DB Engine :: Replicate A Master Test Database To 100 Test Environments?
Oct 12, 2015We are setting up a test lab environment with 100 machines. Â We want one master testing db that gets replicated to each to run scripted application tests nightly. Â
My goal is to minimize the amount of work to move this thing to each of the 100 test machines. Â I am wondering if we need to even have the sql local and invest in a monster db server with 100 copies of the db we restore and each test machine point to their own db on that server, or if I should use db mirroring or something to get the master test db to each of those machines instead.
Unit Testing For SSIS - To Test Or Not To Test?
Oct 17, 2006Now that we have a good programming model in SSIS - the question is whether to write automated unit tests for your packages, and would it generally be a good idea for packages?
Also - if yes to write tests - then where to find more informations regarding How to accomplish that?
How To Test SSis Package And What Are The Things I Need To Test It ?
Nov 27, 2007
hi every one,
i need to test SSIS pacakge which will import data from different database where record count is around 5 millions.
iam planning to test it through c# code as well as manually also.
SSIS source : consist of 7 tables
SSIS destination :consist of 7 tables
Using c# code iam trying to run ssis package through batch file.
i am putting expected rowcount, column count in an excel file and comparing same with destination tables by writing query implementing ADO.Net concept.
am i going right way ,can any one suggest best and productive way to test the ssis package .
what are the other things i need to test it.
do any one can add test cases to it.
S.No
Test Case
1
Verify all the tables have been imported.
2
Verify all the rows in each table have been imported.
3
Verify all the columns specified in source query for each table have been imported
4
Verify all the data has been received without any truncation for each column.
5
Verify the schema at source and destination
6
Verify the time taken /speed for data transfer
7
Fields truncated due to difference in length of the field at destination.

Jul 20, 2005I see a lot of example, but where do these example procedures go. Likedeclare (whatever)?below is an example i read. Where do you put this to make it execute, is itthe view screen or the stored procedure screen?I'm using MSDE now to learn, and I can't get nothing working except simpleselect query statements.In the northwind example (northwindcs), how would I do a parameter querylike this:Have a dialog box ask user to enter customerid to bring up. (in a query nownot a form)Also, how would you check if a certain customerid exist? Example, CHOPS isone customerid. If I wanted to use a query to check if it exist, and returnno records, but just do an action (like add a record) if it didn't exist,how?[color=blue]> CPU SQL> (ms)> -- Convert to varchar (implicitly) and compare right two digits> -- (original version -- no I didn't write it)> 4546 select sum(case right(srp,2)> when '99' then 1 when '49' then 1 else 0 end)> from sf>> -- Use LIKE for a single comparison instead of two, much faster> -- Note that the big speedup indicates that> -- CASE expr WHEN y then a WHEN z then b .> -- recalculates expr for each WHEN clause> 2023 select sum(case when srp like '%[49]9' then 1 else 0 end)> from sf[/color]I tried some variations of this, and indeed it seems that there is a costwhen the expression appears with several WITH clauses. I tried a variationof this, where I supplemented the test table with a char(2) column, so Icould factor out that the WITH clauses themselves were not the culprits.CREATE TABLE realthing (realta real NOT NULL,lasttwo char(2) NOT NULL)goINSERT realthing (realta, lasttwo)SELECT r, right(r, 2)FROM (SELECT r = convert(real, checksum(newid()))FROM Northwind..Orders aCROSS JOIN Northwind..Orders b) AS fgoDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE right(realta, 2)WHEN '99' THEN 1WHEN '49' THEN 1WHEN '39' THEN 1ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 20766 ms.goDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE WHEN right(realta, 2) LIKE '[349]9' THEN 1 ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 8406 ms.goDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE lasttwoWHEN '99' THEN 1WHEN '49' THEN 1WHEN '39' THEN 1ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 920 ms.goDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE WHEN lasttwo LIKE '[349]9' THEN 1 ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 1466 ms.Thus, when using the char(2) column LIKE is slower despite that thereis only one WHEN condition. So indeed it seems that right(realta, 2)is computed thrice in the first test.Another funny thing is the actual results from the queries - they aredifferent. When I ran:select count(*) from realthing where lasttwo <> right(realta, 2)The result was about half of the size of realthing! I can't see thatthis difference affects the results though.Now, your article had a lot more tests, but I have to confess thatyou lost me quite early, because you never discussed what is theactual problem. Since you are working with floating-poiont numbersthere is a great risk that different methods not only has differentexecution times, but also gives different results.--Erland Sommarskog, SQL Server MVP, Join Bytes!Books Online for SQL Server SP3 athttp://www.microsoft.com/sql/techin.../2000/books.asp

Jul 6, 2006Hi!
I was just wondering if there are any examples on how to work with the Script Editor, and more specifically how to use the DirectRow method? I've seen some examples that say that the editor automatically creates the methods DirectRowTo<output buffer>, but it doesn't say how that is done. If I just specify Row.DirectRow(output buffer #), it says that the method is protected.
Any help or just pointing me in the right direction would be greatly appreciated!

