RE: Table statistics
May the gods of mySQL please forgive me. I just joined the list last night,
and thought, in seeing the question, I could provide a possible solution. I
was unaware that there was only one acceptable answer, and that all posts
had to be pre-checked. In the future I shall not make such a mistake again.
BTW: I've heard of, and use quite frequently, mysql_free_result(). In this
case, I cut-and-pasted (or is that cutted-and-pasted) existing code in an
existing file and at 12:30 a.m. I'm not my sharpest.
And Nick, it is PHP (4), not PERL. I don't know PERL, never written a line
of code in PERL and don't have any immediate plans to learn PERL.
Again I ask forgiveness of the lords and warlocks of the mySQL realm. If a
sacrifice is required, please advise as to the form.

I think Andy asked for a general solution, not for a solution in PHP. Not
all
people are working with PHP. There are a lot of other languages like C,
Perl,
Python, ... which all supports MySQL.
Finally a little note about your PHP Code: Did you ever heard about
mysql_free_result ?!

I did ask about this recently over in the php-general mailing list and someone said it was possible to do this in the Windows implementation and building a stand-alone PHP for Unix was documented in the INSTALL file. But I couldn't find it.

I keep apache access logs for web servers in MySQL databases and was wondering why the database for March's logs on a particular server was about a third of the size of February's even though the access stats looked about the same for those months. Hence the need to compare the table sizes. cheers, Andy - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

The "normal" way: SELECT COUNT(*) FROM table To get all tables in one statement... this is a hack, I'm not sure it will _allways_ give the correct answer, but try this: DESC SELECT * FROM table1,table2,table3,table4,table5 The row count is returned in the coulmn 'rows'. -- Roger query - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

This is actually PHP which I use a lot myself. But I wanted to know if
there was a simple command for this within mysql, or some option to
mysqlshow. It's far quicker to type somethinmg on the command line than
fire up a web browser, etc. And there must be a lot of MySQL installations
on servers which aren't also web servers, or don't have PHP installed,
etc.
Actually, it would be very nice if MySQL had a shell API - you can do this
to some extent by piping a command file into it but it involves a fair
amount of work to get the same functionality you get with, say, the C or
PHP interfaces.

Yes but this is PHP code that can only be run through a suitable web
server, browser, etc - I want a command line solution like mysqlshow ...
or from within the mysql client itself.

Actually, Nick; I don't think you're being presumptious, at all. Personally, I
prefer the ASS language since it allows me to access both XML and quasi-PHP APIs
in the same IDE-hole and across hardware/os environments; but hey that's me.
What do I know?

Re: Table statistics
Hi.
The simple way is use "SHOW TABLE STATUS FROM DATABASE_NAME" Like this in
php script (you also put this SQL into any application that you need)
";
echo "Table nameRecords";
while ($row=mysql_fetch_array($rs)) {
echo "",$row['Name'],"",number_format($row['Rows']),"";
}
echo "";
mysql_close ($conn);
?>
you will see the result in table (tag html) format with the name of data
table and it's number of records.

Might be helpful to the original poster to mention that this is Perl. He
didn't specify a language, so he may not comprehend what you've offered.
I don't mean this as a criticism, but it's interesting that we seem to often
assume that Perl is THE language for scripting MySQL. Not true, of course.
In fact, I'm finding Python easier, except for the blasted printf type
formatting, whose syntax was driving me batty yesterday until... well, I
could go on, but I won't.
