Power Pivot Principles: The A to Z of DAX Functions – CONTAINSSTRINGEXACT
19 July 2022
In our long-established Power Pivot Principles articles, we continue our series on the A to Z of Data Analysis eXpression (DAX) functions. This week, we look at CONTAINSSTRINGEXACT.
The CONTAINSSTRINGEXACT function
Similar to CONTAINSSTRING, this function returns the value TRUE or FALSE, depending upon whether one text string is contained within another. The difference between the two functions is that this one is case sensitive.
The CONTAINSSTRINGEXACT function employs the following syntax to operate:
CONTAINSSTRINGEXACT(within text, find text)
- within text: this is required. This represents the text in which you wish to search for find text
- find text: also required, this represents the text sought.
If find text is indeed a substring of within text and matches case, then TRUE is returned; otherwise, FALSE results.
It should be further noted that:
- CONTAINSSTRINGEXACT is case sensitive.
The following DAX query
"Case 1", CONTAINSSTRINGEXACT("abcd", "bc"),
"Case 2", CONTAINSSTRINGEXACT("abcd", "BC"),
"Case 3", CONTAINSSTRINGEXACT("abcd", "a*d"),
"Case 4", CONTAINSSTRINGEXACT("abcd", "ef")
will provide the following
|Case 1||Case 2||Case 3||Case 4|
