mysql5.5表分区问题
1.字段属性为timestamp,在分区时出现异常
constant, random or timezone-dependent expressions in (sub)partitioning function are not allowed
网上找了下好像是说timestamp类型分区时不起作用要改成datetime or date
pruning is not expected to work for tables partitioned on a timestamp column, and you should use a datetime or date column for this instead.
2.修改为datetime后出现错误提示如下
a primary key must include all columns in the table's partitioning function
mysql分区字段必须包含在主键中
sql如下：
alter table test partition by list (dayofweek(time)) ( partition p01 values in (1), partition p02 values in (2), partition p03 values in (3), partition p04 values in (4), partition p05 values in (5), partition p06 values in (6), partition p07 values in (7), partition perr values in (0));
