Re: [PHP-DB] in-line function?

Ohhh.. sorry for that. it's quite simple, i'm wondering if
we can have something like those in-line functions in C++:
class someCLASS {
var $varLength;

inline function length() {

}
i expect it will make PHP script speed up a bit, coding
easier, etc... but not sure it will do or not. :)
What would be the difference (besides putting the word inline in front
of the function)?

Re: [PHP-DB] How to find the autoincremented number?
http://www.php.net/manual/en/function.mysql-insert-id.php
David Chamberlin wrote:
Hey,
Most of the tables I use identify things using an id which is
auto-generated using autoincrement. However I can't seem to figure
out a good way to find what value was generated for the ID.
For example, let's say I generate a new entry and want to e-mail out a
link to it and the link identifies the entry by ID. Currently, the
only way I can figure to do this is to first do the INSERT and then do
a SELECT on some unique information that I just inserted (e.g.,
submitter's ID and last-modified date). So for example, I would have:
function addNewEntry( $stuffToPutIn ){
$sql = INSERT INTO myTable $stuffToPutIn;
// I use pearDB with mysql
$result = $this-db-query( $sql );
checkDbResult( $result );
$sql = SELECT id FROM myTable WHERE .
(last_modified_by = $userId) AND .
(last_modified_time = $currentTime);
$result = $this-db-getAll( $sql );
checkDbResult( $result );
$entry = $result[0];
$linkAddress = $baseEntryURL.'?entryId='.$entry-id;
mailOutLink( $linkAddress );
}
What I'd really like to do is get rid of that SELECT or at least make
it less hacky to find out what the id was that got autogenerated.
Any ideas?
Thanks,
Dave

I could concat when selecting, but it will be used in the where clause
(it is neccesary to do it like this, I'm also md5ing it but forgot to
mention that), and I'm guessing it would be bad for the server to have
to concat and md5 in the where clause.

You'll have to do it after. Id probably doesn't even have a value since
you're just creating the row.
But, why do it this way? Why not add two more columns where you put in
'whatever' and 'whatever', then do the CONCAT when you actually SELECT
out the data. Then nothing is repeated. With your method, what if the ID
ever changes, then you'll have two columns to update.

I'm trying to make a customised session system (I could use PHP's built-in one, but I need a lot more control than it offers). I could use the autoincremented id in a cookie, but it would be easy for a hacker to change the cookie to gain access to others' data. John W. Holmes wrote: I could concat when selecting, but it will be used in the where clause (it is neccesary to do it like this, I'm also md5ing it but forgot to mention that), and I'm guessing it would be bad for the server to have to concat and md5 in the where clause.

Re: [PHP-DB] Deleting topics older than 2 hours?
Sounds to me like you didn't understand the question. The table structure is something like: topics_ | id | forum | author | subject | posttime | - _posts | id | topic | author | message | posttime| - The problem is, if I run a query like (I know the query is probably wrong, I'm just writing it now): delete from topics where posttime + interval 2 hours now() I would leave orphan posts inside of that topic. I'm not sure how (or if it's even possible) to delete the posts as the topic is deleted. DL Neil wrote: Sorry Leif, but CrystalBall v2.6 is currently unable to help. The word WHERE features.

Re: [PHP-DB] Performance for how many columns to update?
Yes, I know that one query is more efficient than 3, but I'm trying to do a mysql_fetch_array that automatically changes the row at the end of the script if it has changed. I'm trying to decide whether to make it only update the changed rows or be lazy and make it update them all if only 1 has changed. Peter Beckman wrote: Straight from the MySQL Documentation, which is where you should look first always: http://www.mysql.com/documentation/mysql/bychapter/manual_MySQL_Optimisation.html#Update_speed 5.2.10 Speed of UPDATE Queries Update queries are optimised as a SELECT query with the additional overhead of a write. The speed of the write is dependent on the size of the data that is being updated and the number of indexes that are updated. Indexes that are not changed will not be updated. Also, another way to get fast updates is to delay updates and then do many updates in a row later. Doing many updates in a row is much quicker than doing one at a time if you lock the table. Note that, with dynamic record format, updating a record to a longer total length may split the record. So if you do this often, it is very important to OPTIMIZE TABLE sometimes. See section 4.5.1 OPTIMIZE TABLE Syntax. If you aren't doing an update of 50K per row, updating 3 columns instead of 1 will be much quicker (quoted from the manual). If you are doing 10,000 updates, read more of the manual on the syntax of UPDATE because you can delay your updates which allows MYSQL to update the table at its leisure which offers better performance.

