一、分区表基本操作 1、按时间分区表创建：create table t_test ( pk_id number(30) not null, add_date_time DATE, constraintPK_T_TEST primary key (pk_id))PARTITION BY RANGE (add_date_time)( PARTITIONt_test_2013_less VALUES LESS THAN (TO_DATE(‘2013-01-01 00:00:00‘,‘...
oracle 有个日期字段想按月分区 代码:partition by range 这样不行,你想用范围分区,但是你这个写法意思是列表分区by list建议用范围分区,但是用logtime就行了,本身就是日期格式,本来就可以做比较
在实际运用Range分区时,遇到了这样的难题: createtableTMP_LXQ_1 ( PROPOSALNO VARCHAR2(22), STARTDATE DATE ) partitionbyrange(STARTDATE) ( partitionpart_t01values less than(to_date('2008-01-01','yyyy-mm-dd')) , partitionpart_t02values less than(to_date('2009-01-01','yyyy-mm-dd')) ...
