CONTAINSTRING DAX

Exploring the CONTAINSSTRING Function in DAX

Understanding the CONTAINSSTRING Function

At its core, the CONTAINSSTRING function enables users to determine whether a specific substring exists within a given text string. This function returns a Boolean value, TRUE if the substring is found, and FALSE if it is not.

Here's the basic syntax of the CONTAINSSTRING function:

CONTAINSSTRING(<text>, <substring>)

<text>: The text string within which you want to search.

<substring>: The substring you're searching for within the text.

Practical Example: Using CONTAINSSTRING in DAX

Let's delve into a practical example to grasp how the CONTAINSSTRING function works within the context of DAX. Suppose we have a dataset containing product information, including a column named ProductName. We're interested in identifying which product names contain the word "apple".

We can achieve this by creating a calculated column using the CONTAINSSTRING function:

ContainsApple = 

IF(

    CONTAINSSTRING(Products[ProductName], "apple"),

    "Yes",

    "No"

)

In the above DAX expression:

We utilize the CONTAINSSTRING function to search for the substring "apple" within the ProductName column.

If the substring is found within the ProductName, the function returns TRUE, and the calculated column ContainsApple will display "Yes".

If the substring is not found, the function returns FALSE, and the calculated column Contains Apple will display "No".

Conclusion

The CONTAINSSTRING function in DAX is a valuable tool for identifying specific patterns within text strings, facilitating data analysis and decision-making processes. Whether it's filtering data, creating calculated columns, or defining measures based on text patterns, understanding and leveraging the CONTAINSSTRING function empowers analysts and data professionals to extract actionable insights from their datasets.

Incorporate CONTAINSSTRING into your DAX toolkit and unlock new avenues for data exploration and analysis in your projects.

Calculate Sales for Last Year Month to date

Sameperiodlastyear till to date based on selection in year and month selection Problem:  If the current year and month are selected, sales data from the same period of the previous year up to the current date is needed. For instance, if it's March 2024, you'd require sales data from March 2023 up to today's date. If the selection is for a different year and month, such as January 2023, you need the entire sales data for January 2022. Solution:  For this scenario you need to create Three Dax Measures Measure 1 = (This measure is to calculate current month sales till the date) CALCULATE( SUM(CST[Total Financed Amount]), SAMEPERIODLASTYEAR( DATESYTD('Calendar Table'[Date]) ), FILTER( ALL('Calendar Table'), 'Calendar Table'[MonthNum] = MONTH(NOW()) && DAY('Calendar Table'[Date]) <= DAY(NOW()) ) ) Explanation: CALCULATE : This is a DAX function used to modify or filter the context for a calculation. It can apply additional filters to a ...
