使用预准备语句我试图在表格中插入值电子邮件中没有列名但很明显我在项目的任何地方都没有错过电子邮件。
RegistrationAcitivity.java
public void reg_submit(View v){
DataHelper con=new DataHelper(this);
GetterRegistration model=new GetterRegistration();
SQLiteDatabase db = con.getWritableDatabase();
**String sql="insert into registration(name,email,password)values(?,?,?)";**
SQLiteStatement stmt = db.compileStatement(sql);
stmt.bindString(1, model.getName());
stmt.bindString(2, model.getEmail());
stmt.bindString(3, model.getPassword());
stmt.execute();
db.close();
Intent in = new Intent(this, CocomoActivity.class);
startActivityForResult(in, requestCode);
}
}
DataHelper.java
public class DataHelper extends SQLiteOpenHelper {
public static final String TABLE_COMMENTS = "registration";
public static final String id= "_id";
public static final String name = "name";
**public static final String email = "email";**
public static final String password = "password";
private static final String DATABASE_NAME = "mydb.db";
private static final int DATABASE_VERSION = 1;
// Database creation sql statement
private static final String DATABASE_CREATE = "create table "
+ TABLE_COMMENTS + "( " + id
+ " integer primary key autoincrement, " + name
+ " text not null,"+email
+"text not null," +password
+"text not null)";
这是Logcat中的错误报告
