我正在尝试将数据插入数据库，但遇到问题，错误说：
android.database.sqlite.SQLiteDatatypeMismatchException: datatype mismatch (code 20)
错误1说： -
com.example.db.myDBClass.InsertData(myDBClass.java:51)
行是： -
long rows = db.insert(TABLE_MEMBER, null, Val);
错误2说： -
com.example.db.UploadActivity.InsertDatas(UploadActivity.java:271)
行是： -
long saveStatus = myDb.InsertData(editImageName.getText().toString(),editPersonName.getText().toString(),
editPersonaEmail.getText().toString(), editPersonTelephone.getText().toString());
错误3说： -
com.example.db.UploadActivity$3.onClick(UploadActivity.java:429)
行是： -
InsertDatas();
日志： -