The order by clause is the killer. It forces the server to rebuild the

want the highest id, use MAX(id) .

In my attempts to optimize, I changed it to a multi-table query that looked something like select count(*) as cnt,species.name,pets.species from pets,species where species.id=pets.species group by pets.species order by cnt desc limit 1. Now, the speed of the page loading is up to 10 seconds! Was the array method the better way? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Searching everything?
Is there any way to search *every*thing in my database (using mysql)? I am thinking of a query somethng like select * from * where * LIKE '%putsearchhere%'. This would help a lot when searching for inappropriate language. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Any idea what's wrog with this query?
I have a field in one of my tables called when, which is type timestamp. I'm trying to use some of the date functions to get data from it, but it's not working. The return from mysql_error() is not helpful. Any ideas? Here's my query: $query = mysql_query(select month(when) as month,year(when) as year,dayofmonth(when) as day,hour(when) as hour,minute(when) as minute,second(when) as second from table) or print Error: .mysql_error(); -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It worked, thanks alot! on 4/18/02 1:43 PM, Paul Edmondson at [EMAIL PROTECTED] wrote: see http://www.mysql.com/doc/R/e/Reserved_words.html Your column called 'when' is a reserved word. Thats my first guess at your problem. I've come across this before with MySQL accepting column names that are reserved words. Try changing the column name to something else and try again.

[PHP-DB] What is mysql error 28?
I have a website which has, among other things, virtual items. The items are stored in table items, the different types of items in item_types. I use the following query to get a user's items: SELECT DISTINCT t1.id,t1.itemtype,t2.name FROM items as t1,item_types as t2 WHERE (t1.itemtype = t2.id AND t1.owner = '$theirrealinfo[username]' AND t1.placein='inventory') A few minutes ago, items mysteriosly started getting then followowing error from mysql_error(): Got error 28 in table handler. Thanks to anyone who can help! P.S. They just started working again. I'm still sending this because I want to know what was wrong. Thanks again!
[PHP-DB] Best way to not display frozen users?
I run a gaming website. Sometimes, I have to freeze users for one thing or another. But, since there are lots of tables involving users that get displayed to other users, they still get seen. One solution to this seems to be to have an array of frozen users in the header, which I check when displaying user-related things. Is this the best solution, and if it is, what is the best way to do it? Thanks! -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB] Please help me! :(
I have a site where things in the database have ids. When something new is
added, it gets an id one higher than the highest existing id. I use code
something like this:
$gethighestid = mysql_fetch_array(mysql_query(select id from table order by
id desc limit 1));
$tobeid = $gethighestid[id]+1;
mysql_query(insert into table(id,othercolumn,othercolumn2)
values('$tobeid','something','something'));
The thing is, I just got two rows with duplicate ids. Aparantley, two
people must of added two things at just the right times to make the same id.
Is there any way that will reduce, or eliminate, the time gap between
getting id and inserting?

[PHP-DB] Is there a better way to do this?
I operate a small game site for kids. On this site, the players can, among other things, buy virtual items. I have each item stored in a table called items in a mysql database. The type is one column in that table, but it is a number, not a name. When I want to display items with the item name, I have to send a query to the item_types table to get the type name. The problem is, if a user has 50 items, it takes 50 queries to get the types.
