• Kohana v3, automatically escape illegal characters?

  - by Dom

  Quick question, does Kohana (version 3) automatically escape data that is passed into ORM::factory..... (and everywhere else that has to do with the database)? For example: $thread = ORM::factory('thread', $this->request->param('id')); Would the data passed in the second argument be auto-escaped before it goes in the SQL query or do I have to manually do it? Probably a stupid question and it's better to be safe than sorry, but yeah... I usually do manually escape the data, but I want to know if Kohana does this for me? Thanks

• Correct sequence of actions when using Markdown & MySQL?

  - by Andrew Heath

  I want my users to be able to write an article in Markdown, have it stored in the MySQL database (with the option to edit it in the future), and displayed for other users. In practice, this is my understanding of how it works: INPUT user input via HTML form using Markdown syntax $queryInput = mysql_real_escape_string($userInput); insert sanitized string into database OUTPUT query field from database $output = Markdown($queryResult); display $output Is that it? Does PHP Markdown preclude the need for htmlspecialchars or Pure HTML ? Thanks!

• .NET SettingsProvider/ApplicationSettingsBase caching

  - by Andy White

  I'm looking at some code that uses the .NET System.Configuration.SettingsProvider and ApplicationSettingsBase to handle configuration. We have a class that derives from SettingsProvider that uses a database as the data store, and then we have other settings classes that inherit from ApplicationSettingsBase, and have the [SettingsProvider(typeof(MySettingsProvider))] attribute. The problem is that we're using these settings classes in multiple applications, but they seem to permanently cache the configuration values, the first time they are loaded. The issue is that if a setting is changed in one application, the other applications will not get the setting until the next restart, because they are cached everywhere. My question is: is there a way to force the SettingsProvider implementation, or the classes derived from ApplicationSettingsBase to not cache values, and re-query the datastore every time the setting is accessed? A valid answer might be that these classes were not intended to be used in multi-application environments...

• Last in First out UDP structure in MatLab.

  - by D Zondervan

  I am using MatLabs UDP function in their instrument control toolbox to send data packets from one computer to another. The first computer is constantly updating data values and sending them to the other computer, and I want that computer to be able to query the first one for the most recent values whenever it needs them. However, the default implementation of the UDP send and receive in MatLab is a FIFO structure- the first packet I send is the first the other computer receives when they execute the "fscanf" function. I want the last packet I sent to be the one the fscanf function returns. Is this possible or do I need to use a different protocol?

• MS Sql Full-text search vs. LIKE expression

  - by Marks

  Hi. I'm currently looking for a way to search a big database (500MB - 10GB or more on 10 tables) with a lot of different fields(nvarchars and bigints). Many of the fields, that should be searched are not in the same table. An example: A search for '5124 Peter' should return all items, that ... have an ID with 5124 in it, have 'Peter' in the title or description have item type id with 5124 in it created by a user named 'peter' or a user whose id has 5124 in it created by a user with '5124' or 'peter' in his street address. How should i do the search? I read that the full-text search of MS-Sql is a lot more performant than a query with the LIKE keyword and i think the syntax is more clear, but i think it cant search on bigint(id) values and i read it has performance problems with indexing and therefore slows down inserts to the DB. In my project there will be more inserting than reading, so this could be a matter. Thanks in advance, Marks

• Sharepoint Blog Category view - Pagination issue...

  - by hemalshah

  Folks, I am facing a rather strange issue. In my Sharepoint Blog, I am not able to view more than 10 posts when I click on the Category filter page. The page only shows the latest 10 posts and when I click on the pagination for the next 10, it simply says that "There are no posts in this category." I tried searching online and some one had a solution to it too, but that is with the Query String (URL) Filter which is not available in MOSS2007 Standard edition... How can I get around this? Any help would be greatly appreciated...

• can I run new WP_Query inside the Loop with no affects to the Loop? (wordpress)

  - by Radek

  the bellow function is working fine but I need to run it inside the loop. If done so the post content is actually taken from the last post of my WP_Query. Not from the one that should appear. Is there any way to run my query and leave The Loop unaffected? function recent_post_by_author() { echo '<div class="recent_post_by_author">'; $my_query = new WP_Query('author_name=Radek&showposts=2'); while ($my_query->have_posts()) : $my_query->the_post(); ?> <a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"> <?php the_title(); ?></a><BR> <?php endwhile; echo '</div>'; }

• Help Reading Binary Image Data from SQL Server into PHP

  - by Joe Majewski

  I cannot seem to figure out a way to read binary data from SQL server into PHP. I am working on a project where I need to be able to store the image directly in the SQL table, not on the file system. Currently, I have been using a query like this one: INSERT INTO myTable(Document) SELECT * FROM OPENROWSET(BULK N'C:\image.jpg', SINGLE_BLOB) as BLAH This works fine to actually insert the image into the table, but I haven't yet figured a way to retrieve it and get my image back. I am doing this with PHP, and ultimately will have to make a stored procedure out of it, but can anyone enlighten me on a way to get that binary data (varbinary(MAX)) and generate an image on the fly. I expected it to be simple to use a SELECT statement and add a content-type to the headers that indicated it was an image, but it's simply not working. Instead, the page will just display the name of the file, which I have encountered in the past and understand it to be an error with the image data.

