Hi,I am using sql server 2005 and i am having table with a column which has unique key constraint.So if the user tries to enter the duplicate value for that particular column and try to save it ,it errors out in runtime..how do i raise the user friendly error message in this DB error, when user tries to save it.Thanks
View 9 RepliesHi all,
I was wondering whether there is a way to show the user an error when the user did not select a specific parameter.
In my case, I have two optional parameters. The user has to select either one to view the report. If the user does not select either one, I would like to show some sort of an error page indicating so. However, all i am getting is a complete blank with no report in sight. I as a developer know this is an error as a result of missing parameters, but i was wondering whether I could produce a page or direct it to a page so that the user doesn't go all horrified at an empty page ?
Thanks

The notorious situation: a duplicate key exception. Users register themselves using fancy nicknames.This often leads to conflicts. In addition, as I point out in error reporting -- to except or not expect or return, the conflicts can not be prevented in a distributed environment (one ensures that there in no such name and still can get a concurrent conflict). For these reasons, the apps should be prepared to the conflicts. The cases to which apps are prepared, are not exceptional.
Meantime, if the engine insert process fails things naturally, we get an exception with a message like "Violation of UNIQUE KEY constraint 'col_name'. Cannot insert duplicate key in object 'table_name'. At first, it is not quite informative. Customers prefer to see something like: "a user with such a name already exists". Additionally, as explained in the referred topic, exception processing is extremely CPU consuming and should be not normally used as a function "feedback" tool.
The option to prevent the exception raising by preceding the INSERT op by a table-locking SELECT is not attractive either because of 1) locking and 2) double checking. Obviously, we get the conflict exception on INSERT because the DB engine precedes the insertion by a select. How it would check the existence of the same key in the table otherwise? I want to say that the only thing we should do is to override the default DB error handler.
How do I know that the error was caused by some specified constraint violation letting other issues to fail naturally? Should I parse the exception message looking for key_name?
Is there a way to display a friendly message if a sub-report does not have content ex "No additional products available"...
View 2 Replies View RelatedI feel like I'm missing something obvious here, but I'm stumped...I have a stored procedure with code that looks like:INSERT INTO MyTableA ( ...fields... ) VALUES (...values...)IF (@@ERROR <> 0)BEGINROLLBACK TRANSACTION;RAISERROR('An error occurred in the stored proc.', 16, 1);RETURN(1);END--FORCING AN ERROR AT THE END FOR TESTING PURPOSESRAISERROR('Proc Successful',16,1)On MyTableA, there is a trigger that loops through the inserted data andstops the insert in certain circumstances, returning an error:IF (some criteria)BEGINROLLBACKRAISERROR('An error occurred in the trigger.',16,1)RETURNENDWhen I call the stored procedure from VB (connecting via RDO) witherror-causing data, the trigger successfully stops the insert, and adds thetrigger-error-msg to the errors collection, but it does NOT seem to createan error situation back in the stored procedure. The procedure finishes upwith the "Proc Successful" message, so that when I iterate through theerrors collection back in VB, I have "Proc Successful" followed by "An erroroccurred in the trigger."Is there some way I'm not finding to have the calling procedure recognizethat a raiserror occurred in the trigger and behave appropriately for anerror situation?Jen

Ok so I'm using the Management Studio Express and was able to log in and get into the database server, but I had to click the "options>>" button and change database I wanted to connect to from <<default>> to my database on the server or else I get the "cannot open user database, login failed" error message.Then I right click my database and it gives me the "Cannot open user database. Login failed" error message, even though I already connected to the database to login during the connect screen. Also I'm able to interact with the database using SQL QUERIES in the Management Studio, like adding new tables with it, but if I right click the database and click "add table" I get that error.What gives? I know I have permission since I was able to log on, and modify the database using SQL queries but if use the GUI I can't use it. I can't even right-click select "properties" without getting that error. The reason I want to use the GUI is because I want to right click and use the backup feature of the database.My guess is that Management Studio continues to point to the default database(which gives me that message) after I already logged in, so I have no idea how to change the default database that management studio points to, to the one I do have permission to use. Thanks in advance.

