• How to automatically change a parameter in Reporting Services when another is changed?

  - by Victor Rodrigues

  I have a 'Product' parameter in my report. Depending on the product the user chooses, it will call the report generator stored procedure from a different data source. Looking at this article, I've found how to do the first part of this solution. I've created two internal parameters, Server and Database, and the connection string will use them to connect to the right database. But I need to set this two parameters when the user chooses a product. How could I do this? (If @Product = X) = @Server = Y, @Database = Z

• Backing up MySQL DB wtih mixture of innodb and myisam tables

  - by madphp

  I have a large database (almost 1GB) and it has a mixture of innodb and myisam tables. Does anyone have any general tips when backing it up or more specifically the commands i should send to mysqldump. I see that i should lock myisam tables, and that single transactions for innodb, but what if i have both. Also, what is actually happening when i lock an entire (very big) table on a production database.

• at what point in the test cycle are the test results written to a file?

  - by jcollum

  I'd like to take the entirety of the test results and publish it to a database. Got the database, got the table, got the script to publish it. Question is, at what point in the ms-test cycle would the results be fully written to the file? And how can I get the path to that file? I'd especially like to grab the "TextMessages" node and put it into my database. I assumed AssemblyCleanup, but the TestContext doesn't seem to be available then.

• How to change a Datasource's username/password at runtime in a J2EE app?

  - by Toto

  I've deployed a web-module which connects to the database via a datasource configured in the J2EE application server. Currently, the user/password for the database connection is set in the proper J2EE application server's datasources configuration file. I want to change during runtime the datasource's user/password. (e.g.: implement a new web form in which the user is asked to enter de user/password to be used in the database connection). Is there a standard way to do that in J2EE applications or it depends on the J2EE application server? In this case I'm using Orion application server.

• Best practice. Do I save html tags in DB or store the html entity value?

  - by Matt

  Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should I encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but I'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, I'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, I just wondered on what you guys thought.

• updating batches of data

  - by gaponte69

  I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...

• Dollar ($) sign in password string treated as variable

  - by ncatnow

  Spent some time troubleshooting a problem whereby a PHP/MySQL web application was having problems connecting to the database. The database could be accessed from the shell and phpMyAdmin with the exact same credentials and it didn't make sense. Turns out the password had a $ sign in it: $_DB["password"] = "mypas$word"; The password being sent was "mypas" which is obviously wrong. What's the best way to handle this problem? I escaped the $ with a \ $_DB["password"] = "mypas\$word"; and it worked. I generally use $string = 'test' for strings which is probably how I avoided running into this before. Is this correct behavious? What if this password was stored in a database and PHP pulled it out - would this same problem occur? What am I missing here...

• Schema changes with replication

  - by Even Mien

  What are the steps to make a schema change to a SQL Server 2005 database using transactional replication? I'm trying to add a database column. I thought if I removed the article for the table, made the schema change, and then added the article for the table back that the schema change would replicate. I am now getting the following error every minute or so: SQL Server errors Replication-Replication Distribution Subsystem: agent [jobname] failed. Invalid column name 'NewColumn'.

• Idiomatic way to read .env variables in Ansible?

  - by Arms

  I'm provisioning a Vagrant box with Ansible, and using Benno Joy's MySQL role to setup MySQL (including creating a database and users.) The database name and credentials are stored in a .env file in the project's root. What would be the idiomatic way to use these variables when provisioning MySQL? Should I write a custom script that generates a YAML file from my .env, and then use the include_vars module? Or is there a simpler way?

• Excel File opened under Ubuntu, read by R, OpenOffice

  - by Vishal Belsare

  I have a bunch of Excel files which are updated on a daily basis on a Windows machine. I transfer them to a Ubuntu machine and want to open them there. Specifically, I want to read the files as a database under R. A couple years ago, I used ODBC under a Windows machine to open Excel files through R. Is there any way, I can do this with R under Ubuntu? I could make a database .ODB file for the corresponding XLS files using OpenOffice, but I don't know of a way to connect to a .ODB database. OpenOffice seems to have ways to connect TO databases, but no way to connect to ODB. Thanks for any potential solutions.

• How to programmatically change a data cell of Ms Access using VB.Net?

  - by manuel

  I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = textbox.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Low". What codes should I put in the button_Click event handler? Here is the codes I used to retrieve and display the database table. Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub

• ASP.NET MVC User authentication - why it should be so sophisticated?

