How to query data from timestamp column with delay.?
我想要一个查询从 derby table 中获取数据,其中时间值距当前时间不到两小时的时间戳。以下查询给出错误
operator with a left operand type of 'TIMESTAMP' and a right operand type of 'INTEGER' is not supported.
查询:
select * from NEWS WHERE NEWS_DATE < current_timestamp-2
感谢任何帮助
答案在这里,
select *from NEWS where {fn TIMESTAMPDIFF( SQL_TSI_MINUTE, NEWS_DATE,current_timestamp)} <120
