I'm Sure This Is An Easy One...Error Trap To Skip Over A Bad Object.
Mar 30, 2006
Hello, I have the following code to iterate through each view in a SQL
Server and call the "sp_refreshview" command against it. It works
great until it finds a view that is damaged, or otherwise cannot be
refreshed. Then the whole routine stops working.
Can someone please help me re-write this code so that any views that
fail the "sp_refreshview" command get skipped. I'm sure it's just a
matter of putting some basic error trapping into the loop, but I've had
a few goes at it and failed.
Many thanks.
DECLARE @DatabaseObject varchar(255)
DECLARE ObjectCursor CURSOR
FOR SELECT table_name FROM information_schema.tables WHERE table_type =
'view'
OPEN ObjectCursor
FETCH NEXT FROM ObjectCursor INTO @DatabaseObject
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC sp_refreshview @DatabaseObject
Print @DatabaseObject + ' was successfully refreshed.'
FETCH NEXT FROM ObjectCursor INTO @DatabaseObject
END
CLOSE ObjectCursor
DEALLOCATE ObjectCursor
GO

Hi,
I have a page with only a Datasource and a Gridview that allows Delete. In the database there is a referential integrity (RI) to the one of the columns. When a user tries to delete the row, the RI stops the delete and throws an error message the way it should. But it also create a hard failure on the page.
How do I trap the error message so I can display a message "Referential Integrity denied deletion of this record." rather than having it fail ?

I have a system using asp pages & ADO & SQL Server 2000, which processes files, builds a SQL insert statement from the file content and then executes it.
If the insert SQL fails, I need to know whether there was something wrong with the insert SQL, or something wrong with the database (e.g. SQL Server times out), and handle those differently,
Questions
=======
1. Is there an easy way to do this without checking against a list of error codes?
2. Can anyone point me to a list of errorcodes? Can't find this anywhere
thank you

Hi All,
I have a database with primary and Unique key contraints on SQL Server 2000. I'm front ending it with Access 2k.
I want to trap the error when the Unique key constraint is hit, but i can't capture the error number. All attempts return error 0.
The error i get is
[Microsoft][ODBC SQL Server Driver][SQL Server]Violation of UNIQUE KEY constraint 'IX_lut_Referral_Source'. Cannot insert duplicate key in object 'lut_Referral_Source'. (#2627)[Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated. (#3621)
I've tried the soultion given here http://support.microsoft.com/kb/q185384 but now get a Type mismatch error on errStored
SaveRecODBCErr:
' The function failed because of an ODBC error.
' Below are a list of some of the known error numbers.
' If you are not receiving an error in this list,
' add that error to the Select Case statement.

Greeting All, I have a stored proc that dynamically truncates all thetables in my databases. I use a cursor and some dynamic sql for this:......create cursorLoop through sysobjects and get all table names in my database.....exec ('truncate table ' + @TableName)Now, I want to be able to determine if an error occurred or not nad logthat error to a table in another database.However, when I try to trap the value of @@ERROR after theexec ('truncate table ' + @TableName) when an actual error occurs itfails. My error was synthetically created by placing a foreign key onthe table which precludes the option of truncation:Server: Msg 4712, Level 16, State 1, Line 1Cannot truncate table 'MyTable' because it is being referenced by aFOREIGN KEY constraint.The actual relevant code snippet is:BEGINBEGINSET @v_RowCount = (SELECT rowcntFROM sysindexesWHERE id = (SELECT idFROM sysobjectsWHERE name = @v_Name)AND indid IN (0,1))EXEC('truncate table ' + @v_Name)-- If there was an error truncating the current table.-- Write the event to the MessageLog table.IF (@@ERROR <> 0)BEGINSET @v_OutputMessage = ('There was an error ' + @v_name)INSERT INTO MessageLog (message) values (@v_outputmessage)RETURN (-1)ENDLike I was saying, when the error is generated because of the foreignkey the variable @@error is never set to 4712, in fact if I were to puta "select @@ERRROR" directly below the "exec('tru..')" statement itwould never be executed. The only thing that would show up inEnterprise Manager would be the:Server: Msg 4712, Level 16, State 1, Line 1Cannot truncate table 'MyTable' because it is being referenced by aFOREIGN KEY constraint.Any ideas as to what is going on here?Thanks, TFD.

Hi,
On my aspx Web page, I want to delete a member from database table 'tblMember', but if this MemberID is used as FK in another table, I want to display a user friendlier message like "You cannot delete this member, ....." I am using Try, Catch blocks in my Web Page.
Currently it display this message:
"DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_..._....' The conflict occurred in database '...', table 'tblMembers', column 'MemberID'. The statement has been terminated. "
So how should I precisely trap this error? Does anybody know what Exception is it? or what error number in SQL server?
Thanks

Hello
I am tryung to execute a Store Proc using Execute SQL Task.
I am very aware that if there is any errors occur I have handled it sufficiently.
All I want to do is, when ever there are any errors in teh Store Proc then this Execute SQL task should not fail and it should go for the next Task in teh control flow.
How can I do this?