  - by Serge

  Hello guys, I'm trying to use ASP.NET MVC to my new project and have been expected that the user authentication should be rather simple there. My goal is to have a separate user database table in my main database. I thought that the SqlTableProfileProvider should be the solution. So I added the corresponding table into my database and changed the web.config file. But it seems no matter what I change there, my web application still using the default authentication (via ASPNETDB.mdf file). What could be the problem? (my web.config file beginning is:)

• Reading Character from Image

  - by Chinjoo

  I am working on an application which requires matching of numbers from a scanned image file to database entry and update the database with the match result. Say I have image- employee1.jpg. This image will have two two handwritten entries - Employee number and the amount to be paid to the employee. I have to read the employee number from the image and query the database for the that number, update the employee with the amount to be paid as got from the image. Both the employee number and amount to be paid are written inside two boxes at a specified place on the image. Is there any way to automate this. Basically I want a solution in .net using c#. I know this can be done using artificial neural networks. Any ideas would be much appreciated.

• SqlBulkCopy unusual TimeOut Error

  - by ChrisHDog

  I have a SqlBulkCopy operation that is taking data from an MS-Access 2007 database (via OleDbConnection) and using SqlBulkCopy to transfer that data to a SQL Server database. This has previously been working and continues to work for one MS-Access database, but not the other. I get the error message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It is hard to believe it is a timeout ast the oledbCommand.CommandTimeout = 0 the sqlBulkCopy.BulkCopyTimeout = 0 and on either side (MS-Access and SQL Server the timeouts have now been set to 0). Are there other issues/exceptions that the above error message could be hiding? Is there a way to determine what the base cause of a sqlBulkCopy.WriteToServer exception is (there doesn't appear to be any inner exceptions etc...)

• ASP.NET handling button click event before OnPreInit

  - by Phillykins

  Hello, I have a data access layer, a business logic layer and a presentation layer (ie. the pages themselves). I handle the OnPreInit event and populate collections required for the page. All the data comes from an SQL server database and I do not use caching. I handle a button click event to grab values from a form and insert a new object into the database. The problem is that by the time I handle the click event, the collections have already been populated, so the new item which has been inserted into the database has not been retrieved. What is the accepted solution to this? I could insert the new object directly into the collection and re-bind the GridView, but the SQL query selects only a set of objects and the new object could fall outside of this set. Thanks!

• Syncing with Address Book: Last modified property in ABPerson/ABRecord

  - by Oliver

  I'm syncing data from the Address Book into a Core Data database and I've nearly got it working perfectly. The only issue remaining is checking for changes and modifications on startup and reflecting the changes inside Core Data. Currently, I simply check the ID of each ABRecord and see if it is already in Core Data. Of course, this only works in the case of new contacts and not changed information inside an existing contact. One solution would be to go through each contact already in the database and check each property against the Address Book. The down side of this is that it's really slow. One method that would work is if the ABRecord had a last modified date. I could then store the date inside the Core Data database and check on startup to see if I need to update the contact. However, I can't find anything like this in the documentation. Any ideas?

• Need to map classes to different databases at runtime in Hibernate

  - by serg555

  I have MainDB database and unknown number (at compile time) of UserDB_1, ..., UserDB_N databases. MainDB contains names of those UserDB databases in some table (new UserDB can be created at runtime). All UserDB have exactly the same table names and fields. How to handle such situation in Hibernate? (database structure cannot be changed). Currently I am planning to create generic User classes not mapped to anything and just use native SQL for all queries: session.createSQLQuery("select * from " + db + ".user where id=1") .setResultTransformer(Transformers.aliasToBean(User.class)); Is there anything better I can do? Ideally I would want to have mappings for UserDB tables and relations and use HQL on required database.

• PHP auto refresh page without losing user input

  - by Tony

  I'm working on a PHP collaboration software project. I have a page that shows the latest updates from other users who are adding content to the database, but also has a form input to allow the user to enter text. I am currently using this code to refresh the page automatically every 30 seconds: header('Refresh: 30'); The problem is that the header code refreshes the entire page, and not just what is pulled from the database. Is there any PHP code that will just pull any new data from the database without refreshing the entire page? If someone could point me in the right direction I'd appreciate it.
