It's written in PHP,
and sometimes when I restart mysql,
will report:
Debug Warning:line 24 - mysql_fetch_array(): supplied argument is not a valid MySQL result resource
Is there any way to detect if $result is a valid MySQL result resource?

Answer Snippets (Read the full thread at stackoverflow):
Mysql_error(); }
Or you could just do:
if ($result) { $row = mysql_fetch_array($result); // Do everything....
If ($result) { $row = mysql_fetch_array($result); } else { echo "MySQL error: " .
It'll be false if there's an error.

When I have something like this:
$row = mysqli_fetch_assoc($result);
Does $result now have one less row in it? If I loop mysqli_fetch_assoc through all the $result , will it be empty afterwards?

The manual page provides additional info.
The result as such is untouched.
It will give you a result and internally move on to the next record.
result is a resource pointer , it is not possible to add to, or remove data from it.

Why does mysql_num_rows($result) return 1 even if $result returns empty result set?
$resut=mysql_query("select * from tablename where column1='$memberid' and (TIME_TO_SEC(TIMEDIFF(NOW(),when_submit))/60<2)")or die(mysql_error()); $count=mysql_num_rows...

$result....
That should be $result, since that is what you are passing in the call to different $result variables.
You store the result of the call to mysql_query() in the variable called $resut.
You have a spelling error in your code.

I'v run both commands and they both seem to do the same thing, is this true or is there something happening I'm not seeing?
These two appear to do the same thing:
result=$(ls -l) result=`ls -l`

The $() syntax is a bit more permissive in what can go between the () as compared to what is accepted between `` .

FOR EACH result $result = "Something something hello there yes world fun nice"; $highlighted = preg_replace($regex, '<strong>$0</strong>', $result);
If you are using PostgreSQL, you can.

I think this might be more accurately called "paging"... not sure. I am getting a chunk of XML (lets say 100 nodes) I then want to display only a set number of them at a time on a page. How do you do this?
For reference, in .NET it would be something ...

Xpath returns an array of SimpleXMLElement objects, so you could do something like:
$result = $xml sure that $result[$i] exists // Then handle printing $result[$i] }.

Hi,
I am using JMeter and have 2 questions (I have read the FAQ + Wiki etc):
I use the Graph Results listener . It seems to have a fixed span, e.g. 2 hours (just guessing - this is not indicated anywhere AFAIK), after which it wraps around and starts ...

You can use the Simple Data Writer to store results efficiently for later analysis.
Regarding 2: listeners typically have a configuration field for "Write All Data to a File", which lets you specify the file name .
Don't know about 1.

Hi, I have a DB table with approx. 100,000 entries.
My web app will show paged results of search queries, which may yield between 0 and 100,000 records.

QUite a number of paging related posts in SO here .
Depending on the count value, you can then decide your retrieval/paging strategy .
You can get the count first by running a seperate query, without retrieving all other table columns .

It may be different than your local .testrunconfig.
Check that the .testrunconfig used by the server has coverage enabled .

Then sort as follows:

This of course assumes that your ... .
Special doesn't necessarily have to actually exist in the table, you can derive it the query however you see fit .
You could add an addition field called 'Special'.
