  • PHP: Simulate multiple MySQL connections to same database

    - by Varun
    An insert query is constantly getting logged in my MySQL slow query log. I want to see how much time the INSERT query is taking with 100 simultaneous insert operations(to the same table). So I need to simulate the follwoing. 500 different simultaneous connections from PHP to the same database on a mysql server, all of which are inserting a row(simultaneously) to the same table. DO I need to use any load testing tool? Or Can I simply write a PHP script to do this? Any thoughts?

  • Insert into ... Select *, how to ignore identity?

    - by Haoest
    I have a temp table with the exact structure of a concrete table T. It was created like this: select top 0 * into #tmp from T After processing and filling in content into #tmp, I want to copy the content back to T like this: insert into T select * from #tmp This is okay as long as T doesn't have identity column, but in my case it does. Is there anyways I can ignore the auto-increment identity column from #tmp when I copy to T? My motivation is to avoid having to spell out every column name in the Insert Into list. EDIT: toggling identity_insert wouldn't work because the pkeys in #tmp may collide with those in T if rows were inserted into T outside of my script, that's if #tmp has auto-incremented the pkey to sync with T's in the first place.

  • Rails: Best practice to store user settings?

    - by ole_berlin
    Hi, I'm wondering what the best way is to store user settings? For a web 2.0 app I want users to be able to select certain settings. At the moment is it only when to receive email notifications. The easiest way would be to just create a Model "Settings" and have a column for every setting and then have a 1-1 relationship with users. But is there a pattern to solve this better? Is it maybe better to store the info in the user table itself? Or should I use a table with "settings_name" and "settings_value" to be completely open about the type of settings stored there (without having to run any migrations when adding options)? What is your opinion? Thanks

  • How to prevent CAST errors on SSIS ?

    - by manitra
    Hello, The question Is it possible to ask SSIS to cast a value and return NULL in case the cast is not allowed instead of throwing an error ? My environment I'm using Visual Studio 2005 and Sql Server 2005 on Windows Server 2003. The general context Just in case you're curious, here is my use case. I have to store data coming from somewhere in a generic table (key/value structure with history) witch contains some sort of value that can be strings, numbers or dates. The structure is something like this : table Values { Id int, Date datetime, -- for history Key nvarchar(50) not null, Value nvarchar(50), DateValue datetime, NumberValue numeric(19,9) } I want to put the raw value in the Value column and try to put the same value in the DateValue column when i'm able to cast it to Datetime in the NumberValue column when i'm able to cast it to a number Those two typed columns would make all sort of aggregation and manipulation much easier and faster later. That's it, now you know why i'm asking this strange question. ============ Thanks in advance for your help.

  • how do I do this UPDATE in sqlite?

    - by Jason S
    I have a table assoc containing columns local_id, remote_id, cachedData I can successfully run an SQLITE query that looks like SELECT a1.local_id, a1.remote_id FROM assoc a1 LEFT JOIN .... so that I identify certain rows of the assoc table that meet my criteria. What I would like to do is to set cachedData to null in those rows. How can I do this? Sqlite doesn't support UPDATE with joins; you can issue subqueries but I can't figure out how to get the syntax correct; it seems nonintuitive to me.

  • highlight search keywords on hover

    - by fusion
    i've a basic php search form which highlights the keywords using css. i was wondering if i could make the keywords in the results highlight only when the user hovers over the record. is this possible? this is the highlight code: function highlightWords($text, $words) { preg_match_all('~\w+~', $words, $m); if(!$m) return $text; $re = '~\\b(' . implode('|', $m[0]) . ')~i'; $string = preg_replace($re, '<span class="highlight">$0</span>', $text); return $string; } . . . <table class="result"> <?php while ($row= mysql_fetch_array($result, MYSQL_ASSOC)) { $cQuote = highlightWords(htmlspecialchars($row['cQuotes']), $search_result); ?> <tr> <td style="text-align:right; font-size:15px;"><?php h($row['cArabic']); ?></td> <td style="font-size:16px;"><?php echo $cQuote; ?></td> <td style="font-size:12px;"><?php h($row['vAuthor']); ?></td> <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']); ?></td> </tr> <?php } ?> </table> css: table.result tr:hover { background:#F7F7F7; } .highlight { font-weight:bold; color: #DE2842; padding:5px; padding-right:2px; background: #FFFCDB; } i tried changing the color through highlight:hover, but this changed the color of the search keyword only when i hovered over the keyword itself, which is understandable since that's the way it is supposed to work, but i'd like the search keywords to be highlighted when i hover over the result as a whole.

