1.mysql5.5增加关键字columns
作用:
2.对一个不是分区表的数据库表追加分区方法:
?
ALTER TABLE test_load_888_20110428 PARTITION BY RANGE COLUMNS(datatime)( PARTITION p1 VALUES LESS THAN ('2011-12-06 00:00:00'), PARTITION p0 VALUES LESS THAN (maxvalue) )
?删除分区:
?
ALTER TABLE test_load_888_20110428 DROP PARTITION p0;
?添加分区:
ALTER TABLE test_load_888_20110428 ADD PARTITION ( PARTITION p0 VALUES LESS THAN (maxvalue) )
?第二种方式:
ALTER TABLE test_load_bus_20110428 REORGANIZE PARTITION p0 INTO ( PARTITION p2 VALUES LESS THAN ('2011-12-07 00:00:00'), PARTITION p0 VALUES LESS THAN (maxvalue) );
