Wildcard characters in filter expression

[giovissimo]

Hello,

I have a table including all the students enrolled in a university course, and need to obtain the number of those who attended certain schools (identified by the prefix "school").

To do so, all I need is to FILTER the "SchoolName" field inside a CALCULATE expression, in order to count only those values starting with the word "school", adding an asterisk as a wild character after the word "school". 

Therefore I wrote the following:

Students = CALCULATE([Students], FILTER(ALL(Course[SchoolName]),Course[SchoolName]="School*"))

but I get a null value.

What's wrong with my expression ?

@giovissimo there is no concept of wildcard, you can do something like this

Students = CALCULATE([Students], FILTER(ALL(Course[SchoolName]),LEFT(Course[SchoolName],5)="School"))

Students = CALCULATE([Students], FILTER(ALL(Course[SchoolName]),CONTAINSSTRING(Course[SchoolName],"School"))
