Re: Total Counts, Multi-Report Questions
In the last episode (Feb 12), Sue Cram said: I have a request for a list of database entries Select x,y,z, etc that is now working OK. I have several questions, however. Here they are: 1.. Can I add a total line at the bottom of the report (ex: Total Selected: 23) for the total number of entries that are listed in the report? It's your report, you can put whatever you want in :) Simply print the size of the resultset of your main query, or if whatever language/reporting tool you're using can't do that, just do a SELECT COUNT(*) with the same WHERE clause. 2.. I want to print the same information but sorted in a different order on a second page of the report. Can I do that in one Select statement? If your language supports it, you can re-sort your resultset with a custom comparison fuction and display it again. Otherwise, you'll need another SELECT. 3.. If I need multiple select statements, is there a delimiter that says This is the end of my first select statement - the next thing you see is going to be a new select statement, so that all the necessary pages can be printed together in one job? So you want the same records to be returned in two orders, but as one resultset? Stick two queries together with a UNION ALL keyword. http://dev.mysql.com/doc/mysql/en/union.html -- Dan Nelson [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: certain content is causing an error with INSERT - please help
Hi leegold,
I don't know what mysql_real_escape_string would do, because it isn't a
standard-php-function. So I don't regard it and talk about the basics.
In fact you have a string delimiter in Librarian's Edition so you have to
escape it to make MySQL know where the string really ends.
There are two possibilities:
1. Double the quote to Librarian''s Edition with
$descrip_field=str_replace(','',$$descrip_field);
2. Use addslashes (as you described) to create Librarian\'s Edition.
Both ways work. The disadvantage of the second one is, that you might get
back a Librarian\'s Edition when you select from the database. In that
case you can't decide whether the user wanted that content or it occurred
because of escaping. Therefore I would always recommend the first way and
never(!) trust on any automatic escaping PHP would do for you.
By the way... you might get more probs when you have backslashes in you
strings. You should double them, too.
Frank
I fixed it. But I'm not clear on why. The following code ie. taking
the content and blatently putting the content through addslashes():
$descrip_field=addslashes($descrip_field);
Fixed it. But the code:
if (!get_magic_quotes_gpc()) {
$descrip_field = mysql_real_escape_string($descrip_field);
}
Did *not* fix it. So, to simplify this. Why would addslashes work and
the other code (which I see often as a recommend way to escape) not
work? This is a PHP question I suppose but I wanted to end the thread.
Sorry if I did not supply enough info up front for you to support.
AW: certain content is causing an error with INSERT - please help
OK, I use an older version of PHP where mysql_real_esacpe_strings isn't
avail. But nevertheless I would always prefer double-quoting with
$descrip_field=str_replace(','',$$descrip_field);
This is because I got lot's of Problems with different languages on
different databases when you try to make things easy of trust on automatism.
This always works.
Put all the checks and escapes into a function and call it instead of
mysql_real_escape_string... Then everything will be fine.

You have an error in your SQL syntax; check the manual that corresponds

Here's the content that will not insert:
iHow to Get It: A Guide to Defense - Related Information Resources/i
(DTIC, 2002; Librarian's Edition). A reference published by the Defense
Technical Information Service. The inspiration for this document.
Without special treatment the single quote (apostrophe) in Librarian's
terminates the string, leaving the rest as nonsense SQL.
I'm using PHP so I run the code below (note I think magic quotes might
be enabled on my server so the mysql_real_escape_string in the code
below might never be runned) but in any event it is escaped with:
if (!get_magic_quotes_gpc()) {
$descrip_field = mysql_real_escape_string($descrip_field);
}
The gpc stands for Get/Post/Cookie. I'd guess that $descrip_field didn't
come directly from a Get, Post, or Cookie, so magic_quotes didn't affect it.
In that case, you have to escape it by hand with mysql_real_escape_string,
but you don't do that because magic_quotes_gpc is on. I think this is a
good example of why magic_quotes is a bad idea. Better to turn it off and
then *always* process your strings.
I do the same escape for the title field tooThen futher down in the
code actual INSERT code is:
mysql_query(INSERT INTO howto.page (title, descrip) VALUES
('$title_field', '$descrip_field'))
or die (Can't connect because .mysql_error());
$page_id1 = mysql_insert_id();
if ($page_id1 == '0' ) { die ('died : page_id1=0'); }
It is good that you are checking for errors and printing them when you get
them, but often the error comes from the SQL statement not being what you
think it is (as happened here, I think). You would stand a better chance of
catching that if you included the actual SQL in the error message. I would
use something like
$query = INSERT INTO howto.page (title, descrip)
VALUES ('$title_field', '$descrip_field');
mysql_query($query) or die (Query: .$query.\n failed with error:
.mysql_error().\n);
That way, you see the actual query that was sent, as well as the error from
mysql.
What's wrong??? It inserts for everything else OK, but just won't insert
when i try with the content i cited?
Thanks,

