Data Fetching... The Right Way.
Oct 12, 2007
Hi,
I'm currently developing an application using C# and SQL Server Express, in which one of the functionalities is to allow the user to browse through the existing products, wether by browsing one by one (next, previous, first, last) or performing a search (by product name, id, etc.). I'm currently using the default DataSource and TableAdapter aproach, but I found out that when I execute the TableAdapter.Fill() method, all the data in the table is fetched... what with 10,000 records it takes a bit to perform, specially on slower connections.
So my doubt is, what would be the best aproach to solve this problem? I'm considering loading first position, and then when the user presses the next button I'd fetch second position, etc, this using ROW_NUMBER(). I could even cache every other 10 records or something like that. Since it is possible to know any records row number (as long as the records are ordered) it would even work when the user performs a search and goes directly into row number 5000 for instance.
Would this aproach be a good practice, because that's all I want, to do things the right way? Thank you for your time
EDIT: I've noticed that when creating a SqlDataReader there is the option to provide a CommandBehavior, but I'm not quite undestanding how this could be used, would some tweaking in this area do the job?

hi,
I would like to know that, I have three instances of the same database at three different servers and I am trying to fetch the data from the select query. "select * from table_name"
I would like to know, whether the order of rows fetched by this query will be different on different servers of sql server or the same order of rows will be fetched.
For me the output is coming different on each server database with he same query . Pls let me know, is there any default order by or it takes it randomly.
Thanks

Hi,
I am getting an error while fetching data from IBM DB2:
I am using an OLE DB Connection provider - "IBM DB2 UDB for iSeries IBMDA400 OLE DB Provider".
I am also setting the "Force Translate" value in "Data Link Properties" of the Connection to "37" because I am getting some BYTE_STREAM data which I need to translate.
I am using the OLE DB Source to extract data using a SQL Query. I can see the data correctly when I do a "Preview".
However, when I execute the task, I get the following error.
It will be great if someone can help me with this.
Error: 0xC0202009 at Customer Telephone, CUSTOMER_TELEPHONE Source [238]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E00.

Hello All,
I have to fetch data in an ssis package from a set of web services. what is the best way of doing this?
The web services are session based, this means that multiple calls are needed to complete one operation. like one to log on, second onwards to execute calls, and the last one to log out.
(there is some cookie management also required to logon successfully into the web services).
Should we write a custom task which will fetch the data for us? Or just write a C# component which is invoked from SSIS?
Regards,
Abhishek.

Hi there,
I'm using a query to fetch data from a table where one of the criteria is IN(...) clause for the key column of the table.Now the data being retrieved is ordered by the key column of the table even though I haven't specified any order by clause.
I want to know if there a way in which the data being fetched is in the order of my IN(...) clause.
Thanx

Hi,
I am trying to fetch data from IBM DB2 to SQL Server 2005.
The problem I am facing is when I create the OLE DB Connection (I am using the "IBM DB2 UDB for iSeries IBMDA400 OLE DB Provider") and see the "Preview", I get "System.Byte[]" in a couple of columns for all the rows, instead of the actual data.
The datatype of the original field is "Byte Stream".
I have tried all options, but, failed. I believe there is something in the "Force Translate" property of the OLE DB Connection. Right now it is set to "65535". I am not sure if that needs to be changed.
I was earlier using a DTS package, where I used ODBC for connecting to the same database. In ODBC, there is a "Translation" tab where there is a check box labelled: "Convert binary text (CCSID 65535) to text".
When I check this box, I am able to see the data correctly.
But, now I have moved to SSIS and I am facing the same problem as I am not using the ODBC connection.
Please help.
Thanks and Regards,
B@ns

S/W Technologies : C#.Net 2005, ASP.Net 2005, SQL Server 2005
Greetings everyone,
Heres my code for login verification, which is written in the login button click.
SqlCommand cmd = new SqlCommand("Select uid,pass from UserRegistration where uid='" + txtuname.Text + "' and pass='" + txtpass.Text + "'", con);
con.Open();
dr = cmd.ExecuteReader();
if (dr.HasRows) { <code......> }
Now, my problem is, the SQL Server 2005 is fetching rows without checking case. For e.g. if I enter a password as "MYSTERY" or "mystery" which is stored as "Mystery" in the database. The datareader shows positive in HasRows property. So, Can someone suggest me how to fetch case sensitive data from SQL SERVER 2005. Thanks.

