Here's the scenario:
* I have a database with a table
* I have a C# program which displays information about the data in the database
* If the data changes in the database, I wish for the client to pick it up and report the change
Is there a way to have some form of 'Event Handling' where the client will react to UPDATE queries on a table?
My thanks in advance.
We are quickly moving from a small comapny to enterprise.As it happens we want to watch SQL server (our bread and butter is data) morecloely.Weely/daily/monthly reporting, etc.I am wondering if there is something like webtrends for SQL server. i.e. whatqueries were called (or even tables), what stored procedures, how much bandwidthwas used, what the average return time, how much data was returned (in rows andtotal size) etc.In fact, if this can be done by hour of the day that would be a bonus. (orconcurrent connections through out the day)Also, is there a tool much the same for Task Manager (Windows 2000) that cankeep a "long graph" for a day and save it somewhere (even better if it can tellme what query was run at spikes, etc).I am coming up empty looking for tools (is one built into SQL server?) but Ican't be the first person with this question.John Mosey |..X..|....|Brew-o-meterExalted Grand Puba: http://www.fantasybaseballnews.com/"...you look at slugging percentage and on-base percentage.

I am using an Execute SQL Task control flow to execute a stored procedure. It has both Input and Output Parameters. It is gettting compiled without any errors but there were no changes made to the database table. I have a doubt whether the parameter's values are getting manipulated properly. I want to check the value of the variable during execution. Is there any other way in which I can do it? I dont find a Watch Window. Please help me in doing this.

Here's the senario:
View 8 Replies View RelatedI have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:
Code Block
create table #IncomeAndExpenseData (
recordID nvarchar(5)NOT NULL,
itemID int NOT NULL,
itemvalue decimal(18, 2) NULL,
monthitemvalue decimal(18, 2) NULL
)
The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.
For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.
If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.
How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?

View 2 Replies View RelatedDoes anyone know what the best way to do mass updates in SQL server is? I am currently using the methodology suggested in this article

View 8 Replies View RelatedI'm developing a web app using ASP.NET and SQL Server 2005 Express. So far it's all been on my local computer, it hasn't gone live yet, so if I need to add a column to a table or make some other schema change I just do it right in Visual Studio, nice and simple. If I have to delete all the old content and start over, no problem. When I deploy it to a staging server I just overwrite the existing file with my new one, losing its data in the process. But soon enough I'll be deploying this to a public web server, there will be real live data in the db, people using it when I need to make updates.
What are some common strategies for updating the schema of a database on a live server?
It's obvious that when I need to update the db I'll have to shut down the site temporarily. But my biggest question is how to keep the existing data from the live db? I obviously can't overwrite it with my local copy. I want to overwrite its schema, without touching its data. How's that done?
Thanks for some advice!

Is it possible to perform a cascading delete and update using TRIGGERS on a table referenced by a foreign key constraint.?To be more specific.. if the primary key is deleted does the delete trigger on the primary table deletes the record in the foreign key table or does it return an error??
if possible please send us the T SQL Statements .

Dear MSDN Support,
Here i am back with an inquiry about the last process of Merge Replication between SQL Mobile 2005 and SQL Server 2005.
Well i have performed all the steps found in the tutorial of the SQL Mobile Edition Books Online, and everything went on so fine and smooth. Now when i deploy my application on the Pocket PC emulator all possible SQL queries work and modify the data only in the emulator, i had installed ActiveSync 4.0 and it synchronizes the SQL Mobile data with the SQL Mobile server only when i copy the database from the emulator to my desktop, and this way is not efficient to my project, i need a better way to synchronize the data between the database on the emulator and that on the SQL Mobile Server.
I'll be looking forward to getting your help as soon as possible.
Thank you for your attention.
Best Regards;
Hello!
We just upgraded to SQL Server 2005 from SQL Server 2000. The DB was backed up using Enterprise Manager and restored with SQL Server Management Studio Express CTP. Everything went as expected (no errors, warnings, or any other indicator of problems).
The DB resides in a DB Server (Server1) and the application we are running is a Client/Server system where the AppServer resides on Server2.
During the application's operation all read, create, and delete transactions work fine but no update works. When viewing details in Trace Log I see this message after attempting any update:
Could not find server 'Server1' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. (7202)
Any help is greatly appreciated,

