SQL Server Auto Increments?
Aug 7, 2005I have a table that consists of an invoice number, the ordering user's customer number, and current shipping status of the invoice.
What I would like is for the invoice number to auto increment whenever I insert into the table. I'm using SQL Server, but I can't find something to check (or whatever) in Enterprise Manager.
I'm certain it's possible, I just have no idea how. Please help!
Cheers,

Group By Time Increments
Mar 24, 2008Hello
I am trying to pull data from a table. I would like to group this dataset by a datetime field.
The result I want is for the records to be grouped together by their create time ( in this case using half hour increments.) All records created from the first half hour get grouped together, all records from the second half hour get grouped together etc. This dataset will contain data from a 24 hour time period (48 groups of data). What is the best way to accomplish? Do I need to use a cursor to accomplish?
Thanks
SQL 7 High Page Faults/sec Compared To 6.5 ?
Aug 11, 1999I am running an application on one NT Server, running against SQL Server 6.5 sp 3, and SQL 7 with sp1 applied.
The application is a 'data migration' type application - ie heavy insert and update workload - against many (50+ tables) with many different SQL statements.
The SQL 7 server is configured with 'floating' memory.
On SQL 7 - I am experiencing very high page faults/second for the sqlservr process - sometimes peaking at over 1,000. I was under the impression any number greater than 10 indicates a problem with system performance.
The same application, same data, same NT configuration etc against SQL 6.5 does not page fault. SQL Server 6.5 completes the work faster than 7.
Could anyone help me understand what's going on ?
Thanks in advance.
Perfmon - Process:page Faults/sec
Jun 13, 2000My question is, My perfmon counters reads anywhere between 0 and 1200 with the average being around 250 faults/second.
My concern is my memory max size being too large, I have 4gb ram, SQL reports usage at 2.9 GB, my max mem size is 3.9 gb, should I maybe set my SQL server to use a fixed memory size of 2.9 gb?
Thanks in advance
Pete Karhatsu
Copied from SWYNKs' article:
Process: Page Faults/sec
If this value is greater then 0 then the SQL Server process is producing soft page faults and as a result CPU overhead. Try setting the working set size value to be as close to the SQL Server's memory allocation.

MS SQL 2005, .NET, Logins/sec And Page Faults
Jul 25, 2006Hi, all.We have a couple of pathological sql servers that have lots and lots ofpage faults per second, up to 4000. Our client programs are written inC#/.NET 1.1 and utilizes connection pooling.Some of the client programs seems to log in hundred of times persecond, as reported by perfmon->.SQLServer:GeneralStatistics->Logins/sec. Stopping the client programs reduces thatnumber significantly.We've done code reviews of the client programs and they look OK.Monitoring .NET connections&pools does not show anything suspicicous.We're currently rewriting the clients to use one db connection insteadof the pools, but that takes some time and may introduce bugs. Doesanyone know why we have these problems and/or why logins/sec is sohigh? I'm thinking "bugs in the .NET client", but really have noidea...One thought I had was that the Page Faults reported for sqlsrv.exe isrelated to memory mapped IO and therefore can be ignored. Right orwrong?Any thoughs/pointers/ideas, even wild guesses, are most welcome.BjørnPS: The server memory is fixed at 1.5GB out of 2GB physical ram,clients run on the same machine and use TCP/IP comm.(I know...) Thehost itself is not paging.

View 1 Replies View RelatedHow To AVG Values For One Hour Of Five-minute Increments?
Feb 18, 2008Hello all,
I have the following very simple SQL Query:
SELECT TOP (100) AutoNumber, Date, ZNT, SAT, RAT, RH
FROM HV_Values
ORDER BY Date ASC
This shows the top 100 entries for a table (where there is a date entry every 5 minutes). Here's five sample records:
1 12/4/2006 4:12:11 PM 67.13 70.50 71.56 8.23
2 12/4/2006 4:17:11 PM 67.13 70.50 71.56 8.33
3 12/4/2006 4:22:11 PM 67.19 70.69 71.69 8.19
4 12/4/2006 4:27:11 PM 67.19 70.63 71.69 8.18
5 12/4/2006 4:32:11 PM 67.19 70.69 71.75 8.05
What I'd like to do with the sample query above is take an AVG for one hour for the values ZNT, SAT, RAT, RH...like I stated the records are every five minutes in the table, I'd like to create 60 minute AVGs.
Any ideas or sample queries I can work with?
Thank you very much! gad1
Identity Column Value Increments By 2 Rather Than 1 On Insert
Jul 26, 2007I have an issue with a stored procedure activation on a service broker queue. The activation stored procedure simply RECEIVES the top message and then INSERTs a row into a table with an identity INT column. Each row inserted has the identity column value incremented by 2 rather than 1. Only one row is inserted in the table.
If the activation is set to OFF and then manually calling the original stored procedure the insert works fine and the identity column value is only incremented by one.
Do you have any suggestions on why the identity column value increments by 2?
Thanks.
SQL Server 2000 Cluster - Excessive Page Faults
Jul 31, 2007We are running SQL Server 2000 Enterprise Edition on a 2-node cluster with IIS/ASP.NET front-end hosting 150-200 active connections. There is a SVCHOST process running under LOCAL SERVICE account - hosting the Remote Registry process that is using only 4,200K but is page faulting 200-500 times per second. I realize this process is used for failover, but the page fault seems excessive. Any thoughts on this?
The servers are running Windows Server 2003 with 4 processors and 4gb RAM.

