Android SQLite 多条件查询或删除

SQLiteDatabase db=dbHelper.getWritableDatabase();

db.delete("record","pulse=? and dia_pre=?",new String[]{record.get_pulse(),record.get_dia_pre()});//删除所有pulse等于给定值并且dia_pre等于给定值的记录

Cursor cursor=db.query( "record" ,null, "sys_pre>? and dia_pre<?" ,new String[]{ "120" , "85"} ,null,null,null) ; //多条件查询记得String是数组
