Inserting Dataset Values Into SQL Mobile Using C#
Apr 14, 2006
Hi,
I have developed an application where i am inserting all the records from the dataset into sql mobile 2005. Dataset contains a primary key which is an uniqueidentifier datatype. While inserting the data it is inserting properly into the database but it is changing the value of primary key which is in the dataset.
I am using the below syntax, please suggest me so that to avoid creating a different uniqueidentier key into the database.
conAdap = new SqlCeDataAdapter(strQuery, conSqlceConnection);
SqlCeCommandBuilder cmdBuilder = new SqlCeCommandBuilder(conAdap);
conAdap.AcceptChangesDuringFill = false;
conAdap.Fill(dsData);
conAdap.MissingMappingAction = MissingMappingAction.Passthrough;
conAdap.InsertCommand = cmdBuilder.GetInsertCommand();
conAdap.InsertCommand.Connection = conSqlceConnection;
int r =conAdap.Update(dsData.Tables[0]);
Thank you,
Prashant Mulay

I have five small tables that I need to insert to a SQL CE database.
I am using the 2.0 Compact Framework with the 2.0 System.Data.SqlServerCe.
My table definition is dynamic so I never know it's design.
1- If I go Row by Row using an this.ExecuteNonQuery(_global, par); it takes about 26 seconds to insert 5 tables of 330 rows.
2- If a use
StringBuilder sbColumns = new StringBuilder();
foreach (DataColumn dc in table.Columns)
{
if (sbColumns.ToString() != "")
sbColumns.Append(",");
sbColumns.Append(dc.ColumnName);
}
SqlCeDataAdapter da = new SqlCeDataAdapter("SELECT " + sbColumns.ToString() + " FROM " + _tablename, m_con);
SqlCeCommandBuilder cb = new SqlCeCommandBuilder(da);
da.MissingMappingAction = MissingMappingAction.Passthrough;
da.InsertCommand = cb.GetInsertCommand();
da.Update(table);
da.Dispose();
it takes about 46 seconds.
How Can write it faster or is this fastest it can go?
Thanks

hi,
I have developed an application in c#.net 2.0 for Pocket PC. And even i developed a webservice to communicate between sql server 2005 and sql mobile 2005. Webservice returns the data in a dataset format from sql server 2005, but while inserting the data row by row from dataset, it is taking a huge amount of time. I would like to know, is there any way where i can copy the bulk data from dataset into the sql mobile 2005 using c#.And how this can be achieved.
Thank you

Hi,
I have two datasets in my report, D1 and D2.
D1 is a list of classes with classid and title
D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.
I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.
Is there any way to do this in RS2005?

I am running VS 2005 Professional Edition
Windows XP profession with Service Pack 2
SQL Server 2005 Developer Edition.
WHAT I HAVE DONE:
I have a database running in an instance of SQL Server.
I set this up for merge publication and then set up a SQL Server Mobile Edition Subscription to that publication. After a few oversights I got everything working. The Mobile database replicated just fine. I went back verified all data was there. Can make queries to it.
PROBLEM:
I set up a new dataset to use tables from the SQL Server Mobile database. If I drag one of the tables to the dataset, VS 2005 simply stops responding. It is not using any processor. I click any place on the application and I get the Microsoft Visual Studio Delay Notification saying:
Microsoft Visual Studio is Busy.
Microsoft Visual Studio is waiting for an internal operation to complete. If you regularly encounter this delay during normal usage, please report this problem to Microsoft.
Well... It is more than just a delay. The environment is not using any processor its just sitting here. And I left it running for 2.5 hours... so now this is becoming a big source of pain for me because I need to get that dataset working to finish my business logic. The only option I have is to Kill the process.
Hopefully someone out there can help.
Additional Services running:
IIS (Whatever version comes with Windows XP Pro. I think 5.1)
SQL Server Agent, SQL Server Integration Services, SQL Server Broswer and SQL Server FullTextSearch
UPDATE: I am editing this post with an update.
I noticed that my other tables get added to the dataset just fine. It is when I add one particular table that the entire visual studio simply stops and starts giving the delay notification. I have no idea why this happens... nor do I see any noticeable difference between this table and the rest of them. I went back and made sure that all columns types where directly supported by SQL Mobile Edition and they are.

