sqlite 多条件查询

String[] columns={"kind","textnum","region"};//你要的数据
String 条件字段="NUMWEEK=? and YEAR=?", 
String[] selectionArgs={”星期一"，"2013"}；//具体的条件,注意要对应条件字段
Cursor cursor=db.query(表名, columns, 条件字段，selectionArgs, null, null, null, null);


		String strSql = "update appsort set number=number+1 where activityname='"+appSortInfo.getActivityName()+"' and packagename='"+appSortInfo.getPackageName()+"'";

select packagename from appsort where number >0 order by number desc limit 0,20

String sql = "select * from appsort where activityname=? and packagename=?";
	Cursor mCursor = db.rawQuery(sql,new String[]{"com.android.calendar.AllInOneActivity","com.google.android.calendar"}); 		mCursor.moveToNext();
