db2有什么方法可以将毫秒数转化成timestamp时间类型
各位大神，请教一下，db2有什么方法可以将毫秒数转化成timestamp时间类型。在oracle中可以这样来实现SELECT TO_CHAR(operationtime / (1000 * 60 * 60 * 24) + TO_DATE('1970-01-01 08:00:00', 'YYYY-MM-DD HH24:MI:SS'), 'YYYY-MM-DD HH24:MI:SS') AS CDATE FROM table 。...显示全部

我這個方法有點複雜，你看下吧
SELECT VARCHAR_FORMAT((TIMESTAMP ('1970-01-01-08.00.00.00000')
+ (operationtime/86400000) DAYS
+ (MOD(operationtime,86400000)/3600000) HOURS
+ (MOD(MOD(operationtime,86400000),3600000)/60000) MINUTES
+ (MOD(MOD(MOD(operationtime,86400000),3600000),60000)/1000)SECONDS
+ (MOD(MOD(MOD(MOD(operationtime,86400000),3600000),60000),1000) * 100) MICROSECONDS)
,'YYYY-MM-DD HH24:MI:SS') FROM SYSIBM.SYSDUMMY1;
