you are sorting a table using "order by"(descending) clause of
a column which contains a null value...whether that row
containing null value will come first or last in the output??

Answer Posted / suman rana

if you are sorting a table using "order by"(descending)
clause of a column which contains a null value, row
containing null value will come first. Alternatively you can
use the clause "Nulls First" along with order by clause to
appear the Null values first.
