这是我的java方法,我用它来更新用户
在后端,我使用jdbc而不是jdbc模板来更新用户我无法插入countryid,因为错误显示没有找到countryid列名。这个错误显示counrtyid丢失了,但是在我的sql编辑器中,我发现查询是正确的
public User updateUsers(int id) throws SQLException {
User user = null;
Connection con = null;
PreparedStatement ps = null;
int active = 0;
try {
con = createConnection();
ps = con.prepareStatement(
" select UserMaster1.usermasterid,UserMaster1.FName,UserMaster1.LName,UserMaster1.Gender,UserMaster1.address,UserLogin.Email,UserLogin.Password,UserMaster1.MobileNo,country.countryname,s.state,UserMaster1.hobby "
+ " from UserMaster1 "
+ " INNER JOIN country ON UserMaster1.country=country.countryid "
+ " INNER JOIN state as s ON UserMaster1.state=s.stateid "
+ " INNER join hobbyMaster ON UserMaster1.hobby=hobbyMaster.HobbyId "
+ " INNER join UserLogin ON UserMaster1.usermasterid=UserLogin.usermasterid "
+ " where UserMaster1.usermasterid=? ");
ps.setInt(1, id);
ResultSet rs = ps.executeQuery();
while (rs.next()) {
user = new User();
user.setId(rs.getInt("usermasterid"));
user.setFname(rs.getString("FName"));
user.setLname(rs.getString("LName"));
user.setGender(rs.getString("Gender"));
user.setEmail(rs.getString("Email"));
user.setPassword(rs.getString("Password"));
user.setAddress(rs.getString("address"));
user.setMobile_no(rs.getInt("MobileNo"));
user.setCountry(rs.getString("countryid"));
user.setState(rs.getString("stateid"));
user.setHobby(rs.getInt("hobby"));
}
} finally {
if (ps != null) {
ps.close();
}
if (con != null) {
con.close();
}
}
return user;
}
``` `it is returning the user from the method at the technology side i am using spring-mvc i suppose it is not of the concern` 这是代码在执行时显示给我的错误。

原因是你通过
rs.getString("countryid")
但您没有在sql中选择它要解决这个问题,你需要添加
country.country.id
在您的选择中:
