I'm involved in the developement/maintanance of a database that has a lot of stored procedures. The procedures are constantly developed and it would be good to have some kind of version handling connected to them.
Is there any way to achive this?
/Lars
I've got the folloing stored procedure
ALTER PROCEDURE AddUserData
(@login varchar (8),
@password varchar (8),
@fullName varchar (50),
@RoleID Int,
@statusID Int)
AS
if exists
(SELECT login, @errorReturn
FROM tbEmployee
WHERE login = @login)
return 55555
Else
INSERT INTO tbEmployee (login, password, fullname, RoleID, statusId)
VALUES (@login, @password, @fullName, @RoleID, @statusID)
RETURN @@error
the function that calls this stored procedure is this
Public Shared Function InsertUserData(ByVal login As String, ByVal password As String, ByVal fullName As String, ByVal StatusID As Integer, ByVal RoleID As Integer)
' Create the connection object
Dim connection As New SqlConnection(connectionString)
' Create and initilise the command object
Dim command As New SqlCommand("AddUserData", connection)
command.CommandType = CommandType.StoredProcedure
command.Parameters.Add("@password", SqlDbType.VarChar)
command.Parameters("@password").Value = password
command.Parameters.Add("@login", SqlDbType.VarChar)
command.Parameters("@login").Value = login
command.Parameters.Add("@fullName", SqlDbType.VarChar)
command.Parameters("@fullName").Value = fullName
command.Parameters.Add("@roleID", SqlDbType.Int)
command.Parameters("@roleID").Value = RoleID
command.Parameters.Add("@statusID", SqlDbType.Int)
command.Parameters("@statusID").Value = StatusID
' Open the connection
Try
connection.Open()
command.ExecuteNonQuery()
Finally
connection.Close()
End Try
End Function
now I'm trying to get ahold of the return value from the stored procedure so I can output a message to the user in a label control.
e.g the soted procedure checks to see if a user already exists if it does it returns 55555. how can I get ahold of this 55555 and place it in a variable in the function so I can then send it to another error function to display the approperate lable message ??
thanks all
I have a requirement that requires detection of rows deleted/updated byother processes. My business objects call stored procedures to create,read, update, delete data in a SQL Server 2000 data store. I've donea fair amount of research on concurrency handling in newsgroups andother resources. Below is what I've come up as a standard forhandling concurrency thru stored procedures. I am sharing with everyoneso I can get some comments (pro/con) regarding this approach and see ifanyone can find any holes for this solution.Below is the DDL, DML and a Stored Proc demonstrating the approach. Iam using a rowversion column for concurrency checking. Another approachthat is less intrusive (doesn't require having a rowversion column inall tables) is using checksum. I may eventually use checksum but theprocess flow should be almost identical. Looking forward to anyone'scomments.Thx, BZ--xxxxxxxxxxxxxxxxxxxxxxxxxxx--IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name ='ApplicationUsers')BEGINPRINT 'Dropping Table ApplicationUsers'DROP Table dbo.ApplicationUsersENDGOPRINT 'Creating Table ApplicationUsers'GOCREATE TABLE dbo.ApplicationUsers(LoginName varchar (20) NOT NULL Primary Key,LoginPassword varchar (50) NOT NULL,LoginAttempts int NOT NULL default(0),EmailAddress varchar(25) NOT NULL Unique,DataVersion rowversion NOT NULL)GOIF EXISTS (SELECT * FROM sysobjects WHERE type = 'P' AND name ='UpdateUser')BEGINPRINT 'Dropping Procedure UpdateUser'DROP Procedure dbo.UpdateUserENDGOPRINT 'Creating Procedure UpdateUser'GOCreate Procedure dbo.UpdateUser@loginName Varchar (20),@loginPassword Varchar (50),@loginAttempts Int,@emailAddress Varchar(25),@dataVersion Rowversion OutputAs/************************************************** ****************************** Name: dbo.UpdateUser** Desc: Updates an Application User instance**** Parameters:** Input** @loginName** @loginPassword** @loginAttempts** @emailAddress** @dataVersion. row version used for concurrency control.**** Output** @dataVersion. updated row version used for concurrencycontrol.**** Return** 0 for Success.

Is there any way to restore a database of higher version to lower version.
E.g. I have created a database in sql server 2012, created some tables & procedures in that.I took Full backup of that database. Can I restore it to sql 2008r2 or any lower version.
I know direct restore is not possible, I have to use either import or export option or generating script,but i want to know is there any easy step to do so.

Hi all,
Since some analysis services features are only available in Enterprise version , I have to upgrade my SQL 2005 server from standard edition to enterpise edition.
So I uninstall originial standard version of analysis service and install a Enterprise version. However, the analysis service is still a standard version after installation.
Is it possible to keep data engine as standard version and install a enterprise version of analysis service?
Thank you very much

Hello,I have been searching and reading a lots of information on the microsoft website about the different version of SQL server, but still can not make my decision.In term of performance, is there a real big difference between the workgroup and the standard version? The workgroup is limited to 3 GB of RAM while the standard is unlimited, would that really change the performance if my server has 16Gb or RAM?The price difference is pretty substantial so if could only have to buy the workgroup , it would be better.One more question, regarding the type of licence, my server has 2 processors, could I avoid buying 2 licences and get the Server plus CAL instead. I am using this server to host 4 web-application running on SQL server. Each database is about 15 MB.Thanks in adavance for your advises.Arno
View 3 Replies View RelatedI am wondering if it is possible to change from SQL Server Enterprise Evaluation Version to Developer Version. The reason is because the Enterprise Evaluation version expires after 180 days. So if I create reports and cubes in Enterprise Evaluation I can import them into Developer Edition right? Should I remove the Enterprise Evaluation version after 180 days or leave it then install Developer Edition?

