Same Mysql Query Doesn't Always Return A Result
We have no access to a mysql NG on my provider's server, so we ask here: We have a long query (long in text) with a UNION between 2 select. We have been informed that some times the query doesn't return any result. We have tried on our server and we always get a result. BUT, trying on the hosting server, many times the query doesn't return any result and doesn't get any error. Any idea ? does Union have any problem ? how to check if the query failed ? My hoster said that sometimes the table can be locked (if the server is overloaded) and then mysql doesn't return any result, but this seems to me an aberration. the query takes about 0.0050 sec to execute when it doesn't return any result, and 0.030 when I get results
How To Get Mysql Query Result Into Temp. Txt File
I did a lite search in the archive but didn't find anything specific to my problem. Here is what I am trying to do: I've got a table with about 25k entries of company addresses. I need to be able to pull specific data out of the table and put it in a temporary text file and then display the result in the browser for the user to save locally. The query part and the format of the data is all simple enough but I am having trouble figuring out how to get the data from the query into a temporary text file and then displaying that file. here is what I whipped up but it obviously doesn't work: Code: <? $tmpfname = tempnam("/path/to/file/", "FOO"); $list = mysql_query("select * from FH_LIST where State='AK'"); while ($list_results = mysql_fetch_array($list)) { $data = blah blah blah; fwrite($tmpfname, ".$data "); } fopen($tmpfname, "r"); fpassthru($tmpfname); ?> I get an error message saying: Warning: Supplied argument is not a valid File-Handle resource (referring to $data).
MySQL Result Is Empty, But The Query Is Correct
I have written a script that grabs info from a database, and outputs it to a form. I figured I'd tidy things up a bit, and use a function to handle the queries, where I had previously hardcoded almost the same query several times. Code:
Selecting A Random Row Of A Mysql Query Result?
Let say I have a mysql query, which might yield more than 1 row when queried. How can I set up the query, so that it RANDOMLY selects one of the results? I know that I can do a LIMIT 1 command, but this will always yield the first row.
Can I Put A Mysql Query Result Directly Into A Multidimensional Array?
I have two joined tables: Departments - which contains the department description and a key Positions - which contains position data What I'm attempting to achieve is to display the department title in one table cell and then list all the positions associated with that department in the cell under neither the title.

How To Populate HTML Form From PHP/MySQL
I have found many examples of how to access an HTML text field from PHP, but cannot find the reverse - how to load an HTML form from a MySQL database. Specifically, I have an HTML form which contains several text boxes that correspond to the fields in a MySQL file. What I want to do is call a PHP form that reads one record from MySQL and then populates all of the HTML fields on the calling form. The call to MySQL is not a problem - that works and I can use "Echo" to verify that I have successfully read a record. Now, how do I get that data back into the original HTML form?
Populate MySQL With Multiple Text Box Entries
I have about 300 rows of mysql data which I have chosen to diplay with a text box at the end of each row, that is available for adding comments. I would like to be able to add comments to entries and then have an update scripte that would take the text box, named "MC" and place the data in its row identified by a hidden field which would corrrespond to the Primary Key of the MySQL Database. I've done something similar using check box arrays, ie. Checkbox name="MC[]" My question is whether I can write a script that would test for a value in the corresponding text box, and update the MySQL data accordingly. I have also provided in my display script that if the MC column is already populated in MySQL it will not display in the form.
Populate A Calendar Page With MySQL Data
I'm trying to figure out the best way to populate a Calendar page with data from a database. I have the code that will generate the Table with Days of the week, but I'm at a loss on how to populate this with data from a database. Do I build the calendar and then for every day that I generate a cell, query the DB or should I load the DB in an Array and compare that to the date of the cell?

Echo A $result Of Query?
Trying to have an echo display a result from a query. Not such a hard concept. Yet I am having trouble. What good is the data without analysis. Here is what I am using to try and grab result. Have been told it looks correct, must be missing something small. When this runs, alternate echo displays in browser. So you know: 'testdata' is the table 'score' & 'id' are columns or fields. Almost think it is missing a table structure to display in. Looking for player name column and score column (for the sake of example). Code:

Limit Query Result According To A Criteria
I have the following code which doesn't work: "SELECT COUNT(*) AS total FROM $table_name WHERE certain criteria HAVING total<=100"; The query above doesn't work and i get zero results. In general the query take lots of time mainly because the criteria is not specific enougth and I get many many hits. I want to stop the query after getting the first 100 hits according to a certain criteria. When I use LIMIT 0,100 and not HAVING i get result from the first 100 records in the table but my table contain few million records.

Easiest Way To Print The Result Of A Query
I am using the following code: $host =""; $username=""; $password=""; $database="123"; mysql_connect($host,$username,$password); @mysql_select_db($database) or die( "Unable to select database"); $query="SELECT SUM(rcountry) FROM 123 WHERE sessid = '$PHPSESSID'"; $result=mysql_query($query); $num=mysql_num_rows($result); mysql_close(); Whats the easiest way to print the results of the query? I just need the value returned by this section: $query="SELECT SUM(rcountry) FROM 123 WHERE sessid = '$PHPSESSID'"; I will be using the value in a mathmatical problem later on, but for now I just want to print it out and I am unsure as to which variable to echo.

