P132

insert into customers VALUES(NULL,'Pep E.Lapew','100 Main Street',,Los Angeles','CA','90046','USA',NULL,NULL); #customers表中刚好有9个维度（一定要对应上），9个值会对应这9个维度，维度的次序由表定义#

insert into customers （cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country,cust_contact,cust_email) VALUES(NULL,'Pep E.Lapew','100 Main Street',,Los Angeles','CA','90046','USA',NULL,NULL); #把维度列出来，按这个顺序对应后面的值填充到新行#

跑出来对应的结果是这样：

insert into customers（cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country) VALUES('Pep E.Lapew','100 Main Street',‘Los Angeles','CA','90046','USA')

insert into customers（cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country) VALUES('Pep E.Lapew1','100 Main Street1',’Los Angeles1','CA1','90045','USA1');  #同时增加两行，维度和值一一对应#  #是的我没运行出来，不知道是不是版本的问题，还是语句出错了）

insert into customers（cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country) VALUES('Pep E.Lapew','100 Main Street',‘Los Angeles','CA','90046','USA')

,('Pep E.Lapewo','100 Main Streeto',’Los Angeleso','CAo','90045','USA');     #和上面表达的意思是一样#

insert into customers（cust_id,cust_contact,cust_emails,cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country)

select  cust_id,cust_contact,cust_emails,cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country from custnew;

#在custnew里面对应的这些列的数据导入到表customers中，注意这个语句没有了values(‘ ’) #
