UPDATE With A DataList

Jan 20, 2006

Hi,
I'm having some troubles getting my UPDATE to work with my DataList control.  I am trying to get Optimistic Concurrency working, but i'm getting an exception stating that the dictionary for oldValues is empty.  I understand this is referring to the original values it compares with before performing the update, however, my question is how do I fill this dictionary in with the original values?
I have included a code sample of the sort of thing i am trying to achieve, it is just a simplified example of how I am trying to UPDATE the underlying data source.  Am I on the right track?  What do I need to do in order to get this to work?
Thankstrenyboy

Update On Machine Runs Immediately, Update On Linked Server Takes 8 Minutes

Jan 2, 2008

What's up with this?

This takes like 0 secs to complete:

update xxx_TableName_xxx
set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159

where enc_id in

('C24E6640-D2CC-45C6-8C74-74F6466FA262',

'762E6B26-AE4A-4FDB-A6FB-77B4782566C3',

'D7FBD152-F7AE-449C-A875-C85B5F6BB462')

but From linked server this takes 8 minutes????!!!??!:

update [xxx_servername_xxxx].xxx_DatabaseName_xxx.dbo.xxx_TableName_xxx
set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159

where enc_id in

('C24E6640-D2CC-45C6-8C74-74F6466FA262',

'762E6B26-AE4A-4FDB-A6FB-77B4782566C3',

'D7FBD152-F7AE-449C-A875-C85B5F6BB462')


What settings or whatever would cause this to take so much longer from the linked server?

Edit:
Note) Other queries from the linked server do not have this behavior. From the stored procedure where we have examined how long each query/update takes... this particular query is the culprit for the time eating. I thought it was to do specefically with this table. However as stated when a query window is opened directly onto that server the update takes no time at all.

2nd Edit:
Could it be to do with this linked server setting?
Collation Compatible
right now it is set to false? I also asked this question in a message below, but figured I should put it up here.

SQL Server 2000 - Issue W/ UPDATE - Single Row Update Returns 2 Different Messages

Nov 11, 2007

I am hoping someone can shed light on this odd behavior I am seeing running a simple UPDATE statement on a table in SQL Server 2000.  I have 2 tables - call them Table1 and Table2 for now (among many) that need to have certain columns updated as part of a single transaction process.   Each of the tables has many columns. I have purposely limited the target column for updating to only ONE of the columns in trying to isolate the issue.  In one case the UPDATE runs fine against Table1... at runtime in code and as a manual query when run in QueryAnalyzer or in the Query window of SSManagementStudio - either way it works fine. 
However, when I run the UPDATE statement against Table2 - at runtime I get rowsaffected = 0 which of course forces the code to throw an Exception (logically).  When I take out the SQL stmt and run it manually in Query Analyzer, it runs BUT this is the output seen in the results pane...
(0 row(s) affected)
(1 row(s) affected)
How does on get 2 answers for one query like this...I have never seen such behavior and it is a real frustration ... makes no sense.  There is only ONE row in the table that contains the key field passed in and it is the same key field value on the other table Table1 where the SQL returns only ONE message (the one you expect)
(1 row(s) affected)
If anyone has any ideas where to look next, I'd appreciate it.
Thanks

How To Correctly Update A Table Which Values Can Be Either Inserted/updated/deleted On Update?

Feb 16, 2006

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

SQL Server 2008 :: Update Null Enabled Field Without Interfering With Rest Of INSERT / UPDATE

Apr 16, 2015

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

Stored Proc Won't Update From C# .NET Code, But Will Update When Testing On Its Own.

Jul 23, 2006

I'm having a strange problem that I can't figure out. I have an SQL stored procedure that updates a small database table. When testing the Stored Procedure from the Server Explorer, it works fine. However, when I run the C# code that's supposed to use it, the data doesn't get saved. The C# code seems to run correctly and the parameters that are passed to the SP seem to be okay. No exceptions are thrown.
The C# code:
   SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["touristsConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("fort_SaveRedirectURL", conn);
cmd.CommandType = CommandType.StoredProcedure;
Label accomIdLabel = (Label)DetailsView1.FindControl("lblID");
int accomId = Convert.ToInt32(accomIdLabel.Text);
cmd.Parameters.Add("@accomId", SqlDbType.Int).Value = accomId;
cmd.Parameters.Add("@path", SqlDbType.VarChar, 250).Value = GeneratePath();
try
{
conn.Open();
cmd.ExecuteNonQuery();
}
catch(Exception ex)
{
throw ex;
}
finally
{
conn.Close();
}
 The Stored Procedure:
  ALTER PROCEDURE developers.fort_SaveRedirectURL
(
@accomId int,
@path varchar(250)
)
AS
DECLARE
@enabled bit,
@oldpath varchar(250)

/* Ensure that the accommodation has been enabled */
SELECT @enabled = enabled FROM Experimental_Accommodation
WHERE Experimental_Accommodation.id = @accomId

IF (@enabled = 1)
BEGIN
/* Now check if a path already exists */
SELECT @oldpath = oldpath FROM Experimental_Adpages_Redirect
WHERE Experimental_Adpages_Redirect.accom_id = @accomId

IF @oldpath IS NULL
BEGIN
/* If Path already exists then we should keep the existing URL */
/* Otherwise, we need to insert a new one */
INSERT INTO Experimental_Adpages_Redirect
(oldpath, accom_id)
VALUES (@path,@accomId)
END
END
RETURN

Update Function: Why SQL Server Update An Empty String With 0?

