select current date-1 day 或者 date(current timestamp - 1 days )
VALUES TIMESTAMP('2012-5-25 21:18:12')-1 YEAR-1 MONTH-1 DAY-1 HOUR-1 MINUTE -1 SECOND ;--2011/4/24 20:17:11 复制代码 5、通过days()可以获取两个时间相差天数。 VALUES DAYS(CURRENT DATE)-DAYS(CURRENT DATE-1000 DAY);--1000 6、TO_CHAR()把时间转换成指定格式的字符串类型(db2较低版...
TIMESTAMP ( TIMESTAMP(DEF_TIME)+1 day)+18 HOUR DB2时间函数是我们最常见的函数之一,下面就为您介绍一些DB2时间函数,供您参考,希望可以让您对DB2时间函数有更多的了解。 --获取当前日期: select current date from sysibm.sysdummy1; values current date; ...
1、获取当前日期: select current date from sysibm.sysdummy1; values current date; values current date values current time values current timestamp --ps:sysibm.sysdummy1 表是一个内存的特殊表,常用于访问DB2中的寄存器,从而返回特定需要内容。
SELECT * FROM T WHERE YEAR(DATE) = YEAR(CURREN T DATE) AND MONTH(DATE) = MONTH(CURRENT DATE);如果数据量太大，这个可能有效率问题建议用下面的 SELECT * FROM T WHERE DATE BETWEEN CURRENT DATE - (DAY(CURRENT DATE -1) AND CURRENT DATE;...
时间加减：后边记得跟上时间类型如day、HOUR TIMESTAMP ( TIMESTAMP(DEF_TIME)+1 day)+18 HOUR DB2时间函数是我们最常见的函数之⼀，下⾯就为您介绍⼀些DB2时间函数，供您参考，希望可以让您对DB2时间函数有更多的了解。--获取当前⽇期：select current date from sysibm.sysdummy1;values current date;-...
Example 2:Retrieve all critical errors logged on instance DB2 for database partition 0 in the last day, sorted by most recent. SELECT TIMESTAMP, DBNAME, MSG FROM TABLE (PD_GET_LOG_MSGS(CURRENT_TIMESTAMP - 1 DAYS)) AS T WHERE MSGSEVERITY = 'C' AND INSTANCENAME = 'DB2' AND ...
The calculation is based on either CURRENT TIMESTAMP or CURRENT DATE. You can add or subtract one or more constant values to or from the CURRENT TIMESTAMP or CURRENT DATE value. The expression must not evaluate to a timestamp that occurs after REORG is run. CURRENT TIMESTAMP and CURRENT ...