SSIS Programming Examples
Mar 28, 2006I have been creating SSIS packages programmatically and have run into somewhat of a dead end. I have found the examples provided with the SQL 2005 install very helpful, but they only cover setting up three tasks: Sort task, OleDB Source and a Flat File Destination.
Does anyone have any examples or knows of examples of using the Merge Join task and the Conditional Split task?
I'm doing it all programmatically and so far I'm having trouble finding much in the way of documentation or examples.
Any help would be great!
Thanks,

ADS Wizard, Tutorials And Examples - Please Help.
Oct 26, 2006Hi,
I'm new to SQL Server Technology and am trying to learn how to create a Mobile Device application and to sync it with a desktop application that uses Access. I have found a lot of information but some of it doesn't seem to make sense.
I found this blog: http://blogs.msdn.com/sqlservereverywhere/archive/2006/08/29/729730.aspx which is the announcement of Access Database Synchronizer (ADS) CTP. I downloaded it and installed it with all the prerequisites. This is the part i can't understand:
"The CTP setup installs the desktop component required for synchronizing Microsoft Access database with SQL Server Everywhere Edition database on the device."
I cannot seem to find the desktop component to try out! The Readme shows you how to pull and push data but i can't see where the desktop data sync wizard is located. Should there be something installed on my desktop that i can see?
Also, there doesn't seem to be much help or examples around on this component as yet. Can anyone point me in the right direction for examples, help, or tutorials on this.
This paragraph also confuses me:
"Note: As of today only SQL Server Mobile Edition is available for devices. SQL Server Everywhere Edition whould be available for devices at time of SQL Server Everywhere Edition RTW whihc is planned for November 2006".
Does this mean SQL Everywhere won't work on mobile devices until November?
Sorry for all the questions but i'm still trying to learn this stuff so i can write my application for Windows CE. Thanks in advance.

New - Learning By Code Examples - Need Guidance
Feb 25, 2005Hi
I'm learning by going through the tutorials and such and modifying the code to try and learn how to do more and different things.
I have a MSDE Database, and I'm building a query from the WebMatrix Code Builder.
I can get a Select and Where to work on a "Category" colum as String; to return from a text box control (where I enter the name) and on button click.
What I would like to learn how to do and am having trouble is do a select Where "Category" (string) and "Status"(Int) are the same.
I have two Seperate Textboxes after i make the Where / And Query, but I'm not sure i have the button click code right.
I have included the code below - Sorry if this is so basic ;-) - The Sub_Button1 Click is at the end.
Function ShowRecords(ByVal category As String, ByVal status As Integer) As System.Data.DataSet
Dim connectionString As String = "server='(local)'; trusted_connection=true; database='SalesContacts'"
Dim dbConnection As System.Data.IDbConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "SELECT [Contact].* FROM [Contact] WHERE (([Contact].[Category] = @Category) AND ("& _
"[Contact].[Status] = @Status))"
Dim dbCommand As System.Data.IDbCommand = New System.Data.SqlClient.SqlCommand
dbCommand.CommandText = queryString
dbCommand.Connection = dbConnection
Dim dbParam_category As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_category.ParameterName = "@Category"
dbParam_category.Value = category
dbParam_category.DbType = System.Data.DbType.String
dbCommand.Parameters.Add(dbParam_category)
Dim dbParam_status As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_status.ParameterName = "@Status"
dbParam_status.Value = status
dbParam_status.DbType = System.Data.DbType.Int32
dbCommand.Parameters.Add(dbParam_status)
Dim dataAdapter As System.Data.IDbDataAdapter = New System.Data.SqlClient.SqlDataAdapter
dataAdapter.SelectCommand = dbCommand
Dim dataSet As System.Data.DataSet = New System.Data.DataSet
dataAdapter.Fill(dataSet)
Return dataSet
End Function
Sub Button1_Click(sender As Object, e As EventArgs)
DataGrid1.DataSource = ShowRecords(CStr(TextBox1.Text)&(CInt(TextBox2.Text)))
DataGrid1.DataBind()
End Sub
Any Good Audit Trail Examples?
Jun 17, 2002Hi Guys!
What's the best way to keep an audit trail of every insert, update, and delete of a certain table? Any example code out there? I'm thinking in terms of a trigger for each event, for instance, the update trigger would insert a new record into the audit table with a field for each column in the deleted table and a field for each column in the inserted table.
Thanx

Any *simple* External Activation Examples Available?
Feb 13, 2007BOL only seems to say that you can do it w/o really showing how, and the ExternalActivator sample at gotdotnet.com contains so much functionality I'm not sure what's required just for the external activation. Are there any docs or samples out there that focus on how to do it w/o obscuring the matter with a bunch of other functionality? (I prefer docs to project samples, b/c the samples tend to have hacks like hardcoded paths and connection strings so that they rarely work correctly right out of the box.)

Database Examples For SQL Server 2005
Nov 8, 2007Hi,
I have installed SQLServer 2005 along with Visual Studio 2005 Professional. I am trying to study some database examples (CreateDB for example) but I always get the mesage that I need the Northwind database installed. I cannot find it anymore in the examples provided for SQL Server 2005. In the links provided after the error is displayed, I find that I should install SQL Server Express. I do not really want that because of some possible conflicts with the other 2005 version of SQL Server.
Is there a place I can download the Northwind database from? Will it work with SQL Server 2005?
Thank you.

Examples Of OleDb With SQL Server Compact Edition
Jul 31, 2007Hello,
My C# .NET application is currently using the System.Data.OleDb namespace to access SQL Server 2000 and SQL Server Express databases. I would like to begin using SQL Server Compact Edition to access a local database that has the same structure as the others. I'd like to use the same code regardless of the data source, so I would prefer to use System.Data.OleDb instead System.Data.SqlServerCe.
Where can I find examples of the use of System.Data.OleDb with SQL Server Compact Edition? Some of the specific questions I have are:
1.) How do I build the connection string for the OleDbConnection object?
2.) What are the limitations, if any, of using OleDb instead of SqlServerCe?
I will appreciate any help you can provide.
Thank you,