  • UITableViewCell height with 0 rows

    - by Typeoneerror
    I've got a moderately uncustomized UITableView in my application that presents an array of up to 6 peers for a networking game. When no peers are found the numberOfRowsInSection is 0, so when it loads up, there's no rows in the table: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 0; } Trouble is, the height of each cell is not adjusted to match heightForRowAtIndexPath unless the numberOfRowsInSection is 0. I hard-coded in "1" for this and the height is adjusted. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return kTableRowHeight; } Can anyone tell me why this is? Will once the data that is being presented is longer than "0" length, will the height of the table cells jump to the correct height? I'd like them to be the correct height even if the row length is 0.

  • How to show related content using like in mysql?

    - by halocursed
    I currently have a table for products with it's own set of tags and a table for news with it's own set of tags. I wanted to add related news to the products page so I was thinking of using like but since the column tags in the products page is something like (Products) tags- manutd, man utd, football (news) tags - manutd, blah, bruha [this one is related] (news) tags - man, utd, bruha [this one is not related] I wanted to use a query to show all news containing any of the tags(from products) seperated by commas using mysql. How should I go about constructing such a query? If there is a better way of doing this a little explanation would be helpful too. Thanks

  • index seems to be out of sync for jquery .keydown and .click methods

    - by Growler
    I'd like to navigate images using both keyboard and mouse (clicking left and right arrow images). I'm using Jquery to do this, but the shared imgIndex seems to be off from the .keydown function and the .click function... Whenever .keydown function -- or ++ the imgIndex, isn't that changed index also used in the click function? So shouldn't they always be on the same index? keydown function: <script type="text/javascript"> var imgArray = [<?php echo implode(',', getImages($site)) ?>]; $(document).ready(function() { var img = document.getElementById("showimg"); img.src = imgArray[<?php echo $imgid ?>]; var imgIndex = <?php echo $imgid ?>; alert(imgIndex); $(document).keydown(function (e) { var key = e.which; var rightarrow = 39; var leftarrow = 37; var random = 82; if (key == rightarrow) { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; } if (key == leftarrow) { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; } }); click function: Connected to left and right clickable images $("#next").click(function() { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; }); $("#prev").click(function() { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; }); }); Just so you have some visibility into the getImages php function: <?php function getImages($siteParam) { include 'dbconnect.php'; if ($siteParam == 'artwork') { $table = "artwork"; } else { $table = "comics"; } $catResult = $mysqli->query("SELECT id, title, path, thumb, views, catidFK FROM $table"); $img = array(); while($row = $catResult->fetch_assoc()) { $img[] = "'" . $row['path'] . "'"; } return $img; } ?> Much appreciated! Snapshot of where the script is on "view image.php"

  • Anyone using a web service as a data source in Excel 2007?

    - by Scott
    Can I use a web service as a data soruce for Excel pivot tables? Currently, the soure data for the pivot table is being exported from the DB to a CSV file. Then the CSV file is loaded into a worksheet in the workbook. From there, a pivot table is created in the same workbook. We are looking to streamline this process. The SQL db and pivot tables are the constants. The pivot tables are generated dynamically from a public-facing website. This is not an internal app so the preference is to not connect directly to the DB.

  • Selecting a sequence NEXTVAL for multiple rows

    - by stringpoet
    I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

  • Return segmented average from SQL Query?

    - by Guillaume Filion
    Hi, I measure the load on DNS servers every minute and store that into an SQL DB. I want to draw a chart of the load for the last 48 hours. That's 69120 (48*24*60) data points but my chart's only 800 pixels wide so to make things faster I would like my SQL query to return only ~800 data points. It's seems to me like a pretty standard thing to do, but I've been searching the web and in books for such a thing for a while now and the closest I was able to find was a rolling average. What I'm looking for a more of a "segmented average": divide the 69120 data points in ~800 segments, then average each segment. My SQL table is: CREATE TABLE measurements ( ip int, measurement_time int, queries int, query_time float ) My query looks like this SELECT ip, queries FROM measurements WHERE measurement_time>(time()-172800) Thanks a lot!

