If the ORDER BY clause references a column alias from the select list, the column alias must be used standalone, and not as a part of some expression in ORDER BY clause, for example: SELECT SCHEMA_NAME(schema_id) AS SchemaName FROM sys.objects The column names referenced in the ORDER BY clause must correspond to either a column or column alias in the select list or to a column defined in a table specified in the FROM clause without any ambiguities. That is, the result set is sorted by the first column and then that ordered list is sorted by the second column, and so on. The sequence of the sort columns in the ORDER BY clause defines the organization of the sorted result set. A sort column can be specified as a name or column alias, or a nonnegative integer representing the position of the column in the select list. Specifies a column or expression on which to sort the query result set. That is how to use the ORDER BY clause in SQL to sort data in ascending order.To view Transact-SQL syntax for SQL Server 2014 (12.x) and earlier versions, see Previous versions documentation. If you want to sort some of the data in ascending order and other data in descending order, then you would have to use the ASC and DESC keywords. If you want to sort multiple columns in ascending order then you would list the columns you want to sort next to the ORDER BY clause. The * character tells the computer to select all of the columns in the table. If you want to sort by descending order then you also have to use the DESC keyword. You can sort your table data in ascending order using the ORDER BY clause in SQL. Even though they are the same age, Jess is higher in the table because flute comes before trumpet alphabetically. We see the same situation with Jess and Dave. But Oscar is the top result because drums comes before trombone alphabetically. We can see in our table that both Oscar and Jenny are the oldest. We have to use both the ASC and DESC keywords next to the column names to tell the computer how to sort the data. Here is the syntax: SELECT * FROM musicians In this new musician example, we want to sort the age column in descending order and the instrument column in ascending order. If we wanted to sort some of the data in ascending order and other data in descending order, then we would have to use the ASC and DESC keywords. 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. 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 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.
