如果您的数据在其他表中已经存在,可以通过INSERT SELECT FROM
将数据复制到另外一张表。
语法
INSERT INTO table_name
[( column_name [, …] )]
query;
参数
column_name
:列名,如果需要将源表中的部分列数据插入到目标表中,SELECT子句中的列必须与INSERT子句中列的顺序、数据类型一致。query
:可以是SELECT FROM TABLE
或者SELECT FROM VIEW
。
示例
以指定列名的方式,从CUSTOMER表中复制某几列数据到NEW_CUSTOMER表中。
INSERT INTO new_customer (customer_id, customer_name, phone_num) SELECT customer_id, customer_name, phone_num FROM customer WHERE customer.customer_name = '杨过';
不指定列名,从CUSTOMER表中复制所有列数据到NEW_CUSTOMER表中。
INSERT INTO new_customer SELECT customer_id,customer_name,phone_num,city_name,sex,id_number,home_address,office_address,age,login_time FROM customer WHERE customer.customer_name = '杨过';
