Commonly used tasks in the Query Editor: Filtering Data : Narrowing down data sets based on specific criteria. Sorting Data : Arranging data in ascending or descending order. Grouping Data : Combining rows that have the same values in specified columns. Merging Queries : Combining data from different queries into a single query. Appending Queries : Adding rows from one query to another. Removing Columns : Deleting unnecessary columns from the data set. Changing Data Types : Converting data types to ensure consistency and accuracy. Creating Custom Columns : Adding new columns based on calculations or conditions. Pivoting and Unpivoting Columns : Transforming data from rows to columns and vice versa. Splitting Columns : Dividing a column into multiple columns based on delimiters.

Absolutely, I'd be happy to shed some light on commonly used tasks in the Query Editor. Here are a few tasks that are frequently performed within a Query Editor: 1. Data Cleaning : This involves tasks such as removing duplicates, handling missing values, correcting data inconsistencies, and transforming data to ensure it's accurate and consistent. 2. Filtering and Sorting Data : Query Editors allow users to filter data based on specific criteria or conditions, as well as sort data in ascending or descending order. 3. Merging and Appending Data : Users often combine multiple datasets by either merging them based on common columns or appending them vertically to create a single, comprehensive dataset. 4. Adding Custom Columns : Custom columns can be created by applying transformations or calculations to existing columns, enabling users to derive new insights from the data. 5. Aggregating Data : Users can aggregate data by performing operations such as summing, averaging, counting, or finding maximum/minimum values for specific columns. 6. Splitting Columns : This task involves splitting a single column into multiple columns based on a delimiter or a specific pattern, which can be useful for further analysis. 7. Performing Joins : Query Editors allow users to join tables or datasets based on common columns, such as inner joins, left joins, right joins, or full outer joins. 8. Data Type Conversion : Users can convert data types to ensure compatibility or enhance data analysis. Common conversions include converting strings to dates, changing text to numbers, etc. These tasks are fundamental in data preparation and manipulation, allowing analysts and data professionals to transform raw data into valuable insights. If you have any specific questions or need further clarification on any of these tasks, feel free to ask!
