• Connecting to MSSQL Express in silverlight 4 appl, the db doesn't shows up in Management Studio Expr

  - by Gabriel

  I'm using MSSQLExpress named instance in my Silverlight 4 application. The database located in the web application data folder. I attached the db via VS2010. The program works, but the db doesn't show up in Management Studio Express. If I delete the connection from within VS2010, and Try to attach to db via Management Studio Express, on writes, that the database with same the name already exists. Why the database connected via VS2010 doesn't show up in Management Studio Express? Thanks in advance Gabor

• introduce a join to this query, possible?

  - by Iain Urquhart

  I'm trying to introduce a join to this query: SELECT `n`.*, round((`n`.`rgt` - `n`.`lft` - 1) / 2, 0) AS childs, count(*) - 1 + (`n`.`lft` > 1) + 1 AS level, ((min(`p`.`rgt`) - `n`.`rgt` - (`n`.`lft` > 1)) / 2) > 0 AS lower, (((`n`.`lft` - max(`p`.`lft`) > 1))) AS upper FROM `exp_node_tree_6` `n`, `exp_node_tree_6` `p`, `exp_node_tree_6` WHERE `n`.`lft` BETWEEN `p`.`lft` AND `p`.`rgt` AND ( `p`.`node_id` != `n`.`node_id` OR `n`.`lft` = 1 ) GROUP BY `n`.`node_id` ORDER BY `n`.`lft` by adding LEFT JOIN `exp_channel_titles` ON (`n`.`entry_id`=`exp_channel_titles`.`entry_id`) after the FROM statement... But when I introduce it, it fails with "Unknown column 'n.entry_id' in 'on clause'" Is it even possible to add a join to this query? Can anybody help, thanks!

• Ant database rebuild script, avoiding interactive prompting

  - by fras85

  Hi Guys. I'm writing an ant script to rebuild our database i.e. dropping everything and rebuilding from scratch. The problem our DBA adds a Y/N prompt before executing the rest of the script, and therefore we can't call this from an automated build process. Does anyone have any suggestions to circumvent the Y/N prompt? Obviously we could create seperate scripts, one for the DBA's and one for the automated build - but this requires maintaning both. We're running on Windows so it's not as easy as using sed to strip out the prompt...but i'm thinking something along those lines. Not sure if that's clear enough but hope you can help. Cheers.

• Help with a MySQL SELECT WHERE Clause

  - by Dr. DOT

  A column in my table contains email addresses. I have a text string that contains the a few usernames of email addresses separated by commas. I can make text sting into an array if necessary to get my SELECT WHERE clause to work correctly. Text string search argument is 'bob,sally,steve' I want to produce a WHERE clause that only returns rows where the username portion of the email address in the table matches one of the usernames in my text string search argument. Thus a row with [email protected] would not be returned but [email protected] would be. Does anyone have a WHERE clause sample that produces this result? Thanks.

• How do I properly use LINQ with MySQL?

  - by Arda Xi

  I've been looking this up on Google for hours, but I haven't found anything conclusive. So far, I've seen a few paid options, an option with NHibernate, but most are marked as unstable or in production. Is there a stable implementation of LINQ for MySQL?

• CakePHP adding columns to a table

  - by vette982

  I have a Profile model/controller in my cake app as well as an index.ctp view in /views/profiles. Now, when I go to add a column to my table that is already filled with data, and then add the corresponding code to the view to pick up this column's data, it just gives me an empty result. My model: <?php class Profile extends AppModel { var $name = 'Profile'; } ?> My controller: <?php class ProfilesController extends AppController { var $name = 'Profiles'; function index() { $this->set('profiles', $this->Profile->find('all')); } } ?> My views printing (stripped down): <?php foreach ($profiles as $profile): ?> <?php echo $profile['Profile']['id']; ?> <?php echo $profile['Profile']['username']; ?> <?php echo $profile['Profile']['created']; ?> <?php echo $profile['Profile']['thumbnail'];?> <?php echo $profile['Profile']['account'];?> <?php endforeach; ?> Basically, the columns id, username, column, thumbnail always have been printing fine, but when I add a column called accountit returns no information (nothing prints, but no errors). Any suggestions?

• Sanitizing DB inputs with XSLT

  - by azathoth

  Hello I've been looking for a method to strip my XML content of apostrophes (') like: <name> Jim O'Connor</name> since my DBMS is complaining of receiving those. By looking at the example described here, that is supposed to replace ' with '', I constructed the following script: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*" /> </xsl:copy> </xsl:template> <xsl:template name="sqlApostrophe"> <xsl:param name="string" /> <xsl:variable name="apostrophe">'</xsl:variable> <xsl:choose> <xsl:when test="contains($string,$apostrophe)"> <xsl:value-of select="concat(substring-before($string,$apostrophe), $apostrophe,$apostrophe)" disable-output-escaping="yes" /> <xsl:call-template name="sqlApostrophe"> <xsl:with-param name="string" select="substring-after($string,$apostrophe)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string" disable-output-escaping="yes" /> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="node()|@*"> <xsl:apply-templates name="sqlApostrophe"/> </xsl:template> </xsl:stylesheet> However, the processor isn't accepting it. What am I missing here? Is there a better way to get rid of the apostrophes? Perhaps another approach for sanitizing DB inputs by using XSLT? Thanks for your help