Hi there, I'm using CF2.0 SP1, with sqlce.
I have a 5MB delimitered file with 60,000 rows.
I need to insert it into a table in the PDA.
Once I start the procedure that inserts the table, the PDA's memory drops by 20-30 MB and every once in a while i get a
"Out OfMemory" exception...
Basically I send an insert command for every row in the text file cause last time i've checked, multiple rows insert per call wasn't yet implemented in the Sql Mobile...
Correct me if i'm wrong...
Code Block
StreamReader sr = new StreamReader(file, System.Text.Encoding.GetEncoding(1255));
line = sr.ReadLine();
clsAceProduct ace = new clsAceProduct();
//Read the first line of text
//Continue to read until you reach end of file
while (line != null)
{
//Send the Insert SQL Command
ace.Fill(line.Split(x));
bInsert=InsertAceProduct(ace);
if (bInsert)
{
l++;
}
//Read the next line
line = sr.ReadLine();
Thanks.

Howdy,
Am having an issue using a dataset returned from a web service method. The webservice grabs data from a desktop SQL server database and returns it as a dataset.
I can call the web service fine and load the dataset into a datagrid (testing purposes). etc
However am having an issue with inserting the dataset data into the Windows CE Database.
Web Service Method
<WebMethod(Description:="Query a database. Returns a dataset.")> _
Public Function GetData(ByVal connectionString As String, ByVal selectcommand As String) As DataSet
Dim ds As DataSet = New DataSet()
Dim connection As SqlClient.SqlConnection = New SqlClient.SqlConnection()
Dim Command As SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand()
Dim DataAdapter As SqlClient.SqlDataAdapter = New System.Data.SqlClient.SqlDataAdapter()
connection.ConnectionString = connectionString
connection.Open()
Command.Connection = connection
Command.CommandText = selectcommand
DataAdapter.SelectCommand = Command
DataAdapter.Fill(ds)
Return ds
End Function
Insert Code
Dim ds as new dataset
ds = x.GetData("Data Source=Stephen01;Initial Catalog=BoxDB; uid=ste;pwd=1234;", "Select * from Swipes")
Try
For Each dr As DataRow In ds.Tables(0).Rows
db.Update("INSERT INTO Swipes (CardNo,Jobcode,ClockedAt,ClockType) VALUES(" & dr.Item(0) & "," & dr.Item(1) & "," & dr.Item(2) & ",'" & dr.Item(3) & "')")
Next
db.Close()
Catch ex As Exception
MsgBox(ex.ToString)
End Try(All Values are int's except Dr.item(3) which is a datetime field)
The when i click this button i get the error.
"Data Conversion Failed. [OLE DB status value (if known) = 2]"
I am guessing this is an issue to do with the date but to be perfectly honest i have no idea. Wish CE errors were more indepth!
Thanks

Hi,
I am mapping an entity from SQL 2005 to another entity in another system on SQL 2000. Since the destination system has its own ID generator, I want to keep the generated ID for each row of my table in a column of my table in SQL 2005. The new column is in the dataset now , but I don't know how to update my table to have that column values (The OleDbDestination just insert new items.)

What would be the best way to insert unique values into a table/unique column ?
I cannot make that table/unique column as indentity. Right now, I use a staging table with indentity column, insert rows then insert rows back to
final table.
Suggestions are much appreciated.

C# .Net Application as front end
Sql Server2000 as back end
I need to merge an external dataset from .Net app(in XML format) with the information in database with one column in database table as the merging criteria. A situation similar to Left Outer Join, wherein i need all records from external dataset and if matched in database the corresponding values from there too, the only difference here is that the join is not between two Tables its between a table and external dataset.
There is no need to store the external dataset in the database in persistent form, its just a query - merge - response operation.
So, can anyone suggest the best possible solution for this? A table variable / temporary table / some other schema, what and how?
Thanks in advance..

I am using RDLC report with Microsoft visual studio 2005. In the first page of rdlc i have two text boxes and one table in body section. In the second and subsequent pages i want to repeat the data from textbox1 and textbox2 along with table data continuation of page1.
Currently the continuation of table data from page1 to page2 is working properly. But the textbox1 and textbox2 data also needs to be repeated in every pages.
I tried the following steps, but fails to work.
1. added two text boxes in header section and another two text boxes in Body section.
2. Assigns the dataset value to textboxes in body section.
(Ex: =first(Fields!Address.Value)
3. Assigns the textboxes value from Body section to the corresponding text boxes in header section.
(Ex : =first(ReportItems!textbox1.Value))
Result:
The header text box value displayed in the first page only and not repeated in the subsequent pages.
Expected:
Whatever assigned to the header section should be repeated in the subsequent pages. But only page number, date... is reflecting in other pages and not the text box values in header section.
Kindly give me the solution.
Thanks in advance.

