• Storing an image map in a database

  - by ColoradoRockie

  I have a requirement to allow users in a content management system to create their own image maps through a gui interface, which I have accomplished. But instead of saving the image map to the page code, I want to save the image map code to a database (sql), which I've also accomplished. When I started down this road in my head I was thinking the whole time that I'd just add the "usemap" attribute at runtime shown below where promo1.ImageMap holds the entire map code: if(promo1.HasImageMap) imgPromotion1.Attributes.Add("usemap", promo1.ImageMap); I guess I didn't think it though well enough, because it seems that "usemap" only expects the name of the existing map to use from the page code, and not the map code as a string. Does anyone have any clever ideas on how to apply the map from the database to the image at run time?

• NHibernate: insert multiple items at once

  - by Gart

  Hello, all! I am learning NHibernate now and I would like to know is it possible to save multiple objects to database in one operation. For example, consider this test code private static void SaveTestBillNamesInSession(ISession session, params string[] names) { var bills = from name in names select new Bill { Name = name, DateRegistered = DateTime.Now, }; foreach (var bill in bills) session.SaveOrUpdate(bill); } This loop here generates many INSERT statements which may be sub-optimal in SQL Server 2008 which allows to include multiple data rows in one INSERT statement. Is it possible to rewrite this code to make use of this functionality - insert all the data in one operation?

• INSERT INTO temporary table from sp_executsql

  - by gotqn

  Generally, I am bulding dynamic SQL statement that is executing using sp_executsql like this: EXEC sp_executesql @TempSQLStatement I need to insert the return result row set in something (table variable or temporary table), but I am getting the following error: Msg 208, Level 16, State 0, Line 1746 Invalid object name '#TempTable'. after executing this: INSERT INTO #TempTable EXEC sp_executesql @TempSQLStatement From what I have read, I believe the issue is caused because I am not specifying the columns of the temporary table, but I am not able to do this because the return columns count varies. I have read that I can use global temporary tables, but I have done this before and wonder is there an other way to do that.

• How to get Screen Shot / Screen Capture from Web user on MVC site?

  - by RSolberg

  I've seen a few different apps that allow users to take screen shots on their PC and then the utility will automatically upload the image to the web server. I'd like to incorporate this type of functionality into a new MVC site. I could certainly just allow the user to upload their own image, but it'd be cleaner if they could click Capture Screen Shot and the image would be uploaded automatically. My team is using ASP.NET MVC2 with a SQL back end database. We are certainly willing to look into 3rd party components (activeX based, etc.) that will allow us to achieve this.

• Places to start for system programmer transitioning to web programming

  - by Sean Ochoa

  So here's where I'm coming from: My background is in C#, C++, VB Script, php, javascript, PowerShell, T-SQL, and VB 6. I have some experience with python, and a brief introduction to Ruby On Rails. At work, we're transitioning to a web based UI in the next year or so, but in asp.net & SilverLight. I would like to, if possible, learn more open source web technologies on the side. And, hopefully, in a year and a half or so, I would like to transition to a more open source web technology position. I found that I do really like python, but I'm open to pretty much anything. And yes, I do know Linux (ubuntu and gentoo), as well. And, here's my question: What technologies, frameworks, IDEs, or systems should I be highly proficient in to become a prime candidate for a position doing web application development using non-Microsoft technologies?

• adhoc struct/class in C#?

  - by acidzombie24

  Currently i am using reflection with sql. I find if i want to make a specialize query it is easiest to get the results by creating a new class inheriting from another and adding the 2 members/columns for my specialized query. Then due to reflections in the lib in my c# code i can write foreach(var v in list) { v.AnyMember and v.MyExtraMember) Now instead of having the class scattered around or modifying my main DB.cs file can i define a class inside a function? I know i can create an anonymous object by writing new {name=val, name2=...}; but i need a to pass this class in a generic function func(query, args);

• Extremely slow insert from Delphi to Remote MySQL Database

  - by MarkRobinson

  Having a major hair-pulling issue with extremely slow inserts from Delphi 2010 to a remote MySQL 5.09 server. So far, I have tried: ADO using MySQL ODBC Driver Zeoslib v7 Alpha I have used batching and direct insert with ADO (using table access), and with Zeos I have used SQL insertion with a Query, then used Table direct mode and also cached updates Table mode using applyupdates and commit. Both technologies I have tried with compression on and off. So far I have seen a pretty much the same across the board 7.5 records per second!!! Now, I would from this point assume that the remote server is just slow, but the MySQL Workbench is amazingly fast, and the Migration toolkit managed the initial migration very quickly (to be honest, I don't recall how quickly - which kind of means that it was quick) I'm just about to try the MyDAC components as we already use SDAC (wish there was a multi-buy discount or that we'd chosen UniDAC instead now!) Any ideas?