Hi All,
I'm a relative novice on SQL Server and am a complete beginner at SQL, so am looking for a little help.
I currently use a DTS package to perform inserts / updates to a "production" table.
The DTS package transforms a comma separated file into a "temporary" table that is truncated / cleared before the load starts.
The temporary table has a column denoting Insert or Update. The production table is almost identical, however, doesn't contain the Insert / Update column. The DTS package then, depending upon the Insert / Update flag, either inserts data into the production table or updates data in the production table.
When the DTS package has completed, I'd like to be able to run an SQL Query that validates everything in the "temporary" table is identical to that in the "production" table, which it should be.
I have managed to do some queries to verify that everything has loaded / updated i.e. select primary_key from temporary table where primary_key not in (select * from production table), however, what I haven't been able to do is verify that all the columns on the temporary table match the values in the production table (excluding the Insert / Update flag).
I tried concatenating the columns in each table and comparing the concatenated values, however, this failed due to the different data-types, i.e. decimal, text etc.
Any help will be greatly appreciated.
Many thanks.
Cheers,
David
When one process has one record locked in Update-Mode then an other process can't update any other records on that table with some queries, other queries that access the same records (but with a different WHERE statement) will execute.
This problem occurs with SQL Server 2005, but it didn't with SQL Server 2000 (or any other database).
The problem:
-Process 1 locks a record in the table, and keeps it in Update-Mode, because the user is editing it. (Using OLEDB Pessimistic Cursor-locking)
-Process 2 wants to update an other record, buts gets a "Lock timeout" when using one query but not with another.
For example this query will work :
UPDATE gwseqnumber SET nextseqnr = 3 WHERE row_id = 110;
But this qeury will give me a "Lock timeout" :
UPDATE gwseqnumber SET nextseqnr = 3 WHERE name = 'REC_2';
But it is the same record!!
The record with name = 'REC_2' has the row_id = 110, both values are unique in the table.
The data:
The table [gwseqnumber] has the following CREATE statement:
CREATE TABLE GWSEQNUMBER
(
NEXTSEQNR INTEGER,
NAME CHAR (20),
ADMINISTRATIONCODE INTEGER,
FINDHIGHESTNUMBER CHAR (1),
CLOSEDYN CHAR (1),
ROW_ID INT IDENTITY(1,1) NOT NULL
);
CREATE INDEX KEY_1 ON GWSEQNUMBER (NEXTSEQNR);
CREATE UNIQUE KEY_2 ON GWSEQNUMBER (ADMINISTRATIONCODE, NAME, IDENTIFIER);
CREATE UNIQUE INDEX KEY_3 ON GWSEQNUMBER (ROW_ID);
Both KEY_2 and KEY_3 are unique, KEY_1 is not.
If I remove the index on the NEXTSEQNR column (the index named KEY_1) then both these queries will work, so it is obviously related to the index.
Altough the index is obsolete and can be removed from this table, it should not result in bogus locking errors.
Even when i removed the index not all the queries will work. (With work i mean not run into a locking error, while the record is not even locked.)
Solutions tried:
- Set the compaitiblity level of the databsae back to 80 (for SQL Server 2000 compatibility).
- I have already tried to disable Page-Locking on all the indexes of this table.
So why does the index lock my updates in SQL Server 2005?
And how do i fix it so my database does not run into these locks?
I am basically trying to update a table which reflects account transactions. Accounts get paid in full but occasionally balance payments can be reversed and I want to update the table to show this - I need to show which period the account was previously paid in full.I've created a simplified version of the scenario and below are a couple of examples of things I've tried that do not work.

I am looking to update a record from a previous row. So if there is a value of total goods in week 1, i want that value to carry forward to the value of goods in week 2. Is there any SQL as an example of the best way to accomplish this? I can query it using lag() which works great but i need the source data itself to update as the end-users are accessing the data via lightswitch, so when they save a change, i want the trigger (or whatever you recommend) to update the source table.

Just 2 -3 days back some windows updates got installed on the machine and guess what!!!!!! the sql server service just stopped working. The service wont start no matter what. I
have tried almost solution that i came across on the internet and it wont work out. I unistalled and reinstalled the server as but to no avail. The database engine now wont intall as the sql service wont start during the server installlation.
While browsing through the internet i didnt come across anyone with a similar problem! Am i the first one to be in such a situation

Hi,
I have the following problem: Within a VBScript, I use a component (written in C++ I think with use of ADO) for sending "Insert", "Update" Statements to an SQL Server 2000 for inserting, updating data. If I insert 100 - 120 Records in a Loop, all works fine. If I insert 1000 records, approximately 150 records will be inserted very quick, then the program pause fo approx. 8 - 15 minutes and then it proceed for the next 150 recs, pause for 8 - 15 minutes and so on.
If I use a SQL Server 2005 for the database, all works fine. The same happens with another customer and another program written in Visual Basic 6.0 with ADO. The access to SQL 2000 pause and with SQL 2005 all works fine. It seems to me that this is a problem with some buffers, timeout, or so. Has anyone an idea on what screw I can turn?
Thanks

Hi,

Is there any system table which track for date and time using stored procedure each individual records which has been last updated or newly created records??
Note : The application already created without lastModified date and each table... so, we don't want to modify the application or db.

Hello guys och dolls.
I have a DTS program in sql-server 2000 which worked to week 27 but not from week 28. During that time I was on vacation och no one else was working with the server.
The part which is the problem looks like this.
if exists (select * from dbo.sysobjects where id = object_id(N'[lenko7].[aviskydd]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [lenko7].[aviskydd]
GO
CREATE TABLE [lenko7].[aviskydd] (
[Col002] [varchar] (255) NOT NULL,
[linecount] [int] NOT NULL
) ON [PRIMARY]
GO
I have not changed owner.
I don't understand why this DTS package suddenly cant work because it has been working for a several years with no problems. The only thing a know is that we have updated windows 2000 cause of a critical updates Juli 13.
Is there anyone who has the same problem.

I have this doubt and want to be sure if my thinking is correct.
Lets consider 2 tables one with Fixed length columns (char) and other table with Variable length columns (Varchar).
The table with fixed length column will always allocate same size within a Page however, table with variable length column will allocate actual length of data within a page.
I think that updates happening on table with fixed length columns will have more possibility of InPlace updates at least from data length perspective, however updates on table with variable length columns will have more split updates from data length perspective.

How do I take what is in the CheckBoxList to the database and how does this relate to Stored Procedures?
