Can I Roll Back Certain Query(insert/update) Execution In One Page If Query (insert/update) In Other Page Execution Fails In Asp.net
Mar 1, 2007
Can I roll back certain query(insert/update) execution in one page if query (insert/update) in other page execution fails in asp.net.( I am using sqlserver 2000 as back end)
scenario
In a webpage1, I have insert query into master table and Page2 I have insert query to store data in sub table.
I need to rollback the insert command execution for sub table ,if insert command to master table in web page1 is failed. (Query in webpage2 executes first, then only the query in webpage1) Can I use System. Transaction to solve this? Thanks in advance

Hello All,
I have a Conditional Split, where there are two outputs.
First output is a dataset which is to be inserted into the database.
Second output is a dataset for which the data already exists in the DB. I just need to update those data.
I have a doubt here. I want the insertion to be done first and then updation.
Is there any property to be set for insertion or updation, something that maintains the order of execution or priority of execution.
Please do ask me if you need any further clarification.
Thanks,
Kapadia Shalin P.

A problem has come up in designing a Web page to maintain a small reference table in SQL Server 2000 (9 columns, about 25 records).
I tried to design the Web page to allow INSERT and UPDATE operations using a single page that posts back to itself. The page contains a set of empty form fields for a new record, followed by a set of filled-in form field for each row in the table. The form fields for existing records are given a unique name based on the field name concatenated with the primary key value for that row.
If I set up the page to INSERT only, it works properly. But when I add the fields for existing records, the INSERT operation malfunctions. Specifically, anytime a set of existing fields for a particular column is added to the page, the INSERT will no longer work properly for that column. This is true for all fields except the primary key field. It always INSERTs correctly. I tried adding only some columns to the set of existing form fields. In that case, the INSERT operation added the correct values for the fields that were not listed in the existing records section, but failed for the others.
I am using the INSERT INTO syntax for that operation and the recordset .Update syntax for the edits. I tried using the recordset .AddNew/.Update syntax for the insert, but it exhibited the same problems. The column data types contain smallint, bit, nvarchar, and ntext types.
I know that the correct values are being put into the INSERT statement. I also tried renaming the INSERT form fields to be totally different than the names of the existing record fields. But the problem comes back no matter what.
If necessary, I can split the logic so that inserts and updates are handled by different pages. But I would like to make this work if possible. If a reader knows why SQL Server is causing this problem, any help would be greatly appreciated.

Hi,
I'm reasonably new to ASP.NET 2.0
I'm in my wizard_FinishButtonClick event, and from here, I want to take data from the form and some session variables and put it into my database via a stored procedure. I also want the stored procedure to return an output value. I do not need to perform a select or a delete.
For the life of me, I can't find a single example online or in my reference books that tells me how to accomplish this task using a SqlDataSource control. I can find lots of examples on sqldatasources that have a select statements (I don't need one) and use insert and update sql statements instead of stored procedures (I use stored procedures).
I desperately need the syntax to:
a) create the SqlDataSource with the appropriate syntax for calling a stored procedure to update and/or insert (again, this design side of VS2005 won't let me configure this datasource without including a select statement...which I don't need).
b) syntax on how to create the parameters that will be sent to the stored procedure for this sqldatasource (including output parameters).
c) syntax on how to set the values for these parameters (again...coming from form controls and session variables)
d) syntax on how to execute, in the code-behind, the stored procedure via the sqldatasource.
If anybody has sample code or a link or two, I would be most appreciative.
Thank you in advance for any help!

Hi All,
Please look at the following tables. I have Two tables
Data and TmpData with the following structure.
Data ( All int columns, ID column is Primary and identity)
Id UserID PrgID RoldID
322112
323122
324132
325212
326222
327232
328312
329322
330332
TmpData
Id UserID PrgID RoldID
82113
83123
84133
85213
86223
87233
912012
922022
932032
942112
952122
962132
Now I need to run a query so that
Part 1: It updates existing RoleId columns ( Based on Userid,PrgID) in 'Data' Table with corresponding values from 'Data' table.
Part2 : It inserts new rows in 'TmpData' to 'Data' table.
I am done with Part1 using the simple update statement.
Update Data
Set Data.programroleid=tmp.ProgramRoleID
from TmpData tmp
where Data.userid=tmp.UserId
and Data.programId=tmp.ProgramId
This works fine for existing userids,programids in 'Data' and 'TmpData' tables. But I am struggling with inserting new rows into Data from 'TmpData' ( That exists only in 'tmpData' table). Based on above table structures how do I insert new data into 'Data' table from 'TmpData'.

