Question

我正在尝试更新数据库中的字段，一切正常。但是，每当我尝试更新表数据时，我都会收到错误代码“错误代码1054。”“ where子句”中的未知列“ userCertificateID”

CREATE TABLE `userCertificate` (
  `userCertificateID` int(11) NOT NULL AUTO_INCREMENT,
  `userID` varchar(45) DEFAULT NULL,
  `certificatename` varchar(45) DEFAULT NULL,
  `organization` varchar(45) DEFAULT NULL,
  `location` varchar(45) DEFAULT NULL,
  `startdate` varchar(45) DEFAULT NULL,
  `enddate` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`userCertificateID`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;


UPDATE userExperience 
SET certificatename = 'PMPPP' 
  , organization = 'hello' 
  , location = 'Canada' 
  , startdate = '2019-12-31' 
  , enddate = '2019-12-31'
WHERE userCertificateID = 4

在mysql中，它强调了组织并说：“组织在此位置无效，需要一个标识符。

您正在更新错误的表，请尝试：

UPDATE userCertificate 
SET certificatename = 'PMPPP' 
  , organization = 'hello' 
  , location = 'Canada' 
  , startdate = '2019-12-31' 
  , enddate = '2019-12-31'
WHERE userCertificateID = 4

SQL语句在where子句中的未知列
