We can specify columns we want to calculate in two ways:
COUNT(*) will count all rows in all the columns. The result will be taken from the column that has the highest result.
COUNT(FIELD_NAME) that will calculate the row for a particular field (column).
Furthermore, we can use the COUNT function with or without the DISTINCT clause:
COUNT to count all the rows even if there are duplications of data.
COUNT( DISTINCT ...) to calculate unique rows (rows with same values will not be counted). You can visit my site for more details.

If any of the field used in by clause of stats command is null, the whole row is dropped. What type of stats you want to do? I believe you'd need to use fillnull before stats to replace null value with some string e.g. N/A, and then do the stats so that you'd get count for all combinations.
