Hi.
I'm new to SQL and trying to solve this question (I have solved many others, but having problems with this particular one) :
there are 3 tables describing voters in america
Ballot_box(ballot_box_num,SettelmentID,Street,HouseNum)
Settelemnt(SettelmentID,Settelment_name)
Voter(ID,voter_name,Adrress,Birth_date,ballot_box_num)
The question is :
Write a SQL query that show the names and codes for all settelments that have less than 100 voters.
I have a performance issue with a Cognos report against SQL Server 2005. The total running time of the report is 1 minute 15, and using SQL Profiler I found out that 1m13 is spent preparing SQL. Execution and generating the report takes up 2 seconds; no problem there. The SQL is the same every time I run the report, yet SQL Server spends 1m13 preparing it every single time! I'm no DBA, but as far as I understand that's not what's supposed to happen; once prepared, the SQL should execute quickly every time.
Is there a way to stop SQL from preparing the statement every time?
(Cognos 8 against SQL Server 2005 through OLEDB. Oh, and this query takes about a second when run in EM.)
We are setting up a test lab environment with 100 machines. We want one master testing db that gets replicated to each to run scripted application tests nightly.
My goal is to minimize the amount of work to move this thing to each of the 100 test machines. 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.
I would like to prepare a string variable for SQL insertion. Like, replacing all the single quotes with the HTML code equivilent and such. Has anyone written alything like this? Is there a tutorial on the web for it? A control maybe?
I want to prepare insert statements for the data of all tables in my database. I want this to create seed data. Just by using those scripts i can insert the data in another db. Please suggest ho wto prepare in easy way.
Now 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?
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. Regards Arif shareef
I have an SSIS project that is deployed to a sql server.
The setup of the project is a parent dtsx package, and many child packages.
The parent executes each of the chid packages.
If I run the parent from BIDS, calling the children that are on the SQL Server, it works fine.
If I execute it from SQL Management Console running on my laptop, connected to the SQL Server, It works.
If I remote into the SQL Server and run it from SQL Agent or SQL Management Console, the job fails with the error:
Error 0xC0202009 while preparing to load the package. SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x%1!8.8X!. for each of the children.
This has quite suddenly stopped working, and I cannot figure out why it will work being executed from my laptop, but not on the server.
This post is for informational purposes only, as I have solved the issue. However, it was such a sneaky issue that I thought I would share.
I was working from home on a working SSIS package. I deployed via dtutil, and then ran it.
It failed immediatly with the error:
"Error 0xC0011008 while preparing to load the package. Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored."
Nothing on the web helped me.
Well, after about 10 hours of working with it I figured it out.
The first package loaded in SSIS is my parent package, which executes other packages stored in SQL Server.
When I first loaded up the package, my VPN was still connecting. Since I was not on the VPN when this package loaded, it could not validate.
Without any indication, my connection to the SQL Server storing the packages was invalid. All I had to do was open it, and click on OK.
So be aware... If the validation cannot take place, bad things can happen ;-)
I have Vista Enterprise 64-bit. I have followed the 3 links in this Answered Link. http://forums.microsoft.com/MSDN/ShowPost.aspx?siteid=1&PostID=2756202
I can turn on the IIS bits under Web Management Tools and Windows Authentication
But when I try to turn on the World Wide Web Services stuff I get "An error has occurred. Not all of the features were successfully changed" and when I click OK it has not turned on any of the fetures under World Wide Web Services.
I have a package which calls another package. It had been working fine for a while. Recently I changed the connection managers' names. Everything in the parent package works fine. Database has been updated correctly. But when it comes to calling the child package it generates :
OnError,CRPRCHMSQCZ,,Execute AMSClientAgentMaintenance,,,3/8/2007 5:49:38 PM,3/8/2007 5:49:38 PM,-1073602332,0x,Error 0x80070002 while preparing to load the package. The system cannot find the file specified. . (there is a period here instead of a file name)
I tested the child package on the server. It works fine. I connected the child package to the Execute Package Task by selecting from the packages on the server. So it is there for sure. Connection manager's name is read from the .dtsConfig. Child package is executed from my development machine but not on the server. I made a small test package just to call this child package, it generates the same error...
I need to restore test DB from production backup but once it is restored I would need all the permissions of sql logins and windows AD account intact in test Db as it was before.
I am having problems executing a child package from a parent package using the Execute Package Task. I am attempting to run the master package through a SQL Server Agent job.
The SQL Server Agent job is owned by sa. The step that runs the parent package is configured to load the package from the SSIS Package Store on the same server that the job is running.
I have the Execute Package Task configured as follows:
Location: SQL Server ExecuteOutOfProcess: True Connecting as a SQL Server login (let's say TestEtl)
I have added the db_dtsoperator database role to both the TestEtl login and the login that SQL Server Agent connects through. I have also configured the child package's reader role to include db_dtsoperator. Per http://msdn2.microsoft.com/en-US/library/ms141053.aspx, this should allow these logins to run the child package.
I have enabled logging of all events in both the parent and child packages. I see the following in the logs when the Execute Package Task executes (omitted portions unrelated to the execution of the child package task):

