Any suggestion is greatly appreciated.

I have been requested to add the sum of an interger field to the table header. I have the sum in the footer (which is very easy to do), but I cannot get the sum to appear in the table header.
I then set-up the stored procedure to run the sum, and place it into a dummy field. I still cannot add this field to the table header. Instead of printing the data for the dummy field (the correct total), it instead prints the actual field name on the report.
Is there anyway to place a sum in a table header on a SQL Server Report?
Let me know.
Thank you,
T.J.
I have a question regarding saving hashtags in another table. I have two tables with these columns:
Table1
ItemId, Name, Description (it may contains several hashtags like this example "hey I am an #example of this #question")
Table2
HashtagId, ItemId, Hashtag
So I want to detect #example and #question and put them in Table2. I'd like to create a trigger for table1 that if there was a hashtag, it added a record in table 2.
CREATE TRIGGER [dbo].[tr_Events_ForInsert_Hashtag]
ON Table1
FOR INSERT
AS
BEGIN
DECLARE @ItemId bigint
SELECT @ItemId = ItemId FROM inserted

Hi,
I have a table called "tblProducts" with following fields:-
ProductID(Pk, AutoIncrement), ProductCode(FK), ProdDescr.
So to the above table I have added a new field/column named "ProdLongDescr(varchar, Null)"
So, I need to populate this newly added column with specific values for each row depending on "ProductCode" which is different forevery row. The problem is that I have 25 rows.So instead of Writing 25 individual update scripts, is there a way in which single query will do the same job instead of writing one update query for each row ?. If so can some one guide me how to achieve that OR point to me a good resource.
Below are a couple of Individual update scripts I Wrote. "ProductCode" is different for all 25 rows.
Update tblValAdPackageElement SET ProdLongDescr = 'Slideshows' WHERE ProductCode = 'SLID'
And szElementDescr='Slideshow'
if @@error <> 0
begin
goto ErrPos
end
Update tblValAdPackageElement SET ProdLongDescr = 'CategorySlideshows' WHERE ProductCode = 'SLDC'
And szElementDescr='CategorySlideshow'
if @@error <> 0
begin
goto ErrPos
end
Thanks,

Hi,
I want to lock a table so others cannot lock it but able to read it inside transactions.
The coding I need is something like this: set implicit_transactions on begin transaction select * from table1 with (tablock, holdlock) update table2 set field1 = 'test' commit transaction commit transaction
I have tried the coding above, it won't prevent others from locking table1.
So, I changed the tablock to tablockx to prevent others from locking table1. But this will also prevent others from reading table1. So, how can I lock table1 so others cannot lock it but still able to read it?
Thank you for any help

Hi,all:
This problem almost drives me crazy, hope I can get some hints from you guyz!!!
Ok, here is the situation:
I wanna only one users 2 modify the data(update) from my page each time, and if at the same time, there are some other users connecting my database through .aspx page, they can only browse the data until the first users finish updating.
It seems I need to implement locking the database, but I am not sure how I am gonna do that using asp.net!!!
Thanx in advance!

I am having a VB application running for the SQL SERVER DB. The VB application is installed on the multiple of PCs in the network. Now when I am trying to fetch the same from all the different PCs simultaneously, its amazingly fast. But the issue comes when I am trying to update the same table (but different rows) from the different PCs simultaneously. The time taken is directly proportaional to the number of users. I am not getting what could be the problem? Can any one suggest me the approch? Is it some related to table / row / page locking? As all the connections are trying to update on the same table. I checked the isolation level. Its default, "READ COMMITTED". Kindly suggest...
Thanks in advance........

