Verify Primary Key in Incorta

I’m not sure what is the primary key of a table, for example, this Orderitems table. Here is how I verified. My assumption is that an order can have multiple items and an item will be listed once an order.



By grouping Orderitems with orderNumber and productCode, we should get one row per group. If we got more than one row, we can conclude that the combination of orderNumber and productCode is not unique.

The result shows that no data returned. This verifies my assumption is true.

To get the fiscal week end date, first I get the fiscal week of the year floor((doy-1)/7) , and get the current number of days from the last day of the week through (((floor((doy-1)/7))+1)*7)-doy , then returns the week end date that is the num days after the date date_add(date, num_...

How to create histogram in Incorta use bin function.

Image
The  Ecommerce_Customer schema has four variables, Time On App, Time On Website, Length Of Membership, and Yearly Amount Spent. I want to see the distribution of these data. Incorta let me preview the data and show max and min data of each using its Preview function. Here are the steps I used to create a histogram in Incorta. First,  I used the bin function in Incorta divided into different levels. Here is the documentation for the bin function.        https://docs.incorta.com/4.5/r-bin Here is the result of the bin function. I divided the average of session length into 6 levels. If the length is less than 30, it will be labeled as 'SLV1', and if the length is greater than 30 but less than 32, it will be labeled as 'SLV2', by basically, according to the min and max value. I see the minimum value is close to 30, and the maximum value close to 38. I decided to use 2 minutes as the interval and created the formula using the bin function. I'm grouping...