Hi,
I am building a custom component. In the Validate() method I am checking for various things. Here's a section of my code:
if (ComponentMetaData.InputCollection[0].InputColumnCollection.Count != 1)
{
return DTSValidationStatus.VS_ISBROKEN;
throw new Exception("You need to select one and only one column");
}
The problem I'm finding is that my Exception never gets thrown so I never see the error in the UI. if I reverse the 2 lines like so:
if (ComponentMetaData.InputCollection[0].InputColumnCollection.Count != 1)
{
throw new Exception("You need to select one and only one column");
return DTSValidationStatus.VS_ISBROKEN;
}
Then I get my error message in the UI but I never get anything returned from my Validate() method - which doesn't seem quite right to me.
I don't like using FireError() either because it merely puts the error into the Task list window - and who ever looks at the Task list window???
I'm basically just after some guidance about what people think is the "proper" way of doing this. At the moment I prefer to throw an exception because that way I get some errors in the UI.

When a catchable error occurs in a try block, control is passed to theassociated catch block. While I am then able to examine properties ofthe error using such functions as ERROR_NUMBER() in the catch block,the error-logging scheme used in my company requires that the actualerror be raised so that it can be picked up by components in the nexttier. I appear to be unable to do that -- I can raise some other errorthat has all of the properties of the original except the error number.For example, division by zero raises error 8134. If the code thatproduces that error is enclosed in a try block, I seem to be unable toraise that error from the catch block. Of course, if I never used thetry block to begin with this wouldn't be a problem, but then wewouldn't have the advantages of this structure as it applies to othererrors, some of which we may wish to handle differently. WhileTry-Catch looks great as a way of allowing us to handle errors in acustomized way and to avoid having all errors be passed up to ourmiddle tier, it seems that we are unable to pass ANY such errorsforward, and that is a problem for us, too. Is my understanding ofthis situation correct, or is there some way around this problem, e.g.,is there any way I could have raised error 8134, in the above example?Thanks.

I am having a problem getting informational type messages to display for my end users.
I have a SQL2000 db with a Delfi front end. When I issue either the raiserror or print nothing is displayed inside the app. With raiserror I can get it to display if I make the severity higher than 10. The problem with this is that it stops the app from processing the transaction. This is ok in one case but not with just informational type stuff. Any suggestions? Thanks.

I am new to SQL server and I am looking for the best practiceregarding the following:The GUI for the database I am creating has a number of questions like:A. Where are you currently living?1) In my own home2) In the home of a family member3) In a shelter4) On the streetHowever, for speed of data entry, the GUI (it's a web front-end,ASP/VBScript) accepts the number only. Futhermore the database onlystores the number entered.So for example for the above question, when the user is doing the dataentry, they would just enter a 1, 2, 3, or 4.However, when viewing the data, the end user wants to see the textthat corresponds to the number. So for example, if the user entered"3" for the above question, when they are viewing the data in the GUI(not to make edits, just viewing), they want to see "(3) In ashelter".My question is how best to display these friendly values?Should I do all the conversions in a stored procedure? If so, whatwould be the best way to do that? I tried something like this:SELECT Current_living =CASE Current_livingWHEN 1 THEN '(1) In my own home with my partner'WHEN 2 THEN '(2) In the home of a family member'ELSE NULLENDFROM tbl_DemographicInfo WHERE ClientID = @ClientIDbut I can't figure out how to do this for multiple fields.ALSO, I'm not sure if burying this stuff in a stored proc is the wayto go, because if the client wants a slight change to the friendlyname I have to get into the SP and change it. Seems like there mustbe a better way.I can also do this in the ASP code, but that also doesn't seem likethe best practice.I can have a lookup table, but again, where do I do the conversion?In an SP? With a view?Again, I'm looking for the best practice here. I know some ways Icould do it (like in the ASP), but I want to do it efficiently andcorrectly.Any help/comments are greatly appreciated.thanks in advance,Jon LaRosajlarosa at alumni dot brown dot edu

I'm trying to use an XML Task to do a simple XSLT operation, but it fails with this error message:
[XML Task] Error: An error occurred with the following error message: "There are multiple root elements. Line 5, position 2.".
The source XML file validates fine and I've successfully used it as the XML Source in a data flow task to load some SQL Server tables. It has very few line breaks, so the first 5 lines are pretty long: almost 4000 characters, including 34 start-tags, 19 end-tags, and 2 empty element tags. Here's the very beginning of it:
<?xml version="1.0" encoding="UTF-8"?>
<ESDU releaselevel="2006-02" createdate="26 May 2006"><package id="1" title="_standard" shorttitle="_standard" filename="pk_stan" supplementdate="01/05/2005" supplementlevel="1"><abstract><![CDATA[This package contains the standard ESDU Series.]]></abstract>
There is only 1 ESDU root element and only 1 package element.
Of course, the XSLT stylesheet is also an XML document in its own right. I specify it directly in the XML Task:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"/>
<xsl:template name="identity" match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="kw">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:attribute name="ihs_cats_seq" select="position()"/>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Its 5th line is the first xsl:template element.
What is going on here? I do not see multiple root elements in either the XML document or the XSLT stylesheet.
Thanks!
I have a stored procedure that returns a set of tables based on data in a table for a company. These tables are being used to create drop down lists for criteria selection for the client. We have a Javascript based control that will make use of these based on the control name. So... ideally, I would like the stored procedure to return tables named "EmployeeID", "ResourceName", so that I can accurately name the controls when they are being created. The data that is returned is not static, so, for example, client 1 may see the EmployeeID drop down, while client 2 may not.
I searched and didnt see anyone that was able to accomplish this in this way, but wanted to post something here before I moved forward in a different direction.
I am thinking that I will likely return an extra table with the field names and their corresponding tables (i.e. "EmployeeID"/"Table0", "ResourceName"/"Table1", etc...)
Thanks,

