I feel like I read about a new ability in SSRS 2005 to be able to lock the position of a table's header row (when viewing through the report viewer) so that it does not scroll out of view when scrolling down long report. Now that I need it, I have not been able to find any information about it. Does anyone have any information about this feature or know if this feature exists?
View 1 RepliesI have a situation where for a given customer, their invoices need to be sequentially numbered, without gaps.
Customer A Invoice 1,2,3,4 ...
A-1
A-2
A-3
A-4
Customer B:
B-1
B-2
etc.
The issue is 2 people creating an invoice for the same customer at the same time. Currently I don't assign the Invoice number until the user hits 'Save'. At that time I query for max(invoiceno) against the customer key and simply add 1. it's the last operation prior to saving against the backend.
If 2 users hit Save at the exact time, I'm getting the same (duplicated) Invoice Number.
What suggestions/techniques do you have to resolve this? Would "locking" of the customer record and storing the last highest invoice there play a part?
Thanks,
Peter
I have a sql query

I have a report that I created and the report was working until I added some fields to a group footer row in a table.
My table has 5 group levels. I had information displaying in the 5th level header group and detail. It was working fine. Then I added some fields to the 4th level group footer. Now it displays only the Page header, Table header, and the 4th level group footer data.
What happened to the rest of the data?
All the cells and rows I want to display have the Visibility Hidden set to false. I tried removing the objects I added (to the 4th level group footer) and it still does not work. Is this a bug or did I set something that is hiding the data.
Thanks,

Gurus,
I am trying to execute this stored procedure when I try to change all occurences of a field in a table.
(
@Dept char(8),
@DDept char(8)
)
As
Set NoCOUNt On
Begin
Select '@DDept'
update phodept set fo_dept = @Ddept
where fo_dept = @Dept
update phone set fo_dept = @Ddept where fo_dept = @Dept
End
GO
The table/database is being used by others, generally in a read only mode.
via a VB 5.0 FE program.
The Stored procedure, when it is invoked, just hangs like it is waiting for exclusive use of the table.
Is there a way around it, without doing major surgery on the VB code?
Thanks.

Hello,
I am working on the implementation of a database for my company and I have
a simple (I hope) question to ask.
I have the following stored procedure that will be running when I want
(actually when I want to delete a customer).
Do not mind if you do not understand what this procedure does... ;-)
Actually the Level8View is a VIEW of a nested table
(CustomerData->CustomerData).
CREATE Procedure DeleteCustomer
@ClientID INT
AS
UPDATE Level8View
SET UpCode = Level2, Level1=Level2, Level2=Level3, Level3=Level4, Level4=Level5, Level5=Level6, Level6=Level7, Level7=Level8
WHERE Level1=@ClientID
UPDATE Level8View
SET Level2=Level3, Level3=Level4, Level4=Level5, Level5=Level6, Level6=Level7, Level7=Level8
WHERE Level2=@ClientID
UPDATE Level8View
SET Level3=Level4, Level4=Level5, Level5=Level6, Level6=Level7, Level7=Level8
WHERE Level3=@ClientID
UPDATE Level8View
SET Level4=Level5, Level5=Level6, Level6=Level7, Level7=Level8
WHERE Level4=@ClientID
UPDATE Level8View
SET Level5=Level6, Level6=Level7, Level7=Level8
WHERE Level5=@ClientID
UPDATE Level8View
SET Level6=Level7, Level7=Level8
WHERE Level6=@ClientID
UPDATE Level8View
SET Level7=Level8
WHERE Level7=@ClientID
DELETE FROM Customers
WHERE ClientID=@ClientID
GO
I checked this procedure and works perfectly.
What I want to do is to somehow lock the WHOLE TABLE (CustomerData) or the
view (Level8View) before the Update statements and unlock it after the
delete statements.
I do not want to do a Row by Row lock, or Page by Page lock since the updates
in this table occur in the whole table and during that operation I do not
want other threads to issue SELECT, INSERT or UPDATE statements.
Can someone answer me how I can lock and unlock the whole view or table
please?
I will appreciate it for your answer. Thanks.
Yours, sincerely

