MySQL判断表是否存在

 

有四种方式进行判断:

 

1. SHOW TABLES LIKE '%tb_bp_d_case%';2. select TABLE_NAME from INFORMATION_SCHEMA.TABLES where TABLE_SCHEMA='dbname' and TABLE_NAME='tablename' ;
Copy after login

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;
Copy after login
