# Dax distinct count group by

2 I have got this following SQL query that gives me the correct value from the database. SELECT SUM ( DISTINCT_ORDER_NUMBERS ) FROM ( SELECT STORE_KEY, **COUNT** ( **DISTINCT** TRANSACTION_NUM ) AS DISTINCT_ORDER_NUMBERS, DATE_KEY, TRANSACTION_TYPE_KEY FROM Pos_Data **GROUP** **BY** STORE_KEY, DATE_KEY, TRANSACTION_TYPE_KEY ) AS A.

COUNTROWS ( **GROUPBY** ( 'Fact Table', 'Office'[Office Name] ) ) This **DAX** measure gives me the same result, this time I am using the **GROUPBY** to use the fact table “Fact Table” and to then use the relationship to **count** the rows for the number of Office Name. As you can see this took 62ms instead of 1,750ms which is roughly 28 times faster.

**DISTINCTCOUNT** function includes the BLANK value. When the function finds no rows to **count**, it returns a BLANK, otherwise it returns the **count** of **distinct** values. Step 1: Now.

In the scenario above I can't **count** the productID in the fact table as it is the surrogate key for the product dimension and the two keys really represent the same product but record the change in product **group**. I want to calculate the **distinct** **count** of the product code column in the product dimension and get the following result:.

We'll use **DISTINCTCOUNT** again, but instead of using the Customer table, we need to find the Customer Name Index inside the Sales table. Once we drag this new measure into the table, you'll see how many.

I assume you're using a measure to caclulate the number of **distinct** reviewers, e.g. # of Reviewers = **DISTINCTCOUNT** ( ProjectData [Reviewer] ) In a table with a Project Name column this gives the number of **distinct** reviewers per project on each row but as you've found, the total is the **distinct** **count** for all projects, not the sum of the column.

The pattern can be extended to compute the **distinct** **count** of any column in a table that can be reached through a many-to-one chain of relationships from the fact tables. This is because SUMMARIZE is able to **group** **by** any of those columns. This pattern is designed for Power BI / Excel 2016-2019. The UNIQUE keyword instructs the database server to return the number of unique non-NULL values in the column or expression. The following example calls the **COUNT** UNIQUE function, but it is equivalent to the preceding example that calls the **COUNT** **DISTINCT** function: SELECT **COUNT** (UNIQUE item_num) FROM items;. Step 1: Find the last known value per State. The first step is to work out the **DAX** expression to determine the last known value for any given TestID by day. Fortunately, **DAX** has a useful function called LASTNOTBLANKVALUE that helps nicely with this. The function uses a reference to a single column of dates (or passed a single-column table.

The **UNIQUE** keyword has the same meaning as the **DISTINCT** keyword in **COUNT** functions. The **UNIQUE** keyword instructs the database server to return the number of **unique** non-NULL values in the column or expression. The following example calls the **COUNT UNIQUE** function, but it is equivalent to the preceding example that calls the **COUNT DISTINCT** function:.

**GROUPBY** - aggregations in data model using **DAX** (**DAX** - Power Pivot, Power BI) This article is about the **GROUPBY** function. It creates **groups** or subtotals in **DAX** (works similarly to Pivot Tables). We will use this table with cars, that can be grouped by various columns. Simple grouping Let´s **group** the table by Brands ( = create a list of brands). The output of the above **dax** expression is. We got unique results perfectly. If you look closely at the **dax** expression, we just provided two parameters. The first parameter is the table name, and the second parameter is the name of the column for which we need unique values. We have talked enough about **dax** summarize function and its uses.