Hi experts,
What I am trying to do is to open an existing report in a Print Friendly format .
What is the simplest way to do this using Visual Studio?
Here's the sort of thing I hope is feasible:
I can open my Report on a web page , then on that page can be a button / link for the user in case they want to open
that report in a separate window.
So I'd like to jump to that page by jumping to an URL and sending all parameters
something like :
http://Dev_Server/Reports/Pages/Report.aspx?ItemPath=%2fMy+Reports%2fTest+Report&rsaramOne=Parameters!paramOne.value + paramTwo=Parameters!paramTwo.value + etc all other parameters , I have on that report
Any suggestions would be really appreciated .

Hi, all experts here,
Thank you very much for your kind attention.
I am trying to create a new mining structure with case table and nested table, the case table (fact table) has alread defined the relationships with the nested table(dimension table), and I can see their relationship from the data source view. But why the wizard for creating the new mining structure showed that message? Why is that? And what could I try to fix it?
Hope it is clear for your help.
Thanks a lot for your kind advices and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,
I just started playing with sqlagent and am finding that viewing a specific message from an ssis step is cumbersome when other entries are also in the log. Exporting seems only able to export all history entries. Viewing right in the log viewer leads to a series of boundary expansions and right scrolls that dont seem convenient for quick identification of a problem in a medium sized ssis message. Right clicking on the message in the viewer seems like it is preparing the message for possible copy but it seems to end there. I'm already familiar with the different levels of verbosity available in the command line. Dont see anything useful on the web.
Is there a user friendly way to copy the contents of a specific message for perhaps pasting to notepad , so that problem identification is facilitated? Is there a not so user friendly way available, one taht doest involve 1st exporting the entire log?

I'm wondering, why CLR user-defined-types are case-sensitive in T-SQL?
When I create an udt with vb.net, e.g. udtPoint with properties X and Y and a method ToString(), I have to write udtPoint.X ..., udtPoint.x would raise an error. udtPoint.tostring() isn't working, too.
I like vb, because you don't have to remember whether syntax is upper or lower case. Same is with T-SQL, there's no difference between select * from table and Select * FROM Table. Intellisense would by great, but is not yet implemented .
I'd like to put this topic under suggestions (in my opinon it's a bug), what do you think about it?
Many thanks for your answers!
Hi Im getting the following error when trying to connect to a php page...any ideas
message: Login failed for user 'NT AUTHORITYNETWORK SERVICE'. (severity 14)
I notice when I copy an SSIS package 'A' to a new package 'B', the new package 'B' will generate a "login failed for user" message in the data flow components. To copy I "save copy of Package 'A' as."
Some config info:
Package ProtectionLevel = EncryptSensitiveWithPassword
Connections are Data Sources
Connection strings with password are stored using PackageConfigurations to an SQLServer table. I've verified Package 'A' is in fact using the config table (e.g. it is not using a password or user stored in the package)
Data connectios are all SQLServer Native OLE DB Client
The account is an SQLServer account (not integrated security)
The original Package 'A' works flawlessly and I get success when I test the connections in Package 'B'.
But executing package 'B' I get: The error message I get is: [Connection manager "MyConnection"] Error: An OLE DB error has occurred. Error code: 0x80040E4D. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Login failed for user 'dwuser'.".
Does anyone know why this would occur and/or how to work around it? I saw another thread where a potential workaround is to create a new data flow task and copy all the data flow components to that task. That won't work well for us because the data flow is moderately complex and when you copy and paste it, SSIS completely re-orders the layout.
This is a typical data warehouse ETL setup where there is a master package that executes child packages (e.g. 'A', and 'B' mentioned above) that each perform the ETL for a specific dimension or fact table.
Thanks for any help,