May 13, 2008

I'm new to this forum.
This 'problem' has occured many times, but I've always found a way around it.
I have pages with datagrids, in which a user can edit a certain fields and then update the tables with new data. Lets say when a user edit a Name field and a money field. If he/she left those two fields blank, the table is automatically updated with a <null> (for the name field) and a 0 (for the money field.) Both these columns were set up to allow Null values.
Anyone has an idea why they were updated that way? And is there like a standard on how the data types are updated if a field is left blank?
Thank you very much.

Seperate Date And Time Merge; Done At SQL Update Or C# .NET Then Update

Feb 18, 2006

I do realize that his could be posted in a few spots but I think the answer is in the SQL.
I have a ASP.NET page, with a SqlDataSource, Text Box and Calendar Controls. I have the textbox and calendar controls eval'ed to the same sql data source DateTime Field. The text box is formatted eval to small time and the calendars eval has no formatting.
ex:
<asp:TextBox ID="START_TIME" Text='<%# Eval("EVENT_START","{0:t}") %>' runat=server Width=200></asp:TextBox>
I want to merge the two controls; one has the date the other has the time when I update the pages data to the SqlDataSource field EVENT_START. I've tried a couple of methods, but I would like some other opinions. As Sql server only supports date and time together I am storing the two together.
I could merge the two together in the code behind on the update button's event handler or merge the two during the update query using parameters.
Not that I could get an illegal date for the calendar control, but I could get garbage from the textfield time. So I still would have to do validation on the text field before the SQL server could do the update.
There's a few ways to go about this, so I was wondering if anyone else has figured out an elegant way to handle it.

hi!

I have a big problem. If anyone can help.

I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.

I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.

But i don't know exactly how to do the coding for this?

Is there any other way to do this?

can DBCC help to retrieve this info?

Please advise me how to do this.

Thanks in advance.

Transact SQL :: Firing After Update Trigger - On Table Row Update

Jul 8, 2015

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
 
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),

I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.

I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

Stored Procedure - Update Statement Does Not Seem To Update Straight Away

Jul 30, 2007

Hello,

I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.

I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?

UPDATE AC
SET CustId = Left (CustomerId,10),
CustName = Left (CustomerName,25),
Addr1 = Left (Address1,25),
Addr2 = Left (Address2,25),
City = Left (ca.City,15),
Region = Left (State,2),
PostalCode = Left (Zip,5)
FROM RIO.dbo.tblArCust AC INNER JOIN
(SELECT CustomerCode, MAX(LastUpdatedDate) MaxDate
FROM COFFEE.dbo.vueCustomerAddress
GROUP BY CustomerCode) V
ON V.CustomerCode = AC.CustId
INNER JOIN COFFEE.dbo.vueCustomerAddress CA
ON CA.CustomerCode=V.CustomerCode AND
MaxDate=LastUpdatedDate
WHERE CA.addresstypeid = 1

UPDATE Query To Update One Table From Another

Sep 15, 2001

I'm looking for a query that can "batch" update one table from another. For example, say there are fields on both tables like this:
KeyField
Value1
Value2
Value3
The two tables will match on "KeyField". I would like to write one SQL query that will update the "Value" fields in Table1 with the data from Table2 when there is a match.

UPDATE Trigger Issue When Using UPDATE

May 30, 2008

I am trying to update a fields with an UPDATE statement but I keep getting the error message when I run the query.

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

I have this Update trigger that I know is causing the error message because I guess it's not built to manage multi-row updates.

Can someone help me re-write it. I also tried using the WHERE p.ID = p.ID but when I do that it modifies all rows in the modifieddate column instead of just the cells/rows that I'm updating

ALTER TRIGGER [dbo].[MultitrigCA]
ON [dbo].[ProdDesc]
AFTER UPDATE
AS

SET NOCOUNT ON

IF UPDATE (codeabbreviation)
UPDATE p
sET p.ModifiedDate = GETDATE()
FROM ProdDesc AS p
WHERE p.ID = (SELECT ID FROM inserted)

INSTEAD OF UPDATE Trigger To Hold Update

Apr 3, 2008



hi!

i have a database with about 20 tables. i appended to each table a column "UpdatedOn", and i want to write a trigger to set the date of the update date in that column, using a trigger.

i want to avoid the trigger launching for the last column (UpdatedOn).

how can i detect the rows that changed, and modify only the update date/time?
i read something about TableName_Inserted and TableName_Deleted, but i would prefer to copy as generic as possible the data from there, meaning, not to write column names in my script.

another idea i thought about was to prevent the trigger executing if no other column except for UpdatedOn changed, but... i encounter some trouble, when i try to pass column name (as string) to UPDATE() function.(Error: Expecting ID or QUOTED_ID)

thank you in advance.

SQL Server 2012 :: Update Statement Will Not Update Data Beyond 7 Million Plus Rows Out Of 38 Millions Rows

Dec 12, 2014

I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).

SET rowcount 10000
UPDATE [dbo].[CC_Info_T]
SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v'
WHERE [Acct_Num_CH] IS NOT NULL
WHILE @@ROWCOUNT > 0
BEGIN
SET rowcount 10000
UPDATE [dbo].[CC_Info_T]
SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v'
WHERE [Acct_Num_CH] IS NOT NULL
END
SET rowcount 0
