Performing A Very Peculiar Task
Jun 1, 2007
Hello All,
I am tackling with unique request. I have to download the ".zip" files from the https and uncompress them. Now, the fetch process works fine when I am downloading the files. Using .net and .IO namespaces from system library.
Similarly after downloading I have to uncompress the files as these files are treated by compressed file folders by windows xp. I know it can be achieved by using the IO.compression class form system namespace.
But the only trouble here is IO.compression supports ".gz" and "Gzipstream.Uncompress" and I wonder how I would be able to get the ".zip" and "Zipstream.uncompress" done.
Thanks a million in all your help and advice. Also I appreciate for your time.
Regards
Sandesh

Hi,
I am having an issue when performing an FTP atsk to a remote site ( as opposed to internaly on a LAN )
I get the error "[Connection manager "FTP Connection Manager"] Error: An error occurred in the requested FTP operation. Detailed error description: 200 Type set to IMAGE. 200 command successful 550 permission denied . "
I can manually FTP to this site from my machine, using either a CMD window or Windows explorer. I can create folders, deposit files, delete files etc so I seem to have full control. This task works when testing on our local FTP server on the LAN. The "Test" connection works when configuring the connection to the remote site. It is just at runtime that the task fails.
Can anybody come up with any ideas why this may be ?
Thanks.

Hi, I'm using the lookup task to perform updates on some records and it seems to be working correctly but isn't making all updates. I have a case where there are 543 rows in my source connection, there are 436 of them that do not match the date column of the 543 in my destination table. It only updated 224 of them when it should have updated all 436? Does anyone know why it would only update this many instead of all? I also had another that only updated 18 out of 19 instead of all 19.
thanks,

I have an Access 2.0 database that holds call data on a mapped drive. I am running MS SQL Server 2000. I can open it and view the records inside. I can even run the query below and get results, if I removed the CallDate and CallTime parameters.
SELECT CallDate, CallTime, Mid(CallRecordData, 68, 3) AS Extension, 'I' AS Direction, Mid(CallRecordData, 34, 11) AS Called,
Val(Mid(CallRecordData, 18, 2)) + Val(Mid(CallRecordData, 21, 2))/ 60 AS Minutes, Val(Mid(CallRecordData, 21, 2)) AS Seconds
FROM CallRecords
WHERE (CallDate = ?) AND (CallTime >= ?) AND (CallTime < ?) AND (Mid(CallRecordData, 30, 1) <> '9')
When I preview in the Transform Data Task, I get:
Package Error
Error Source: Microsoft JET Database Engine
Error Description: No value given for one or more required parameters.
When I look at the parameters, they are listed. I check their values, and they have the appropriate values (DateCalled, String, 07/14/2005) (StartTime, String, 06:30) (EndTime, String, 07:00)
When I run it in the build query or in Access with a linked table to the source, I can enter the values when asked for them and it works.
Thanks for any help you can provide.

Hi all,
We have a issue with the performance in SQL server database.
Scenario & Issue:
We have delivered a .net application to our client. This application is installed in newly built windows 2003 server.
The client is facing performance issues with the application. When compared with the performance in the development server , the performance of the production server is very poor.
Even when we execute the stored procedures in the backend, the performance is poor in the production server.
Example: A stored procedure that takes 16 seconds in the development server takes 17 minutes for the same parameters. The time remains the same even for HOT execution.
System Info:
Database Version - SQL Server 2005
Database Size - 120 plus GB
OS Platform - Windows 2003
Database Load - 50 users
CPUs - 4
RAM - 8 GB
The OS is Clustered ( failover clustering ).
Points to Note:
1.There is a huge table with 250 million rows ( this table itself takes upto 60 GB )
2.The huge table is partitioned ( SQL server 2005 table partitioning ) and placed in 20 different filegroups (.mdfs).
3.The .mdf's are placed in a SAN and .ldf is in local HD
4.Dynamic queries are used at few instances for performance benefits.
Questions:
1. Any thoughts on why this kind of performance issue arises ?
2. The client DBA wants us to clear the data and stored procedure cache before executing the stored procedure and test the performance.
Will this be would be the case in production scenario ?
3. Will the performance change based on the input parameters ?
4. The client DBA also have stated that a report server that pings the production database server is the cause for frequent clearing of the SQL Server cache.
When does the SQL Server database actually clears the cache memory? Is there any way to control it?
Any help would be highly appreciated.
Thanks & Regards,
Hariarul

Hi all,
When I execute a SELECT query on a table with around 25 million records, I get
performance difference based on the passed parameter value .
The below queries returns the output in 1 second.
SELECT TOP 10000 * FROM TestTable WHERE Column = 1
SELECT TOP 10000 * FROM TestTable WHERE Column = 2
SELECT TOP 10000 * FROM TestTable WHERE Column = 3
The below query alone takes 18 seconds to return the output.
SELECT TOP 10000 * FROM TestTable WHERE Column = 4
(FYI: The count of records for the column value 4 is lesser than the other column values)
Could anyone please let me know why this happens and how to resolve this ?
Thanks in advance,
DBLearner