View 6 Replies View RelatedBCP Into An Indentity Field
Jun 15, 2000Hi folks!
I need to populate a table having an identity field with data (basically I want to make a copy of a table with identity column on another server). When I use BCP to insert data then the values in the identity field is not the same as in the data file but gets incremented from the original.
eg. if the records in the flat file are-
1, 'test1'
2, 'test2'
Now if i insert this into the table (say the last identity value was 100) then rows get inserted as-
101, 'test1'
102, 'test2'
Is there any way by which I can retain the values of the identity column to be same as in the file?
Thanks!
Indentity Column

I would like to reset the identity without droping the table. I'm using

Jul 20, 2005I'm doing a data transfer from Access to SQL Server, I wish to keep theidentity column (autonumber) values as all the data is already related. Itried the first table append query including the identity column, it worked.Was this fluke? Will it always work? I was under the impression that I wouldhave to issue a "set identity_insert on" before doing this. The SQL databasewill have absolutely no data before the transfer routines are run.

Using The Indentity Column
Feb 22, 2008
As an example I have three tables
Table1
ChildName (nvarchar)30
ChildID (INT) Set as €˜IDENTITY€™
Table2
ParentName(nvarchar)30
ParentID (INT) Set as €˜IDENTITY€™
Table3
ChildID (INT)
ParentID (INT)
I have the following code.
Dim dbcnn As SqlClient.SqlConnection = New SqlClient.SqlConnection(dbsettings.getDatabaseString)
Dim dbcmd As SqlClient.SqlCommand
dbcmd_AddDriverRoute = New SqlClient.SqlCommand("usp_Insert", dbcnn)
dbcmd.CommandType = CommandType.StoredProcedure
dbcmd.Parameters.AddWithValue("@ChildID ", cmb_child.SelectedItem)
dbcmd.Parameters.AddWithValue("@ParentID ", "@@IDENTITY")
dbcnn.Open()
dbcmd.ExecuteScalar()
dbcnn.Close()
basically what I want to do is when a child is added I want to be able to insert ParentID (INT) Set as €˜IDENTITY€™ value into table3 ParentID (INT) .
I have my sql statement in place I am not sure how to take an identity value stored in the db.

Is It Possible That DTS Skipped Indentity Attribut
Sep 11, 2006I imported a table using DTS.
I run SQL statements in my original server database. It works well.
But when I run the same instructions within a stored procedure in my new workstation where I improrted the table I get this error:
Server: Msg 515, Level 16, State 2, Procedure InsertFichierPrix, Line 11
Cannot insert the value NULL into column 'Id', table 'myDBLive.dbo.FichierPrix'; column does not allow nulls. INSERT fails.
The statement has been terminated.
Here is the SQL statements that I run on the original Database:
insert into fichierprix(nomfichier, version, descriptionfr, typeclient,....) values(@NomFichier,'Actuelle', @NomFourFr, 'MembreAcheteur', ....)
And here is my SP that I run on the new imported database:
CREATE PROCEDURE InsertFichierPrix @NomFichier varchar(50), @NomFr varchar(50),@NomAn varchar(50)
AS
declare @NomFourFr varchar(50)
declare @NomFourAn varchar(50)

Ordering Of Newly Added Indentity Value ?
Aug 1, 2007Hi There
Can anyone tell me how an identity column decides what number to give which row.
I always thought that it was in order of the clustered index.
But i have found the following:
If you have Table A with a clustered index(not unique) say on the first 3 columns.
If the table is empty and you add an identity column, then afterward load it with data the value of the identity column seems to match the clustered index.
But if the table has no identity column and it is filled with data, and then you add an identity column the number for the identity column seems to be all over the place.
So basically how does a newly added identity column know what number to give each row, what if the clustered index is not unique? Is it random ?
Thanx
