Dynamic Column Reference in Google Sheets Query: A Powerful Technique

Do you ever find yourself needing to dynamically control the columns in your Google Sheets Query? If so, you’re in luck! In this article, I’ll teach you how to easily achieve dynamic column reference in your Query formula. Trust me, it’s easier than you think!

Understanding Dynamic Column Reference in Google Sheets Query

Before we dive into the technical details, let me explain what dynamic column reference means in the context of a Google Sheets Query. Essentially, it allows you to select specific columns based on certain criteria or conditions.

Let’s say you have a dataset with 50 columns. Instead of returning all the columns at once or manually changing the data range every time, dynamic column reference lets you select columns based on their numbers. For example, you can return columns 10 to 20 or 5 to 45 without breaking a sweat.

How to Get Dynamic Column Identifiers in Select Clause in Query

Now that you understand the concept, let’s move on to the implementation. To achieve dynamic column reference in your Query formula, follow these steps:

1. Open your Google Sheets and navigate to the worksheet where your data is located.
2. Identify the starting and ending column numbers you want to include in your Query. For instance, let’s say you want to select columns 5 to 10.
3. In an empty cell, enter the starting column number (in this case, 5) and label it as C9. Similarly, enter the ending column number (10) and label it as F9.

That’s the preliminary setup! Now, let’s create the formula that generates the dynamic column reference.

Formula That Generates Dynamic Column in Google Sheets Query

To create a dynamic column reference in your Query formula, use the following master formula:

=QUERY({A1:M5},"Select "&ArrayFormula(textjoin(", ",TRUE,("Col"&row(indirect("A"&C9&":A"&F9))))))

This formula dynamically generates the column identifiers based on the values in cells C9 and F9. For example, if the values in those cells are 5 and 10 respectively, the formula will return the Query formula: Select Col5, Col6, Col7, Col8, Col9, Col10.

Feel free to experiment with different starting and ending column numbers to get your desired results. Simply update the values in cells C9 and F9, and the formula will automatically adjust the dynamic column reference accordingly.

Utilizing the Dynamic Query Formula in Your Own Data Range

Now that you have your dynamic Query formula ready, you can easily apply it to your own data range. Here’s what you need to do:

1. Copy the formula mentioned above.
2. Replace the data range A1:M5 in the formula with your own data range.
3. Update the cell references C9 and F9 to match the cells where you’ve entered your starting and ending column numbers.

Remember, if you’re using an infinite data range like A1:M, make sure to move the control cells C9 and F9 outside of that range to avoid any conflicts.

Sticky First Column in Query with Dynamic Column Control

If you want to make the first column in your Query sticky while still dynamically controlling the month columns, here’s how you can modify the formula:

={index(A1:A7),QUERY({B1:M7},"Select "&ArrayFormula(textjoin(", ",TRUE,("Col"&row(indirect("A"&C9&":A"&F9))))))}

By using this modified formula, the first column will remain fixed while the rest of the columns are dynamically selected based on your criteria.

How the Formula Generates Dynamic Column References in Query (Tips for those who want to learn the logic)

If you’re curious about how the formula works behind the scenes, let me break it down for you.

To generate the dynamic column references, we primarily rely on the ROW function and the INDIRECT function. Here’s the step-by-step logic:

1. Assume C9 and F9 are the cells that control our dynamic column numbers.
2. Use the ROW function to generate a range of numbers from C9 to F9. For example, if C9 contains 3 and F9 contains 10, the formula ArrayFormula(row(A3:A9)) will return the numbers 3 to 10 in a row-wise format.
3. To incorporate the “Col” prefix for each number, modify the formula to ArrayFormula(row(indirect("A"&C9&":A"&F9))).
4. Finally, combine all the column identifiers using the TEXTJOIN function, separating each identifier with a comma.

That’s the basic logic that enables the formula to dynamically generate column references in your Query.

Conclusion

Congratulations! You’ve just learned how to achieve dynamic column reference in Google Sheets Query. This powerful technique allows you to easily select specific columns based on your criteria without any manual adjustments.