SQL Express installation is bombing out with the "A beta version of the .NET Framework 2.0 or SQL Server was detected on the computer...".
From the log file:
Running: PerformSCCAction2 at: 2007/6/26 8:17:27
Loaded DLL:C:WINsystem32msi.dll Version:3.1.4000.2435
Product "{7131646D-CD3C-40F4-97B9-CD9E4E6262EF}" versioned 2.0 is not compatible with current builds of SQL Server.Expected at least version: 2.0.50727.42
The Product Name is ".NET Framework"
Now what is peculiar to me is that
1) this machine should have never had the beta software on it;
2) I have seen people with similar issues except their versioned info always said "versioned 2.0.50727" and the product guid is different, this one only says "2.0"; and
3) I thought that product guid was for the RTM 2.0.50727.42 release!
What is going on here and where is it getting this version information?

Hello,I have this peculiar problem concerning MS SQL Server.My company works with an mailing application (ASP) which uses SQLServer as it's repository. What I want to do is send data directlyfrom my own application to this SQL Server in order to feed themailing application.To test if this was possible I linked the tables from SQL Server in MSAccess and entered the data. This worked fine and the data was pickedup correctly by the mailing application.The problem occurs when I send the data from my application (Javaapplication with JDBC connection). The data is in this case no longerpicked up by the application. The strange thing is that the data whichis entered through Access and the data from the Application lookidentical in de database view. The problem also occurs when the datais send with the tool winSQL and when I view the data in here it stilllooks identical.Even more strange is when I select the record which is not working inAccess and copy it into a new record (only changing the key) itsuddenly works!Has anyone have an idea how this can be?Thanks in advance,Sander Janssen.

we're trying to get a better understanding of how RS behaves when parameters are being set. We see quirky behavior that is a little difficult to describe. Right now we assume that if the revolving green circle (with the phrase "Report is being generated" beneath it) doesnt appear, the report really wasnt rendered properly, even if the report region changes.
One peculiarity that seems pretty consistent is on reports we've prototyped with "from" and "to" date parameters. It seems that when we set one date (doesnt matter which is 1st) things progress normally, ie no "report clearing event" occurs as a result of setting cursor focus in the calendar control and changing its value. The report region doesnt change from what showed previously. But trying to set focus on 2nd (doesnt matter if its "from" date or "to" date, just that its the 2nd date being set) always seems to trigger some kind of event that 1) doesnt allow focus to be on that text box, 2) blanks out the report region including headings. Only after this "event" occurs, can we set focus on the 2nd date, change the value and click the "view report" button for rerendering.
We see similar types of behavior with other types of parameters that include multi value dropdowns and booleans. The toughest part of this is trying to explain it to our users. On some parameters, the event always occurs every time they are changed. On other parameters, it appears that the event only occurs if another parameter was changed beforehand.
I believe we've even seen headings with no data rendered, thinking temporarily that no rows were returned, just to find out that by clicking the "view report" button there really was data to be reported based on current filters. Unfortunately I cant reproduce this scenario when I want to.

Rather than the real code, here's a sample we came up with.
Here's the C# Code:
public class sptest : System.Web.UI.Page
{
protected System.Web.UI.WebControls.Label Label1;
private DataSet dtsData;
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
string strSP = "sp_testOutput";
SqlParameter[] Params = new SqlParameter[2];
Params[0] = new SqlParameter("@Input", "Pudding");
Params[1] = new SqlParameter("@Error_Text", "");
Params[1].Direction = ParameterDirection.Output;
try
{
this.dtsData = SqlHelper.ExecuteDataset(ConfigurationSettings.AppSettings["SIM_DSN"], CommandType.StoredProcedure, strSP, Params);
Label1.Text = Params[0].Value.ToString() + "--Returned Val is" + Params[1].Value.ToString();
}
//catch (System.Data.SqlClient.SqlException ex)
catch (Exception ex)
{
Label1.Text = ex.ToString();
}
}
Here is the stored procedure:
CREATE PROCEDURE [user1122500].[sp_testOutput](@Input nvarchar(76),@Error_Text nvarchar(10) OUTPUT)AS
SET @Error_Text = 'Test'GO
When I run this, it prints up the input variable, but not the output variable.

OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
Try
ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.
part number leadtime
x 5
y 9
....
Does anyone have any idea what I might be doing wrong?
thanks
John

I have two tables that I have to compare:
Table:PR
WBS1 WBS2 WBS3
123-456 1000 01
123-456 1000 02
123-456 2000 02
567-890 2000 01
567-890 2000 02
Table:PR_Template
WBS2 WBS3
1000 00
1000 01
1000 02
2000 00
2000 01
2000 02
After Insert I should have:
wbs1 wbs2 wbs3
123-456 1000 00
123-456 1000 01
123-456 1000 02
123-456 2000 00
123-456 2000 01

567-890 1000 01
567-890 1000 02
567-890 2000 00
567-890 2000 01
567-890 2000 02
Basically, I need to insert the wbs2 and wbs3 where it does not exist in each wbs1.
What I have now will find the values that need to be inserted for a particular project but I don't know how to go through each project and perform the insert:
Select * from PR_template Where Not Exists
(Select Wbs1, Wbs2, Wbs3 from PR where PR.WBS2 = PR_Template.WBS2
And PR.WBS3 = PR_Template.Wbs3 and pr.wbs1 = '123-456')
Order by wbs2, wbs3 asc
Thank You

Hi. I'm trying to find out which "cases" have a new items added to our database. I have provided a sample layout.
ID ParentID Name CreateDate
358 2 SMITH, JOHN 3/3/2008 11:15:23 am
359 358 Invoice 3/5/2008 4:13:52 pm
360 358 Shipping 3/5/2008 5:11:09 pm
361 358 Receiving 3/6/2008 4:22:01 am
The main ID for this is 358. The invoice, shipping, and receiving items are child items. I would like to run a query that can report which cases have newly added items. This is hierarchical I guess and I'm quite lost. I hope this makes sense. Thanks for any help!

Hello,
I want to write a query that joins data in a different table based on a column value. The table is for a "Playlist" and holds play list items. The items can be video, audio, images, etc. The playlist table looks like this:
Table_Playlist
-----------------
ID (int)
MediaType (char)
MediaId (int)
Table_Audio
-----------------
MediaId (int)
Table_Video
--------------
MediaId (int)
If the Table_Playlist.[MediaType] column value = "Audio" then I want to join to the Table_Audio table. If the value = "Video" then I need the video table.
Hope that makes sense. Thanks

Hi,
I was wondering if anyone knows of any way, including third party tools, to replicate a design change on a table across many different databases. I have written an ASP script that allows me to copy multiple tables to multiple databases in one go but I need something that will allow me to replicate the design of a table by comparing source and destination tables. So far I have scripted most of it but I have no idea on which system table to get the identity information and it seems there must be an easier way!
Any help would be appreciated,

I have listed below a sql statement generated by a MS Access query. The Access is the frontend, using a SQL Server 2005 View as the backend. I have already corrected the obvious differences between Access and SQL Server syntax, such as replacing UCase$ with UPPER,
replacing '_' with '.' between the db owner and view name, replacing IIF with IF, and replacing "D" with 'D' and "E" with 'E', but it still generates syntax errors (of course, with no explanation). As you can see, it is SUMing a field based on whether the value is 'D' or 'E', then using those calculated values to calculate a percentage. Can anyone out there let me know what I'm doing wrong?
SELECT dbo_vwDisplayUserList.DEPT_DESC, Sum(IIf(UCase$([Essential_Code])="D",1,0)) AS Department_Essential, Sum(IIf(UCase$([Essential_Code])="E",1,0)) AS EOC_Essential, Count(dbo_vwDisplayUserList.UserID) AS Total_Employees, Int([Department_Essential]/[Total_Employees]*100) AS [%Department_Essential], 100-Int([Department_Essential]/[Total_Employees]*100) AS [%EOC_Essential]
FROM dbo_vwDisplayUserList
GROUP BY dbo_vwDisplayUserList.DEPT_DESC

Hi,I am trying to concoct a query that will join rows on the basis of awhitespace insensitive comparison. For instance if one row has the value'a<space>b' and another has the value 'a<space><space>b' I want them to beconsidered equal (but not the same as 'ab')I am happy to do some T-SQL if that helps. Also I have a full-text index onthe column in question, but note that I am comparing rows against eachother, not to a fixed string.This is for a one-off job, so if there is no obvious way to do it on thedatabase, I will just bcp out the data and knock up some perl or somethingto do it. All other things being equal I would rather do it on the databasethough.Many thanksAndy

Hello.
I have a car table, whose rows contain cars and their respective weight:
Ex: (1, 1000), (2,1100), (3, 900) etx.
I also have a car class table with the classes cars can fall into, based on a lower bound and an upper bound in which the car's weight must fit.
Ex: (Class1, 0, 999), (Class2, 1000, 1499), (Class3, 1500, 1999), etc.
I need to match each car to it's respective class. I've already search the database for post on this subject, but unfortunatelly my goal is yet to be reached. Can someone help?
Thanks in advance,
