SQL Server 2008 :: Generate Increment Number With Conditional Restart
May 22, 2015
I need to create a script that adds an incrementing suffix to two columns, but restarts based on the value of another column. I found a similar question in the SQL Server 2000 forum, but it doesn't quite fit and also I'm working with SQL Server 2008 R2. The code below both creates a table with test data and tries to carry out the task. If you run this, you will see that the VISITNUM column has a value of UNS in row 4, UNS.1 in row 5 and UNS.2 in row 6. In row 7 it's V200, then in rows 8 and 9 it's UNS.3 for both. The same suffix gets applied to the VISIT column, but of course if I can solve this for VISITNUM then adding the suffix to VIST as well will be easy.
What I need is for row 8 to have UNS and row 9 to have UNS.1. In other words, any time the VISITNUM is UNS several times in a row, I need to add that ".X" suffix, but if a row has something other than UNS, I need to start over again the next time it's UNS again.
CREATE TABLE #testing(
KitID varchar(20),
SubjID varchar(20),
VISIT varchar(60),
VISITNUM varchar(20),
[code]....

Hi, in Access, I can use an Auto-Increment number for my primary key field. May I know how do I do that in SQL Express?
In addition, is there any tutorial on how to use SQL Express to generate customised unique numbers (such as membership number, Customer ID such as A001 where A is based on the customer's name while 001 is due to the fact that the customer is the first among those with names starting with A)?
Thanks a lot.

Is there a way to find the max number of sessions that were on a sql server since its last restart? I know how to get how many total connections there were since last restart, and the current number of sessions, but not the max number of sessions that were running since last restart. Also, opinion on the optinum number of allowable sessions, or a good way to figure out the balance?

I have a requirement to read a value from table and increment it by 1. There can be multi-threads doing the same operation and would need a ROW LOCK so that read and write both are atomic. How can i put an exclusive lock on the row before I read the value from the table.
CREATE TABLE [dbo].[tblOnboardingSequence](
[OnboardingSequenceID] [uniqueidentifier] NOT NULL,
[Name] [nvarchar](255) NOT NULL,
[NextNumber] [bigint] NOT NULL,
CONSTRAINT [PK_OnboardingSequence] PRIMARY KEY CLUSTERED(
[OnboardingSequenceID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
My Stored Procedure has below logic
DECLARE @NextNumber BIGINT
----------- Acquire row lock here
SELECT @NextNumber = NextNumber FROM tblOnboardingSequence WHERE Name = 'TPO'
UPDATE tblOnboardingSequence SET NextNumber = @NextNumber + 1 WHERE Name = 'TPO'
----------- Release row lock here
I would like to have a row lock for the row having Name "TPO" before SELECT query and release after UPDATE query.
What si the best way to deal with this?

It might be an old question but wanted to see, if we have any latest techniques (other than bcp).
SELECT Field1, Field2 FROM MyTable
If I want to export the output of the above query to a csv on a network folder? I would like to avoid usage of SSIS package or BCP (as user needs to get additional rights to execute bcp).

i need to generate documents for customers to sign automatically as sales staff enter their data into SQL. These are invoice style documents. I currently have word templates of the invoice documentation, i just need to be able to add the clients names, address etc into the relevant spaces for them to print off and sign.
I am good with TSQL and writing Stored Procs etc and can easily get the data ready - i just need to find a way to populate the templates in the right places and then save a copy for emailing.

I've been tasked to generate some test data (a few thousand rows) into a new table in a new database. This database is a whole new idea, so I can't write a query to pull pieces of data from other databases. I cannot consider any third party tools, such as what Redgate or Idera has to offer. I can't consider free tools such as what I've found on GitHub. I've been instructed to restrict myself to Visual Studio 2013 and whatever I can get that works within that.

Just wondering if there is any query which can give me report of locked account in SQL 2008. I know there are options like:-
1) Can go in ssms--security--account and right click and select status. This is applicable to individual account.
2)SELECT LOGINPROPERTY('accountid', 'IsLocked'). Also applicable to individual account
3) SELECT name,type_desc,is_disabled,modify_date,default_database_name from sys.server_principals order by type_desc
Generate the report but give the informatio as is_disabled. But I think is_disabled <> is_locked.

There is a SQL Server 2008 R2 SP3 Clustered Instance that has Transactional Replication. It is by no means a large replication setup in terms of data/article count. SQL Server was recently patched to SP3 and is current on Windows 2008 R2 Patches.
When I added a new article to replication (via 2014 SSMS GUI) it seems to add everything correctly (replication tables/procs show the new article as part of the publication).
The Publication is set to allow the snapshot to generate for just new articles (setting immediate_sync & allow_anonymous to false).
When the snapshot agent is run, it runs without error and claims to have generated a snapshot of 1 article. However the snapshot folder only contains a folder for the instance (that does have the modified time of the snapshot agent execution) and none of the regular bcp/schema files.
The tables never make it to the subscribers and replication continues on without error for the existing articles. No agents produce any errors and running the snapshot agent w/ verbose output provides no errors or insight into any possible issues.
I have tried:
- dropping/re-adding the article in question.
- Setting up a new Snapshot Folder
- Validated all the settings and configurations
I'm hesitant to reinitialize a subscriber since I am not confident a snapshot can be generated. Also wondering if this is related to the SP3 Upgrade, every few months new articles are added to the publication and this is the first time since the upgrade to SP3 that it has been done.

