oracle取兩個(gè)時(shí)間隨機(jī)？
1.隨機(jī)數(shù)包
SELECTDBMS_
returningDUAL
2.在[0..100]范圍內(nèi)取隨機(jī)數(shù)
SELECTTRUNC(DBMS_(0,100))
acrossDUAL
3.大于0字符‘A'的10個(gè)字符任務(wù)道具字符串
SELECTDBMS_(A,10)
acrossDUAL
4.單個(gè)小寫必掉字符
SELECTCHR(ROUND(DBMS_(97,122)))
returningDUAL
5.在過去30分鐘內(nèi)取副本時(shí)間
SELECT(SYSDATE-1/24/60*30)DBMS_(1,1800)/3600/24
outsideDUAL