  • Complicated Order By Clause?

    - by Todd
    Hi. I need to do what to me is an advanced sort. I have this two tables: Table: Fruit fruitid | received | basketid 1 20100310 2 2 20091205 3 3 20100220 1 4 20091129 2 Table: Basket id | name 1 Big Discounts 2 Premium Fruit 3 Standard Produce I'm not even sure I can plainly state how I want to sort (which is probably a big part of the reason I can't seem to write code to do it, lol). I do a join query and need to sort so everything is organized by basketid. The basketid that has the oldest fruit.received date comes first, then the other rows with the same basketid by date asc, then the basketid with the next earliest fruit.received date followed by the other rows with the same basketid, and so on. So the output would look like this: Fruitid | Received | Basket 4 20091129 Premuim Fruit 1 20100310 Premuim Fruit 2 20091205 Standard Produce 3 20100220 Big Discounts Any ideas how to accomplish this in a single execution?

  • Best way to move a bunch of SQL Server 2005 tables to another Server?

    - by Mikecancook
    I've been looking for a way to move a bunch of tables, more than 40, to another server with all the data in them. I've looked around for scripts to generate inserts but so far I'd have to run them once for every table, then copy all the scripts over and then run them on the server. Seems like there is a better way. --Update-- My strategy for doing this may have been for naught. The end script, using MS SQL Server Publishing Wizard and Red Gates SQL Data Compare (excellent tool, btw) results in a file over 1GB. This makes my system plead for mercy and I'm not willing to risk crashing a clients server just opening the file to run it. I may have to rethink this whole thing and break down to just individual per table scripts. I'm not looking forward to that.

  • Alternative to slip string in this scenario?

    - by MEM
    I have the following information to dynamicaly display: Product XYZ Very nice Very good Very cool Those Very nice, very good, very cool are advantages of a given product, textual, description advantages, normally display in a form of bullets. I guess that it makes no sense to store those on a separate table called advantages, because it will never be used to anything else despite display, and I fill it as too overkill. So I was thinking about creating a varchar255 field on this product table, and allow values to be inserted like: Very nice;Very good;Very cool On a free-form text input field. Then split those on a php array. My question is: Is it out there, a better approach ?

  • Unexpected behaviour of Order by clause(SQL SERVER 2005)

    - by Newbie
    I have a table which looks like Col1 col2 col3 col4 col5 1 5 1 4 6 1 4 0 3 7 0 1 5 6 3 1 8 2 1 5 4 3 2 1 4 The script is declare @t table(col1 int, col2 int, col3 int,col4 int,col5 int) insert into @t select 1,5,1,4,6 union all select 1,4,0,3,7 union all select 0,1,5,6,3 union all select 1,8,2,1,5 union all select 4,3,2,1,4 If I do a sorting (ascending), the output is Col1 col2 col3 col4 col5 0 1 5 6 3 1 4 0 3 7 1 5 1 4 6 1 8 2 1 5 4 3 2 1 4 The query is Select * from @t order by col1,col2,col3,col4,col5 But as can be seen that the sorting output is wrong (col2 to col5). Why so and how to overcome this? Thanks in advance

  • How should I do this (business logic) in Sql Server? A constraint?

    - by Pure.Krome
    Hi folks, I wish to add some type of business logic constraint to a table, but not sure how / where. I have a table with the following fields. ID INTEGER IDENTITY HubId INTEGER CategoryId INTEGER IsFeatured BIT Foo NVARCHAR(200) etc. So what i wish is that you can only have one featured thingy, per articleId + hubId. eg. 1, 1, 1, 1, 'blah' -- Ok. 2, 1, 2, 1, 'more blah' -- Also Ok 3, 1, 1, 1, 'aaa' -- constraint error 4, 1, 1, 0, 'asdasdad' -- Ok. 5, 1, 1, 0, 'bbbb' -- Ok. etc. so the third row to be inserterd would fail because that hub AND category already have a featured thingy. Is this possible?

  • Convert hex to decimal keeping fractional part in Lua
