How to pivot without aggregation in Snowflake?
In Snowflake, you can pivot data without aggregation by using a combination of the UNPIVOT and PIVOT functions.
Here is an example query that demonstrates how to pivot data without aggregation:
SELECT * FROM ( SELECT col1, col2, col3 FROM table_name ) UNPIVOT ( value FOR column IN (col2, col3) ) PIVOT ( MAX(value) FOR col1 IN ('A', 'B') )
In this query, the UNPIVOT function converts the column values in col2 and col3 into rows, while keeping the values in col1 as columns. Then, the PIVOT function converts the values in col1 into columns, while keeping the values in column as rows.
The MAX aggregation function is used with the PIVOT function to convert multiple rows into a single row with multiple columns. However, since you don’t want any aggregation in your pivot, you can use a function like MIN, MAX, or AVG, which will return the same value for each row.
Note that in this example, the columns to pivot on and the values to aggregate are hard-coded. To make this query more dynamic, you can use dynamic SQL to generate the list of columns to pivot on and the values to aggregate.

Can we use PIVOT without aggregate function in Snowflake?
In Snowflake, the PIVOT function requires an aggregate function to be specified. This is because the PIVOT function is designed to transform rows into columns based on a defined set of values, and in the process, the data must be aggregated.
However, if you need to pivot data without using an aggregate function in Snowflake, you can use the TRANSPOSE function instead. The TRANSPOSE function can transform columns into rows or rows into columns without the need for aggregation.
Here’s an example of using the TRANSPOSE function to pivot data in Snowflake:
SELECT * FROM ( SELECT id, col1, col2, col3 FROM my_table ) AS t TRANSPOSE(col1, col2, col3) AS pivoted_data
In this example, the TRANSPOSE function is used to pivot the columns col1, col2, and col3 into rows. No aggregate function is used because the TRANSPOSE function does not require aggregation.
Can PIVOT be used without aggregate function?
No, the PIVOT operation in SQL always requires an aggregate function to be used.
The PIVOT operation in SQL is used to transform rows into columns, based on a specified set of values. When using the PIVOT operation, you need to provide an aggregate function that will be used to aggregate the data in the pivot columns.
For example, suppose you have a table that contains sales data, with columns for salesperson, product, and sales amount. You might want to pivot this table so that you have columns for each salesperson and rows for each product, with the sales amount for each product and salesperson combination displayed in the corresponding cell. To do this, you would need to use an aggregate function (such as SUM, COUNT, AVG, etc.) to aggregate the sales amounts for each combination of salesperson and product.
In summary, the PIVOT operation in SQL always requires an aggregate function to be used, as it is used to aggregate data across columns that have been pivoted from rows.
Can pivot tables only be used with aggregated queries?
Yes, pivot tables are typically used with aggregated queries. Pivot tables are a powerful tool in data analysis that allows you to summarize and analyze large datasets by grouping and aggregating data based on certain criteria. The results are presented in a table format that can be easily manipulated and visualized.
The purpose of pivot tables is to summarize large amounts of data, often by grouping data based on specific criteria and applying aggregate functions such as SUM, COUNT, AVERAGE, MAX, MIN, etc. These functions are used to summarize the data within each group.
However, pivot tables can also be used with non-aggregated queries, but they may not be as useful in such cases. In non-aggregated queries, pivot tables can still be used to organize and display data in a meaningful way, but the aggregated functions won’t be available or useful. Instead, pivot tables can be used to group data by different categories and display them in a more organized and readable format.