mysql_real_escape_string() should work. The problem is that it wasn't being
called when it needed to be.

select where multiple joined records match
I'm trying to figure out how to select all the records in one table which have multiple specified records in a second table. My MySQL is version 4.0.23a, if that makes a difference. Here's a simplified version of my problem. I have two tables, resources and goals. resources table: ID TITLE 1 civil war women 2 bunnies on the plain 3 North Carolina and WWII 4 geodesic domes goals table: ID RESOURCE_ID GRADE SUBJECT 1 11 English 2 11 Soc 3 12 English 4 21 English 5 23 Soc 6 32 English 7 41 English Now, how do I select all the resources which have 1st and 2nd grade English goals? If I just do: Select * from resources, goals where ((resources.ID = goals.RESOURCE_ID) and (SUBJECT=English) and ((GRADE=1) and (GRADE=2))); I'll get no results, since no record of the joined set will have more than one grade. I can't just put 'or' between the Grade conditions; that would give resources 1, 2, 3, and 4, when only 1 really should match. My real problem is slightly more complex, as the 'goals' table also contains an additional field which might be searched on. I'm thinking it's time for me to go into the deep end of SQL (MySQL, actually), and my old O'Reilly MySQL mSQL book isn't doing the trick.

AW: AW: Slow Replication
We did get the problem kind of solved up to now. We basically use as advised the option innodb flush_log_at_trx_commit=2. This did get the timelage solved. I still do not really understand why we had to speed the slave up like this because it should have been faster due to the hardware already. I guess it is just as Alec said that the fact of using a single-threaded Slave-SQL thread slows the slove down a whole lot. Does anyone have any solution or suggestion how to work around that? I don't really feel good using the flush_log_at_trx_commit option. P.S.: The old Show Master or slave status information basically showed that the I/O Thread has been up to date and the SQL Thread of the slave lagged.

Or is there any way which could explain an IO bottleneck even though the slave is not running as many selects as the master is? In this case we are talking about one replicated database on a dedicated slave system. As I understand the previous posts, the problem is that the replication process is single-threaded while the updates on the original master are multi-threaded. On the original server, if Update 1 stalls because it has to fetch data of disk, Update 2 can proceed. If Update 2 stalls, Update 3 can proceed - and so on. This means firstly that Updates which can take advantage of the cache take no effective time - they come in, do their job, and exit while peer updates are stalled in Disk wait. This also means that lower-level software can optimise disk performance by re-ordering IO operations to minimise head movements. In my experience, having up to 4 parallel streams of disk operations, and allowing the disk to pick its preferred order of execution, usually adds about 50% to disk performance and can double it. However, when they are replicated to the slave server, the updates are put into a strictly First In, First out queue. If Update 1 stalls, Update 2 cannot be started - and nor can Update 3. When Update 3 does finally start, it cannot overlap the others, so that the time it takes, albeit small because it does not access disk, is added on to the other times rather than included within them. And since you are performing strictly one operation at a time (on the Updates side at least) Raid 0 does not help you, because there are no overlapping reads to get from alternate disks.

Re: Where's my ODBC icon?

Re: Where's my ODBC icon?
The ODBC control applet in Windows can be found in two places:br 1. Control Panel. 2. Administrative Tools (if you are using Windows 2000 or XP).br If you have Windows 2000 or XP, the easiest way to find it is to find your Administrative Tools folder (usually you need to tweak the Start menu to make it visible) and double click on the Data Sources (ODBC) icon. If you have Windows XP you can also open control panel and use the Administrative Tools icon in there. If you don't have Windows 2000 or XP, you need to find a file called odbccp32.cpl (or similar). If this is placed in the windows\system directory it should be visible in Control Panel. If it is not visible, you should use TweakUI to enable it. TweakUI is a Microsoft utility and can be found by searching on download.com . Cheers Andrew.