I am sure that what I am doing is quite common, and I obviously have something misconfigured somewhere - but I'm not sure what my misconfiguration is. Can anyone enlighten me?
I cannot execute a package by using Execute Package task. I supplied sa credentials to connection manager, and it shows the list of Packages on SQL Server but when running the task it says
Error 0xC0202009 while preparing to load the package. An OLE DB error has occurred. Error code: 0x%1!8.8X!.

I recently lost my job and wanted to do some test development to keep my skills up to date. The problem is I don't have access to any data sources. Is there such a thing around? I tried installing microsoft's trial of SQL 2005 but can't get it to run on my laptop and SQL 2000 trial no longer exists. I simply need to create a SQL db/tables etc. Thanks in advance.
Hi! I am currently utilizing the checksum function to generate a hash that I later compare to detect changes in a row. CHECKSUM(field1, field2, field3, field4) Now I'd like to use the HashBytes function instead over the same fields. But the HashBytes function accepts only one data value. What is the most effective and reliable way of getting an MD5 over several fields? Thanks
Hi. I have an application where I allow users to type in their SQL queries. Before I store those queries I have to make sure that they are correct, both syntax-wise and data type-wise. For that I execute the query against the database and trap any errors that may be returned and that's how I judge if the query was OK. In order to keep this test as quick as possible, I tried to add a WHERE clause to it like: WHERE 1=2, so no results are returned. But then I discovered that the addition keeps errors from happening if they are of ata type nature.For instance "select orderid + 'test' from orders where 1=2", run against the Northwind database, returns no errors, while OrderID is numeric and U'm adding a string to it! Next, I tried to return only one row: "select top 1 orderid + 'test' from orders". This time the error is thrown, however the query still takes a looong time when run on a huge table. I don't kknow why that is, but it seems that the engine runs the query for the entire table and then gets the first row! Does anyone have an idea ehat's happening or have a better suggestion on how I can perform my test without killing the database? Thanks.
I have a stored procedure which runs a query, then turns it on its side (so that the rows are column headers).What I need to do now is test if any of the values in a row from this stored procedure are null.Any suggestions on how to get started? Is there some function that will tell me if any value in the row is null?
I'm having a problem with a VB6 program I'm writing that posts data to a SQL server. The problem occurs when the SQL server is unavailable. When this happens it causes the program to hang for at least 30 seconds before releasing. The hang happens at the code that connects to the SQL server, because the server isn't there. I've added code found on this site to test the connectivity prior to making my actual data connection, but this causes the same hang. Is there any way to verify connectivity to an SQL server without actually trying to make the connection? I'm really trying to eliminate the hang that occurs when the server is unavailable.
I have gotten some criticism from coworkers regarding this test and just wanted to see what you guys think. I realize the wording could use improvement and any criticism towards making it easier to understand is much appreciated.FWIW - I had to solve this problem on the job so I feel it is a real-world test that helps me understand how people think and if they try to find alternate solutions.Thanks!~~~~~~~~~~~~~~~~~~~~Given a table that has over 100,000 records…SUBSIDIARY=========PARENT_IDINTCHILD_IDINTULTIMATE_PARENT_IDINTCLEANUP_INDBIT…where each PARENT_ID can have multiple CHILD_ID values, but the PARENT_ID should not equal the CHILD_ID.

Whats the best way to test scalability on a database? I'm working on a new app, and have handed off developing the database to someone with more experience. Some tables will grow to many million records, and I don't want it to bottleneck. I need to have it fully tested before it goes live.
Is it reasonable to ask the person helping me to fill it with 10's of millions of rows to test performance? Is this a decent solution? If so, what would the best way to fill it be? If not, what steps should I take?