Does sql server have a way to handle errors in a sproc which would allowone to insert rows, ignoring rows which would create a duplicate keyviolation? I know if one loops one can handle the error on a row by rowbasis. But is there a way to skip the loop and do it as a bulk insert?It's easy to do in Access, but I'm curious to know if SQL Server propercan handle like this. I am guessing that a looping operation would beslower to execute?

Hello All
Not sure if this is the right forum to post this question to, so if it's not, please accept my apologies.
I'm working in SQL Server 2005 with a database that was migrated to 2005 from SQL Server 2000. I have to alter a trigger on a table for some functionality changes, and when I modify the trigger and then access it through the application the database is working with, I receive this error:
There was a error in the [stored procedure name] procedure. Error Number: -2147217900 Error Description: [Microsoft][ODBC SQL Server Driver][SQL Server]The definition of object '[trigger name]' has changed since it was compiled.
[stored procedure name] and [trigger name] are where the actual names appear in the message.
I've tried running sp_recompile on the trigger, stored procedure, and table that are associated with this, and nothing works. I have dropped the trigger, which allows the save process to complete (but doesn't perform the required functionality, of course), and then re-created the trigger, but the error message still comes up. The compatibility level for the database is SQL Server 2000 (80) (as it was migrated from SQL Server 2000 as I mentioned above).
Has anyone seen this, and if so, how can I fix it?
Thanks in advance for your help!

Help! I have posted this before and I had hoped that the VS2005 SP1 would help my problem. It didn't. My code is shown below. I have dropped a sqlconnection, sqldataadapter and a strongly-typed dataset from the toolbox onto the component designer for my page and written my code. It compiles without any errors but at runtine I receive the system error "Object reference not set to an instance of an object." The error occurs at the first line where the sqldataadapter is mentioned. I have shufflled the code and the error still occurs at first mention of the dataadapter. I have set parameters to a simple string such as "myemail." It hasn't helped. I have used the "Dim" statement as "Dim DaAuthorLogin as System.Data.SqlClient.SqlDataadapter and Dim DaAuthorLogin as New ......) at the start of the private sub generated by the event requiring the data. Nothing helps. Here is my simple code to select data from a sqlserver 2000 database. Why do I continue to get this error?

Hi,
I am trying to develop a custom algorithm. I have implemented and tested training methods, however I fail at prediction phase. When I try to run a prediction query against a model created with my algorithm I get:
Executing the query ...
Obtained object of type: Microsoft.AnalysisServices.AdomdClient.AdomdDataReader
COM error: COM error: DMPluginWrapper; Object reference not set to an instance of an object..
Execution complete
I know this is not very descriptive, but I have seen that algorith doesn't even executes my Predict(..) function (I can test this by logging to a text file)
So the problem is this, when I run prediction query DMPluginWrapper gives exception -I think- even before calling my custom method.
As I said it is not a very descriptive message but I hope I have hit a general issue.
Thanks...

Just installed VS 2005 & SQLServer 2005 clients on my workstation. When trying to create a new Integration Services Project and start work in the designer receive the MICROSOFT VISUAL STUDIO 'Object reference not set to an instance of an object.' dialog box with message "Creating project 'Integration Services project1'...project creation failed."
Previously I had SQLServer 2000 client with the little VS tool that came with it installed. Uninstalled these prior to installing the 2005 tools (VS and SQLServer).
I'm not finding any information on corrective action for this error.
Any one have this problem and found the solution?
Thanks,

Hello -
For the life of me I cannot figure out why i'm getting the "Object Refence Not Set To an Instance of An Object" error after I try and create a Report Services project in Business Intelligence Studio. I've followed all of the steps in similar posts such as checking the ReportServer/web.config file but everything checks out.
Does anyone have any other ideas as to how I can get rid of this annoying error and start creating some reports?
Thanks!!!

