Question On Data Retrieval Using RDA Pull
Jun 3, 2008
Hi All,
I am working on an application to retrieve data to the windows ce 3.0 handheld from the Sql server database. I am able to retrieve the data from the server using RDA pull method and able to see the data on the local handheld database. To display the retrieved data in the dialog to the user, it requires to query the local databse and get the information and then display the information, which is taking some time.
My question is, to reduce the time and improve the performance , instead of pulling the data to the local table, is there any way to pull the data and have it in memory and display the details to the user?
To develop the above application, I used some of the code to pull the data from the server from the sample application C:Program FilesMicrosoft SQL Server CE 2.0SampleseVCeVCReplRdaHPC. I am developing the application for windows ce 3.0 device using eVC 3.0
thanks
pyd.

Code Block
string commandString = "SELECT Id,Name FROM [DatabaseTable];";
using (SqlConnection conn = new SqlConnection(connectionString))
{
SqlCommand cmd = new SqlCommand(commandString, conn);
conn.Open();
IDataReader rdr = cmd.ExecuteReader();
IList ids = new List();
IList names = new List();
while (rdr.Read())
{
ids.Add((int)rdr[0]);
names.Add((String)rdr[1]);
}
rdr.Close()
}
What i want to know is if there is any better way of obtaining the 'id' and 'name' data
values then just assuming that id is the first returned object and name is the second returned object in each reader record.
ie. Is there any way to retrieve a specific field from the reader in a Dictionary-type manner...?
Code Block
while(rdr.Read())
{
ids.Add( (int)rdr["Id"] );
names.Add( (String)rdr["Name"] );
}

Hi,
I'm using ASP.NET 1.1, SQL Server 2000 Server:
I followed the ASP.NET 1.1 Starter Kit's Commerce application and applied the same principles it had written the code to retrieve data to my web application I created. For example I've written this Function in a class to return a sqldatareader:
Public Function GetAdvanceSearch(ByVal s As String, ByVal Ext As Integer, ByVal fdate As DateTime, ByVal tdate As DateTime) As SqlDataReader
Dim oDrAdSearch As SqlDataReaderDim oCmdGetSearch As New SqlCommand("spAdvanceSearch", oComConn)
With oCmdGetSearch .CommandType = CommandType.StoredProcedure .Parameters.Add(New SqlParameter("@DialNo", SqlDbType.VarChar)).Value = s .Parameters.Add(New SqlParameter("@FDate", SqlDbType.DateTime)).Value = fdate .Parameters.Add(New SqlParameter("@TDate", SqlDbType.DateTime)).Value = tdate .Parameters.Add(New SqlParameter("@Ext", SqlDbType.Int)).Value = ExtEnd With
oComConn.Open()oDrAdSearch = oCmdGetSearch.ExecuteReader(CommandBehavior.CloseConnection)
If oDrAdSearch.HasRows Then Return oDrAdSearchElse Return NothingEnd If
End Function
And When I'm calling this function I do write in this way (assuming that this function is in a class called "Calls"):
Dim objCalls as New Calls
DataGrid1.DataSource = objCalls.GetAdvanceSearch(<PARAMS.......>)DataGrid1.Databind
My application is a Telephone Call Recording System and could expect vast amount of data. Averagely, a month may produce approximately 50,000 records or more. So while querying through my web application for a month, the application itself either gets stuck or the retrieval speed gets drastically slow. However I'm using Datareaders for every querying scenario. My Web application is hosted in a Windows 2000 Server and accessed via Local Network or IntraNet.
What are the ways I could make this retrieval more speedier and efficient? I would like to hear from anyone who have come across this problem and anyone who could help me on this.
Thanks in Advance. Looking forward for a reply from some one.

