Keep Repeating The Same Select Query?

I didn't want to keep repeating the same select query, so I wrote this function. But it doesn't work:

$query = mysql_query("SELECT $what FROM $table");
}
select(*, products);

Strange Inconsistences When Repeating A Query More Than Twice In A Row

Jul 17, 2005

Here is a small sample program I wrote in PHP (running off Apache
1.3.31 w/ PHP 5.0.1) to help illustrates problem I'm having. The data
base is using DB2 V5R3M0. The client is WinXP machine using the iSeries
Client Access Driver ver 10.00.04.00 to connect to the database.

The problem is that executing the exact same SQL select statement more
than twice int a row stops produces results. The first two instances
will always produce the correct results but after that it will simply
return with no results found. I've also wrote the exact same test case
with other various ODBC APIs with the same results.

I've examining the ODBC driver trace log and I am unable to find any
noticable differences between a SQL statement producing the correct
results and one that produces a no results found message. I've tried
three different ODBC driver versions and have the same results.

NOTE: This doesn't occur for EVERY select statement but it does occur
for different files with various WHERE clauses but I've been unable to
determine any relationship between working and non working repeating
select statements.

Display SQL Query Results In A Repeating Table?

Nov 25, 2009

This is my first post here, but i've lurked for a while. I'm working on a website but have come across a major stumbling block in the code: I've managed to structure the search query but have 2 problems: I dont know how to code the results into the table, and make the table repeat itself 5 times per page (and recognise it needs a new page) And I cant test the search query because i cant get the results to display.

If any one could answer 1 or more of these problems and/or correct any error's i've made I'd jump for joy, as i feel i've been fumbling in the dark for the last week or so. Here's my code so far:

$connection = mysql_connect($hostname, $username, $password);
if (!$connection) {
die("A connection to the server could not be established");
}
//remember to select the database!
mysql_select_db($database) or die("Database could not be selected!");

Perform A Query Where List All Of Records While Repeating One Records?

Nov 8, 2010

Say I have a list of names each with an id number ranging from 1 to 10.  Is it possible to perform a query where you list all of these records while repeating one records.  For example could I do a query that lists record number 6 then 10, 9, 8, 7, 6 etc.  Or another example would be listing record number 10, then 10, 9, 8, 7, 6 etc?

currently i'm using 3 querys (i think thats too much).

and on the other way, what if i want to get ALL products of a specific category?can this also be done in one query?

Query - Create The Mysql Query To Get All Fields

Jul 17, 2005

I've a table "article".
Any article is of a type in table "type1" or "type2"
Each type may be of a model in table "model1" or "model2".
Each model can be on a certain make, also in 2 tables, "make1" and "make2".

they are a few possibilities.
"article" can be of "type1" or "type2"
"type1" can be of "model1" only - "type2" can be of "model1" or "model2"
"model1" can be of "make1" only - "model2" can be of "make1" or "make2"

"article" has "type.id" field (char10). If it start with "my" then it's a
"type2", otherwise is a "type1"
"type1" has only "model1.id" field. "type2" has "model1" and "model2"
fields. If one is filled, the other isn't
"model1" has only "make1.id" field. "model2" has "make1.id" and "make2.id"
fields. If one is filled, the other isn't

so here are the possibilities:
article -> type1 -> model1 -> make1
article -> type2 -> model1 -> make1
article -> type2 -> model2 -> make1
article -> type2 -> model2 -> make2

Now, I must create the mysql query to get all fields given the "article.id".
Is it possible ?
How ?
will this work ? in pseudo-code

article left join type1 articleid = type1id
inner join model1 type1id = model1id //inner because if type1, the model is
1
inner join make1 model1id = make1id //inner because if model1, the make is 1
left join type2 articleid = type2id
left join model1 type2id = model1id
left join model2 type2id = model2id
left join make1 model2id = make1id
left join make2 model2id = make2id

Random $var Repeating.

Jan 22, 2006

I'm trying to pull random lines from text file and print them from calling a variable but everytime I call the variable it pritns the same thing. Here is the code:

<?php
$var = file("vars.txt");
$returns = array("", "");
$var = str_replace($returns, "", $var);
foreach ($var as $num=>$line) {
$var[$num] = strtolower("$line");
}
$n = sizeof($var ) - 1;
$var = $var[rand(1, $n)];

echo $var;
echo $var;
echo $var;
echo $var;
echo $var;
echo $var;

?>

This prints:

line3
line3
line3
line3
line3
line3

When I want it to print each line randomly, like:

line9
line2
line6
line2
line1
line6

MySQL Query - 2 Steps In 1 Query?

Dec 22, 2003

I have two tables and the first one contains 2 main fields- 'user_id' and 'username'. The second table contains 2 main fields- 'poster_id' and 'message'. And what I need to do is lookup the user_id from the first table with the username, then pull * from the message_table if the poster_id matches the value pulled from the first table.

Now, I got this working without a problem at all but I had to use 2 queries to do it (1- pull the user_id from the first table by matching it with the username, then 2- using the first id, pull everything from the second table that matches it). Is there an easy way to do those 2 steps in 1 query? I know there must be some way since this seems like a fairly simple and routine problem, but I can't find it online or in any books I have here.

PHP Saying Error In Mysql Syntax, But Written My Mysql Query Browser!

Mar 21, 2007

I have a basic db that I access with MySQL query browser. Everything
seems fine to me but I am using this db as part of a php shopping
basket and when I try to add an item I get:

Notice: Query failed: 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 '>function.extract]: First argument should be an
array in functions.inc.php on line 31
Notice: Undefined variable: price in functions.inc.php on line 36
Notice: Undefined variable: price in functions.inc.php on line 39
Notice: Undefined variable: total in unctions.inc.php on line 39

I'm assuming the last three are caused by this problem as price should
be passed to the cart, and total is worked out using it. However
although I know mySQL code it was the MySQL query browser that
actually generated the code and I cannot see a way to view or debug
the code.

The db has one table in it which is made up of id, name, subname,
desc, and price.

Forms With Repeating Fields

Sep 26, 2007

This is probably a simple question but as a newbie I just aren't sure the best way to do it. I'm developing a site with a shopping cart type feature, items added to the cart are inserted into a database and then I want to display the cart and allow the user to delete items or change the quantity of any items.

I could have each cart item within its own form with its own 'update' button but I'd like to just have one form for the whole cart and one 'update' button if possible so when the form is submitted it goes through each record on the form and deletes the records that have the delete checkbox checked and updates the records which have changed quantities. I'm just not sure how to achieve this - Do I need to get my code to dynamically name the form fields (eg. ProductID1, ProductID2 etc.) and then how do I get it to loop through my form records?