There are certain errors that does not come during compilation and it shows during execution because of late-binding concept implemented in SQL Server from 7.0 version.
The problem is when Tables are not there, SPs are created. And there is no option where we can set like 'Validate object resolution during compilation"
There are lot of SPs that are in invalid status because the tables are really not there and SP needs to be modified to reflect the correct table name. In Oracle, if I have to find the list of objects that are in invalid state (because of object resolution problems), it was possible. How do I do it in SQL?
I need a listing of all objects in my database that is in invalid state. Searched in NET but there seems to be no supporting tool also that lists invalid objects.
Pl let me know whether there exists a way by which I can get to know the invalid object lists in my SQL 2005 database

Hi,
I'm struck with a small issue.. would be great if somebody can help me out. Here is te scenario
1. There would be more than one CSV files in INPUT folder.
2. I'm using a Foreach Loop file enumerator to loop thru the files and load the data into database.
3. If loading is successful the file need to be moved to ARCHIVE folder and next file needs to be picked up for loading
4. In case if there is an error in loading the file has to be moved into ERROR folder, Error description should be logged to error log text file and next file needs to be picked up for loading.
I don't think increasing max error count is an option as I don't know how many no. of input files are available as it depends upon the feed.
What is the best way to go.

I am trying to move data from Access to SQL Server 2000 using DTS.
I have an Access Source and SQL Server Desitination, My destination table has a field called tableID that is not in the source. TableID is a Primary Key and an Identity column.
I have Enable Identity Insert checked in the options of the Transform Data Task.
When I execute ythe task, I get the error
"Cannot insert the value NULL into column 'TableID'. Does not allow nulls. Insert Fails.
Does anyone know why this simple task would fail?

Hi
I am trying to create a trap to catch one of my developers which is messing around on my Live system, where he doesn't belong. I have already created a trigger which is logging and catching the guy out, but i need to know which queries he is executing on this table.
Here is my trigger:
Code Block
ALTER TRIGGER [dbo].[ctr_SQLTrapDelete] ON [dbo].[Members]
AFTER DELETE
AS
INSERT INTO SQLTrap ([User], TYPE, DateValue, HostName, SystemUser, TableName)
SELECT USER_NAME(), 'DELETE', GETDATE(), HOST_NAME(), SYSTEM_USER, 'Members'
I want to add a Query field at the end of the table with the query that the guy executed.
Will anyone be able to tell me how where i am going to find the query that he executed, i am unsure of where it will reside.
I think possible in the Master.dbo.syscomments table but i'm unsure of how i am going to track the query to insert it into the table with the timestamp.
Any help will be greatly appreciated.
Kind Regards

We are running SQL 2000 sp3a on Win2003 Server with all patches and SPs applied.
I want to run a stored procedure from a SQL Agent job. I want the stored procedure to run as a TRANSACTION to force a ROLLBACK in case of failure. However, if execute the procedure and an error of severity level 20 (I think) or greater happens I get blown out of the job immediately. Therefore I cannot call RAISEERROR or use @@ERROR. So, how do I assure that I can ROLLBACK the TRANSACTION?
I have searched the web and BOL and cannot find anything that addresses this specifically.
Thanks in advance for any help.

I'm using System.Net.Mail in a script task to send HTML email via SMPT client as follows:
Imports System
Imports Microsoft.SqlServer.Dts.Runtime
Imports System.Net.Mail
Imports System.Net
Public Class ScriptMain
Public Sub Main()
Dim myHtmlMessage As MailMessage
Dim mySmtpClient As SmtpClient
myHtmlMessage = New MailMessage("<from>", _
"<to>, _
"Test HTML Message", _
Dts.Variables("HtmlText").Value.ToString)
myHtmlMessage.IsBodyHtml = True
mySmtpClient = New SmtpClient("<smtpservername")
mySmtpClient.Credentials = CredentialCache.DefaultNetworkCredentials
mySmtpClient.Send(myHtmlMessage)
Dts.TaskResult = Dts.Results.Success
End Sub
End Class
I need to be able to trap an error when the email address is undeliverable. Is there a way to do this in SSIS? I am validating the email address before sending, but it can still come back as undeliverable. I need to be able to catch this.

In trying to upgrade my sql express install from express to developer edition, I ended up having to delete all things express from my computer and do a clean install of developer edition (as i installed developer edition initially over sql express but this didnt seem to work; express edition still appeared in add remove programs etc). Anyway so i blew away the install and have a clean install of developer edition. Now when I create a new website in Visual Studio 2005 and try to add a database to the project, it gives me an error stating that i need to have sql server express 2005 installed to function properly... Do i need to have express AND developer edition of sql installed to do this? I would think developer edition of sql would enable me this functionality...http://img277.imageshack.us/img277/4228/sqlerrorie2.jpgThanks!It is also worth noting that I get the dreaded remote connection error when trying to connect to a db that I used to be able to connect to when I was using sql express (the aspnetdb database that is created when you user their membership stuff)"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) "However, I did the following successfully:1. create a database using the sql management studio2. added a table and some data to it3. threw a dataset into the website4. added a gridview to a page in the website, pulling data from the dataset5. and the website runs successfully populating the page with data...fyi: My sql services: http://img158.imageshack.us/img158/2020/sqlserviceshj6.jpg

