like to get a string in the 'Year Month Day' format, the arguments are exam_year, exam_month, exam_day, and the spaces between them. You don't need to cast numbers to strings. The CONCAT() function combines all the arguments into one string. But first, you need to create a string using the CONCAT() function:ĬONCAT(exam_year, ' ', exam_month, ' ', exam_day) If you have a date stored as a string in the 'Year Month Day' format, you can cast it to a date using STR_TO_DATE(date_string, '%Y %M %d'). To do this, use the STR_TO_DATE() function. To sort by date, create date values from the year, the month, and the day values. The result looks like this (the rows are sorted in ascending order by exam_year, exam_month, and exam_date): subject ORDER BY STR_TO_DATE(CONCAT(exam_year, ' ', exam_month, ' ', exam_day), '%Y %M %d') The months are given in names, not in numbers. ![]() ![]() The exam table has the following columns: subject, exam_year, exam_month, and exam_day. ![]() Also, the rows with the same exam_date are displayed in random order (you may see Science third and Health fourth, or Health third and Science fourth). Note that in MySQL, 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. 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.). This way, you'll sort the data in ascending order by this column. Use the ORDER BY keyword and the name of the column by which you want to sort. 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 want to sort the rows by date in MySQL.
