Question
You are sorting data in a table in SELECT statement in descending order. The column you are sorting on contains NULL records, where will the NULL record appears?
Solution
When you sort data in a table in a SELECT statement in descending order, the NULL records will appear at the end of the sorted data. This is because, in SQL, NULL is considered to be the lowest possible value. Therefore, when sorting in descending order, NULL values will be treated as the lowest values and will appear last.
