答案 0 :(得分：2)
您的第二个SQL查询中显然有错误：
UPDATE studentreg SET ( regNo , name , sname , idNo , age , birthD , gen , national , relegion , fee , institute , pro , sDay , eMail , phnNo, address , img ) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?) WHERE regNo = '+rNo+
必须以此形式定义更新：
UPDATE studentreg SET regNo = ?, name = ?, ...
等等......
答案 1 :(得分：0)
您正在使用类似插入的更新：
UPDATE studentreg SET ( regNo , name , sname , idNo , age , birthD , gen , national , relegion , fee , institute , pro , sDay , eMail , phnNo, address , img ) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?) WHERE regNo = '+rNo+'"
您可以执行以下操作：
UPDATE Table SET regNo = i.regNo, name = i.Name, ...
FROM (SELECT Col1, Col2 FROM other_table WHERE regNo = 'rNo') i
