Query: lastvaluefrom no elements in sequence
In this query, we are trying to find the last value from a sequence that contains no elements.
Explanation:
When the sequence has no elements, it means there is nothing to select the last value from. Thus, the query will return an empty or null result.
Example:
SELECT LAST_VALUE(column_name) OVER () AS LastValue
FROM table_name
WHERE condition;
In the example above, we are trying to find the last value from a specific column in a table based on a certain condition. However, if the condition does not match any rows and there are no elements in the sequence, the query will return an empty or null result.
