There is a command in MySQL that can show montlhy entries on a database ?
This is just a simple question because I don't know so much about MySQL. There is any command that can show the total of entries in a month?. Something like this:
2010-08-10 Total entries: 8
2010-10-11 Total entries: 9
I just need to know which command in MySQL can show me the total entry in one month.
2010-08-10 Total entries: 8
2010-10-11 Total entries: 9

Monthly or daily? Your example seems to mean daily.
Anyway for monthly:
select month(datetime_column), year(datetime_column), count(whatever_preferably_ indexed_co lumn) from table_name group by month(datetime_column), year(datetime_column);
If daily
select date(datetime column), count(whatever_preferably_ indexed_co lumn) from table_name
group by daate(datetime_column);
Anyway for monthly:
select month(datetime_column), year(datetime_column), count(whatever_preferably_
If daily
select date(datetime column), count(whatever_preferably_
group by daate(datetime_column);
Note that I included year(datetime_column) because your table might span multiple years. Without it, you will count entries for january of 2009 and 2010 together, for example.

Here is an example what I want, and it is a monthly entry not daily. Just supose that in january only eleven persons access to a webpage , So I should see something like this on mysql:
+----------+-------------- --+
|Month | Total Entries |
+----------+-------------- --+
| 01 | 3 |
+----------+-------------- --+
+----------+--------------
|Month | Total Entries |
+----------+--------------
| 01 | 3 |
+----------+--------------
Have you even tested the sample code already given to you? I guess the only thing missing there is to alias the table columns. I would rather point you to the right page where you can learn it:
http://dev.mysql.com/doc/refman/5.1/en/select.html
then search the page for "alias"
http://dev.mysql.com/doc/refman/5.1/en/select.html

I have run all the MySQL commands but how I can make that this one just show me one month and not all the months ?. As I said before, I just need that the SQL command shows me one month not all of them
select month(06) as Month,concat('total entries',count(*)) as totalEntries from sqlguestbook group by month(06);
I just tried to used but I get the following screen:
+----------+-------------- --+
|Month | Total Entries |
+----------+-------------- --+
| NULL | 3 |
+----------+-------------- --+
It never show me the month just the word NULL and not the month (which is june as you see on the command).
select month(06) as Month,concat('total entries',count(*)) as totalEntries from sqlguestbook group by month(06);

When I write this command on MySQL:
Select '06' as Month count(*) as TotalEntries from totalEntries Where month(datetime_column)=6 and year(datetime_column)=2011
I get this error message:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'count(*) as TotalEntries from totalEntries Where month (entry_date)=6 and year(e' at line 1
Select '06' as Month count(*) as TotalEntries from totalEntries Where month(datetime_column)=6 and year(datetime_column)=2011
I get this error message:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'count(*) as TotalEntries from totalEntries Where month (entry_date)=6 and year(e' at line 1
Typo. Add a comma before count.
select month(DATECOLUMN) as Month,concat('total entries',count(*)) as totalEntries from tablename group by month(DATECOLUMN);
