MySql 存储过程 : Get Last Inserted Id

Question

我的程序:

DELIMITER $$

CREATE PROCEDURE `******`.`*********************` 
(   IN customerName varchar(100),IN customerEmail varchar(100),IN address1 varchar(100),IN address2 varchar(100),
    IN zip int,IN city varchar(100),IN state varchar(100),IN country varchar(100),IN region varchar(100),OUT customerId int)
BEGIN

Declare custId int default 0;
Declare zipExist int default 0;

Select Count(*) into zipExist from *****.********** where Zip_Code = zip;

if zipExist = 0 then
Insert into *****.**********(Zip_Code,City,State,Country,Region) values(zip,city,state,country,region); 
end if;

Insert into *****.**********(Address_1,Address_2,ZIP_Code) values(address1,address2,zip);

SET custId = LAST_INSERT_ID();

if custId > 0 then
Insert into *****.**********(Customer_Name,Customer_Email,Address) values(customerName,customerEmail,custId);
end if;

SET customerId = LAST_INSERT_ID();
END $$

在调用过程时出现此错误:错误代码:1062。键“PRIMARY”的重复条目“1”

我假设 custId= Last_Insert_Id(); 这一行给我错误的插入 ID。因此它无法插入到最后一张表中。我想知道插入后如何获取最后插入的ID。(Address_id 是自动递增的)。

表格是:

客户:
CustomerId int 自增,
客户名称 varchar,
客户邮箱 varchar,
AddressId int fk 引用 address.AddressId

地址:

AddressId pk int 自增,
地址 1 varchar,
地址 2 varchar,
zip int fk 引用 zipmaster.zip

压缩大师:

zip int pk自增，
城市变量，
状态变量，
国家/地区 varchar

LAST_INSERT_ID() returns only automatically generated AUTO_INCREMENT values, if the customer_id is not auto-increment you will not get the correct value.
