LEAD
适用于 ✅ 开源版 ✅ 专业版 ✅ 企业版
LEAD 窗口函数允许获取在下一行评估的表达式的值，或者如果给定偏移量，则获取第 n 个下一行的值。
SELECT ID, lead(ID) OVER (ORDER BY ID), lead(ID, 2) OVER (ORDER BY ID), lead(ID, 2, -1) OVER (ORDER BY ID) FROM BOOK;
create.select(
BOOK.ID,
lead(BOOK.ID).over(orderBy(BOOK.ID)),
lead(BOOK.ID, 2).over(orderBy(BOOK.ID)),
lead(BOOK.ID, 2, -1).over(orderBy(BOOK.ID)))
.from(BOOK)
.fetch();
产生
+----+------+------+------+ | id | lead | lead | lead | +----+------+------+------+ | 1 | 2 | 3 | 3 | | 2 | 3 | 4 | 4 | | 3 | 4 | | -1 | | 4 | | | -1 | +----+------+------+------+
lead(BOOK.ID).over(orderBy(BOOK.ID))
