Introduction to Power Query

Power Query is a data preparation and transformation tool that is available as a part of Microsoft Excel and Power BI. It allows you to import, transform, and integrate data from a wide range of sources, including databases, spreadsheets, text files, and web services.

Power Query has a simple and intuitive user interface that allows you to easily connect to data sources, preview and explore data, and apply transformations to shape and clean the data as needed. It also includes a wide range of built-in transformations and functions that can be used to manipulate data and create custom columns and measures.

One of the main benefits of Power Query is that it allows you to perform data preparation tasks quickly and easily, without the need for complex coding or SQL queries. It also has the ability to store the steps of your data transformation process as a "query," which can be reused and shared with others.

Power Query can be used in a variety of scenarios, including data cleaning, data integration, and data analysis. It is a powerful tool for anyone who needs to work with data and can help you save time and effort when preparing data for analysis or reporting.

Power Query or SQL? 

Power Query and SQL are both tools that are used to extract, transform, and load data. They can be used to extract data from various sources, clean and transform the data, and load it into a target system such as Power BI or a data warehouse.

Power Query is a tool that is part of the Microsoft Power BI suite of tools. It is used to extract, transform, and load data from a wide range of sources, including databases, spreadsheets, and web services. Power Query provides a user-friendly interface and a range of data transformation features, making it easy to extract, transform, and load data without writing complex code.

SQL (Structured Query Language) is a programming language that is used to manage and manipulate data in a database. It is the standard language for interacting with relational databases and is used to create, modify, and query databases. SQL is a more powerful and flexible tool than Power Query, but it requires more programming skills and knowledge of database concepts.

In general, Power Query is the best choice for users who want an easy-to-use tool for extracting, transforming, and loading data, while SQL is better suited for more advanced users who need more control over the data transformation process. Both tools can be useful depending on your specific needs and skill level.

How to append queries in Power BI

To append queries in Power Query, you can use the "Append" transformation, which allows you to combine two or more tables by adding the rows from one table to the bottom of another table. Here is how you can do this in Power Query: 1. Open the Power Query Editor and select the tables that you want to append. 2. Click the "Home" tab in the ribbon, and then click the "Append" button in the "Combine" group. 3. In the "Append" dialog box, select the table that you want to append to the bottom of the other table, and then click "OK". Power Query will create a new query that combines the two tables by appending the rows from one table to the bottom of the other. You can then apply additional transformations as needed, and load the resulting table back into your workbook or report. Alternatively, you can also use the "Merge" transformation to combine two tables by matching rows from one table with rows from the other table ...