Hi, I have the following query:UPDATE lista SET audio='3847f5e9-4ef7-42d7-9e57-e5cbad9131b1.jpg' WHERE id='13';If the id already exists it'll modify the row correctly as expected. But if the id doesn't exist at the table I want the row to be inserted anyway, but this is not happening. The same query works well in mysql + php. The table has an identity increment of 1 for the primary key also. Any ideas?Thanks in advance.

I'm trying to update (increment)
Company.SumtotalLogons
from CompanyUsers.NumberOfLogons
where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
any ideas?

Here is my problem. There is a form where some information has to be filled out while the other does not. Information that is left blank is not inserted into the database so that I don't have millions of empty rows. This works perfectly, keeps the database accurate. When someone goes to update, if they add something new it would need to be inserted, since there is nothing to update. I was going to write a procedure, but that seems like such a waste since this will happen often. Is there an sql command in MS SQL to do this. I tried all of the sql commands from other databases I had used. (I am new to MS SQL). If there isn't one does someone have a procedure that won't create a huge amount of overhead.

Hello,
I seem to have a strange problem in that my code runs fine, but I am trying to INSERT rows into a database, and the rows affected by the INSERT command is alwsy zero, even though no error is thrown. Hence no data gets inserted.
Here is the code:
void recordTick(string pair, DateTime time, decimal sell, decimal buy)
{
SqlConnection thisConnection = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FOREX.mdf;Integrated Security=True;User Instance=True");
insert = "INSERT INTO " + pair + " VALUES(" +
"'" + time.ToString("yyyy-MM-dd HH:mms") + "'," +
"'" + sell.ToString() + "'," +
"'" + buy.ToString() + "'" + ")";
thisConnection.Open();
SqlCommand command = new SqlCommand(insert, thisConnection);
Int32 success = command.ExecuteNonQuery(); // success always = 0!
thisConnection.Close();
}
The database is type .MDF that I created with the Project/Add Component/SQL Database menu. I can inspect it easily in Server Exporer and add data manually with no problem.
Can any one suggest how to get the INSERT to actually add the data?
Any help much appreciated!

I have an SSIS Package which Retreives Data using a SQL Query like below
select a.* from dbo.test a (nolock)
JOIN dbo.test1 b (nolock)
ON a.DetailsId = b.DetailsId
JOIN dbo.test c (nolock) on c.DetailsLineId = b.DetailsLineId
where convert(date,c.CpPlacedDate)>?
and convert(date,c.CpPlacedDate) < convert(date,GETDATE())
and c.PartnerCode in ('akakak07')
The CpPlacedDate DataType is Datetime. After the Successfull Execution of SSIS Package the final output results in destination is lesser than source.
The Maximum of cpplaceddate in the Destination for a particular date is '2015-06-13 23:46:08.923'
The Maximum of cpplaceddate in the Source for a particular date is '2015-06-13 23:59:14.873'
I am missing 16 records in between this time Gap.

Hello, I'm new to the forum and new to SQL, ASP.NET, etc. I am creating an intranet site for my company in VS 2005 and have run into a very annoying problem that I can't seem to solve. I have tried Googling it and came up empty. I have a database in SQL Express 2005 and my website will be accessing several tables within the database. I can retrieve info just fine and I can update, delete, etc just fine using gridview or other prebuilt tools, but when I add a few text boxes and wire a button to the SqlDataSource.Insert() command, I get a new record that is full of null values except for the identity key I have set. The kicker is that I am also using a master page and when I duplicate the web page without the master page link, everything works just fine. The following snippets show what I'm doing:<InsertParameters><asp:FormParameter Name="Name" Type="String" FormField="txtName" /><asp:FormParameter Name="Location" Type="String" FormField="ddlLocation" /><asp:FormParameter Name="Issue" Type="String" FormField="txtProblem" /></InsertParameters>Of course I match the formfields to the text boxes, create an onclick event for my button, the sqldatasource is configured correctly, it just doesn't work with the master page no matter what I do. Any help would be appreciated. Thanks

We have a rather large environment and have just a couple of boxes out there that we are getting cannot begin distributed transaction on inserts and updates but works fine on selects. Inserts and updates work fine outside the begin tran / commit so it's definitely DTC
We have checked the configuration on and the source box is set to No authentication required same for destination.
We have: Verified credentials running the service, changed them, same problem. Uninstalled and re-installed MSDTC per Microsoft instructions.
Have run all the tools for checking DTC DTCPing etc and followed those procedures which typically in the past has resolved any DTC issues. Other than swapping out the offending pc for a new one we are at a loss.

