Sorting rows by one column in descending order In the output, we see the results of using the ORDER BY command: all the actors’ names are sorted in alphabetical order by the first name column. Enter the following query: SELECT actor_id, first_name, last_name In dbForge Studio for PostgreSQL, click New SQL.Ģ. We also want to sort them by their first names in ascending order.ġ. Today, we need to retrieve the first and last names of the actors we work with.

Let us imagine our childhood dreams are finally true and we are working in the movie production industry. If there aren’t any additional parameters, Postgres shows the selected results sorted in the default ascending order. Using PostgreSQL ORDER BY clause to sort rows by defaultĪs we already know, Postgres ORDER BY ASC and Postgres ORDER BY are pretty much the same thing. Then, on opening the IDE for the first time, fill in the Database Connection Properties.Ĥ.

In this article, we are going to use dbForge Studio for PostgreSQL to demonstrate the various examples of how to use the ORDER BY command. This article will review the most common examples of data sorting, from the simplest, standard scenarios to more complicated ones requiring additional consideration. However, there might be some pitfalls not to fall into when things are getting more diverse and complicated. The process can seem quite simple when you order the standard data in columns in ascending or descending order. Now, let us examine the ORDER BY performance with examples.

Proceeds to SELECT to define the columns we are looking for.

Starts with the FROM clause to figure out where to look.

The statement works according to the following pattern: Unlike ASC, we must define DESC explicitly when we want the Postgres ORDER BY command to return the results in descending order.

DESC is a command used to sort the results in descending order.

Adding this condition is optional, as it is the default way to sort the query results in Postgres.

ASC is a command used to sort the results in ascending order.

WHERE is an optional condition that needs to be met when retrieving records.

We must specify at least one table in the query.

Tables – particular tables we are going to retrieve the records from.

Columns – list of columns we retrieve using the SELECT statement.

The syntax of the ORDER BY clause used in the SELECT query is as follows: SELECT columns This PostgreSQL sort by task may involve various criteria and conditions we’ll review further.

Using PostgreSQL ORDER BY clause to sort rows by dateīefore we start diving deeply into different scenarios of using the PostgreSQL ORDER BY command, let’s take out time to consider the basics.

Set limits for the results retrieved by PostgreSQL ORDER BY.

Sorting rows by one column in descending order.

Using PostgreSQL ORDER BY clause to sort rows by default.

Therefore, we introduce the ORDER BY query in dbForge Studio for PostgreSQL – it sorts records retrieved by the SELECT statement. We must perform additional data manipulation to get results in the desired order. The SELECT command returns results in no particular order. The PostgreSQL system we will be dealing with in this article is not an exception. No matter which RDBMS you are using, you will need this command. The SELECT statement is the most widely used SQL method to find and retrieve data from databases according to particular criteria.