Ninety-five percent of the time it runs just fine, but every so often the job fails and I get the following set of error messages in the log file.

I have received the error message "Package migration from version 8 to version 6 failed".I have developed a SSIS package with Visual Studio 2013 which gives me PackageFormatVersion of 8. I then deploy my package to the ssisdb catalog that is running on a SQL Server 2012, this works fine but when I try to execute the package the error arises…due to SQL Server 2012 has a PackageFormatVersion of 6 and it can’t run something that has a greater version.I haven’t seen any good solution for this but one that would work for me would be to upgrade the Integration Services Server from 2012 to 2014, leaving everything else in 2012 (database, ssms, ssas, ssrs).Would this solve the package format problem? Would I then be able to execute my packages in the ssisdb catalog?
View 3 Replies View RelatedNow, I checked and verified that my backup version of SQL Server is the same as the version installed on the computer I'm restoring too.
I have SQL Server on a production machine that I backed up and want to test a full restore on a dev machine to make sure it will work when I need it to.
Now that I've run the restore command on my tape backup and go to restart the SQL server service I receive:
Configuration block version 0 is not a valid version number. SQL Server is exiting. Restore the master database or reinstall.
I'm afraid I don't understand why this is happening. If the builds are the same, then shouldn't restoring the MASTER database have worked normally and I'd be able to restart the service now?
Any thoughts or suggestions?

I started this thread as the last attempt to sort the issue out.
I have an SSIS package that loads data from a .csv file into my database. It works fine on my developer machine. I start it programmatically or from Management Studio or from Visual Studio, and it works. Then I deploy it to the MSDB database on the computer on which it will have its final place. There again I can start it from Management Studio or from Visual Studio (using the source file), and it works. But when I start it programmatically, it just fails telling me:
Package Warnings:
Package Errors:
The version of component "****" (11773) is not compatible with this version of the DataFlow.
Component "component "Derived Column" (13627)" could not be created and returned error code 0x80070005. Make sure that the component is registered correctly.
The component is missing, not registered, not upgradeable, or missing required interfaces. The contact information for this component is "Flat File Source;Microsoft Corporation;Microsoft SqlServer v9; (C) 2005 Microsoft Corporation; All Rights Reserved; http://www.microsoft.com/sql/support;1".
component "Agreement File" (11773) failed validation and returned error code 0xC0048021.
One or more component failed validation.
There were errors during task validation.
Maybe the source of the problem is that this machine is a 64-bit one, while the developer machine is 32-bit one. But why does the package run fine when I start it from Management Studio?
Any help would be appreciated.

Can some one here give me more insight about how to upgrade a SQL Server 2005 Standard Version (32 bits) to a SQL Server 2005 Enterprise Version (32 bits) as default instance on a Windows 2003 enterprise OS (32 bits). I want to know what is the easist way and what is the safest way. May I preserve some settings I have for the STD version, or I have to start from strach again to configure the server? Is there any catches, anything I should have attention to (We are using heavily about CLR and fulltext indexing)?
Thanks a milliom

Hello,
I installed the SQL Server 2k EnterPrise version and developer version on the same version, and the developer version is an instance "Development".
How do I expose both of them to internet? Just open both of them to port 1433? And on the client side, just say IP and IP/Development? Do I need specific set up, will they conflict?
Thanks,
The version of the report server database is either in a format that is not valid, or it cannot be read. The found version is 'C.0.8.54'. the expected version is 'C.0.8.40'. To continue, update the version of the report server database and verify access rights. I'm getting this whenever try to access the report server via SSMS, I have tried to upgrade via the Reporting Service Configuration Manager but get an error message similar to above except it says: The database version (C.o.8.54) does not match your Reporting Services installation. This version of the database cannot be upgraded. You must use a different database. Has anyone seen this before? I can create a new database, but don't want to loose all my reports. Any ideas. Oh, not even sure if the backups exist from before this error, I've spent 2 weeks trying to get access to the server so I could try to upgrade, only to get the above results. Thanks for your help, David
View 5 Replies View RelatedI downloaded the 101 Samples installation (i.e. 101SamplesCS.msi) from Microsoft's website, which contains SQL Server database files.

I'm trying to write a procedure that having created a new database,will then create within that new database all the tables andprocedures that go with it.In doing this I'm hitting the problem that you can't issue a USEcommand within a procedure.So my question is either- how do I get around this?- if I can't, how can I create procedures etc in a *different*(i.e. the newly created) databaseor- is there a better way to do all this (*)I have SQL files that do this currently, but I need to edit in thename of the database each time before execution, so I thought aprocedure would be better. Also I'd like eventually to expose someof this functionality via a web interface.Although I'm a newbie, I feel I'm diving in the deep end. Any goodpointers to all the issues involved in this aspect of databasemanagement would be appreciated.(*) One thought that occurs to me is to have a "template" database,and to then somehow copy all procedures, tables, view etc from that.--HTML-to-text and markup removal with Detaggerhttp://www.jafsoft.com/detagger/

Using SQL 2005, SP2. All of a sudden, whenever I create any stored procedures in the master database, they get created as system stored procedures. Doesn't matter what I name them, and what they do.
For example, even this simple little guy:

PRINT 'BOB'
GO
Gets created as a system stored procedure.
Any ideas what would cause that and/or how to fix it?