My question is how to get IDENTITY_INSERT Incriment Primary Key ID roll back when the application fails.
Using TransactionScope with single connection in DataObject. I am trying to insert row in two dataTable using its own tableAdapter (two tableAdapter).
I have Product table with ProductID primary key with incriment identity. and that ProductID is used to insert row in ProductHistory Table. Lets say Product table has the last ProductID=8 (8 rows) and the next ProductID will be 9.
When I insert row in both table and if the second table insert fails both gets roll back (which is good). but when I insert again another time the Product ID=10 not 9. Is there any way to roll back the ProductID in Product table so when i insert next time it has incriment number instead of gap.

What we've found is that when you have two reports where one navigates to the other, if you click on the second page of the second report, it takes you to the second page of the original report. If you navigate over to the subreport again and click for the second page, it works appropriately. This is definitely a no-go for production code and this may delay our ship date because I would think this is definitely undesirable.
Conditions:
ASP.NET Report Viewer using Remote Reports
Report that links to another report
Both reports return more than one page
Reporting Services installed
Steps to Reproduce:
Download the source code here.
Follow the directions (near the bottom of the post) to get the project set up.
Run it and click on a link in the first report to go to the second report.
Click the arrow for page 2 of the second report.
Notice how it takes you back to page 2 of the first report (this doesn't happen when you are in preview mode in the Reporting Services project and I don't believe it does this in a smart client application).
Click on a link in the first report to go back to the second report.
Click the arrow for page 2.
Notice how it takes you to page 2 of the second report.
Here is a link with source code and a more detailed explanation: http://geekswithblogs.net/robz/archive/2007/11/21/Reporting-Services-2005-BUG-Report-Linking-and-Paging---ASP.NET.aspx
So what I am looking for is both a workaround for now and if this is determined to be a bug, to be fixed in the next service pack.

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE

Is there a way to continue the execution of a script after an error occured after a BULK INSERT execution?
I tried this but is not working:

I am cleaning up a large database table that has Date keys instead of real DateTimes. To do this, I am running the following query...
UPDATE MQIC.DBO.OBSERVATION_F
SET MQIC.DBO.OBSERVATION_F.OBS_DATE = MQIC.DBO.DATE_D.ACTUAL_DATE
FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D
ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY
where Actual_Date is what is being stored, and the Date_Key is to be dropped.
The particulars are this -
Date_D table - 92,000 rows - 40 MB
Observation_F - 2,000,000 rows - 3.2 GB
This is being run on a remotedly hosted rack server with an AMD processor, 1 GB RAM, 60 GB harddisk space, 20 GB used.
SQL-Server 2005 Express - SP1
If I do the same query as a SELECT Statement,
UPDATE MQIC.DBO.OBSERVATION_F
SELECT MQIC.DBO.OBSERVATION_F.DATE_KEY, MQIC.DBO.DATE_D.ACTUAL_DATE
FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D
ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY
it runs to completion in about 15 min - during the entire time there is extensive used of CPU from Task Manager.
If I do the above statement, it seems to use lots of resources (50% +) for about 5 min, then falls to 5%. It just seems to sit there, for an hour + at which time I've killed the query.
This is actually the second time I tried this. The first time was on a different machine, with the P4, 3GB RAM, plenty of disk space, and using SQL-Server 2005 Standard - SP1. Exactly the same decrease in resources happened, and even though it ran several hours, no results.
Any thoughts here - not waiting long enough, memory leaks, etc.?
Thanks!

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

Hi all I'm using Sql server 2000 and sometimes i need to run my Queries in Query analizer before using them in my application just to test them...BUT most of the time when i run a query in query-analizer for second time ,query analizer populates the result (records) more quicker then the first time. Apparently it caches the query !!! i don't know but for some reasons i dont't want this , so how can i prevent Query-analizer from doing so?