I'm using ODBC 3.0 in code written in C.
I have an service that connects using a system DSN using the SQL Server 2000 driver. On my development system with SQL Server 2005 Express installed, the queries work fine. I prepare a statement and then bind the columns that will be in the result set. On my system, I get all the data as it should be but on a live system, I do not get the proper data for the last three rows. I don't get any error messages from the query or the column binding and there are also no extra information messages that I can retrieve.
The table is something like the following. The names are changed to protect the guilty.
CREATE TABLE DOWNLOAD
(
FIELD_1 NUMERIC( 6,0 ),
ID CHAR( 15),
FNAME( 30 ),
LNAME( 40 ),
CLIENT_ID NUMERIC( 9,0),
CLIENT_NAME CHAR( 50 ),
CODE NUMERIC( 4,0 ),
PHONE CHAR( 10 )
)
go
On my system, running the exact same binary code as the client machine, I get all of the data from all of the columns as it should be. The problem is when I run on a client's system, the CLIENT_NAME, CODE, and PHONE columns return null values even when there is data there. On my development system the SQL Server instance runs on the same machine. On the client's sytem I am connecting to a remote instance of SQL Server 2000 on another system on the network.
My quandry is what could be different between the two systems that is causing me the problems?

Hi there,
i have a task that has a ole-db destination. it inserts some data to a table. it's always 1 record that is gonna be inserted.after that the task is finished. however i want to use that same record in the followup-task. is there a way to retrieve the id of that specific record.
Please note that the id of the record is an int-identity from sql-server itself.
at the moment i'm fiddling with "remembering" the inserted data and hopefully it will be a 100%match in the next task, but i have a dark feeling it's not 100%.
is there a common way how to approach this?

Hi all,
While I was testing our application installation on Vista, I ran across this problem:
When a program on Vista is executing a SPROC is a SQL Server on Vista (actually same machine), the SQLFetch(m_hstmt) returns a SQL_NO_DATA.
When the exact same program is executed on XP SP2 client against the same Vista based SQL Server, it correctly returns the rows.
The build of the program was done on a MDAC 2.8 XP SP2. When I tried to install 2.8 on Vista machine it seemed to have failed.
Using DSN vs. DSNless connection string made no difference. Nothing of intest in SQL Logs either.
Any clues?

I want to fetch definitions for all stored procedures & views in a database.
For stored procedures, I use sp_stored_procedures to retrieve all SPs & then use Procedure_Name column to fetch each SP's name followed by a call to OBJECT_DEFINITION to retrive its definition.
Now, I have found 'sp_views_rowset2' that returns all views. As I am not very sure about it, this is just for confirming that the task of 'sp_views_rowset2' is actually to return all views defined for the database!!!

Hi,
I get 5000 records on executing a query.
In the form, I would like to display 50 records at a time in the grid from this resulted query, so i create 100 link labels(dynamically created based on the no. of records resulted from the query) within a panel.
When clicked on link1, first 50 records should be displayed,on clicking link2 next 50 records(ie, 51 to 100) should be displayed and so on.
So , i wrote the query as---
select top(50)* from tblindividual where id not in (select top(intValue)id from tblindividual )
where intValue would be 50 for link2,100 for link3,150 for link4 and so on
If i want to fetch last 50 records of the query, intValue would be 4950.Here the "not in" list becomes very big(1,2,3,.......,4949,4950) and hence the query is becoming a bit slow...
Is there any other method(query) to get the same result??.. because i heard that using "not in" keyword would make query execution slow.

