This blog post explores the applications of the Pivot and Unpivot data manipulation techniques within the context of the Oil and Gas industry. These powerful techniques are commonly used in data analytics and data science to summarize and transform data and can be especially useful for professionals in this industry who need to analyze large datasets. Through the use of SQL Server, the blog will demonstrate how these techniques can be effectively applied to the Oil and Gas industry to streamline data analysis and improve decision-making.
Pivot and Unpivot are powerful data manipulation techniques used to summarize and transform data. These techniques are widely used in the data analytics and data science fields. In this blog, we will discuss how these techniques can be applied to the Oil and Gas industry using SQL Server.
Understanding the Different Concept Types in Pivot and Unpivot
Pivot
Pivot is used to transform data from a row-based format to a column-based format. It allows data to be summarized and grouped based on columns.
Example: Consider the following data table that shows the sales of different products for different months.
The data can be transformed using the UNPIVOT operator as follows:
SELECT Product, Month, Sales FROM Sales UNPIVOT ( Sales FOR MonthIN (January, February, March) ) AS UnpivotTable;
The result will be as follows:
Product | Month | Sales -----------------------------Product A | January | 100 Product A | February | 200 Product A | March | 300 Product B | January | 400 Product B | February | 500 Product B | March | 600
Real-World Examples in the Oil & Gas Industry
Using SQL Server:
CREATETABLEOilProduction ( Country varchar(50), January int, February int, March int);
1. Display the total oil production of each country for the first quarter of the year (January to March).
View Answer
SELECT Country, SUM(January + February + March) AS TotalProduction FROM OilProduction GROUP BY Country;
2. Display the oil production of each country for each month.
View Answer
SELECT Country, Month, Sales FROM OilProduction UNPIVOT ( Sales FOR MonthIN (January, February, March) ) AS UnpivotTable;
3. Display the oil production of each country in a column-based format.
View Answer
SELECT*FROM (SELECT Country, Month, Sales FROM (SELECT Country, January, February, March FROM OilProduction) AS SourceTable UNPIVOT ( Sales FOR MonthIN (January, February, March) ) AS UnpivotTable) AS FinalTable PIVOT ( SUM(Sales) FOR MonthIN ([January], [February], [March]) ) AS PivotTable;
Most Commonly Asked Interview Question in Pivot and Unpivot
Q: What is the difference between Pivot and Unpivot?
A: Pivot and Unpivot are data manipulation techniques used to summarize and transform data. The main difference between these techniques is the direction of transformation. Pivot is used to transform data from a row-based format to a column-based format. Unpivot is used to transform data from a column-based format to a row-based format.
I have used these techniques in a previous project where I was required to analyze the sales of different products for different months. I used Pivot to summarize the data and transform it into a column-based format. This allowed me to easily analyze the sales of each product for each month. I also used Unpivot to transform the data back into a row-based format so that I could perform further analysis.

This approach provides greater flexibility and adaptability, as it allows developers to construct SQL statements based on user inputs or other conditions. By utilizing dynamic SQL, developers can build applications that are more responsive to user needs and provide a more personalized experience. In this blog, we will delve into the different types of dynamic SQL and provide examples from the Telecommunications industry, demonstrating how dynamic SQL can be used to create more efficient and effective database applications. Whether you are a seasoned developer or just starting with SQL Server, this blog will help you master dynamic SQL and unleash its full potential.
Dynamic SQL is a technique used in SQL Server where the SQL statement is generated and executed at runtime. This allows you to write code that is more flexible and adaptable, as you can construct and execute SQL statements based on user inputs or other conditions. In this blog, we’ll explore the different types of dynamic SQL and provide examples from the Telecommunications industry.
Types of Dynamic SQL
Dynamic SELECT Statement
A dynamic SELECT statement is used to generate a SELECT statement at runtime, based on the inputs or conditions. For example, in the Telecommunications industry, you may need to generate a SELECT statement to retrieve data for a specific customer based on their customer ID.
Here’s an example of how you would generate a dynamic SELECT statement in SQL Server:
DECLARE @customerID INT=123; DECLARE @sql NVARCHAR(MAX); SET @sql =N'SELECT * FROM Customers WHERE CustomerID = '+CAST(@customerID ASNVARCHAR(10)); EXEC sp_executesql @sql;
In this example, the @customerID variable is set to 123, and the dynamic SELECT statement is generated using the @sql variable. The sp_executesql system stored procedure is used to execute the dynamic SQL statement.
Dynamic INSERT Statement
A dynamic INSERT statement is used to insert data into a table at runtime. For example, in the Telecommunications industry, you may need to insert data for a new customer into the Customers table.
Here’s an example of how you would generate a dynamic INSERT statement in SQL Server:
In this example, the @firstName and @lastName variables are set to ‘John’ and ‘Doe’, respectively, and the dynamic INSERT statement is generated using the @sql variable. The sp_executesql system stored procedure is used to execute the dynamic SQL statement.
Dynamic UPDATE Statement
A dynamic UPDATE statement is used to update data in a table at runtime. For example, in the Telecommunications industry, you may need to update the last name of a customer based on their customer ID.
Here’s an example of how you would generate a dynamic UPDATE statement in SQL Server:
DECLARE @customerID INT=123; DECLARE @lastName NVARCHAR(50) ='Smith'; DECLARE @sql NVARCHAR(MAX); SET @sql =N'UPDATE Customers SET LastName = '''+ @lastName +''' WHERE CustomerID = @customerID
Real-World Example Questions in Telecommunications Industry
1. Write a script to generate a table named Customers with columns CustomerID, FirstName, LastName, and PhoneNumber. Populate the table with sample data.
2. Write a dynamic SQL statement to retrieve all customers with the last name Doe.
View Answer
DECLARE @lastName NVARCHAR(50) ='Doe'; DECLARE @sql NVARCHAR(MAX); SET @sql =N'SELECT * FROM Customers WHERE LastName = '''+ @lastName +''''; EXEC sp_executesql @sql;
3. Write a dynamic SQL statement to update the phone number for customer with ID 123 to 555-555-1215.
View Answer
DECLARE @customerID INT=123; DECLARE @phoneNumber NVARCHAR(20) ='555-555-1215'; DECLARE @sql NVARCHAR(MAX); SET @sql =N'UPDATE Customers SET PhoneNumber = '''+ @phoneNumber +''' WHERE CustomerID = '+CAST(@customerID ASNVARCHAR(10)); EXEC sp_executesql @sql;
Interview Question and Answer
Q: What is Dynamic SQL and how have you used it in a project?
A: Dynamic SQL is a technique used in SQL Server where the SQL statement is generated and executed at runtime. I have used dynamic SQL in a project where I was building a reporting system for a Telecommunications company. The system allowed users to generate reports based on various criteria such as customer information, call data, and billing data. To achieve this, I used dynamic SQL to generate SELECT statements based on the user inputs and then executed those statements to retrieve the data. This approach allowed me to write more flexible and adaptable code that could handle different reporting requirements.
Conclusion
In conclusion, dynamic SQL is a powerful technique in SQL Server that allows you to generate and execute SQL statements at runtime. By using dynamic SQL, you can write code that is more flexible and adaptable, making it easier to handle different scenarios and requirements.

