Jan 12, 2008
Hello all ...
I am facing a problem in the evaluation form that I am working on ...
I have 3 textboxes which are
Trainee ID, Trainee Name and Trainee Department
I want the Trainee ID to be saved in the Evauaiton form , The trainee id is a foregin key in the Evaluation table in my SQL table, it is coming from the trainee table where the Trainee ID is primary key and it is incremneting ...
I want the same Trainee Id to be sent to both Trainee and evaluation table , but at the same time , i want whenever a user open the evaualtion form an id will be shown and it will be inccremented ...
Hope that is clear ...

I have a trade data tables (about 10) and I need to retrieve information based on input parameters. Each table has about 3-4 million rows.
The table has columns like Commodity, Unit, Quantity, Value, Month, Country
A typical query I use to select data is "Select top 10 commodity , sum(value), sum(quantity) , column4, column5, column6 from table where month=xx and country=xxxx"
The column4 = (column2)/(total sum of value) and column 5=(column3)/(total sum of quantity). Column6=column5/column4.
It takes about 3-4 minutes for the query to complete and its a lot of time specially since I need to pull this information from a webpage.
I wanted to know if there is an alternate way to pull the data from server ?
I mean can I write a script that creates tables for all the input combinations i.e month x country (12x228) and save them in table (subtable-table) with a naming convention so from the web I can just pull the table with input parameters mapped to name convention and not running any runtime queries on database ??
OR
Can I write a script that creates a html files for each table for all input combinations save them ?
OR
Is there exists any other solution ?

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

Hello,
I am wondering what conversion rules apply, when a string, which contains a number, is saved to a SQL Server 2005 into a column of type decimal.
This is the code I€™m using (C++):
CString cValue = "0.75"
_variant_t vtFieldValue;
vtFieldValue = _variant_t(cValue)
pRecordSet->Fields->Item["MyColumn"]->Value = vtFieldValue;
"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".
The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.
I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.
So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?
Thank you for your help.
Regards,
Volker

Hi Guys,
I am trying to automate a basic task using SQL Server 2005 Express.
Currently I have a query script that I run and then save the results as a CSV file. I need to do this on a daily basis and so I am looking to find out how best to go about this. There are a multitude of third party tools that claim to be able to do this - can anyone recommend this or enlighten me of the best way to set up this automation.
All ideas gratefully received!

Hi,There are 3 tablesTable,TableDetails,TableDaily.With structureTABLE:TableID UserID Money---------- ---------- ----------(int) (int) (money)TABLEDETAILS:TableDetailsID TableID ItemID PaidForItem DayID---------- ---------- ---------- ---------- ----------(int) (int) (int) (money) (int)TABLEDAILY:TableDailyID TableID PaidForItem Money Total Change---------- ---------- ---------- ---------- ---------- ----------(int) (int) (money) (money) (PaidForItem + Money) (money)"Table" holds id for user and his money amount, which changes during time. "TableDetails" holds data about items user bought, amount paid for them and dayid which relates to one particular day."TableDaily" holds history. I do not know how to update this table.I created job whish runs stored procedure. This procedure sums "PaidForItem" using group by TableID and WHERE DAYID = '11'.Problem is with Change column. This column sould hold difference between today's Total and previous one etc.Current procedure looks like this:INSERT INTO TableDaily (TableID, PaidForItem, Money, DayID)SELECT TableDetails.TableID, SUM(PaidForItem) AS PaidForItem, Table.Money, (SELECT DayID FROM Days WHERE (Aktive = 1)) AS DayIDFROM TableDetails INNER JOIN Table ON TableDetails.TableID = Table.TableID GROUP BY TableDetails.TableID, Table.Money

Hi
I’m making a very primitive shopping cart. I’ve created a table containing a list of products and using an SQLdataSource with a GridView I’ve got the products displayed – simple.
What I now need is to add a button with an Insert command, but the SQL needs to add a row of data to a different table – tblShoppingBasket. I’ve tried adding in the insert command and changing the SQL but it doesn’t add a new record, although is also doesn’t through and error.
The second part of the problem is need to pass the productID from the row they selected (pressed the button that triggered the insert command) and add this to the shoppingBasket table via the insert SQL.
I’d really be grateful for any help (code below).
ThanksRichard
<asp:SqlDataSource ID="SqlDataSource_GenralProducts" runat="server" ConnectionString="<%$ ConnectionStrings:AquilaConnectionString %>"
SelectCommand="SELECT * FROM [tblProducts] WHERE ([productAgeGroup] = @productAgeGroup)"
InsertCommand="INSERT INTO [tblShoppingBasket] ([userID], [productID]) VALUES (@userID, @productID)">
<SelectParameters>
<asp:Parameter DefaultValue="3" Name="productAgeGroup" Type="Int32" />

Hi,
Here is a structure of my table
create table events( event_id integer primary key identity(1,1), event_name varchar(200), event_date datetime,)
Note: The event_id is a automacally and we don't need to insert record in this field.
for example
i have inserted 10 records in a table
then i deleted all records manually from sql server
but when again I save the record the event_id field shows started from 11 even the table was empty,
although it should be start from 1?

