在webform
表中插入唯一ID时,我将其插入本地服务器,但在实时服务器上,它为“密钥1”提供了“重复条目'0”错误。
本地服务器上的Webform表结构:
CREATE TABLE `webform` (
`nid` int(10) unsigned NOT NULL,
`confirmation` text NOT NULL,
`confirmation_format` tinyint(4) NOT NULL DEFAULT '0',
`redirect_url` varchar(255) DEFAULT '<confirmation>',
`status` tinyint(4) NOT NULL DEFAULT '1',
`block` tinyint(4) NOT NULL DEFAULT '0',
`teaser` tinyint(4) NOT NULL DEFAULT '0',
`allow_draft` tinyint(4) NOT NULL DEFAULT '0',
`auto_save` tinyint(4) NOT NULL DEFAULT '0',
`submit_notice` tinyint(4) NOT NULL DEFAULT '1',
`submit_text` varchar(255) DEFAULT NULL,
`submit_limit` tinyint(4) NOT NULL DEFAULT '-1',
`submit_interval` int(11) NOT NULL DEFAULT '-1',
`total_submit_limit` int(11) NOT NULL DEFAULT '-1',
`total_submit_interval` int(11) NOT NULL DEFAULT '-1',
PRIMARY KEY (`nid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
实时服务器上的Webform表结构:
create table `webform` (
`nid` double ,
`confirmation` blob ,
`teaser` tinyint (4),
`submit_text` varchar (765),
`submit_limit` tinyint (4),
`submit_interval` double ,
`additional_validate` blob ,
`additional_submit` blob ,
`confirmation_format` tinyint (4),
`submit_notice` tinyint (4),
`allow_draft` tinyint (4),
`redirect_url` varchar (765),
`block` tinyint (4),
`status` tinyint (4),
`auto_save` tinyint (4)
);
要插入的nid是唯一的,那么潜在的问题是什么?
