SQL LAST() Function

LAST() 함수

LAST() 함수는 선택된 컬럼의 마지막 값을 반환합니다.

SELECT LAST(column_name) FROM table_name;

Note: LAST() 함수는 MS Access에서 지원됩니다.

SELECT TOP 1 column_name FROM table_name
ORDER BY column_name DESC;

SELECT TOP 1 CustomerName FROM Customers
ORDER BY CustomerID DESC;

SELECT column_name FROM table_name
ORDER BY column_name DESC
LIMIT 1;

SELECT CustomerName FROM Customers
ORDER BY CustomerID DESC
LIMIT 1;

SELECT column_name FROM table_name
ORDER BY column_name DESC
WHERE ROWNUM <=1;

SELECT CustomerName FROM Customers
ORDER BY CustomerID DESC
WHERE ROWNUM <=1;

이 튜토리얼에서 우리는 잘 알려진 Northwind 예제 데이터베이스를 사용합니다.

아래에서 선택이다 "Customers" 표 :

CustomerID	CustomerName	ContactName	Address	City	PostalCode	Country