Hi,
I have a page for saving a "home" data. As the page unloads I will
redirect the user to the page on which he can add the photos to this
"home".
Well I structured my photo adding page with first requesting the "homeID" which is an auto Integer (PK).
Because it's renaming the uploaded photos with the homeID and _01, _02...
Because of that i need to send the user to the photo adding page with "response.redirect......aspx?homeID=.....
homeID= ???
But I don't know how to get the homeID value, that the SQL Server automaticly selects for the data. As it is just saving it...
Thanks a lot.

Hello,
Yesterday I was looking to the processor usage in the Task Manager of Windows NT when a script of mine was running. The script was an InfoPump Script; which is a tool from the DecisionBase suite from CA (was previously owned by Platinum). This script contains SQL statements that select data from several tables and stores the result into another table. The SQL code used for this looks fine to me.
The query was running on a Compaq Proliant 5500 with 4 500 Mhz Xeon processors, 1 GB RAM, NT Server 4, SP 5, RAID 5. The SQL Server is configured to use all resources and SQL has normal priority on NT.
When the select part was running al four processors were used for about 75% and when the store happens only 1 processor is used for 100%.
Why is the store not spread over all four processors? It only uses one processor and it seems to be a bottleneck.

I have been trying to place a binary byte array into the sql server mobile 2005 database and continually get an error "The Identifier cannot be an empty string." when attempting to save this sql to the database:
"INSERT INTO KHZ_Company_Permissions ( PermissionID, CompanyID, StatusID, PluginTypeName, PermissionLevel, ChangeStamp, RecordState ) VALUES (1, 1, 1, 'Plugins.Approval.ApprovalList', 2, System.Byte[], 0)"
the byte array ChangeStamp is a timestamp datatype in the Sql Server Database and is pulled into a custom business object as the .net datatype Byte()
in the debugger, the byte array looks like it should as a timestamp comprised of 8 bytes with the values: 0,0,0,0,0,0,63,181 . but when i attempt to execute the sql statement, i get the sqlceexception "The Identifier cannot be an empty string." if i change the byte to a string and save it as an nvarchar, the value is preserved and i can then pass it back to compare it to the timestamp when synching up to the Sql Server Database later, but i would prefer to maintain the type as a binary datatype, and avoid the string conversion...
When i am creating the sqlstring (which i then run using a sqlcommand/nonquery) i add the binary data to the sqlstring by referencing the .tostring character ... do you think this may be what is causing the error, and if so, is the only way to insert binary data to a sql ce db by using sqlcecommand parameters?
i have found no information to assist with this error, any ideas are much appreciated

Hi! I am developing a CF 2.0 application for WM 6.0. In the application I'm doing a replication between a Sql Server 2005 database and a Sql Server 2005 Compact Edition database. When I'm trying to syncronize the databases for the first time, e.g., creating a new database with AddSubscription(AddOption.CreateDatabase)I cannot do a save afterwards the synchronization procedure. The synchronization works just fine and I get the right data to my device and so, but when I try to a save, the database hangs doing the commit().
If I'm on the otherhand restarts the application and then do a ReinitializeSubscription(true), e.g., doesn't not create a new database with AddSubscription(AddOption.CreateDatabase), and calls Synchronize(), everything works just fine. Anyone who has an explanation of this? (I do a Dispose() each time).

I am looking for some advice regarding saving custom component data when saving packages.
For custom "properties", this is not an issue, as saving the package will save these properties. Howver, I also have information for each column (besides the properties that columns provides, like Name and DataType) that I need to save if a package were to be saved, and right now it does not save because I am using my own objects to store the data.
I am wondering as to how I can save this information. I have looked up on serialization, but I would like to know if there is another way besides serialization to save this inforamtion as I'd rather not save this to a seperate file.
Thanks

