INSERT INTO准备好的语句，PHP MYSQL，优化了很多专栏

Question

Please help me to understand how to optimize mysql queries in php. When you have a lot of columns, prepared statement looks like

$inst = $db->prepare("insert into year_$year (user_name,type_of_day,month_row,day_1,day_2,day_3,day_4,day_5,day_6,day_7,day_8,day_9,
day_10,day_11,day_12,day_13,day_14,day_15,day_16,day_17,day_18,day_19,day_20,day_21,day_22,day_23,day_24,day_25,day_26,day_27,day_28,day_29,day_30,day_31)
values
(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");

$inst->execute($chunk_post[$init]);

this code is from here: http://govnokod.ru/php?page=356 where people ridicule shitty codes.

I do not understand how to do it in other way.

Answer 1

A little Joke:

u can use for ($i = 1; $i <= 31; i++) {} to construct your Query ;)

The Reality:

Read about Database Normalization here: http://databases.about.com/od/specificproducts/a/normalization.htm

Your Ultimate goal should be the third normal form.

You should think about some Day which are linked to one Month.

think about a table month and table day.

Read about SQL JOIN.

Sure, you will not have the DataType DateTime?

This Question is way to broad to give you a solution instead of an learn here, learn there answer. Your Question is about basics.