Multiple Result Sets With One Query
I need to query the DB and find records that coorespond to a given month and then display the data. $sql="select * from $tbl where month='january'"; ....... through december My question is this -> is it better to create 12 different queries or create one query and use an array (or somethiing else) to create basically 12 result sets? To me - 12 queries seems like it would be taxing on the db.
Moving A Query Result Into An Array
I have read all the array stuff done searches for examples, but am still not clear if there is a way to do a query from a MySQL table and move those vaules into an arry. I am sure it can be done, but I thought I would find a function that would do it. Am I just overlooking something? $resultID = mysql_query("SELECT DISTINCT slot FROM items"); while(list ($slot) = mysql_fetch_row($resultID)){echo"$slot";} So anyone have a good way to move the result into some array?
Strange Result From Table Query
I have a simple query that I am restricting to the first 4 character, however instead of the first 4 characters I am getting only the characters from the end of the field. The information in the field resembles: 4285-002 My result should be: 4285 What I am getting is: -002 The following is the code to pull the dat from field 'Dest': $dest=odbc_result($rs1, 'Destination'); $deststrcount=1; $deststr = $dest; $deststr = str_split($deststr,4); foreach($deststr as $destv){ if ($deststrcount<="1"){ $desttext=$destv; $destnew = "DEST[1,$deststrcount] $desttext"; $strcount=$strcount+1; }
Query Giving Array As Result
I just started PHP and getting the following error when trying to read and echo something from my DB. I get Array as an result of a working SQL query (I tested it in PHPMyAdmin SQL Query) and it should be something else.

Pulling Only 3 Digits From A Query Result Issues
I'm been playing with this for a few days and I can't seem to come close to getting this to work. Here is the situation. End users use their zip code to search for businesses. Well I want the search to show more then just what is in their zip code but really in their area. Easiest way I have found to do this is displaying all businesses that start with the same 3 digitals as their zip code. Example: there are businesses in Joplin, MO (64801) and in Neosho, MO (64850). When someone types in 64801 (Joplin) I want it to show the businesses in Neosho (64850) also.

PHP Update Query Mysql: Query Succussful?
I can't seem to successfully test an update query. Below is a piece of code that updates a statistics table. If row today doesn;t exist, a new day must be created.

MySQL Result Resource
I want to build a function that, depending on the input, will either return the results from a MySQL query or do something else and return one of several messages. My problem is checking the return value to see which is returned. Is there a php function that checks a variable to see if it is a valid MySQL result resource? I looked through the manual and couldn't find anything.

Returning 1 Result From MySQL
I know the usual way of receiving results from MySQL, useing a while loop e.g. $sql = "SELECT * FROM users WHERE email='joe@hotmail.com'"; $result = mysql_query($sql,$connection); while ($row = mysql_fetch_array($result)){ echo $row["firstname"]; echo $row["lastname"]; echo $row["email"];} BUT, if I know they only 1 result is going to be returned, is there a way to do this without using a while loop? So if I only wanted to get only the firstname of the person with email joe@hotmail.com. can I do this without a while loop or do I have to use one?

MySQL (DB) Result Sorting
I'm doing is taking results (fetching rows) from my mySQL database. But what I want to do is sort the results according to last name. So basically the table structure looks something like this: id (primary key) fullname A example rows could be: 1 John Smith 2 Mary Jane Now what I want to do is sort the results in PHP based on last name. I'm using the Pear DB for connecting to my mySQL database. Based on the example rows I gave, Mary Jane would go first, and then John Smith. How would I go about doing this? I was beginning to split the result based on spaces, and the last word to explode, but how would I truly do this?
Modifying MySQL Result - But Not The DB
How can I modify a MySQL data set returned by mysql_query? I am basically doing a while loop over the rows, changing one field, and then doing a mysql_data_seek back to the beginning of the set before returning it. However, later calls to mysql_fetch_assoc still return the orginal data, meaning that (I assume) I am changing a copy of the data rather than the result set itself. Taking the reference (i.e. $record =& mysql_fetch_assoc($result);) did not help. I have read a large quantity of the posts in the php.net site, googled, and read my PHP books - but have come up short on this one. Yes, I know it's better to simply modify the DB. However, I'm working with an existing code base which is very complicated, and want to cherry pick one very well tested feature by making a change in the result set only under special circumstances.

Result From Mysql Into Foreach?
when using mysql_fetch_array($result) I usually toss that into a while loop like so while($row = mysql_fetch_array($result)){ ... } however I was wondering if there was a way to put it in a foreach statement like so foreach(mysql_fetch_array($result) as $row){ ... } Is that legit? Will this work?
Linking To A MySQL Result
I had it the other day but now altered the code for my real database and it stopped working. Here is the first page which lists the 10 most recent news stories: <?php require ('get_connected.php'); $sql = mysql_query ("SELECT title, story_id FROM news ORDER BY story_id DESC LIMIT 0, 10"); while ($row = mysql_fetch_assoc($sql)){ echo "<a href='view.php?id={$row['story_id']}'>" . ucwords(strtolower($row['title'])) . "</a><br>"; } ?> And here is the page that should be displaying the news story based on story_id selected by the user.....
