So, this was a very basic introduction to SQL, Postgres, and Azure Data Studio. Let's create a simple custom function using SQL.Įxecuting this SQL will result in function creation and we can use this function as per our needs.Īnd here is how we can use it e.g. There are many functions available out of the box and we can create custom functions as well. Another built-in function is random() which returns some random value as shown below: We used now() function earlier which returns the current time. Postgres has a lot of functions which we can use. The above query tells Postgres to grab the 3 users but skip the first 2 essentially making it a paging query. The other keyword which is very helpful and normally goes with limit is the keyword offset and used for pagination purposes: To limit the result, Postgres uses limit as shown below (SQL-server uses TOP keyword): The following query shows the result and we can see that registeredat column has a default value as well. Let's insert and select some data using SQL.

if we want to alter a column in our table, the following is the syntax.Īnother example showing renaming a column: If your database can be offline while the backup file is created, copied, and restored, we recommend that you use native backup and restore to migrate it to RDS. The if exists set up guards against error if the table doesn’t exist. This is also very straight forward: Try not to do that in your production database :)
#Azure data studio backup serial#
The keyword serial is PostgreSQL specific and it set up an auto-incrementing value and that is the typical way for the primary-key. In DDL (Data Definition Language) SQL is very simple in PostgreSQL. In this section, we will refresh some basic SQL knowledge and some queries and their purposes.
I use the notebook window from the Azure Data Studio (ADS) and execute the following SQL which created the database as intended.īasic SQL Queries (Create, Alter, Select and Drop Basics) Ok, let's start something simple and create a database. The following screenshot shows that I am connected to Postgres server. You can also use pgAdmin or any other tool as u wish. I have installed the PostgreSQL database on my machine and I also have installed Azure Data Studio which I will use to execute various queries for the database. If you haven’t used ADS before, give it a try and you will like it. You can execute queries via a query window or via a notebook window. You can learn more about it from the official website on this link.ĪDS also has notebooks that are similar to Jupiter notebooks for python and other languages and are great for combining formatted text with code.
It’s engineered with the data platform user in mind, with the built-in charting of query result sets and customizable dashboards.

It is very easy to install and offers a modern editor experience with IntelliSense, code snippets, source control integration, and an integrated terminal. Implement thread.I have already written a few posts about PostgreSQL and this time I would like to take a step back and discuss some of the basics and at the same time share with you my experience of using Azure Data Studio.Īzure Data Studio is a cross-platform database tool for data professionals using the Microsoft family of on-premises and cloud data platforms on Windows, macOS, and Linux.Data Science vs Big Data vs Data Analytics.Select Ctrl+T to open the Task History and check the status of the restore procedure.Restore backup is seen in this screenshot.Then choose Restore from the drop-down menu.
To restore the backup file to a new database, type TutorialDB Restored in the Target database box in the Destination section.In the Backup file path box, click the ellipses (.) and choose the most recent backup file for TutorialDB.In the Restore from box, choose Backup file.