Hi.
In my report, I need to display column names (and its values) from my dataset, which uses the stored procedure and within it use the PIVOT statement. I cannot use the matrix control in report since I need to add another static column to the right of the matrix, but since that cannot be done ni SQL SSRS 2005, I need to PIVOT it through stored procedure. The parameter passed to stored procedure is the year and it is used for pivot. The statement looks like this:
@sql = 'SELECT * FROM (SELECT YearId, SchoolId, ReportText, OutputValue_Text from AggregateTable) AS AGAM
PIVOT (MIN(OutputValue_Text) FOR YearId IN ([' + @YearId + '])) PVT'
EXEC(@sql)
So, since the years passed as parameters can change, I cannot hard-code it as column in my report, so I need to programatically display column names and values from my dataset, something like dataSet.Tables[0].Columns[].ColumnName; I have tried with writing the code, but I do not have much experience with it and I have not been very successful. Can someone help me with the code?
Thanks

I need to insert some values into a table and after that catch the ID inserted.
I set some input parameters in stored procedure and only one to get the @id defined as output
SqlParameter paramIdPedido = new SqlParameter("@APP_IDPEDIDO", SqlDbType.Int, 4);paramIdPedido.Direction = ParameterDirection.Output;cmd.Parameters.Add(paramIdPedido);
Do I have to run cmd.ExecuteNonQuery(); to record first what I need and afterrun ExecuteReader: something like SqlDataReader dr = cmd.ExecuteReader();while (dr.Read()... to get the ID)
From stored procedure:
INSERT table(fields) VALUES(vars)SELECT TOP 1 @id = id FROM table ORDER BY id DESC
I must do all these steps or maybe is there anything less complex to do?
Thanks!

Hi,
I am trying to insert multiple values from another table as well as an addition value defined by me. Here's my code which is obviously incorrect at the AND statement:
Insert Into table_1 (ID, Col_1, Col_2)Select ID, Col_A, Col_B From table_A AND table1.Col_3 = 'XYZ'
Where table_A.Col_A IS NOT NULL
Pls advise on the correct way of constructing this statement.

Hi all,
I am having issue with a set of radiobuttons. I have four radiobuttons associated by a groupname (answer). I am attempting to store the text of the selected radiobutton when the user make a selection and clicks submit. For reasons unknown... each of the radiobutton.checked values are remaining false hence I cannot interrogate for a checked equal true to insert associated text of check response.
Here is how I am interrogating who is checked:
If rb1.Checked = True Then
useranswer = rb1.Text.ToString
ElseIf rb2.Checked = True Then
useranswer = rb2.Text.ToString
ElseIf rb3.Checked = True Then
useranswer = rb3.Text.ToString
ElseIf rb4.Checked = True Then
useranswer = rb4.Text.ToString
End If
I then attempt to insert this text to sql but none of the rb values are true hence a null wont insert.
Cmd1.Parameters.Add(New SqlParameter("@answer", useranswer))
How can I evaluate grouped radiobutton checked values?
Many thanks in advance...

Hi All, am new to sql server in my application I am having one Asp.net web page, the user has to enter values for 5 fields(Empno,Empname,salary,deptno,deptname) in that web page and for that i created two tables in sql serverEmp Table- empno(primary key),empname,salaryDept Table- Deptno(primary key),empno(Foreign key ),Deptname(with some check constraint.) After the user enter all the values in the Asp.net web page now i want to store data into database for that i wrote the following stored procedure...create procedure usp_EmpDept @empno integer, @empname varchar(15), @salary money, @deptno integer, @deptname varchar(10) As Insert into emp(empno,empname,salary)values(@empno,@empname,@salary) Insert into dept(deptno,Empno,deptname)values(@deptno,@empno,@deptname) but the problem is whenever some constaint violation for eg. if some check constraint violation in Dept table its inserting the values in the Emp table only, but my requirement is, It must enter into both tables if there is no constaraint violation otherwise it has to ignore both the tables. And also please suggest is there any better way to insert values into two tables other than using the stored procedure Any help will be greatly appreciated..Thanks,Vision..

Is there a way to insert multiple values into a single column based on various "tests".
For example, I want to check a sales_order table and flag all new orders coming in against previous orders placed that were determined to be fraudulent. If I were to set up i.e. five different tests(i.e. check email, credit_card number etc. against previous fraud orders), then there would be the possibility that any given order can be flagged 1 to 5 times. I want to record all of these tests within the same column if possible. Therefore the output may look something like the following:
order_number fraud_score
1234567890 a,b,d
5432109876 e
2345678901 null
3455607983 a,b,c,d,e
I was considering adding five additional columns to the table and running five different update steps, but this doesn't appear very scalable. Any suggestions would be greatly appreciated!
thanks in advance-
