Using Power of Web to Query Databases / Sources With Skyvia

Web technologies are moving at a pace that we can hardly keep up in pace. More and more of investments are going on in the space of web that even database developers like me find it interesting. In the same context, recently I was exploring on Skyvia (SQL SERVER – Integrate Your Data with Skyvia – Cloud ETL Solution) from ETL to how one might query and was surprised to see how some of these can be made useful.

This blog stems from a simple idea that was in my mind for a long time and I was struggling for a suitable solution till I saw what was available here. Think that you are a DBA and are on a vacation to a far-away land. You didn’t take your laptop along because you wanted to really enjoy your vacation times. Everything looks normal till you get an SMS from your management that something is wrong on one of your servers and they need 10-15 mins of your time to quickly resolve. Now with no laptop and all the cool things that you would have normally installed on your machine, how can you help your management with a few query support? Is it even possible? Assume you get to an internet kiosk and you want to do some amount of troubleshooting. How will you do? Well, there are a number of solutions.

One of the many available including the use of Skyvia to do query on your servers once you have done the simple step setup. In this example, I have used an SQL Server 2014 version available on a Cloud provider so that we can see what is going wrong.

Let us start by connecting to Skyvia and setting up our connections.

In my example, I am going to use the “SQL Server” source and will give all the credentials. Once done and tested, we must see this in our connections tab.

Once the connection setting seem to be in place, we are all set to run our queries on the backend. We can then head to the Query tab as shown below:

At this stage, I just linked the Query window to my connection that we created in our previous step. This started to list our all the tables that were available on my server. This was really a cool moment because I was able to work on my database in less than 5 mins via the web.

Obviously based on the permissions that I used to connect, the tables and objects are displayed. If there are 100’s of tables to work, then we can surely use the search to find the objects.

The next stage or table is our awesome query window. It is here that we can type in any SQL-92 query that needs to be fired against our database. Since I was wanting to know what was happening in my SQL Server system and what operators were functioning of few long running query, I used a DMV from SQL Server 2014 to check if it works. For my surprise, I was not disappointed.

This is the query result output based on the query that I was running in the backend.

node_id,physical_operator_name, SUM(row_count) row_count, SUM(estimate_row_count) AS estimate_row_count,
CAST(SUM(row_count)*100 AS FLOAT)/SUM(estimate_row_count)
FROM sys.dm_exec_query_profiles
GROUP BY node_id,physical_operator_name
ORDER BY node_id;

To know more about sys.dm_exec_query_profiles you can read from MSDN. I also talk about this DMV in my course at Pluralsight – SQL Server 2014 Administration New Features. The course is exhaustive in understanding some of these new capabilities of SQL 2014.

Coming back to our query, based on the output I was able to find out what was the query that was running behind the scene. As you can see this is a Dummy query without any filters or restriction on the columns selected. Hence we are seeing a number of Clustered Index Scan in our query output via the web.

FROM DimProduct
INNER JOIN DimProductSubcategory
ON DimProduct.ProductSubcategoryKey = DimProductSubcategory.ProductSubcategoryKey
INNER JOIN FactInternetSales
ON DimProduct.ProductKey = FactInternetSales.ProductKey

Once the query was identified, you can start looking at what is firing up the query and take corrective actions. Any normal SQL syntax can be fired like this via the web. It is simple and quite powerful to say the least.

The results from Skyvia is powerful that you can also use them to export to CSV format for later offline consumption. As part of simple testing, I also fired few DDL statements and was surprised to have almost everything I do via SQL Server Management Script window here via the web, anytime and anywhere I like.

And another thing I’d like to mention is that Skyvia Query is not just for SQL Server and other databases. Skyvia Query supports SQL for cloud CRMs, such as Salesforce, Dynamics CRM, etc, and allows using SELECT, INSERT, UPDATE and  DELETE statements against them. This enables admins, knowing SQL, work with cloud data in the same way as with SQL Server data.

Currently Skyvia is free for use. You can find more information on how to use their online SQL editor on the following page: Online SQL Query Editor for Cloud and Relational Data.

  • Thanks for pointing Skyvia out; I’ve learnt about your post from a LinkedIn share. (promo) We provide a forever free alternative named Invantive Query Tool. It supports across the cloud connections through a transparant tunneling protocol with Invantive Web Service and you can query REST, OData and XML using SQL. Update/insert/delete are only supported on some of these application-based web services. Of course the more traditional platforms are supported too like Teradata, Oracle and PostgreSQL. May I ask you to include it in some future post?

  • Hi Guys,

    Unable to connect Skyvia apps with SQL SERVER Tool.If you have any hands on experience in this pls share your inputs?.

  • I am getting struck in between sql server connections itself?.
    I am getting a error an “network related server incorrect instance name”
    Even I followed the steps in skyvia using free version