Hello all,
I'm stumped on how to solve this question so I figured i'd ask the community. As a warning i'm not sure best how to describe my situation so i'll try and give as much detail as I can.
First in table A, I have two columns that already have data in them that are numeric (Col1, Col2). Also, in table A I have two more columns that are going to derive their data based of a complicated data retrieveal routine (Col3, Col4). So my table structure looks something like this:
Code:
Table A
Col1 Col2 Col3 Col4
20 20 NULL NULL
(Where Col3, and Col4 are going to be populated based off the routine)
The Data for Col3 and Col4 is in an excel spreadsheet that i'd like to convert into a table for MSSQL. However i'm not sure how to do this because in the spreadsheet there is a lookup routine (that i'm trying to copy to MSSQL code, i'll show that in a minute) that generates its values based off data in the X / Y columns, so something like this:
Code:
_|1__|2___|3__
0|0 |0 |0
1|1 |15 |25
So when 2 is met, and 1 is met, they would equal '15'. No arithmetic involved, just simply matching up the X / Y and pulling the data.
My question is, how do I create tables out of this, so my lookup routines can get the values as a result of matching X / Y? (2, 1 = 15)???
The excel routine is this:
=IF(VLOOKUP(F66,'Appendix A'!A5:K56,MATCH(F68,'Appendix A'!A4:K4,1),TRUE)>F46/12*0.125,F46/12*0.125,(VLOOKUP(F66,'Appendix A'!A5:K56,MATCH(F68,'Appendix A'!A4:K4,1),TRUE)))
Thanks!

Hello,
i am getting a hard time in minimizing time for data retrieval, over SQL Server DataBase. My DataBase consist of 2 tables. One of the table has more than 10000 entries and other table with more than 10 million entries. I have used SQLNative Client for connecting to data base and my goal was to find a value from the 1st table and search it out in 2nd table. The result is more than hundered thousand rows. Now the problem is: the time it took for retrieving those rows is much slower approx. 12 minutes. Can this time be cut down. I have used SQLClient connection to make sure it is accessing SQL server on a direct access base.
Also, i am using
SqlClient::SqlDataReader
for reading, getting rows returned by the my query.
Please help me out.
Thanx.

A call to a stored procedure completes in 13 seconds when ran from within SQL Server Management Studio. A report whose data source uses the same stored procedure can take as long as 10 minutes to run. The same parameter values are used in both the direct call and the report. The execution log says almost all of that time is spent on data retrieval. How could that be? What might be the cause?

Hi there,
I was wondering if someone could propose a solution for the following scenario:
TimeID column would have values from 1 to 6 and rows will be inserted only for those timeIDs where we have Data value as well. While retrieving data we would like to have all timeID range returned with explicitly specifying NULL for missing Data column. Please see below to better understand the situation.
create table test
(
TimeID INT,
Data INT
)
INSERT INTO test VALUES(1, 100)
INSERT INTO test VALUES(2, 180)
INSERT INTO test VALUES(4, 550)
INSERT INTO test VALUES(6, 120)
select * from test
1 100
2 180
4 550
6 120
Desired resultset
1 100
2 180
3 NULL
4 550
5 NULL
6 120
...

Hi,I wonder if anyone can help with the following on a fee paying basisfor the the design or development of some type of script or utility orpiece of code to do the following work.I wish to retrieve some data from an online database that is in thepublic domain. The online database has a search facility that matchesthe entry (name) in a search box then returns a screen stating that amatch has been found or not found.If a match is found there is a button to click that proceeds to thescreen containing the data which is simply two names. It is these twonames that I wish to retrieve and store them in something like a textfile where they are associated with the original entry (name) used inthe search box.I have a list of the entries for the search box that can be suppliedin sample format for testing as a columnar text file or commadelimited file or a spreadsheet.. I would need the procedure toprocess the list of search entries, retrieve the data then move on tothe next one in the list. Obviously, if a match was not found then theprocess would need to move on the the next entry in the list withperhaps a message saying "No Match" until the entire list wasprocessed.The PC I hope to run the process on is a Windows XP machine and if Ineed to purchase any particular software that is necessary for the jobthen I am quite willing to do so. Also, as I pointed out above I wouldpay for the work to be done.I hope that I have explained the above OK and that I have posted it tothe correct newsgroup(s). If it is not in the correct newsgroup Iwould be grateful if anyone could point me in the right direction.RegardsDave Gibson