• Writing a search engine

  - by wvd

  Hello all, The title might be a bit misleading, but I couldn't figure out a better title. I'm writing a simple search engine which will search on several sites for the specific domain. To be concrete: I'm writing a search engine for hardstyle livesets/aftermovies/tracks. To do I will search on the sites who provide livesets, tracks, and such. The problem here is speed, I need to pass the search query to 5-7 sites, get the results and then use my own algorithm to display the results in a sorted order. I could just "multithread" it, but it's easier said then done so I have a few questions. What would be the best solution to this problem? Should I just multithread/process this application, so I'm going to get a bit of speed-up? Are there any other solutions or I am doing something really wrong? Thanks, William van Doorn

• MySQL ignores the NOT NULL constraint

  - by Marga Keuvelaar

  I have created a table with NOT NULL constraints on some columns in MySQL. Then in PHP I wrote a script to insert data, with an insert query. When I omit one of the NOT NULL columns in this insert statement I would expect an error message from MySQL, and I would expect my script to fail. Instead, MySQL inserts empty strings in the NOT NULL fields. In other omitted fields the data is NULL, which is fine. Could someone tell me what I did wrong here? I'm using this table: CREATE TABLE IF NOT EXISTS tblCustomers ( cust_id int(11) NOT NULL AUTO_INCREMENT, custname varchar(50) NOT NULL, company varchar(50), phone varchar(50), email varchar(50) NOT NULL, country varchar(50) NOT NULL, ... date_added timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (cust_id) ) ; And this insert statement: $sql = "INSERT INTO tblCustomers (custname,company) VALUES ('".$customerName."','".$_POST["CustomerCompany"]."')"; $res = mysqli_query($mysqli, $sql);

• SQL Server (2005) Linked Server Issue

  - by David.Chu.ca

  I have SQL Server 2005 with several linked server defined. One of them is a connection to an Oracle server and another one is an ODBC bridge to another server on a remote machine (ODBC server). Recently I tried to use the linked server to Oracle to update data with two large size tables by using several joints. The update query took too long time and finally there was exception thrown: Update O set value = l.value FROM OracleServer..schema.largesizeTable O Join localLargeSizeTable l on .... The problem is that after the exception, I realized that another linked server to ODBC was not working any more. I had to restart SQL server to get the ODBC linked server back. It looks that the linked server pool could be crashed if any of them failed(not like sandbox in Chrome for each tab and no impact on other tabs or Chrome application at all). I am not sure if my assumption is correct or not. Is this a known issue of SQL server 2005?

• PHP / MySQL - How to retrieve 2 separate sets of objects?

  - by Dan

  Hi, I have a set of models which correspond to tables in my database. I have been retrieving them easily enough, for example. $result = $mysqli->query('SOME SQL'); $post = $result->fetch_object; What would be the best approach for performing a join and also returning the related objects? For example, each post is created by a user, so for each row returned in the joined statement, both a page and user object should be returned. Any advice appreciated. Thanks.

• SQL Server join and wildcards

  - by Ernst

  I want to get the results of a left join between two tables, with both having a column of the same name, the column on which I join. The following query is seen as valid by the import/export wizard in SQL Server, but it always gives an error. I have some more conditions, so the size wouldn't be too much. We're using SQL Server 2000 iirc and since we're using an externally developed program to interact with the database (except for some information we can't retrieve that way), we can not simply change the column name. SELECT table1.*, table2.* FROM table1 LEFT JOIN table2 ON table1.samename = table2.samename At least, I think the column name is the problem, or am I doing something else wrong?

  I have a table: mysql> desc kursy_bid; +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | datetime | datetime | NO | PRI | NULL | | | currency | varchar(6) | NO | PRI | NULL | | | value | varchar(10) | YES | | NULL | | +-----------+-------------+------+-----+---------+-------+ 3 rows in set (0.01 sec) I would like to select some rows from a table, grouped by some time interval (can be one day) where I will have the first row and the last row of the group, the max(value) and min(value). I tried: select datetime, (select value order by datetime asc limit 1) open, (select value order by datetime desc limit 1) close, max(value), min(value) from kursy_bid_test where datetime > '2009-09-14 00:00:00' and currency = 'eurpln' group by month(datetime), day(datetime), hour(datetime); but the output is: | open | close | datetime | max(value) | min(value) | +--------+--------+---------------------+------------+------------+ | 1.4581 | 1.4581 | 2009-09-14 00:00:05 | 4.1712 | 1.4581 | | 1.4581 | 1.4581 | 2009-09-14 01:00:01 | 1.4581 | 1.4581 | As you see open and close is the same (but they shouldn't be). What should be the query to do what I want?

• Correct Way to Get Date Between Dates In SQL Server

  - by Chuck Haines

  I have a table in SQL server which has a DATETIME field called Date_Printed. I am trying to get all records in the table which lie between a specified date range. Currently I am using the following SQL DECLARE @StartDate DATETIME DECLARE @EndDate DATETIME SET @StartDate = '2010-01-01' SET @EndDate = '2010-06-18 12:59:59 PM' SELECT * FROM table WHERE Date_Printed BETWEEN @StartDate AND @EndDate I have an index on the Date_Printed column. I was wondering if this is the best way to get the rows in the table which lie between those date or if there is a faster way. The table has about 750,000 records in it right now and it will continue to grow. The query is pretty fast but I'd like to make it faster if possible.
