[PHP-DB] select from multi tables
Hi All, I have a situation where I need to get data from more than one table, but where the fields in the table are identical, the two tables are holding data for different years. The queries I would like to execute would be something along the lines of this: - SELECT SUM(T1.F1) AS C1, SUM(T2.F1) AS C2 FROM T1, T2 Which I would like to give the total of T1.F1 in C1 and the total of T2.F1 in C2. What I get however is the sum of T1.F1 * sum of T2.F1 in both result fields and the number of records found as being the sum of the number of records in T1 * those in T2. What I would like to do eventually with this is get the sum of F1 from any number of tables each representing a year as I don't want to lump all my data into one big table that will get out of hand. Can anyone tell me the right way to go about this? Cheers Dan -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Re: select from multi tables
SELECT SUM(T1.F1) AS C1, SUM(T2.F1) AS C2 FROM T1, T2 Hi, T1,T2 is a join of the two tables which means that you combine each value of T1 with each value of T2. This is why you don't get the result you want. In your case I simply would do two querys as it won't make any problems: SELECT SUM T1.F1 FROM T1; SELECT SUM T2.F2 FROM T2; Regards, Bastian -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] form field rejection
You could also look at a site like javascript.internet.com and look up a
pre-written phone number validation script and do the validation on the
client side in addition to or instead of doing it on the server side.
One reason you may want to consider doing client-side validation for
something like this is consideration for your users. Not everyone has a DSL
or Cable connection, let alone T1 or T3. If one of your users fills out your
form, hits SUBMIT, then has to wait maybe 60 seconds round trip for the
server to report that the phone number was invalid, they're probably going
to get frustrated. Any time you can get away with client side form
validation, you should use it. Especially if you're backing it up with
server-side validation. It's much more user-friendly.
Server-side validation is good to double-check to make sure the form data
has not been tampered with and is still acceptable by the server and in the
event that the user has disabled JavaScript in the browser. It's also
necessary anytime you have to validate a form entry against a database (e.g.
checking to see if a username already exists on a user account creation
form).

[PHP-DB] VFP 6 via ODBC and data integrity questions
Good day all, I have just began work on a project to let users subscribe to a service and place orders into a database that is VFP 6 based. Using PHP4, I am able to interface with their program (that also uses ODBC locally) in all aspects (INSERT, UPDATE, DELETE, and SELECT). My worries come when inserting a new user/order from the web. The morons who designed the database made the Primary Key as character and NULLable (once only of course), but I have to deal with that. My question is this... How can I know the new user I INSERT will be unique? (the field is character, but counts like a number field) This especially holds true since I have to deal with local users possibly adding at the exact same moment as PHP (ie. a racing issue). Can anyone tell me how to avoid problems? Would odbc_prepare() reserve a new key for me? Thanks. Brian PJC Services P.S. Kudos to all of the developers.

[PHP-DB] heredoc and coding standards
I try to write very clean code. However, there is one thing that always bugs me - using heredoc syntax in a function. Code in the function really should be indented (or 4 spaces for PEAR types), but, to quote the documentation, the closing identifier must begin in the first column of the line. That means no tabs, right? So is that just the way it is? Do I just need to not worry about my tabs for heredoc?

No, I wouldn't think so, it's a native VFP function. I'm wondering if you could clone something, by using rand(), seeded with the unix time and client's IP number. Don't take me too seriously, I'm just musing here. How do I lock the database through PHP and ODBC for a moment?? I cannot find any information on this. Probably you can't. but I'm wondering if you could SELECT the keyvalue you need, then immediately execute an update, setting keyvalue to keyvalue + 1, assuming it's numeric. What would that be like, something along the lines of update keys ( keyvalue), ( str( val(keyvalue) + ) ) where tablename = 'var_tablename' The val expression converts the existing keyvalue to a numeric which allows a numeric one to be added, returning that expression as a string. (Unless I have their functionality reversed, but I hope you get the idea.) With his you don't have to worry about the lock and the value will be appropriately updated. Again the question is what kind of functions can you use through ODBC; I've not ever had to work with it. HTH - Miles Thompson Thanks for your help.

Re: [PHP-DB] VFP 6 via ODBC and data integrity questions
OK, I know what I have to do. I thank you for all of your help and I will use your idea of a select, then update and then capture all errors to try again. Hopefully, this will minimize problems in the future. Thanks, Brian PJC Services At 06:45 PM 2/3/2003, you wrote: At 06:25 PM 2/3/2003 -0500, Brian Evans wrote: Currently they are using a VFP client app, the actual program is not installed. I just discovered that the suggestion you offered (about a key table) is being used by this client. Would the sys() function work through ODBC w/o the full VFP install? No, I wouldn't think so, it's a native VFP function. I'm wondering if you could clone something, by using rand(), seeded with the unix time and client's IP number. Don't take me too seriously, I'm just musing here. How do I lock the database through PHP and ODBC for a moment?? I cannot find any information on this. Probably you can't. but I'm wondering if you could SELECT the keyvalue you need, then immediately execute an update, setting keyvalue to keyvalue + 1, assuming it's numeric. What would that be like, something along the lines of update keys ( keyvalue), ( str( val(keyvalue) + ) ) where tablename = 'var_tablename' The val expression converts the existing keyvalue to a numeric which allows a numeric one to be added, returning that expression as a string. (Unless I have their functionality reversed, but I hope you get the idea.) With his you don't have to worry about the lock and the value will be appropriately updated. Again the question is what kind of functions can you use through ODBC; I've not ever had to work with it. HTH - Miles Thompson Thanks for your help.

