Let’s get started:
Import below sample dataset into Power BI desktop-
|4||Value for money||5|
|7||Help 24 * 7||8|
|8||AC / Lights||8|
|9||Help – Desk||10|
Now follow these steps-
Step-1: Add one new column , Right click on dataset and select “New Column” and write below DAX function.
Search char position = SEARCH("R",Survey[Statement], , -1)
Step-2: Here we want to find “R” character position for all values of Statement column.
Now click on Data tab and you can see the position number. It will return -1, if not found character in string.
Step-3: Support wildcard character, only for question mark(?) & asterisk (*) use tilde (~) before the character.
Step-4: For other wildcard character- no need to use tilde (~) before the character.