Dear All,
I have created a table in my SQL server database, the problem i am facing is my insert query fails if i leave any form field empty (leave it blank). On my back-end table, only one field is mandatory, and others have been set with the constraint "allow null".
As per our business requirement, except one value is complusory while others are optional. If I enter all values in the form it works perfectly fine. Can you see in the code below - where am i possibly going wrong ?
<script language="VB" runat="server" > Sub Page_Load(Src As Object, e As EventArgs) If Page.IsPostBack Then Dim ConLath As SqlConnection Dim comLath As SqlCommand Dim insertcmd conLath = New SqlConnection("Data Source=SQLas;Initial Catalog=settle;User ID=sa;Password=password") ConLath.Open() insertcmd = "Insert into His_set values (@t_d,@s_p,@p_s,@v_oq,@i_oq,@v_qn,@i_qn,@v_qw,@i_qw)" comLath = New SqlCommand(insertcmd, ConLath) comLath.Parameters.Add(New SqlParameter("@t_d", SqlDbType.DateTime, 12)) comLath.Parameters("@t_d").Value = trade_date.Text comLath.Parameters.Add(New SqlParameter("@s_p", SqlDbType.Decimal, 8)) comLath.Parameters("@s_p").Value = sett_price.Text comLath.Parameters.Add(New SqlParameter("@p_s", SqlDbType.Decimal, 8)) comLath.Parameters("@p_s").Value = post_close.Text comLath.Parameters.Add(New SqlParameter("@v_oq", SqlDbType.Int, 8)) comLath.Parameters("@v_oq").Value = vol_oq.Text comLath.Parameters.Add(New SqlParameter("@i_oq", SqlDbType.Int, 8)) comLath.Parameters("@i_oq").Value = oi_oq.Text comLath.Parameters.Add(New SqlParameter("@v_qn", SqlDbType.Int, 8)) comLath.Parameters("@v_qn").Value = vol_qn.Text comLath.Parameters.Add(New SqlParameter("@v_qw", SqlDbType.Int, 8)) comLath.Parameters("@v_qw").Value = vol_qw.Text comLath.Parameters.Add(New SqlParameter("@i_qn", SqlDbType.Int, 8)) comLath.Parameters("@i_qn").Value = oi_qn.Text comLath.Parameters.Add(New SqlParameter("@i_qw", SqlDbType.Int, 8)) comLath.Parameters("@i_qw").Value = oi_qw.Text
Try comLath.ExecuteNonQuery() Catch ex As SqlException If ex.Number = 2627 Then Message.InnerHtml = "ERROR: A record already exists with " _ & "the same primary key" Else Message.InnerHtml = "ERROR: Could not add record, please " _ & "ensure the fields are correctly filled out" Message.Style("color") = "red" End If End Try

I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.

I have created a bulk insert query in SQL;
BULK INSERT TempTable FROM 'c:arcodeewdata.csv' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '')
which imports my csv data into the table no problem, but need some assistance on how to call this from a asp.net page.
I have created a file upload, which once successfully uploaded I would like to then call the BULK INSERT statement to import all of the data.
The pages are asp.net C# and a sql 2005 database.
Thanks

In my web page(.Net/c#) , I want to update few fields of a database table. The code is fine. The stored procedure through which I perform the execution is fine. I'm confidently saying this is because, if I try to do the update direclty while executing the stored procedure, it gets updated. I'm facing a weird problem while trying to update the fields from my web page. When I make an update and submit it, the first time it shows the updated value in the screen. But if I try to refresh it or redisplay the data ( I guess whenever it makes a trip to the database), the old values gets populated instead of the new values. I tried debugging it, but everything seems to be working fine. I looked up the execution in SQL Profiler, everything seems to be fine. I've no clue what's going on. I've proper permissions to make an update. So there is no permission issue. Could someone tell me how to handle this issue and what might be the possible problem which makes the values not update in the database?

Hello
I have a question about something odd happening with an insert query.
I am working on a password protected site and I want to moniter general student use. I have an on page load even which picks up their user id and the url and sends it to the database
Because my site is a beta site, I also want the users to be able to add their comments as and when they want, so I built a small feedback form on each page.
The quick feedback form has a panel to hide it until a user clicks on a radio button and this reveals a text box and a submit button.
However, since I have added this second sql connection with an insert, I now get an error message I was getting a connection string error when I tried to point at the connection string in the web.config file, so I put the full path in to the database and now I get an error message that says the conTrackUser has not been declared, but as you can see from the code it certainly has. So I'm beginning to thing that the error is something entierly different, but that's probably me being thick.
I've pasted the two insert blocks below, I can't see anything wrong with them, but then I'm mostly groping about in the dark with asp.net.
Is it not possible to have two insert commands on a page? That would be daft.
Here is the code.
Track and initilize the radio button and panel for the feedback:
Sub Page_Load(Sender As Object, E As EventArgs)
Dim UserID as String = session("UserID")
pnlQuickFeedback.Visible = False
If Not Page.IsPostback Then
Dim conTrackUser As SqlConnection

Hello
I've to write an trigger for the following action
When a entry is done in the table Adoscat79 having in the index field Statut_tiers the valeur 1 and a date in data_cloture for a customer xyz
all the entries in the same table where the no_tiers is the same as the one entered (many entriers) should have those both field updated
statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture
thank you for your help
I've never done a trigger before

Hi All,
Is it possible to refresh the web page when certain table data is updated? And I cannot use the auto-refresh feature. Thank you very much.
