I am trying to truncate one of our tables in a class to run as a batch job, but keep getting a "Request for permission of type SqlDataDictionaryPermission failed. This is on an AX 4.0 system. I followed MSDN example on acquiring permissions and I am an admin. Here's the code:
//Truncate table
new SqlDataDictionaryPermission(
methodstr(SqlDataDictionary, tableTruncate)).assert();
sqlDict = new SqlDataDictionary();
sqlDict.tableTruncate(tableNum(PMF_INVENTTABLEMODULELOG),false);
CodeAccessPermission::revertAssert();
As I stated, I have admin access to this, so should have the required security key. Though this is displaying the (usr) environment in the class list.
Are you sure it is running server side?
You did not expose your method definition.
I stumbled upon this issue in Ax 2009, while trying to set up a batch that reindexes tables from parameters.
The method doesn't need to be static or have server predicate. The only thing that works is setting the class "RunOn" parameter as "Server".
I know it's and old question with low views, but perhaps some poor soul can be saved.

First, thanks Hasura for incredible good product! I love it.
I have issue with derive action with Hasura Console. My use case:
I enable anonymous role for subscribe function (everybody can send email to subscribe)
I have configured permission on my subscribe table, everything is fine.
I want to validate the user input on server side, for example, validate email format. I have followed by this guide about derive action. I found no mistake here.
But I got the error "Type query_root must define one or more fields." when I hit "Derive action" at the first time.
According to this question, as I understand, I need to have object type for root query.
Of course, I will have object type for root query eventually. I can work around by giving some dummy queries for anonymous role. But I do not like that cheat anyway.
Any idea on that? Any help will be highly appreciated.

My related current version:
Hasura 1.3.2
One click deployment using Docker on Digital Ocean.
I have a StoredProcedure that returns a simple table containing several records:
DECLARE #STEPS_TABLE AS TABLE (OrchestrationID uniqueidentifier, [Message] nvarchar(1000));
-- LOADING THE VALUES HERE
SELECT * FROM #STEPS_TABLE As Step FOR XML AUTO, XMLDATA, ELEMENTS
I used the SQL Transport Schema Generation Wizard to create my schema and could configure the port correctly. If I use this schema on my orchestration, it works perfectly. BizTalk starts one instance of the orchestration everytime the #STEPS_TABLE has more than 1 record.
Reading Microsoft technical documentation, they recommend to get several messages in one call and then use the XML pipeline to disassemble the multi-row BizTalk message into a single-row BizTalk message.
I haven't used the XML pipeline before, so I tried the provided steps but couldn't get it to work.
Could somebody provide me a link to a "how to" (didn't find anything until now, after several hours of searching) or give me some hints to succeed.
Thanks in advance.
... some hours later I could figure it out myself. So if anybody comes across the same issue as me, here you have some guidelines to make it work on your environment.
At the end I followed a different walkthrough from Microsoft and avoided the pipeline recommendation altogether. The documentation I found is called "Disassembling Result Sets Using the SQL Adapter" and does exactly what i was looking for. You can just follow the whole walkthrough from Microsoft but avoid the creation of the send port and make some little adjustment on the receive port.
After following the technical document you will end up with two schemas, I will call them message and envelope (contains several messages) for the sake of this excercise. In your orchestration you can create a receiving port that maps to the message and then when you configure it as a SQL Port and you link it to your stored procedure (or select statement), you only have to change the Document Root Element Name to the envelope root name; the XML Receive pipeline (provided by default in BizTalk 2006) will do the magic of disassembling the messages contained in the envelope and instantiating an orchestration for each message.
The Microsoft "Disassembling Result Sets Using the SQL Adapter" walkthrough can be found under:

