Easily back up Smartsheet data to SQL Server using the SSIS components for Smartsheet.
Using SQL Server as a backup for critical business data provides an essential safety net against loss. Backing up data to SQL Server enables business users to more easily connect that data with features like reporting, analytics, and more.
This example demonstrates how to use the CData SSIS Tasks for Smartsheet inside of a SQL Server SSIS workflow to transfer Smartsheet data into a Microsoft SQL Server database.
To get started, add a new Smartsheet source and SQL Server ADO.NET destination to a new data flow task.
Follow the steps below to save Smartsheet connection properties in a connection manager.
In the Connection Manager window, right-click and then click New Connection. The Add SSIS Connection Manager dialog is displayed. In the Connection Manager type menu, select Smartsheet. The CData Smartsheet Connection Manager is displayed. Configure connection properties.
Smartsheet uses the OAuth authentication standard. To authenticate using OAuth, you will need to register an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.
However, for testing purposes you can instead use the Personal Access Token you get when you create an application; set this to the OAuthAccessToken connection property.
SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.
Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:
1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.
2. Every database seller needs an approach to separate its item from others.
Right now, contrasts are noted where fitting.

Let’s say the chief credit and collections officer asks you to list down the names of people, their unpaid balances per month, and the current running balance and wants you to import this data array into Excel. The purpose is to analyze the data and come up with an offer making payments lighter to mitigate the effects of the COVID19 pandemic.
Do you opt to use a query and a nested subquery or a join? What decision will you make?
Before we do a deep dive into syntax, performance impact, and caveats, why not define a subquery first?
In the simplest terms, a subquery is a query within a query. While a query that embodies a subquery is the outer query, we refer to a subquery as the inner query or inner select. And parentheses enclose a subquery similar to the structure below:
SELECT col1 ,col2 ,(subquery) as col3 FROM table1 [JOIN table2 ON table1.col1 = table2.col2] WHERE col1 <operator> (subquery)
We are going to look upon the following points in this post:
As is customary, we provide examples and illustrations to enhance understanding. But bear in mind that the main focus of this post is on subqueries in SQL Server.
Now, let’s get started.
For one thing, subqueries are categorized based on their dependency on the outer query.
Let me describe what a self-contained subquery is.
Self-contained subqueries (or sometimes referred to as non-correlated or simple subqueries) are independent of the tables in the outer query. Let me illustrate this:
-- Get sales orders of customers from Southwest United States -- (TerritoryID = 4) USE [AdventureWorks] GO SELECT CustomerID, SalesOrderID FROM Sales.SalesOrderHeader WHERE CustomerID IN (SELECT [CustomerID] FROM [AdventureWorks].[Sales].[Customer] WHERE TerritoryID = 4)
As demonstrated in the above code, the subquery (enclosed in parentheses below) has no references to any column in the outer query. Additionally, you can highlight the subquery in SQL Server Management Studio and execute it without getting any runtime errors.
Which, in turn, leads to easier debugging of self-contained subqueries.
The next thing to consider is correlated subqueries. Compared to its self-contained counterpart, this one has at least one column being referenced from the outer query. To clarify, I will provide an example:
USE [AdventureWorks] GO SELECT DISTINCT a.LastName, a.FirstName, b.BusinessEntityID FROM Person.Person AS p JOIN HumanResources.Employee AS e ON p.BusinessEntityID = e.BusinessEntityID WHERE 1262000.00 IN (SELECT [SalesQuota] FROM Sales.SalesPersonQuotaHistory spq WHERE p.BusinessEntityID = spq.BusinessEntityID)
Were you attentive enough to notice the reference to BusinessEntityID from the Person table? Well done!
Once a column from the outer query is referenced in the subquery, it becomes a correlated subquery. One more point to consider: if you highlight a subquery and execute it, an error will occur.
And yes, you are absolutely right: this makes correlated subqueries pretty harder to debug.
To make debugging possible, follow these steps:
Isolating the subquery for debugging will make it look like this:
SELECT [SalesQuota] FROM Sales.SalesPersonQuotaHistory spq WHERE spq.BusinessEntityID = <constant value>
Now, let’s dig a little deeper into the output of subqueries.
Well, first, let’s think of what returned values can we expect from SQL subqueries.
In fact, there are 3 possible outcomes:
Let’s start with single-valued output. This type of subquery can appear anywhere in the outer query where an expression is expected, like the WHERE clause.
-- Output a single value which is the maximum or last TransactionID USE [AdventureWorks] GO SELECT TransactionID, ProductID, TransactionDate, Quantity FROM Production.TransactionHistory WHERE TransactionID = (SELECT MAX(t.TransactionID) FROM Production.TransactionHistory t)
When you use a MAX() function, you retrieve a single value. That’s exactly what happened to our subquery above. Using the equal (=) operator tells SQL Server that you expect a single value. Another thing: if the subquery returns multiple values using the equals (=) operator, you get an error, similar to the one below:
Msg 512, Level 16, State 1, Line 20 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Next, we examine the multi-valued output. This kind of subquery returns a list of values with a single column. Additionally, operators like IN and NOT IN will expect one or more values.
-- Output multiple values which is a list of customers with lastnames that --- start with 'I' USE [AdventureWorks] GO SELECT [SalesOrderID], [OrderDate], [ShipDate], [CustomerID] FROM Sales.SalesOrderHeader WHERE [CustomerID] IN (SELECT c.[CustomerID] FROM Sales.Customer c INNER JOIN Person.Person p ON c.PersonID = p.BusinessEntityID WHERE p.lastname LIKE N'I%' AND p.PersonType='SC')
And last but not least, why not delve into whole table outputs.
-- Output a table of values based on sales orders USE [AdventureWorks] GO SELECT [ShipYear], COUNT(DISTINCT [CustomerID]) AS CustomerCount FROM (SELECT YEAR([ShipDate]) AS [ShipYear], [CustomerID] FROM Sales.SalesOrderHeader) AS Shipments GROUP BY [ShipYear] ORDER BY [ShipYear]
Have you noticed the FROM clause?
Instead of using a table, it used a subquery. This is called a derived table or a table subquery.
And now, let me present you some ground rules when using this sort of query:
In this case, a derived table has the benefits of a physical table. That’s why in our example, we can use COUNT() in one of the columns of the derived table.
That’s about all regarding subquery outputs. But before we get any further, you may have noticed that the logic behind the example for multiple values and others as well can also be done using a JOIN.
-- Output multiple values which is a list of customers with lastnames that start with 'I' USE [AdventureWorks] GO SELECT o.[SalesOrderID], o.[OrderDate], o.[ShipDate], o.[CustomerID] FROM Sales.SalesOrderHeader o INNER JOIN Sales.Customer c on o.CustomerID = c.CustomerID INNER JOIN Person.Person p ON c.PersonID = p.BusinessEntityID WHERE p.LastName LIKE N'I%' AND p.PersonType = 'SC'
In fact, the output will be the same. But which one performs better?
Before we get into that, let me tell you that I have dedicated a section to this hot topic. We’ll examine it with complete execution plans and have a look at illustrations.
So, bear with me for a moment. Let’s discuss another way to place your subqueries.

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.