The SQL Partition By Clause is a crucial tool in managing and analyzing large datasets in SQL Server and other relational database management systems. By leveraging this feature, it becomes possible to segment a vast result set into more manageable portions based on one or more columns in the data. This can lead to significant improvements in query execution times and make it easier to perform in-depth data analysis. Whether you are working with massive datasets or need to optimize your query performance, the SQL Partition By Clause is a powerful tool that can help you achieve your goals.
SQL Partition By Clause is an important concept in SQL Server and other relational database management systems. It is used to divide a large result set into smaller, manageable parts based on one or more columns in the data. This can improve the performance of query execution and make it easier to analyze data.
Different Concept Types in SQL Partition By Clause
There are several different types of partitions that can be created using the Partition By clause. Let’s look at each of these in detail, using examples from the Pharmaceutical industry.
Row Number Partition
This type of partition assigns a unique row number to each row in the result set. This is useful for pagination, as you can retrieve a specific range of rows based on the row number.
SELECTROW_NUMBER() OVER (PARTITIONBY ProductName ORDER BY SaleDate) AS RowNumber, ProductName, SaleDate, SaleAmount FROM Sales WHERE Industry ='Pharmaceutical'
In the above example, we are using the Row Number partition to assign a unique row number to each row in the result set. The partition is based on the ProductName column and the rows are ordered by SaleDate.
Rank Partition
This type of partition assigns a rank to each row in the result set, based on one or more columns. Rows with the same values will receive the same rank.
SELECTRANK() OVER (PARTITIONBY ProductName ORDER BY SaleAmount DESC) AS Rank, ProductName, SaleDate, SaleAmount FROM Sales WHERE Industry ='Pharmaceutical'
In the above example, we are using the Rank partition to assign a rank to each row in the result set. The partition is based on the ProductName column and the rows are ordered by SaleAmount in descending order.
Dense Rank Partition
This type of partition assigns a dense rank to each row in the result set, based on one or more columns. Rows with the same values will receive the same rank, and there will not be any gaps in the ranks.
SELECTDENSE_RANK() OVER (PARTITIONBY ProductName ORDER BY SaleAmount DESC) AS DenseRank, ProductName, SaleDate, SaleAmount FROM Sales WHERE Industry ='Pharmaceutical'
In the above example, we are using the Dense Rank partition to assign a dense rank to each row in the result set. The partition is based on the ProductName column and the rows are ordered by SaleAmount in descending order.
Real-World Example Questions in Pharmaceutical Industry
Before we move on to the example questions, let’s create the script to generate the table and records needed to answer the questions.

3. What is the total cost of pharmaceutical products sold in each city over the last 10 years?
View Answer
WITH Sales_Data AS (SELECT City,Year,SUM(Product_Cost) OVER (PARTITIONBY City) AS Total_CostFROM Pharmaceutical_Product_SalesWHEREYear>=YEAR(GETDATE() -10))SELECT City, Total_CostFROM Sales_DataGROUP BY City, Total_Cost;
Most Commonly Asked Interview Question and Answer
Q: Can you explain the use of Over(Partition By) clause in SQL?
A: The Over(Partition By) clause is a function in SQL that allows you to perform a calculation over a set of rows that are defined by a partition. In other words, the Partition By clause allows you to divide the rows of a result set into groups based on the values in one or more columns.
For example, in a previous project, I had to analyze sales data for a pharmaceutical company. I used the Over(Partition By) clause to group the sales data by city and calculate the average salary of pharmaceutical sales representatives for each city. This allowed me to easily identify the cities with the highest and lowest average salaries.
In summary, the Over(Partition By) clause is a powerful tool for data analysis and can be used in a variety of scenarios, such as calculating running totals, moving averages, and percentiles.
This gave us a clear picture of the cost of each medication and helped us make informed decisions about which medications to prescribe to our patients.
