SELECT clause in Google Sheets - Dashboard Guide

Dashboard Mode - SELECT clause

Dashboard Goal

Show a list of products and their sales amounts using the SELECT clause in the QUERY function.

Sample Data

Product	Category	Sales	Region
Apples	Fruit	100	East
Bananas	Fruit	150	West
Carrots	Vegetable	200	East
Dates	Fruit	120	South
Eggplants	Vegetable	180	West

Dashboard Components

• Product Sales Table: Shows product names and sales amounts.
  Formula: =QUERY(A1:D6, "SELECT Col1, Col3", 1)
  Explanation: Selects columns A (Product) and C (Sales) from the data including headers.
• Total Sales: Shows total sales amount.
  Formula: =SUM(C2:C6)
  Explanation: Adds all sales values from the Sales column.

Dashboard Layout

+---------------------+-----------------+
| Product Sales Table  |  Total Sales    |
| (SELECT Col1, Col3) |  (SUM C2:C6)    |
+---------------------+-----------------+

Interactivity

Adding a filter for Category or Region will update the Product Sales Table and Total Sales to show only matching rows.

Self Check

If you add a filter to show only Category = 'Fruit', which products appear in the Product Sales Table and what is the new Total Sales?

Key Result

Dashboard shows product sales using QUERY's SELECT clause and total sales sum.

Practice

1. What does the SELECT clause do inside the QUERY function in Google Sheets?

easy

A. It adds new columns to the data.

B. It sorts the data in ascending order.

C. It filters rows based on a condition.

D. It chooses which columns to show from the data.

Solution

1. Step 1: Understand the role of SELECT in QUERY

   The SELECT clause specifies which columns to display from the data range.

2. Step 2: Differentiate from other clauses

   Sorting is done by ORDER BY, filtering by WHERE, and adding columns is not done by SELECT.

3. Final Answer:

   It chooses which columns to show from the data. -> Option D

4. Quick Check:

   SELECT = choose columns [OK]

Hint: SELECT picks columns to show, not rows or sorting [OK]

Common Mistakes:

• Confusing SELECT with WHERE clause
• Thinking SELECT sorts data
• Assuming SELECT adds new columns

2. Which of the following is the correct syntax to select columns A and C using the QUERY function?

easy

A. =QUERY(A1:C10, "SELECT B, D")

B. =QUERY(A1:C10, "SELECT 1, 3")

C. =QUERY(A1:C10, "SELECT A, C")

D. =QUERY(A1:C10, "SELECT A C")

Solution

1. Step 1: Check correct column letters in SELECT

   Columns are referenced by letters like A, B, C. To select columns A and C, use "SELECT A, C" with a comma.

2. Step 2: Verify syntax correctness

   =QUERY(A1:C10, "SELECT A, C") uses correct syntax with comma and column letters. =QUERY(A1:C10, "SELECT 1, 3") uses numbers which is invalid. =QUERY(A1:C10, "SELECT B, D") uses B and D which are wrong columns. =QUERY(A1:C10, "SELECT A C") misses comma between columns.

3. Final Answer:

   =QUERY(A1:C10, "SELECT A, C") -> Option C

4. Quick Check:

   Use column letters with commas in SELECT [OK]

Hint: Use column letters with commas in SELECT clause [OK]

Common Mistakes:

• Using numbers instead of letters for columns
• Omitting commas between columns
• Selecting columns not in the data range

3. Given the data in A1:C4 as:

A | B | C
1 | 2 | 3
4 | 5 | 6
7 | 8 | 9

What will be the output of =QUERY(A1:C4, "SELECT B, C")?

medium

A. 2 3
5 6
8 9

B. B C
2 3
5 6
8 9

C. A B
1 2
4 5
7 8

D. 1 2
4 5
7 8

Solution

1. Step 1: Identify columns B and C data

   Column B values are 2, 5, 8 and column C values are 3, 6, 9 from rows 2 to 4.

2. Step 2: Understand QUERY output format

   QUERY includes headers by default, so output shows header row "B C" followed by data rows.

3. Final Answer:

   B C 2 3 5 6 8 9 -> Option B

4. Quick Check:

   QUERY shows headers and selected columns [OK]

Hint: QUERY outputs headers by default with selected columns [OK]

Common Mistakes:

• Ignoring headers in output
• Selecting wrong columns
• Mixing up row and column data

4. The formula =QUERY(A1:C10, "SELECT A B") returns an error. What is the fix?

medium

A. Add a comma between A and B: "SELECT A, B"

B. Change A and B to numbers: "SELECT 1 2"

C. Remove the SELECT keyword

D. Use lowercase letters: "select a b"

Solution

1. Step 1: Identify syntax error in SELECT clause

   The columns A and B must be separated by a comma in the SELECT clause.

2. Step 2: Correct the syntax

   Adding a comma between A and B fixes the syntax: "SELECT A, B".

3. Final Answer:

   Add a comma between A and B: "SELECT A, B" -> Option A

4. Quick Check:

   Columns must be comma-separated in SELECT [OK]

Hint: Separate columns with commas in SELECT clause [OK]

Common Mistakes:

• Omitting commas between columns
• Using numbers instead of letters
• Removing SELECT keyword

5. You have a table with columns Date (A), Product (B), and Sales (C). You want to use QUERY to show only the Product and Sales columns but sorted by Sales descending. Which formula correctly uses SELECT and ORDER BY?

hard

A. =QUERY(A1:C100, "SELECT B, C ORDER BY C DESC")

B. =QUERY(A1:C100, "SELECT A, B ORDER BY C DESC")

C. =QUERY(A1:C100, "SELECT B, C ORDER BY B DESC")

D. =QUERY(A1:C100, "SELECT B, C ORDER BY A DESC")

Solution

1. Step 1: Identify columns to select

   You want to show Product (B) and Sales (C), so SELECT B, C is correct.

2. Step 2: Sort by Sales descending

   ORDER BY C DESC sorts by Sales column descending.

3. Step 3: Verify full formula correctness

   =QUERY(A1:C100, "SELECT B, C ORDER BY C DESC") correctly combines SELECT and ORDER BY clauses. Other options select wrong columns or order by wrong columns.

4. Final Answer:

   =QUERY(A1:C100, "SELECT B, C ORDER BY C DESC") -> Option A

5. Quick Check:

   SELECT columns + ORDER BY sales DESC = correct [OK]

Hint: Use SELECT for columns, ORDER BY for sorting in QUERY [OK]

Common Mistakes:

• Ordering by wrong column
• Selecting wrong columns
• Missing ORDER BY clause