Hi all,
I have following problem:
I'm developing a Windows Mobile application, which is using RDA Pull for retrieving data from SQL Server 2005 database to PDA. Please, see the example:
Code Snippet
using (SqlCeEngine engine = new SqlCeEngine(connStr))
{
engine.CreateDatabase();
}
serverConnStr="Provider=SQLOLEDB;Data Source=.;User ID=sa;Initial Catalog=Demo;Password=xxx";
using (SqlCeRemoteDataAccess rda = new SqlCeRemoteDataAccess(
Configuration.Default.SyncServerAddress, "", "", connStr))
{
rda.Pull("MyTable", "SELECT * FROM mytable", serverConnStr, RdaTrackOption.TrackingOffWithIndexes, "ErrorTable");
}
Everythink works fine, when I use 'sa' user account in serverConnStr.
But, when I change conn string to:
"Provider=SQLOLEDB;Data Source=.;User ID=test;Initial Catalog=Demo;Password=test"
the sqlcesa30.dll cannot connect to SQL Server database.
In the sqlcesa30.log then I found following line:
Code Snippet
2007/04/17 10:43:31 Thread=1EE30 RSCB=16 Command=PULL Hr=80040E4D Login failed for user 'test'. 18456
The user 'test' is member of db_owner, db_datareader and public roles for the Demo database and in SQL Server Management Studio I'm able to login to the Demo database with using the 'test' users credentials and I'm able to run the select command on 'mytable'.
So, what's wrong? Why the sqlcesa30.dll process cannot login to the Demo database, and from another application with using the SAME connection string it works?
Please help.
Thank you.
Fipil.

I have a cluster hosting multiple GP databases and a second for my data-warehouse I am playing around with (personal project).
I have scripts that pull data from all the DB's to input into the DW's tables(Customers,Reps,Hub....)
An example of my branch script :
select interidas BranchID,
cmpnynamas BranchDesc,
address1as BranchAddressLine1,
address2as BranchAddressLine2,
address3as BranchAddressLine3,
zipcodeas PostalCode
from dynamics..SY01500
Where interid in ('comp1', 'comp2', 'comp4', 'comp5')
what would be the best way to using these scripts pull the data to my testDW and not have duplicate data issues?
I was thinking of using a staging DB on the GP cluster and then building an import data package to run nightly. the issue i had was how do i avoid duplicate data ?

I am trying to create a report with a sub report in Sql Server 2012 using Report Builder Version 3. I can run the subreport without any problems. I read where using a shared connection can cause this error so both the main report and the subreport use a connection that is embedded in my report.
For testing, I created the subreport without a parameter and added it to the main report. When I ran it that way, the report worked and sub report displayed the data. So I know it can read from the database.It seems to only give me this error when I am trying to tie the two reports together using a parameter.

Hi,
Writing a report that displays total hours, etc for each day in a given month and I'm having trouble comking up w/ an elegant solution. Tables are set up like this:
table1 (id, start_date,end_date,submitter)
table2( id,table1_id,start_time,end_time, etc)
Each record in table2 is a child to a parent record in table1 and there may be multiple children for each parent. The "start_time" and "end_time" fields are datatype "datetime" and are stored with actual times (not 12:00:00 AM"). I need the report to display the values for each day in a gridview, etc so I can act upon them from the "RowDataBound" sub (more math, etc). The problem that I am running into is that for records that have multiple children for a given day, I need to sum those results and display the summed data as a single row within the GV - can't seem to work that out - I keep getting every child record displaying as its own row in the GV.
Any thoughts? I'm sure it's probably fairly simple but I am still a beginner...thanks as always

Hello -
I am trying to pull data from SQL Server 2000 database onto my Pocket PC and the simple query works on Northwind sample database but does not on another custom build database. I did test the statement in the SQL Query Analyzer and it works.
The error I get is: "Failure setting up a non parameterized query, possible incorrect SQL query."
I know the code is right - thanks to Rory B's screenscasts. Any guidance will be greatly appreciated!
Thanks!