• Outlook Macro not executing

  - by Tim

  Hello all, we are using an an outlook macro for incoming emails to unzip the attachments, log them in sql server and copy them to a special working folder where a windows service processes them. The problems are: the user must be logged in at the server otherwise the macro wont run. I think there is no workaround for this. whenever a modal dialog pops up in outlook and waits for user input, the macro wont execute either (f.e. AutoArchive) I have stopped AutoArchiving all x-days in the options. Because its a productive environment, are there other possible windows preventing the macro to execute, which i must disable now? Our outlook-macro solution surely is not the best because of above problems. Are there better alternatives to read emails, unzip attachments and move them to a working folder? My language is VB.Net and server OS is windows 2008. Regards, Tim

• SEARCHING AND REPLACING BRACKETS IN A STRING IN ORACLE 10G

  - by Tunde

  hello, Thanks as usual for your prompt and kind suggestions. i am currently developing a function that is meant to execute dynamically created SQL statements. this is done by concatenating the columns and fetching them via cursors. the problem is that when there is a function with a comma between its arguments, the concat concatenates the contents of the functions inclusive. Is it possible to skip contents of every bracket found in a string using REGEXP_SUBTR or REGEXP_REPLACE? Many thanks for the anticipated response.

• How To Make NHibernate Automatically change an "Updated" column

  - by IanT8

  I am applying NHibernate to an existing project, where tables and columns are already defined and fixed. The database is MS-SQL-2008. NHibernate 2.1.2 Many tables have a column of type timestamp named "ReplicationID", and also a column of type datetime named "UpdatedDT". I understand I might be able to use the element of the mapping file to describe the "ReplicationID" column which will allow NHibernate to manage that column. Is it possible to make NHibernate automatically update the UpdatedDT column when the row is updated? I suppose I could try mapping the UpdatedDT property to be of type timestamp, but that have other side effects.

• Top techniques to avoid 'data scraping' from a website database

  - by Addsy

  I am setting up a site using PHP and MySQL that is essentially just a web front-end to an existing database. Understandably my client is very keen to prevent anyone from being able to make a copy of the data in the database yet at the same time wants everything publicly available and even a "view all" link to display every record in the db. Whilst I have put everything in place to prevent attacks such as SQL injection attacks, there is nothing to prevent anyone from viewing all the records as html and running some sort of script to parse this data back into another database. Even if I was to remove the "view all" link, someone could still, in theory, use an automated process to go through each record one by one and compile these into a new database, essentially pinching all the information. Does anyone have any good tactics for preventing or even just dettering this that they could share. Thanks

• VSTO: Attach meta-data to a cell in Excel?

  - by Gustav

  Hi! I'm using VSTO to create an Excel Add-on. This add-on retrieves and display alot of data from a sql-server. This works great, but later on I plan to access some of the data inside excel and modify it in some ways. My problem is that I need a way of classify cells that I want to modify. Is there any way to add meta-data to a cell to know if it is a cell that should be modified? E.g. add a attribute to the cell, e.g. "editable_cell", and do something like Excel.FindCellsWithAttribute("editable_cell") to find the sought after cells? Thanks! /Gustav

• Nhibernate: one-to-many, based on multiple keys?

  - by e36M3

  Lets assume I have two tables Table tA ID ID2 SomeColumns Table tB ID ID2 SomeOtherColumns I am looking to create a Object let's call it ObjectA (based on tA), that will have a one-to-many relationship to ObjectB (based on tB). In my example however, I need to use the combination of ID and ID2 as the foreign key. If I was writing SQL it would look like this: select tB.* from tA, tB where tA.ID = tB.ID and tA.ID2 = tB.ID2; I know that for each ID/ID2 combination in tA I should have many rows in tB, therefor I know it's a one-to-many combination. Clearly the below set is not sufficient for such mapping as it only takes one key into account. <set name="A2" table="A2" generic="true" inverse="true" > <key column="ID" /> <one-to-many class="A2" /> </set> Thanks!