I have a SQL2008 database, running Standard Edition 64-bit, database owns by sa, connected to Management Studio using Windows Authentication mode. When I tried to generate scripts from a database, I got the following error messages:-
[Operation is not valid due to the current state of the object. (SqlManagerUI)]
which happened at one particular table. I have reviewed this table definitions are normal, and I could select data from it.
I couldn't find any information anywhere relating to this error messages, except that someone got it when they were trying to change the authentication mode or sa password.

Is there a way to make the primary ID as Identity Column to always be in order? For example, I have 5 rows with ID 1,2,3,4,5. If I delete record number 5 and then added another record, the ID shows up as 6 and not 5. Or if I delete record number 3, the next ID is going to be 6 instead of 3. I like to keep all my ID in order if possible and not skipping if that is even possible or should I use that practice.

I have a Column named 'Series' and a column named 'Linenumber'. They look like this:
Series Linenumber
234 NULL
234 NULL
235 NULL
235 NULL
234 NULL
234 NULL
235 NULL
235 NULL
236 NULL
236 NULL
236 NULL
And I want to run a query and make it look like this:
Series Linenumber
234 1
234 2
235 1
235 2
234 3
234 4
235 3
235 4
236 1
236 2
236 3
So basically I want Linenumber to be an increment column but to increment seperately for each value of Series. RDBMS is Microsoft SQL Server 2008.

Here is a piece of code I found in an application I'm supporting.
Problem: We're seeing duplicate numbers and I think this code may be the source of it.
At first glance I did not understand how it worked.
It locks a table <begin tran> , updates a number, reads that number, then commits. This code appears to work - it returns the newly added number.
My Question - How? How can this code return a value that is not "Committed" to the database yet. Please critique..... I have an alternate method, please comment on it as well. Thanks for your input.
--THIS IS WHAT I FOUND....
CREATE PROCEDURE sp_UpdateOrderNumber @customer int AS
DECLARE @NewOrderId int,
BEGIN TRAN
UPDATE CUSTOMERS
SET ORDER_NUMBER=ORDER_NUMBER + 1
WHERE COMPANY_ID=@customer
SELECT
If @@ERROR <> 0 OR @@ROWCOUNT <> 1 /* Check for Errors */
Begin
Rollback Tran
Return -999
End
SELECTORDER_NUMBER
FROMCUSTOMERS
WHERECOMPANY_ID=@customer
SELECT
If @@ERROR <> 0 OR @@ROWCOUNT <> 1 /* Check for Errors */
Begin
Rollback Tran
Return -998
End
COMMIT TRAN
My Newly suggested method. Using Implicit transaction.
I believe this is more "concurrency" friendly. Do you?
Begin loop until success
Read Number
Update to Number+ 1 WHERE number is the one I just read
If row was updated, use this new number and set success flag
Loop

Hi All,
Is there any option to get the velue of auto increment number before inserting record.
My problem is that I want to get the auto increment number, for this I am using MaxId function, but If i have deleted the some rows from table, I could not get the actual.
For example there are 20record s in the table I have delete the last 3 records now I have the last value of Identity is 17. When I used the Maxid function It gives me the 18 number. But I need 21.
How?
help required.
Thanks

I have a simple table with 4 columns
(idAuxiliarPF(BIGINT+PK), pf(BIGINT+FK), Data(DateTime), Descr(NVARCHAR))that has aprox. 50k rows.
I need to create a partition of the data to join to another table, the query that i have:
SELECT
ROW_NUMBER() OVER (PARTITION BY pf ORDER BY Data DESC, idAuxiliarPF DESC) AS RN,
pf,
Data,
Descr
FROM dbo.PFAuxiliar
WHERE Data <= GETDATE()This query takes around 40 seconds to return the results
If i remove the Descr column, the query it takes no time.
SELECT
ROW_NUMBER() OVER (PARTITION BY pf ORDER BY Data DESC, idAuxiliarPF DESC) AS RN,
pf,
Data
FROM dbo.PFAuxiliar
WHERE Data <= GETDATE()I have two indexes, Clustered (idAuxiliarPF), NONClustered(pf).
How can i improve the performance of this query?

I have a new problem with doing a restore of a number of databases using powershell. The script I'm using is based mainly on this one (Part 2 in particular): [URL] .....
The problem I'm having is around the RedgateGetDatabaseName function. My hunch is that its down to the different version of red gate and how sqlbackup works. Basically when the call is made to the function it is returning both the Database Name and the number of row's that the SQL command in the function has ran. I've tried to include a SET NOCOUNT ON at the start of the SQL command in the function but its still returning the now count.

How to get the result similar to Ex2, instead of Ex1. (ie., case-number is in sequential order then no need to break), And it should suit large dataset, I will finetune, if any performance issue.

I have a table of Customers & their data in about 20 Columns.
I have another table that has potential Customers with 3 Columns.
I want to append the records from Table 2 onto Table 1 to the Columns with the same names.
I've thought of using UNION ALL or Select Insert but I'm mainly stuck on the most efficient way to do this.
There is also no related field that can be used to join the data as these Customers in table 2 have no Customer ID yet as they're only potential Customers.
Can I just append the 3 columns from Table 2 to the same 3 columns in table 1?