My simple question:
Is there any way to prevent unimportant errors in a stored procedure from causing exceptions in my C# code? This is preventing the SqlAdapter from filling the query results into my DataSet.
The Setup:
I have a Stored Procedure in Sql Server 2000 which has a text parameter called @Xml. I send in an Xml document to process. This document contains several "records" to process. The format of the xml really isn't important.
I create a temporary table called #Results to hold the results of processing each record in the xml.
To process the xml I have a Cursor which loops over a SELECT from the xml.
For each record, the sproc attempts to make a series of INSERTs and UPDATEs inside of a transaction. Any one of these commands may fail because of constraint violations or attempts to insert NULL into non-null columns, or such. After each command I check @@ERROR. If it is not zero, I stop processing the record and rollback the transaction. The cursor loops around and tries the next record. Each time the success or failure of the transaction is recorded into the #Results table.
When the cursor is done looping I 'SELECT * FROM #Results'.
I've tested this many times in the Query Analyzer and each time, regardless of any errors, I can see the result set from the SELECT of the #Results table in the Grids tab. The Messages tab shows each of the errors that occurred.
I try to call this stored procedure using the following code:
int c = 0;
try
{
sqlAdapter.Fill( sqlDS );
}
catch( System.Data.SqlClient.SqlException )
{
c = sqlDS.Tables.Count;
}
The value of c will always be zero, if there were any errors during the execution of the stored procedure. The DataSet does not get filled, even though the stored procedure is returning a result set. This is a problem for me because I expect errors to occur, and I need to know which records from the Xml caused those errors.
Is there any way to clear the errors in my stored procedure so that they don't turn into exceptions in my code? Or, is there anyway to get the Adapter to fill the DataSet regardless of any errors that were encountered?
I've also tried this with a SqlDataReader. The reader never gets assigned to because SqlCommand.ExecuteReader() throws an exception.

Dear all,
I am running into a null reference exception on replication with SQL Server 2005 Compact Edition. The problem occurs at repl.synchronize(). Even though the statement is inside a try-catch block, the exception is not caught, and the application quits.
Device O/S: Windows Mobile 5.0 v 5.1.195 Build 14957.2.3.1
Hardware: Dell Axim X51v, Intel PXA270
Database: SQL 2005 SP2 (no post SP2-patches)
Exception shows as "an unexpected error has occured in AppName.exe. Select Quit and then restart this program, or select Details for more information." Details:
.. at NullReferenceException at AppName.Form1.Synch()
.. at .... (various lines)
.. at AppName.Form1.Main()
The application is based on the tutorial (Creating a Mobile Application with SQL Server Compact Edition) at http://msdn2.microsoft.com/en-us/library/ms171908.aspx.
The application was successfully working initially but then stopped working on replication after some minor modifications which were not related to the replication code, e.g. adding some buttons to the form.
Three things are puzzling me here..
1. The fact that this is a NullReferenceException and not a SqlCeException
2. Why the try-catch block doesn't work
3. Why the exception occurs
Is this a bug or am I doing something wrong here?
Any help would be appreciated.
Code sample below:
Sub Synch()
Try
LogMsg("Deleting db...")
DeleteDB()
LogMsg("Initializing repl...")
Dim repl As New SqlCeReplication
repl.InternetUrl = http://192.168.0.100/SQLMobile/sqlcesa30.dll
repl.Publisher = "TRKSRV"
repl.PublisherDatabase = "trk_db"
repl.PublisherSecurityMode = SecurityType.NTAuthentication
repl.Publication = "Trk"
repl.Subscriber = "Trk"
repl.SubscriberConnectionString = "Data Source=""Program FilesTrk2007DefectTrk.sdf"";Max Database Size=128;Default Lock Escalation =100;"
LogMsg("Adding subscription...")
repl.AddSubscription(AddOption.CreateDatabase)
LogMsg("Synch...")
repl.Synchronize()
LogMsg("Cleanup...")
repl = Nothing
Catch err As SqlCeException
MessageBox.Show(err.ToString & " " & err.HResult & " " & err.NativeError & " " & err.Message & " " & err.InnerException.ToString)
Catch err2 As Exception
MessageBox.Show(err2.ToString & " " & err2.Message.ToString & " " & err2.InnerException.ToString)
End Try
End Sub

Hi all,
Suppose I have set a CHECK constraint to a column where Salary field is not permitted to be less than 1000 or greater than 10000.
In this situation, when I insert a new record with salary as 10, using a stored procedure from Visual Studio, how will I trap the error from C# Code?
Thanks
Tomy