I have a SP for an e-commerce site that creates an order doing the following fashion:
begin
-Fill out some variables
*Critical Section
-Create Order number
-While loop select on order table and recreate if ordernumber already exists
-Insert into order table
*End Critical Section
-Insert into order lines table, address table, etc.
commit
The problem is the Create Order number and While loop used to be at the top and occasionally I would get duplicate order numbers if two submitted at the same time. I rearranged it to the above and it happens less now.
My question is if there is a way to put an XLOCK on the orders table only during the critical section lines. Also my understanding is that once the insert into orders is done that the server will hold a lock until the commit in case of rollback.? I don't want to XLOCK the whole SP if I don't have to. It is quick though.
Thanks
I need 2 unique sequential numbers to be stored in the same table. Obviously, for the first number I can use an auto-number field. For the second number, I would like to use a 2nd table with just 1 field that would only ever store 1 record. The idea being that if a user needs to generate a new unique number, they lock the 2nd table, lookup the current value, store the value in a variable for use, add 1 to the value of the number in the table, then unlock the table.
Presumably, I'd use something like this:
SELECT OrderNo
FROM tblUniqueOrderNumber (WITH TABLOCK)
Does this lock the table so no other users can read/write the table? If so, how do I unlock the table once I've updated OrderNo? What happens if another user then reads the table while it has a TABLOCK applied? I'm using SQL Server 2005 and the database is a multi-user database. I have a feeling I'm not going about this the best way possible, but I'd like to know how the table lock works eitherway.
hi
can i lock my table while doing an updation so that all others in n/w can insert into the table only after my operation is completed?
if a user attempts to save/update the 'locked'table, will he get an error message or will his application (using ADO) will wait till the table gets unlocked?
Can any one please tell me how to lock & unlock a table a from inside a store procedure using T-SQL

hi,
I am running a sql job that select data from one database (multiple table) and inserts into another database (1 table)
I have a problem with the way it is locking the tables I am selecting from !
my query is like :
insert into testdb.dbo.tabletest
select * from
livedb.dbo.tablex
inner join liveb.dbo.table1 on tablex.id=table1.xid
It seems to be locking the table and blocking other users from accessing the table.
suppose my question is why is the select locking the table ?
I want to insert values into a table and the same time select a valuefrom the same table.I insert a record of a parent type and use a function to create asubscriberType for the record.Next i insert a record of child type and want to select thesubscriberType from the parent record.This do not work when i useINSERT TABLESELECT ,Name,"function to generate subscribertype",.............I DO NOT WANT TO USE CURSOR!!
View 1 Replies View RelatedWe have a MS SQL database with an Oracle linked server 'ALTTEST'

im developing an application for my university final year project and i want to lock the table before the query executes to ensure that no other changes are allowed (sorry if im confusing)
So my question , really does anyone know how to do this and is it possible ?, for example in coldfusion a query is surrounded with cflock or something similiar.

Hi
Is a TABLOCK HOLDLOCK in a transaction the best way for locking a table for a brief period of time?
We need to get generate a unique serial number each time a certificate record is printed. We have in place a field called Field_SERIAL_NUMBER for each certificate record, which may be printed 1 time or 100 times. Each time it prints, we will insert a unique number into the Field_SERIAL_NUMBER field.
This is what I'm thinking to approach this.
- Create a new table called Table_SERIAL with one field called Field_NUMBER which has only 1 record set to 1.
- Every time a certificate is printed, we
1. Begin transaction
2. Select @number = Field_NUMBER from Table_SERIAL with a TABLOCK HOLDLOCK
3. Insert that number into the Field_SERIAL_NUMBER field in the certificate table
4. Increment @number by 1
5. Update Field_NUMBER with @number in Table_SERIAL
6. Unlock table
So, everytime the Field_NUMBER is pulled, it should be unique and incremented by 1.
Does this approach sound good?

Hi,
is there anyway i can run delete statements on an audit table that will not lock the whole table?
As it is an audit table, when i run the delete query, the whole application freezes until the delete query is complete.
the process is taking several minutes as the table is approx 40M rows, the where clause in the delete is indexed but thats it really.
any thoughts greatly appreciated by my system users!

Hi All,I am using a SQLTransaction to insert records into a table. At onetime, there are 5000 or more records to be inserted one by one. Ittakes some 20-25 mins for the entire process to run.Another application accesses the same table.As long as the insert process within the transaction isn't completed,the second application is not getting any response from the server. Ieven tried to run a SELECT on the table in SQL Query Analyzer while theinsert process was running and it also did not respond till the timethe insert process finished!Is this normal that a transaction is locking up a table? How do Iovercome it? I am using IsolationLevel.ReadUncommitted for thetransaction.If I do not run the process within a SQLTransaction, the second processor running the SELECT in Query Analyzer does not hang.Thanks,Sanjeev Mahajan

View 3 Replies View RelatedHi,
I have the following doubt about table lockinglocking in case of partitioning:-
Say we have 5 partition on the table Employee on the key Joining_Date and when we run 5 select queries on each of the parition in parallel will there be locking on the table when the 1st query is running or all the 5 queries can run in parallel. Basically, I am trying to see if parallelism and partitioning can work in sync or there will be locking at the table level if I don't specify any query hints?
Any help in this regard is highly appreciated.