Here is the code:
private void RdaPull()
{
try
{
//Create the database
if (File.Exists("\My Documents\Test.sdf"))
File.Delete(\My Documents\Test.sdf);
SqlCeEngine engine = new SqlCeEngine();
engine.LocalConnectionString = localConnection;
engine.CreateDatabase();
engine.Dispose();
//Initialize RDA Object
SqlCeRemoteDataAccess rda = null;
rda = new SqlCeRemoteDataAccess(rdaUrl, localConnection);
rda.Pull ("Customers", "select * from Customers", rdaOleDbConnectionString);
rda.Dispose();
MessageBox.Show("Done");
}
catch (SqlCeException ex)

MessageBox.Show(ex.Message);

Hello Everybody,
I have a small tricky problem here...need help of all you experts.
Let me explain in detail. I have three tables
1. Emp Table: Columns-> EMPID and DeptID
2. Dept Table: Columns-> DeptName and DeptID
3. Team table : Columns -> Date, EmpID1, EmpID2, DeptNo.
There is a stored procedure which runs every day, and for "EVERY" deptID that exists in the dept table, selects two employee from emp table and puts them in the team table. Now assuming that there are several thousands of departments in the dept table, the amount of data entered in Team table is tremendous every day.
If I continue to run the stored proc for 1 month, the team table will have lots of rows in it and I have to retain all the records.
The real problem is when I want to retrive data for a employee(empid1 or empid2) from Team table and view the related details like date, deptno and empid1 or empid2 from emp table.
HOw do we optimise the data retrieval and storage for the table Team. I cannot use partitions as I have SQL server 2005 standard edition.
Please help me to optimize the query and data retrieval time from Team table.
Thanks,
Ganesh

Good Afternoon,
I have recently been tasked to come up with a means by which to create SQL data pulls based on user entries. What I mean by this is, I will have a pre defined SQL data pull set up and the user can then select the criteria upon which to pull said data.
So, say I want to display a table where one of the colums has is the "Year". I dont however want all years of data pulled, only 2005 - 2006. So, in form field 1, I could select start year as 2005 and in form field 2, I could select end year as 2006. This would then give me all data from this table based on that year range, or whatever year range I select and submit.
Is there a way to do this in ASP? I have been reading up on UDF with SQL, but I cant find anything about linking it through the use of web forms or through ASP. Or if there is another way to accomplish this? Any assistance is very much appreciated!

I have an OLAP server and would like to use my Chart FX software without having to purchase the OLAP extensions on the server due to budget restraints (ouch).
I've heard that it is possible (although limited) to attach toan OLAP cube using SQL select statements (not MDX).
Basically, I would like to pull the OLAP data in the relational sense.
Is this possible? If so, are any good articles on this subject?
I'm new to OLAP and would like to transition slowly.

When someone add another line in SQL against an order or a customer then manually added columns data goes out of sync.Is there anyway when I refresh the RAWDATA or anything changes on SQL table then it should sync my formatted worksheet.

I am trying to create a query that will pull a variety of data from three different tables. I've had to join four tables because one set of data is in a completely different table.
I am expecting one row of data but instead I get 4 rows. I suspect this is because I am joining a table indirectly. Here is the code:
SELECT
SDH.BatchID,
('0' +
CONVERT (varchar (10), SDH.WorkerID)) AS VendorID,
convert(varchar,( dateadd(hour,-1,SHIT.EndDate) ),101)
+ ' - ' + SDH.Description
[Code] ....
There is only one applicable row in SDH, but four rows appear when I run the query. All four rows are identical except for the GL.GLCode column, which lists the three GL codes associated with the DeductionItems table. The fourth row is a duplicate of the third.

Hi,
I am trying to use RDA.pull to pull data from SQL server 2000 to sql mobile, but it fails when some columns are included in the SQLSelectString, though the datatypes involved are only char, float, smallint and smalldatetime, and nothing is longer than 30. Since there is a very large number of columns, it is difficult to isolate the guilty one by trial and error! Coud someone please help?

I am building RDA process between SQL server and SQL server CE. Since when we use the method 'SqlCeRemoteDataAccess.pull()', the data will be pulled down from SQL server to CE server and a new table is created with some addtional columns. As I only intend to pull the data and never push it back to SQL server, if I pull the data down for the second time, there will be an error saying that table is already existing. I wonder whether I can pull the data to an existing table everytime I do the RDA?