Hi,
I am working on a project which need to produce a sequential certificate number, Everytime I need a new certificate number, I need to find out what is the max number in the database and then the new certificate number just max+1.
But how can I block another
transaction to check what is max certi. number while this transaction is in the middle of writing the new certificate number(max+1) into database . Does ADLockOptimistic work in this case? Here is the code:
My database sql 2000.
cmdTemp.CommandText="Select max(certificateNumber) from product_table where certificateNumber<> 8888888"
set cert_info=Server.CreateObject("ADODB.RecordSet")
cert_info.Open cmdTemp, , AdOpenKeySet, adLockOptimistic
If Not cert_info.EOF then
certnumber=cert_info(0)+1
End if
cert_info.close
set cert_info=nothing
How can i give a table wise exclusive lock in MSSQL Server ?
I got the description but, How can I apply this ?
The sql :
LOCK TABLE <tablename> IN EXCLUSIVE MODE
is not working.
Is there any query/method to do this ?
Please help ...
thanks
About Exclusive locks
--------------------
Exclusive (X) locks are used for data modification operations, such as UPDATE, INSERT, or DELETE.
Other transactions cannot read or modify data locked with an Exclusive (X) lock. If a Shared (S) exists, other transactions cannot acquire an Exclusive (X) lock.
--------------------
I need to update a row but keep a lock on the table (so no one else can update it) while I do run some more code. In Oracle, it always locks whatever you update until you hit commit, but sql server works opposite. How do I tell it not to commit a statement, or how would I explicitly get a lock and then release it later?
View 4 Replies View RelatedI need confirmation from you SQL Server experts out there. Please let me know if the following works. Thanks!
This stored procedure gets a value and increments by 1, but while it does this, I want to lock the table so no other processes can read the same value between the UPDATE and SELECT (of course, this may only happen in a fraction of a second, but I anticipate that we will have thousands of concurrent users). I need to manually increment this column because an identity column is not appropriate in this case.
BEGIN TRANSACTION
UPDATE forum WITH (TABLOCKX)
SET forum_last_used_msg_id = forum_last_used_msg_id + 1
WHERE forum_id = @forum_id
SELECT @new_id = forum_last_used_msg_id
FROM forum
WHERE forum_id = @forum_id
COMMIT TRANSACTION
I have a query like this
SELECT TOP 1 * FROM ITAM_RAMS_STAGING
not getting value...seems like lock associated with that table
how to remove the lock if exists
I have multiple applications which can potentially update the same trigger simultaneously. Each application:
(1) Reads the contents of the current trigger
(2) Creates a new trigger based on the current contents
(3) Drops the trigger
(4) Creates the new trigger
I need to insure that once one application begins step (1), then no other application can start step (1) until step (4) has completed.
Any ideas on how this can be done? Some databases have a concept of locking tables explicitly, so for them, I can do:
(0) lock table foo;
(1) - (4)
(5) unlock table foo;
Is there such a concept in mysql or is there another way of accomplishing this?
Thanks,
Eric
Folks,
I have an update statement and it looks like it is holding exclusive lock on the table and does not release it until it completes. a PAGLOCK hint has been specified on the update statement and i think it is being ignored. It is a transaction database.so, other queries accessing that table has to wait for it to complete and thus causing timeouts.The Update statement is also causing high IO and CPU utilization. How do I
1) reduce the granularity level to prevent the locking
2)any ideas on optimizing the query?
Here is the query:
UPDATE Customers
SET IndexStart = TMP.IndexStart,
IndexPosition = TMP.IndexStart,
IndexStop = TMP.IndexStop,
IndexLevel = TMP.IndexLevel
FROM Customers AS C WITH (PAGLOCK)
INNER JOIN #tmp_IndexBCs AS TMP WITH (TABLOCKX) ON C.ID= TMP.ID
Thx

Hi All
We are facing atable lock issue , while running a SSIS package
We have two flows . one for insert and other for update into the same target table.
The update is done using a procedure.
We have disabled the lock table option in the target( in the insert flow)
The first set of records which come for updates flow fine.
But when the records start coming into the insert flow, the data flow stops.
Is this a table lock issue?
How do i set the commit interval at the update flow?
can someone lpease help me out of this situation
Thanka and Regards

I use proc handling special business logic (I also use constraints, indexes for that ;-)
Now I have a situation where I should check multiple rows with an proc.
Preventing multi-user issues I want to lock the table (yes, yes potential performance issue, but in this case there are few simultaneous jobs) - in Oracle I could lock the table, but what to do in SQL Server?
Maybe you have an better alternative, then let me hear ;-)
Or should I use "begin transaction"...

Hi!
I'm new in SQL and I´ve been the problem bellow:
I lock a record in one foreign table and automaticaly SQL lock the record that matches on primary table.
But this occours just in some primaries tables and not in all. I need that just the table that are of SELECT are lock. How can I do this?
Example:
** At open of the invoice:
SET ISOLATION LEVEL READ UNCOMMITTED
BEGIN TRANSACTION
SELECT * FROM INVOICE WITH (ROWLOCK UPLOCK) WHERE ( ID = 15 )
******* at the end of invoice:
INSERT INTO INVOICE ........
COMMIT TRANSACTION
END
******* The relationship are:
INVOICE <>> ITENS_INVOICE
ITENS_INVOICE <>> PRODUCTS
CUSTOMER <>> INVOICE
VENDORS <>> INVOICE
Just the INVOICE and PRODUCTS record´s involved in Transaction are lock. ( The CUSTOMER and VENDORS are not locked for example )
But I need that just INVOICE record be locked.
Thank´s for all and sorry my English.

Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
Please advice. Thanks a bunch.
