Visual calculation
Returns the starting position of one text string within another text string. FIND is case-sensitive.
Syntax
FIND(<find_text>, <within_text>[, [<start_num>][, <NotFoundValue>]])
Parameters
| Term | Definition |
|---|---|
| find_text | The text you want to find. Use double quotes (empty text) to match the first character in within_text. |
| within_text | The text containing the text you want to find. |
| start_num | (optional) The character at which to start the search; if omitted, start_num = 1. The first character in within_text is character number 1. |
| NotFoundValue | (optional, but strongly recommended) The value that should be returned when the operation does not find a matching substring, typically 0, -1, or BLANK(). If not specified, an error is returned. |
Return value
Number that shows the starting point of the text string you want to find.
Remarks
Whereas Microsoft Excel has multiple versions of the FIND function to accommodate single-byte character set (SBCS) and double-byte character set (DBCS) languages, DAX uses Unicode and counts each character the same way; therefore, you do not need to use a different version depending on the character type.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
FIND does not support wildcards. To use wildcards, use SEARCH.
Example
The following DAX query finds the position of the first letter of "Bike", in the string that contains the reseller name. If not found, Blank is returned.
Keep in mind, FIND is case-sensitive. In this example, if "bike" were used in the <find_text> argument, no results would be returned. Use SEARCH for case-insensitive.