I need some help. I am writing a report in SSRS 2005 that I then need to export to Excel. When I put a report header I would expect the header to not display in the Excel spreadsheet until the Print Preview or the Print. The report footer works just fine I put some text in the footer, and it shows up in the footer. The header though, shows up as a row in the Excel spreadsheet that then causes columns to merge. How do I get the report header to act like a page header?

We have a nightly script that drops and rebuilds a table. Problem is before the script has had a chance to complete the building of the primary key, it fails due to some other process gaining access to the table.
My question is this: how do I lock a table for the duration of the transaction.
Here is what I think would work:
SET ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
DROP TABLE <table>...
CREATE TABLE <table>...
INSERT INTO <table> WITH (TABLOCKX) ...
ALTER TABLE <table> ADD CONSTRAINT PRIMARY KEY ...
COMMIT
Any insight as to whether or not I am correct, or if I am not, what would be the correct way.
We currently have a large ETL import each night. There are lots of tables and some are quite large. If there is a problem with the nightly import, it is rerun during the day while users are running reports. The only updates to the tables is the nightly import.Currently the import does a BULK Insert and several INSERT INTOs. We are going to try to improve performance by adding a WITH (TABLOCK). But wonder if the TABLOCK will cause more locking, less locking, or be about the same. We do not have transactions batched. We insert all the records for a table in a single transaction.Â
Have found these references regarding TABLOCK, but I am confused what they mean, and how they differ from doing a BULK INSERT or INSERT INTO without TABLOCK.
TABLOCK - Specifies that a shared lock is taken on the table held until the end-of-statement. [URL] ....
Using INSERT INTO…SELECT to Bulk Load Data with Minimal Logging [URL] ....

Hi all,
We have an SSIS package which runs for around 30 min and it does a lot of things, now whenever this SSIS Package is run it is suspected that it is locing the table or records from the DB which it is reading the records, and indeed that system is having some fault that it is never able to remove that lock unless the DB restarts. In this source we only have a SQL Command and not a Table selected. Have anyone come across this problem? Any answers will be of great help.
Hi Friends,
There is a one header in the report, when I publish and hit the report in IE(internet explor) the header appears fine on first page when I go to next page this header does not appear.
But in mozilla the header is visible on every page of the report. so it is working fine in mozilla.
I donot why it is happening?
Your help is highly appreciated.

I have inserted a table in the layout. I want to create in the header of this table a field that sums up a set of values from a iif statement. So My expression is =sum(iif(Fields!aloc.value=2, Fields!balc.Value, 0)).
What I'm trying to do is sum all the values where aloc=2.
I Get an error saying The value expression for the textbox €˜textbox134€™ uses an aggregate function on data of varying data types. Aggregate functions other than First, Last, Previous, Count, and CountDistinct can only aggregate data of a single data type.
That data type of balc is Float.
What am I doing wrong or what do I need to do to fix this?

Hi all,
We have a scenario where we want to lock and unlock manually some rows in a table in SQL CE database .First the rows we need should be locked. By using a select query the locked rows will be read and processed in front end. Only if the process is completed in front end, manually I need to unlock rows which I have locked earlier. When rows are in locked state no body should be allowed to access that rows . ( should not allow anybody even to put a select query on that locked rows).
At the same time appending rows in the table should always be allowed.
Is it possible to achieve the above scenario?

I am quite new to MS SQL, and I want to read rows from a todo table, andwhen a row has been processed, I want to delete that row.Ages ago in MySQL I would probably have locked the table, select, processa row, delete a row, unlock the table.I have been reading through the documentation from MS SQL, but it's notclear what exactly I should do.Since I want to lock only one table in the select (the others just providedata, and are not modified), what's a good solution?--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html

I have a question regarding a locking scheme in MSSQL I hope you guys can help. In Sybase, I am able to specify datarow locking in DDL (ex. create table, alter table). Can I do the same in MSSQL or is there an equivalent option in CREATE TABLE statement in MSSQL? I came across a few articles in MSDN about datarow locking and it seems to me that MSSQL only allows locking through DML... Is that true? Thanks.
