java.sql.SQLException：列计数不'；我的数据库第1行和第1列的t匹配值计数是自动证明的

我正在尝试在数据库中插入值，这样，如果用户选择标记库，则标记将被保存，如果用户选择成绩库标记feild为空且应存储成绩，则我的主键是gid，它是自动识别的，sid是forign键。如果有人能帮我，我无法获取并解决此错误很高兴

指定insert语句中的列

String qry="insert into gpa (col1, ... , col7) values(?,?,?,?,?,?,?)";

列的计数必须与问号的计数匹配

String qry="insert into gpa (col1, ... , col7) values(?,?,?,?,?,?,?)";
