Could you please set an example for your job requirement? What does your expected result look like?

I want to create a user defined indicator for computing standard deviation of a numerical column. Can you please help me with the indicator category to choose? I want to use MySQL query "select stddev(col_name) from table_name" which will return just one value. I tried multiple times without success. Thanks!
