如何将数据插入具有自动递增主键的 MySQL?

问题描述

我已经创建了一个带有主键的表并启用了 AUTO_INCREMENT，我如何让 MYSQL 使用 AUTO_INCREMENT?

I've created a table with a primary key and enabled AUTO_INCREMENT, how do I get MYSQL use AUTO_INCREMENT?

CREATE TABLE IF NOT EXISTS test.authors (
    hostcheck_id INT PRIMARY KEY AUTO_INCREMENT,
    instance_id INT,
    host_object_id INT,
    check_type INT,
    is_raw_check INT,
    current_check_attempt INT,
    max_check_attempts INT,
    state INT,
    state_type INT,
    start_time datetime,
    start_time_usec INT,
    end_time datetime,
    end_time_usec INT,
    command_object_id INT,
    command_args VARCHAR(25),
    command_line VARCHAR(100),
    timeout int,
    early_timeout INT,
    execution_time DEC(18,5),
    latency DEC(18,3),
    return_code INT,
    output VARCHAR(50),
    long_output VARCHAR(50),
    perfdata VARCHAR(50)
);

这是我使用的查询，我已经尝试了 "" 和 "1" 作为第一个值，但它不起作用.

Here is the query I used, I've tried "" and "1" for the first value but it doesn't work.

INSERT INTO  test.authors VALUES ('1','1','67','0','0','1','10','0','1',
'2012-01-03 12:50:49','108929','2012-01-03 12:50:59','198963','21','',
'/usr/local/nagios/libexec/check_ping  5','30','0','4.04159','0.102','1',
'PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms','',
'rta=2.860000m=0%;80;100;0'); 

推荐答案

为了利用列的自动递增功能，插入行时不要为该列提供值.数据库将为您提供一个值.

In order to take advantage of the auto-incrementing capability of the column, do not supply a value for that column when inserting rows. The database will supply a value for you.

INSERT INTO test.authors (
   instance_id,host_object_id,check_type,is_raw_check,
   current_check_attempt,max_check_attempts,state,state_type,
   start_time,start_time_usec,end_time,end_time_usec,command_object_id,
   command_args,command_line,timeout,early_timeout,execution_time,
   latency,return_code,output,long_output,perfdata
) VALUES (
   '1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
   '2012-01-03 12:50:59','198963','21','',
   '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
   '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
   '','rta=2.860000m=0%;80;100;0'
);