Mission accomplished :)
I have an SQL Database and an ASP.NET website built to put data into the database.
One of the project requirements is to build a system that would let the user upload a Crystal Report to the server and run it as needed. This way, the user could create a customized report (for then turning into management, customers) that wouldn't force them to go through a developer.
I'm looking for suggestions on how to accomplish this goal.
Currently, I'm looking for a way to redirect the database connection in the Crystal Report from the database it was developed with to the database it will eventually run on. However, There doesn't seem to be a simple way to do this.
I'm also investigating the ReportViewer object. However, all the code I have seen involves specifying the query for the report in the code, which isn't acceptable.
One option (which I don't like at all) is to let them write their own queries so they can copy the results into Excel. This would mean a blank textbox and information about the structure of the database. Not a good idea for multiple reasons.
Another option is to create one report for each table (and maybe a few extras), let the user copy the data they want into Excel, and go on their merry way.
tl;dr How do I build a flexible reporting system?
=========================================
Continuation: 08/20/2012
I have decided to go the route of b.pell's extension methods. So far, it has gotten me closer than anything else. My code to bind to the CrystalReportViewer is below:
CrystalReportSource rs = new CrystalReportSource();
rs.Report.FileName = Server.MapPath("ReportFiles/") + Request["reportname"];
string connstring = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString;
rs.ReportDocument.ApplyCredentialsFromConnectionString(connstring);
rs.ReportDocument.ApplyNewDatabaseName("myDBName", "mySchemaName");
rs.ReportDocument.Refresh();
CrystalReportViewer1.ReportSource = rs;
This comes very close to working. It works fine on my dev machine, but when I run the code on the server, it gives the following error:
Logon failed.Error in File CrystalReport2 {5D2E82E5-783E-4DFD-A770-C8AE72A51E4E}.rpt:
Unable to connect: incorrect log on parameters. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Runtime.InteropServices.COMException: Logon failed.Error in File CrystalReport2 {5D2E82E5-783E-4DFD-A770-C8AE72A51E4E}.rpt: Unable to connect: incorrect log on parameters. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
The error is in this line in the code:
crTable.Location = String.Format("{0}{1}", prefix, crTable.Location.Substring(crTable.Location.LastIndexOf(".") + 1))
When I remove the call to ApplyNewDatabaseName, I am asked to enter the Server Name, the Database name, the Username and the Password or to select Integrated Security. I can't enter the Database Name or the Server Name (those fields are disabled).
Any thoughts?
I think what you're looking for is the Reporting Services, part of Business Intelligence
Or maybe you can setup a UI that let the users pick the tables and columns they need for the report (this way you can limit the information they can access) an write a Dinamic Query Builder Function or something like that.
I answer the changing Crystal Reports connection question a lot (it's something I'd think Crystal would make easier, but I wonder if they don't because that's what their server product does). :D Anyway, you can set the database credentials at runtime. Crystal is very particular in the order it's done, but I have some code that I turned into extension methods that do the trick. This code will go through the main report and all sub reports and change the connection information. This assumes that all sub reports connect to the same database that the main report does (if not, you'll need to modify it to handle multiple connections, but this rarely comes up at least with what I do).
Extension methods to change connection info: http://www.blakepell.com/2012-05-22-crystal-reports-extension-methods
It would be used something like this (although, you're binding to a viewer probably and not exporting, so you could ignore that, this is just for example).
Using rd As New ReportDocument
rd.Load("C:\Temp\CrystalReports\InternalAccountReport.rpt")
rd.ApplyNewServer("serverName or DSN", "databaseUsername", "databasePassword")
rd.ApplyParameters("AccountNumber=038PQRX922;", True)
rd.ExportToDisk(ExportFormatType.PortableDocFormat, "c:\temp\test.pdf")
rd.Close()
End Using
System.Diagnostics.Process.Start("c:\temp\test.pdf")
You could use the Crystal Viewer at this point to deliver the reports and store the report in a database or on the file system (with a db meta data table) and have some predefined connections the user could select from that would be applied when it is run.
You also have the option to write your own front end. In this scenario a user would select a report from your meta data (you could put whatever security on it you wanted, I use AD). Then you can read the report parameters in and lay them out on the web form. When the user fills them in, you then sanatize them and pass them to the report via these extensions and you can output Excel, PDF, Word Doc, RTF, etc. A little more overhead and not the nice preview view, but can work well (I've done something like this in the past). Hope this helps.
About "...let them write their own queries" part of your question.
The solution can be to use some query builder component with friendly user interface which hides from users the complexity of your database and avoid any possible SQL injections.
There are few such products on the market. One of them is called EasyQuery, another one is build by Aspose if I'm not wrong. Try to search in Google for "query bulider for asp.net" or ".net query builder component".
I am getting the ORA-24778: cannot open connections, what are the possible causes?
We have a number of applications deployed in WAS7 profile and they connect to a number of schemas in Oracle 11g.
One of the schema is connecting through other schema via public DB link.
I cannot identify a solution for this cause.
After restarting the WAS7 profile, it is ok for a while and again start hitting the error.
Pls help!!
I assume you missed to tell us a few details:
You are using XA
You are using XA in combination with database links
You are using shared database links
The ora-24778 is not happening all the time
Either you haven't configured shared server option or you are not connected to a shared server. However Oracle requires you to user shared server if you want to use XA and database links.
Or the parameter OPEN_LINKS_PER_INSTANCE is not set sufficiently. Keep in mind mind that there is also a open_links init.ora parameter. The open_links parameter does not apply to XA.
This error can occur when you invoke a dblink in a existing transaction.
Database i am using is MySQL 5.1. I specified, i believe, right connectionstring in my web.config. but when i run my web app. it throws this exception:-
MySql.Data.MySqlClient.MySqlException: The user specified as a definer ('root'#'%') does not exist
Any help. Why am i getting this?
The source code for the stored procedures that you have been loading probably contain "DEFINER=root#'%'" as part of the definition - looking a bit like this:
create definer='root'#'%' procedure sp_test() begin end;
The problem here is that you do not have an account on your system for 'root'#'%'. This can be easily demonstrated. From the MySQL command line:
show grants for 'root'#'%';
I expect that this will come back with an error message:
ERROR 1141 (42000): There is no such grant defined for user 'root' on host '%'
The fix is to alter the source of your stored procedures, or to create the missing account:
grant all on *.* to 'root'#'%' identified by 'password' with grant option;
It is not generally a good idea to have such a high-powered account accessible from anywhere, but that is another story.
I know this answer comes very late, but I found a solution that doesn't involve changing any rights at all.
Go into your Stored Procedures and delete the DEFINER clause. The server should write in a new DEFINER that matches the user information you're logged in with.
Worked for me...
Is this in a stored procedure? Then maybe this blog post helps (emphasis mine).
All the settings were fine and I was wondering what’s causing the problem. At first rush I thought that it could be a cache, as I had requested recently to have xcache on our server.
But it wasn’t the case. The error was much more stupid than even one can imagine. That specific script uses a stored procedure to insert / fetch data to/from MySQL. The user who had created the sp was the one who was deleted. And that was the problem. The term “Definer” in terms of MySQL is the one who creates the stored procedure and for the stored procedure to be executed that user must exists.
