Rather than the text being all capital letters as entered in the table, only the first letter is capitalized. Step 1: Get the desired date you want to convert into 'yyy-MM-dd' format. So, I created a string variable named "current_date" and gave it a value using the expression : formatDatetimeValue(utcNow(), 'yyyy-MM-dd') Step 2: Data models support the unary operator, - (negative), but this operator doesn't change the data type of the operand. Each of these products use different names for certain data types. This is important.

DAX. is a value or expression that evaluates to a single value. Why are physically impossible and logically impossible concepts considered separate in terms of probability? The only change that we need to make in the code that we have written so far is that instead of specifiying an explicit string in the CurrentText variable we are going to let the row context do the Job, so instead of writing. So it's important and useful to use the correct data types for columns. Since we only need the first two digits for the year column, enter '2' in the Count tab and click OK. Now, let's modify our new column by editing the Formula Bar. Remarks The function returns an error when a value cannot be converted to the specified data type.
