如何将数据插入具有自动递增主键的 MySQL?
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'
);
