Android SQLite更新查询不工作？

我收到了这个错误消息。你能指出罪犯吗

public void AddViewCount(String chname)
{
   String selectQuery = "UPDATE  channel_login SET TimesViewed=TimesViewed+1 WHERE channelName="+chname ;
   SQLiteDatabase db = this.getWritableDatabase();
   Cursor cursor = db.rawQuery(selectQuery, null);
   System.out.print("Count"+cursor.getCount());  

}

请尝试以下操作：

android.database.sqlite.SQLiteException: no such column: Sat1  
(code   1):,while compiling: UPDATE  channel_login SET       
TimesViewed=TimesViewed+1 WHERE channelName=Sat1

在文本值周围添加“”应该有效。另外，除非您需要游标计数，否则您可以使用

db.execSQL（selectQuery）以执行更新

public void AddViewCount(String chname)
{
   String selectQuery = "UPDATE  channel_login SET TimesViewed=TimesViewed+1 WHERE channelName='"+chname+"'";
   SQLiteDatabase db = this.getWritableDatabase();
   Cursor cursor = db.rawQuery(selectQuery, null);
   System.out.print("Count"+cursor.getCount());  

}