• PHP 'smart' search engine to search Mysql tables advice

  - by Anonymous12345

  I am creating a search engine for my php based website. I need to search a mysql table. Thing is, the search engine must be pretty 'smart', so that users can easily find their items (it's a classifieds website). I have currently set up a FULLTEXT search with this piece of code: MATCH (headline) AGAINST ($querystring) But this isn't enough... For instance, lets say the field headline contains something like Bmw 330ci. If I search for 330, I wont get any results. The ending ('ci') is just one of many endings in car models which must be taken into account when searching the table. Or what if the headline field is bmw330? Also no results, because it only matches full words. Or also, what if the headline is bmw 330, and I search for bmw 520, still with FULLTEXT I will get the bmw 330 as a result, even though I searched for bmw 520... Not good! How should I solve this problem?

  - by Swoosh

  I have a stored procedure which is doing a lot of delete. Hundreds of thousands of records. It is not going to be runnable from the application, but still, i am concerned, that one of my clients accidentally runs it (i had problems earlier due to their "curiosity") :D Yes. there are backups and stuff like that, but I was thinking .... not to scare them ... is there a way to ask the user "are you sure?" before executing it? :) thanks

• How to generate a transaction number?

  - by 001

  I was thinking of formatting it like this TYYYYMMDDNNNNNNNNNNX (1 character + 19 digits) Where T is type YYYY is year MM is month DD is day N is sequencial number X is check digit The problem is, how do I generate the sequencial number? since my primary key is not an auto increment integer value, if it was i would use that, but its not. EDIT can I have the sequencial number resets itself after 1 day (24hours). P201012080000000001X <-- first transaction of 2010/12/08 P2010120810000000002X <--- second transaction of 2010/12/08 P201012090000000001X <--- First transaction of 2010/12/09 (X is the check digit)

• SQLite - ON DUPLICATE KEY UPDATE

  - by Alix Axel

  MySQL has something like this: INSERT INTO visits (ip, hits) VALUES ('127.0.0.1', 1) ON DUPLICATE KEY UPDATE hits = hits + 1; As far as I'm know this feature doesn't exist in SQLite, what I want to know is if there is any way to archive the same effect without having to execute two queries. Also, if this is not possible, what do you prefer: SELECT + (INSERT or UPDATE) or UPDATE (+ INSERT if UPDATE fails)

• MSSQL 2005 FOR XML

  - by Lima

  Hi, I am wanting to export data from a table to a specifically formated XML file. I am fairly new to XML files, so what I am after may be quite obvious but I just cant find what I am looking for on the net. The format of the XML results I need are: <data> <event start="May 28 2006 09:00:00 GMT" end="Jun 15 2006 09:00:00 GMT" isDuration="true" title="Writing Timeline documentation" image="http://simile.mit.edu/images/csail-logo.gif"> A few days to write some documentation </event> </data> My table structure is: name VARCHAR(50), description VARCHAR(255), startDate DATETIME, endDate DATETIME (I am not too interested in the XML fields image or isDuration at this point in time). I have tried: SELECT [name] ,[description] ,[startDate] ,[endTime] FROM [testing].[dbo].[time_timeline] FOR XML RAW('event'), ROOT('data'), type Which gives me: <data> <event name="Test1" description="Test 1 Description...." startDate="1900-01-01T00:00:00" endTime="1900-01-01T00:00:00" /> <event name="Test2" description="Test 2 Description...." startDate="1900-01-01T00:00:00" endTime="1900-01-01T00:00:00" /> </data> What I am missing, is the description needs to be outside of the event attributes, and there needs to be a tag. Is anyone able to point me in the correct direction, or point me to a tutorial or similar on how to accomplish this? Thanks, Matt

• DataSet with many OR clauses

  - by Silvan

  Hello :) I've got a little problem with a query which I create in the Visual Studio Designer. I need a query with a lot of 'OR'-clauses for the same column. I found the operator 'IN', but I don't know how to use that in the Visual Studio Designer: Example IN: SELECT EmployeeID, FirstName, LastName, HireDate, City FROM Employees WHERE City IN ('Seattle', 'Tacoma', 'Redmond') I tried to do it in this way: SELECT [MachineryId], [ConstructionSiteId], [DateTime], [Latitude], [Longitude], [HoursCounter] FROM [PositionData] WHERE [MachineryID] IN @MachineryIDs But this doesn't work. Is there another way to handle a lot of OR clauses? Thank you very much for your help.

• Multiple LIKE in SQL

  I wanted to search through multiple rows and obtain the row that contains a particular item. The table in mySQL is setup so each id has a unique list (comma-delimited) of values per row. Ex: id | order 1 | 1,3,8,19,34,2,38 2 | 4,7,2,190,38 Now if I wanted to pull the row that contained just the number 19 how would I go about doing this?