Have a table with following structure
ID DeviceName Status
1 Sony Good
2 Toshiba OK
3 Sony Bad
4 Tata OK
I need to return the following records
ID DeviceName Status
2 Toshiba OK
3 Sony Bad
4 Tata OK
If there are more than one record for the Device, then record with the latest ID should be returned.
If there is only one record for the Device, then that record should be returned.
Can this be achieved through a single query.
Any help is appreciated.

Hello folks,
I have a table, say T1 and this has a child tabel named T2. The common column between the tables are say COL. Now the scenario is there are multiples of records in the T2 for each record in table T1.
Now when i make a join of both the tables, say INNER JOIN, it returns the number of records based on the child table. i.e. say for a record in T1 there are 3 records in T2. Then through the INNER JOIN i will be getting the 3 records. But need only one record from the join. Have tried with "SET ROWCOUNT 1". But as you all know that this will not work. Kind suggest me the way friends........:eek: :eek: :eek:

Can I do something like this in RS -
I would like to call a function in a calculated field like
=code.GetNHW(Fields!id1.Value,Fields!date1.Value)
where the GetNHW() function would return a double value based on some conditions-
The code I would like to write in Code window-
Public Function GetNHW(ByVal ID As Integer, ByVal attDate As Date) As Double
Dim dsDTConfig As New DataSet
Dim NHW As Double
dsDTConfig = GetDS("tblEmployee_DailyTimingsConfig", "id=" & ID & " and '" & attDate & "' between configStartDate and configExpiryDate", False)
If dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = True Then
NHW = 0.01
ElseIf dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = False Then
NHW = 0.05
End If
Return NHW
End Function
What I am looking for is - I would want to get the record(dataset) within the function from the database
and based on the values got, I would check few conditions and calculate NHW.

Hi,
I get the following error.
Err.Description - "Rowset does not support fetching backward."
Err. Number - -2147217884
Can somebody tell me the reason behind this error.
My Reasearch: I have got to know that I get this error in the line of code recordset.MoveLast in My code.
My Code environment: I have built an SQL Query string which calls the Strored procedure with one parameter (parameter tyoe is string type). I have attached the SP code below.
and SP contains the call for querying other database in the same server using OPENQUERY command.
and the VB code contains code as Recordset.MoveLast. (Error is generated here and Recordset.RecordCount is also -1)
SP code is:
Code Block
CREATE PROCEDURE [dbo].[sp_RMS]
@sRMS_Status CHAR(12)
AS
BEGIN
DECLARE @sSQL VARCHAR (1000)
SET @sSQL = '''SELECT *
FROM VW_JOKE
WHERE JOKE_ID = ''' + '''' + @sRMS_Status + '''' +
''' ORDER BY JOKE_NO''
EXEC ( 'SELECT * FROM OPENQUERY(lnk_joke__cat,' + @sSQL + ')' )
END
My Questions:
1). Is there any problem in SP as I am using OpenQuery? I queries the SP and concluded that it generates result properly.
2). Is there any problem with the Recordset.MoveLast line? I am using adOpenKeyset, adLockReadOnly as parameters to my Recordset.Open command along with other parameters.
Let me know the corrective steps to be taken to get rid of this error.
Thanks in Advance for your valuable time

I wrote a bat file to start a sql job using dos command
osql -S “[SQL SERVER NAME]” -E -Q”exec msdb.dbo.sp_start_job ‘[SQL JOB NAME]'”
[URL]
now this bat file only start the job, does not wait for it completion or send us the success or failure message.Now i want to check the value of LastRunStatus for this job using BAT file?? Is is possible to fetch the LastRunStatus of sql job using bat file.However i have achieved the same using vbscript that starts a job using vbscript start method and then looping through al the jobs at server and displaying the LastRunStatus. However i wanted to achieve this uisng bat file only.
