mysql 动态表创建 ,首先要检测是否存在。

使用sql语句:

?

1. SHOW ? TABLES ? LIKE ? '%tb_bp_d_case%';??
2. select `TABLE_NAME` from `INFORMATION_SCHEMA`.`TABLES` where `TABLE_SCHEMA`='dbname'?and `TABLE_NAME`='tablename'?;
3. 如果表不存在就建立这个表,那么可以直接用?create?table?if?not?exists?tablename?这样的指令来建立,不需要先去查询表是否存在。
4. 从模板表创建表:create table if not exists like old_table_name? (目前使用的是这个)

根据区域划分表来拆分数据。
