从rownum（）= 3的表中删除

Question

如何使用“ rownum”从任何表中删除第三行（我正在使用hsqldb） 我尝试许多查询，结果返回始终为0 例如这个->

SELECT ROW_NUMBER FROM

(SELECT ROWNUM() AS ROW_NUMBER, abs.* FROM absence abs)

WHERE ROW_NUMBER = 3;

Answer 1

您需要在DELETE语句的子查询中找到第三行。

例如

DELETE FROM customer WHERE id IN (SELECT id FROM customer ORDER BY id OFFSET 2 FETCH 1 ROW ONLY)