Re: Where's my ODBC icon?
However, when I double-clicked odbccp32.cpl, I was rewarded with something similar to what I got before. Not sure what you are looking for then. The myODBC driver should not need configuring, beyond setting up data sources, which is exactly what the control panel applet does for you. There is no program to launch - you configure a data source to allow you to access data, then use your ODBC-capable program to connect to that data source. Start up the ODBC applet and change to the System DSN tab. Next, add a new data source which uses the myODBC driver to connect to the database you want to access via ODBC. Once you have done this, you can then connect to the data source from your ODBC-capable program using the name of the data source. Cheers Andrew.

more complexity (was: select where multiple joined records match)
Thank you kindly for your gracious help. I am making much progress (the 'as r' and 'as g' syntax is helpful; I'd forgotten about it since I'm doing most of this through Perl; thanks). I played with the COUNT solution for a while and was initially encouraged, nay, ecstatic. However, I was getting weird results and realized that I had left out a wrinkle in my example (and my thinking): the extra field in my goals table means that the other values can, as a group, be repeated for several rows. This seems to keep this solution from working. Mea culpa; my example wasn't adequate. There might be multiple records with a given subject and grade combination, due to the additional field (called GoalNumber) in the goals table. The combination of ResourceID, Subject, Grade, and GoalNumber will be unique, but the combination of ResourceID, Subject, and Grade need not be. Here's a revision of my example. resources table: ID TITLE 1 Got Your Nose 2 Goats and Waterfowl: A Promising Alliance 3 North Carolina and WWIIb 4 Geodesic Domes - Ivy Revolution goals table: (I know all the numbers make it hard to read, sorry; I'll try to improve readability by putting a blank line before a new RESOURCE_ID). ID RESOURCE_ID GRADE GOALNUMBER SUBJECT 1 11 1 English 2 11 2 English 3 11 3 English 4 11 1 Soc 5 12 5 English 6 12 6 English 7 12 1 English 8 12 2 English 9 21 1 English 10 23 1 Soc 11 32 1 English 12 32 7 English 13 32 9 English 14 41 1 English Now, if I understand how this is working: SELECT r.TITLE FROM resources r JOIN goals g ON (r.ID=g.RESOURCE_ID) WHERE g.SUBJECT = 'English' AND (g.GRADE = 1 OR g.GRADE = 2) GROUP BY r.ID HAVING COUNT(*) = 2; will give an incorrect result, because the number of rows returned for each matching ID will be unpredictable. It could be 7 rows for ID = 1 (which is a correct match), or 3 rows for ID = 3 (which shouldn't match since it only has grade 2). I wish the EXISTS solution offered by Mr. Brawley would work, but thanks to Mr. Stassen for the clue about MySQL version. I tried it anyway at the command line but, of course, it didn't work. I also found a reference to an INTERSECTION keyword and experimented with it briefly; I couldn't find a document that listed when certain features came into MySQL, so I don't know if INTERSECTION is completely out of the picture, though UNION seems to have arrived after 4.0. Is there such a document? Or do I have to look at the change log for each version?

I have several questions, however. Here they are: 1.. Can I add a total line at the bottom of the report (ex: Total Selected: 23) for the total number of entries that are listed in the report? It's your report, you can put whatever you want in :) Simply print the size of the resultset of your main query, or if whatever language/reporting tool you're using can't do that, just do a SELECT COUNT(*) with the same WHERE clause. 2.. I want to print the same information but sorted in a different order on a second page of the report. Can I do that in one Select statement? If your language supports it, you can re-sort your resultset with a custom comparison fuction and display it again. Otherwise, you'll need another SELECT. 3.. If I need multiple select statements, is there a delimiter that says This is the end of my first select statement - the next thing you see is going to be a new select statement, so that all the necessary pages can be printed together in one job? So you want the same records to be returned in two orders, but as one resultset?