[PHP-DB] problems with variables
I want to pass some variables named a1, a2...aX in a form. So I wrote a
couple of lines to do the trick:
for($i=1;$i=$X;$i++)
{
echo input type=\hidden\ name=\q$i\ value=\$q$i\\n;
}
But there is just one problem. How do I pass the correct value?
This is what I want the loop to do:
echo input type=\hidden\ name=\q1\ value=\$q1\\n;
echo input type=\hidden\ name=\q2\ value=\$q2\\n;
...
...
So I want to make the variables $q1 .. $qX from q$i
Is this possible and if so, how?
Thanks for your support,
Marcel

Re: [PHP-DB] heredoc and coding standards
heredoc is the fastest way to get lazy. use inline php then, easier and can use tabs, no?

[PHP-DB] Re: heredoc and coding standards
Rob, I've come across the same dilema. To keep things clean while using the convenience of heredoc you can write the heredoc in a seperate file and include_once() the file.

[PHP-DB] Re: problems with variables
Sorry, I see that I've got the a's and q's mixed up.
I'll try to clarify it some more by giving an example with 2 variables.
$q1 = first_var;
$q2 = second_var;
for($i=1;$i=2;$i++)
{
echo input type=\hidden\ name=\q$i\ value=\$q$i\\n;
}
The output should now be:
input type=hidden name=q1 value=first_var
input type=hidden name=q2 value=\second_var
Hope you can help me,

As mentioned in another reply, in MySQL all fields can have quotes regardelss of

if(!is_numeric($value)) {
$value = ' . $value . ';

I guess this is mostly a MySQL question, but perhaps PHP has a solution...
I would like a foolproof way to determine whether a data value needs to be
quoted. Numeric data doesn't need quotes, but string data does.
I could use mysql_field_type and check if it's integer, float, double,
real, etc., but this seems fragile. I could easily miss one, or a new
version of MySQL could add a new one.
So how can I get the equivalent of a mysql_needs_quotes function?

[PHP-DB] Oracle 9.2 + IIS 5.0 + Win2k server + PHP 4.3 + ADODB 3.10
Hello folks, I need help with the following. I'm recording machine
production and 'health' status information into a Oracle 9.2 DB. That's
working great, rock solid, great admin tools, etc.
I've been trying to use the Rockwell Software tools to get the data out onto
the web in a pretty format, but Rockwell's tools are brittle, buggy, and
overpriced. Also, ASP + VBScript for my hacks is turning out to be crufty
and slow.
I have Oracle 9.2 sitting on a Win2k server that is the primary domain
controller. I've set up IIS with PHP, and everything is working great... It
can see all the extensions, and with a change to the permissions of the
oci.dll, PHP can see that too.
I'm wanting to use ADODB 3.1 as a cleaner interface to the Oracle database
via oci8. But no matter what I try, I get errors. These errors are not the
access is denied error I saw when oci.dll had the wrong perms. It seems I
get a warning in the ado...
Here is the code snippet from the testpage, tnsname has been changed to
protect the guilty... ;)
--
This is the dbtest.php file, based on samples given on the adodb page
--
?php
include('.\adodb\adodb.inc.php'); # load code common to ADOdb
include('.\adodb\tohtml.inc.php');
$conn = ADONewConnection('oci8'); # create a connection
# connect to Oracle OCI8 DB...
$conn-debug=true;
$conn-NConnect('', 'usr', 'usr_pwd', 'TNSName');
# select machines from machinetable
$recordSet = $conn-Execute(select * from machinetable);
if (!$recordSet)
print $conn-ErrorMsg();
else
while (!$recordSet-EOF) {
print $recordSet-fields[0].' '.$recordSet-fields[1].'BR';
$recordSet-MoveNext();
}
#$recordSet-Close(); # optional
#$conn-Close(); # optional
?
--
This is the error I get in my HTML page, when I browse to dbtest.php
--
Warning: _oci_open_server: in
D:\PHP\includes\adodb\drivers\adodb-oci8.inc.php on line 132
:
(oci8): select * from machinetable
:
---
adodb-oci8.inc.php is part of the adodb package, and I am getting a warning
at that line in the ADODB code.
Is this a bug? Should I try ADODB 2.5 instead since it's listed as being
more stable on the site?
Any and all help will be greatly appreciated. I'm trying to get a demo app
up and running in a few days so they don't think I'm nuts for trying
this... :)