I am working on reformating, cleaning, adding derived elements, etc... on data with no data validity checks on the front-end, source data. Its an incremental process where each month I add new data to the prior months' history. Sometimes the new monthly source data "surprises" me -- different values, different data definitons, etc. than expected.
I deal with these surprises by accumulating the fields/values that are unexpected after converting them to varchar with some explanatory language into a table [program_newdataprobs]
If there are any records in [program_newdataproblem] I rollback the transactions so the prior months' history remains unaltered. The problem is I then "lose" the contents of [program_newdataproblem] which I would like to hand to the source data people to troubleshoot.
I have tried the following:
Begin Transaction tran1
.... code that reformats data here
if (select count(*) from program_newdataproblem)>0
BEGIN
Begin Transaction tran2
select * into #t1 from program_newdataproblem
Commit Transaction tran2
Rollback Transaction tran1
insert into program_newdataproblem
Select * from #t1
END
This bombs because because #t1 no longer exits
Any way I can "keep" the data from program_newdataproblem when I Rollback the other transactions? (without having to store the history in separate tables that I can then access if new data errors occur)
Thanks,

The following T-SQL code is run in a vb.net (2003) module.
I am acquiring data from an OPC server into an array of data type object. It is necessary to declare the array as an object for the OPC server to return data. The OPC returns the data in 15 mS.
I now need to save this data to a table in SQL 2005 running on a 2003 server.
The table for saving the data has already been created and saving the data is actually an 'update ... set ... where' statement.
The statement is
For i as short = 1 to itemCount
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = " & itemValue(i) & " where TagName =' " & tagName(i)
sql_command.executeNonQuery
Next
The TagValue field datatype is decimal(18,6)
The itemValue(i) datatype is object / variant. The itemValue array contains 95% values of type Single and the rest are Integers.
The TagName datatype is varchar(50)
The tagName(i) datatype is string
When I run the loop (255 iterations) with the above query it takes 1500 mS.
If I force a conversion by changing the query to
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = Convert(decimal, " & itemValue(i) & ") where TagName =' " & tagName(i)
it takes 900 mS to execute for 255 iterations.
I tried one more variation
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = Convert(decimal(18,6), " & itemValue(i) & ") where TagName =' " & tagName(i)
which takes 1200 mS to execute for 255 iterations.
If I use the following code
dim tempValue as decimal = 123456789012.123456D
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = " & tempValue & " where TagName =' " & tagName(i)
it excutes in under 100 mS for 255 iterations.
There seems to be a problem during implicit / explicit conversion of type object/variant to decimal.
I need to save the data received from the OPC (255 tags) in under 150 mS.
Could somebody help?

I am running SQL Server 2000 SP3 and I am trying to save a DTS package into Meta Data Services and I am receiving the following "Package Error"
Error Source: Microsoft Data Transformation Services (DTS) Package
Error Description: General Error -2147217355 (80041035).
I have searched for this error and I cannot find anything related to it. Also, I saw some of the comments about right clicking "Data Transformation Services" and checking the box for allow save to Meta Data Services, however, I do not see that checkbox to allow for this. Has anyone else had this problem and resolved it? I'm beginning to get very frustrated with it.

Last weekend many of our severs had a failed job "collection_set_3_upload". The error that occured is: "Violation of PRIMARY KEY constraint 'PK_ active_ sessions_ and_requests'. Cannot insert duplicate key in object 'snapshots.active_sessions_and_requests'. The duplicate key value is (2824333, 2015-10-25 02:54:49.7630000 +02:00, 1)."Last weekend we happened to go from summer time to winter time. i.e. the clock passed 02:00 - 3:00 two times during this night.
I.e. there is a bug in the Data Collector component that collects data for the Management Data Warehouse: it uses local time instead of UTC. I've created a Connect item to report it to Microsoft.URL...how do you get your process running again? the job will no longer run because it will every 5 minutes keep on trying to upload the conflicting data for the 2nd 2:00 - 3:00 period. I've only found one solution: get rid of all data collected but not yet uploaded.
You do this by stopping the Collection set (in SSMS go to Object Explorer -> <the server you want to fix> -> Management -> Data Collection -> System Data Collection Sets. Right click "Query Statistics" and select "Stop Data Collection Set").Then you delete the cached results from the sql server machine's harddisk. These cached results are in files located in a Temp folder on the sql machine itself, inside the AppData folder for the service account SQL Server Agent is running under. Usually it will be something like: c:Users<sql agent service account>AppDataLocalTemp.
Inside this folder delete all files that have 'QueryActivity' in their name. You'll loose all data collected since the start of wintertime, but at least your data collection process will work again.After this you can start the Collection set again by right clicking it and select "Start Data Collection Set". Every 5 minutes the data will be summarised and uploaded into your management data warehouse.