• Getting a sorted distinct list from mySQL

  - by Stomped

  Goal I'l like to get a list of unique FID's ordered by the the one which has most recently been changed. In this sample table it should return FIDs in the order of 150, 194, 122 Example Data ID FID changeDate ---------------------------------------------- 1 194 2010-04-01 2 122 2010-04-02 3 194 2010-04-03 4 150 2010-04-04 My Attempt I thought distinct and order by would do the trick. I initially tried: SELECT distinct `FID` FROM `tblHistory` WHERE 1 ORDER BY changeDate desc # Returns 150, 122, 194 using GROUP BY has the same result. I'm just barely a SQL amateur, and I'm a bit hung up. What seems to be happening is the aggregating functions find the first occurrence of each and then perform the sort. Is there a way I can get the result I want straight from mySQL or do I have to grab all the data and then sort it in the PHP?

• SSIS - Update flag of selected rows from more than one table

  - by Rob Bowman

  Hi I have a SSIS package that copies data from table A to table B and sets a flag in table A so that the same data is not copied subsequently. This works great by using the following as the SQL command text on the ADO Net Source object: update transfer set ProcessDateTimeStamp = GetDate(), LastUpdatedBy = 'legacy processed' output inserted.* where LastUpdatedBy = 'legacy' and ProcessDateTimeStamp is not null The problem I have is that I need to run a similar data copy but from two sources table, joined on a primary / foreign key - select from table A join table B update flag in table A. I don't think I can use the technique above because I don't know where I'd put the join! Is there another way around this problem? Thanks Rob.

• Stored Procedure to create Insert statements in MySql ??

  - by karthik

  I need a storedprocedure to get the records of a Table and return the value as Insert Statements for the selected records. For Instance, The stored procedure should have three Input parameters... 1- Table Name 2- Column Name 3- Column Value If 1- Table Name = "EMP" 2- Column Name = "EMPID" 3- Column Value = "15" Then the output should be, select all the values of EMP where EMPID is 15 Once the values are selected for above condition, the stored procedure must return the script for inserting the selected values. The purpose of this is to take backup of selected values. when the SP returns a value {Insert statements}, c# will just write them to a .sql file. I have no idea about writing this SP, any samples of code is appreicated. Thanks..

• About sqlite use.

  - by rantravee

  Hi, There are some things my application needs to do on first start up(first startup after update) . These actions could be described in a .txt file and then when it is the case read the file and do according to it ,or on the other hand (I lean to use this option) a sqlite database could be used to store the information . The apk file would be shipped with an .txt file/prebuild sql db stored in res/raw or res.asset and then copied into proper space and used. This I have figured out how !, though I'm not sure which option of this two would be the fittest ? One thing that is unclear to me is how could sqlite version mismatch affect me, and if it serious enough to take into consideration ? I 'm using Android api level 4 (Android 1.6) and the future application might be used on several different devices , with different api levels.

• ASP.NET - Manual authentication system

  - by Gal V

  Hello all, Wer'e developing an ASP.NET C# application, which will contain an authentication system that authenticates users in multiple levels (user, admin, super-admin, etc.). Our idea is NOT to use the built in ASP.NET forms authentication feature. Our plan is to create a whole 'new' system for it- based on the Session object, and SQL database contains users' info such as username & password. Is there any SERIOUS different between our idea to the Forms authentication feature? What security risks do we take? How do we solve them? Is this a good alternative for the forms authentication feature? Thanks in advance !

• Mapped Stored Procedures in EF 1

  - by michael.lukatchik

  All, I'm using mapped Stored Procedures in EF 1. I've completed the following steps: 1) I've created my INSERT, UPDATE, and DELETE queries in SQL Server. 2) I've built the EDMX and imported the INSERT, UPDATE, and DELETE sprocs as part of my model. 3) I've set up a Stored Procedure Mapping on a table inside of my EDMX file. The INSERT, UPDATE, and DELETE sprocs were mapped accordingly. Using this approach, I would expect to rebuild the application (and mine builds successfully) and then see the Stored Procedures as available function names via my EDMX object, such as: _entities.InsertComment(..), _entities.UpdateComment(..), and _entities.DeleteComment(..) Intellisense is not picking these names up and I can't figure out why. If I perform these same steps using EF4, the function names are automatically picked up by Intellisense after adding the Stored Procedure Mappings. Is this a bug in EF1? Is there something else I should be doing? Thanks in advance, Mike

• MySQL: updating a row and deleting the original in case it becomes a duplicate

  - by Silvio Donnini

  I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

• not returning anything from postgresql function?

  - by netllama

  Is it possible for a PostgreSQL plpgsql function to not return anything? I've created a function, and I don't need it to return anything at all, as it performs a complex SQL query, and inserts the results of that query into another table (SELECT INTO ....). Thus, I have no need or interest in having the function return any output or value. Unfortunately, when I try to omit the RETURN clause of the function declaration, I can't create the function. Is it possible for a PostgreSQL plpgsql function to not return anything?
