I have a url in xml format.
Sample xml file format is as following:
<shows>
<show>
<eventID>10025</eventID>
<name>MARCH Barrel</name>
<ticketURL></ticketURL>
<venue>
<venueID>3648</venueID>
<name>Double Barrel</name>
<address>3770 Las Vegas Blvd. South</address>
<address2></address2>
<city>Las Vegas</city>
<state>NV</state>
<zipcode>89109</zipcode>
<country>US</country>
</venue>
</show>
</shows>
Question:
How, is it possible to store venueID & name in sql server 2008 using C#, as I have a table which contain this type of field ?
You can store information in SQL Server XML type field. Following article contains complete information for how to use XML datatype in sql server.
https://www.simple-talk.com/sql/learn-sql-server/working-with-the-xml-data-type-in-sql-server/
SQL Server 2005 and up have a datatype called "XML" which you can store XML in - untyped or typed with a XSD schema.
You can basically fill columns of type XML from an XML literal string, so you can easily just use a normal INSERT statement and fill the XML contents into that field.
OR
You can use the function OPENXML and stored procedure sp_xml_preparedocument to easily convert your XML into rowsets.
EDIT: Try This
String xmlFile = #" <shows>
<show>
<eventID>10025</eventID>
<name>MARCH Barrel</name>
<ticketURL></ticketURL>
<venue>
<venueID>3648</venueID>
<name>Double Barrel</name>
<address>3770 Las Vegas Blvd. South</address>
<address2></address2>
<city>Las Vegas</city>
<state>NV</state>
<zipcode>89109</zipcode>
<country>US</country>
</venue>
</show>
</shows>";

I am using asp.net VB and I have an XML file containing a set of data, I would like to use it in something like a datalist and where usually you would use a database i would like to use the XML file to produce the information.
Does anyone know how to do this, i have read about transform files but surely i will format the information in the control?
The file has multiple records so in some cases i would need to perform queries on the information through the datasource.
I would maybe look into XML serialization and de-serialization. Using de-serialization you could read your XML into a List(T) object containing a list of your own class objects and use that as a data source for your application.
Heres a link that you may find useful:
http://msdn.microsoft.com/en-us/library/ms731073.aspx
Hope this helps.
Dim ds As New DataSet()
ds.ReadXml(MapPath("data.xml"))
First you have to parse the XML and store that into custom C# object or you can directly pass the XML to your stored procedure and do the codding there for saving it into DB.
Passing the xml to stored procedure and manipulating it there is bit difficult so what I suggest is to parse it in C# and then get a custom object. Once you get it you can do whatever you want to.
Below is the sample code that parse a XML file and generate a custom C# object from it.
public CatSubCatList GenerateCategoryListFromProductFeedXML()
{
string path = System.Web.HttpContext.Current.Server.MapPath(_xmlFilePath);
XDocument xDoc = XDocument.Load(path);
XElement xElement = XElement.Parse(xDoc.ToString());
List<Category> lstCategory = xElement.Elements("Product").Select(d => new Category
{
Code = Convert.ToString(d.Element("CategoryCode").Value),
CategoryPath = d.Element("CategoryPath").Value,
Name = GetCateOrSubCategory(d.Element("CategoryPath").Value, 0), // Category
SubCategoryName = GetCateOrSubCategory(d.Element("CategoryPath").Value, 1) // Sub Category
}).GroupBy(x => new { x.Code, x.SubCategoryName }).Select(x => x.First()).ToList();
CatSubCatList catSubCatList = GetFinalCategoryListFromXML(lstCategory);
return catSubCatList;
}
Currently I'm calling RDLC report in asp.net application, where .rdlc is calling and we passing a data source and report in generated as PDF, the entire process initiate on a BUTTON click and report is generate.
Now this process need to automate and report should generate on Monday morning.
There is some suggestion come out that we can use SSIS Script Task and we can call external DLL and can call .rdlc file too to generate the report and then we can schedule SSIS package?
I never having experience on SSIS side, need your suggestion and how to do that, if there is possibilities? Thank You!
Use SSRS to schedule the report to run. No need for ASP.net or SSIS, SSRS has scheduling built in.
You can use SSRS subscription to send the report. If you really want the SSIS to send the report. you can do the following.
Create the report in SSRS
Deploy the report into report server
Create the SSIS package
Drag your Script task into the package.
You could use the following code snippet to send SSRS report using SSIS.
You should create some of the SSIS variables to store the report and render information.
RenderExtension ==> pdf
RenderFileName ==> Name of the file you want write
RenderFormat ==> PDF
RenderOutputPath==> Location to write the file
SSRSConnection ==>
http://localhost/ReportServer/reportexecution2005.asmx [Location of
your report services]
SSRSFolderName ==> Folder name of the report you deployed
SSRSReportName ==> Name of the report
In the following snippet.
public void Main()
{
var rExtension = Dts.Variables["RenderExtension"].Value.ToString();
var rFileName = Dts.Variables["RenderFileName"].Value.ToString();
var rFormat = Dts.Variables["RenderFormat"].Value.ToString();
var rOutputPath = Dts.Variables["RenderOutputPath"].Value.ToString();
var ssrsConnection = Dts.Variables["SSRSConnection"].Value.ToString();
var ssrsFolderName = Dts.Variables["SSRSFolderName"].Value.ToString();
var ssrsReportName = Dts.Variables["SSRSReportName"].Value.ToString();
ReportExecutionService rs=new ReportExecutionService();
Byte[] results;
string encoding = string.Empty;
string mimetype = string.Empty;
string extension = string.Empty;
Warning[] warnings = null;
string[] streamId = null;
string deviceInfo = null;
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = ssrsConnection;
try
{
var reportpath = string.Format("/{0}/{1}", ssrsFolderName, ssrsReportName);
rs.LoadReport(reportpath, null);
//Adding Parameters
//Commenting the following line Till we test the functionality
ParameterValue[] paramValues = new ParameterValue[4];
ParameterValue paramValue = new ParameterValue();
paramValue.Name = "ReportParamName";
paramValue.Value = "X,Y,Z";
paramValues[0] = paramValue;
rs.SetExecutionParameters(paramValues, "en-US");
results = rs.Render(rFormat, deviceInfo, out extension, out mimetype, out encoding, out warnings, out streamId);
var filewithdatetime = string.Format("{0}_{1}",rFileName,DateTime.Now.ToString("yyyy_MM_dd_hhmmss"));
string path = string.Format(#"{0}\{1}.{2}", rOutputPath, filewithdatetime, rExtension);
MessageBox.Show(path);
using (FileStream stream = File.OpenWrite(path))
{
stream.Write(results, 0, results.Length);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace);
}
Dts.TaskResult = (int)ScriptResults.Success;
}
Hey Guys I have a database with field
Name,Email,Contact,Address,Profile And I have created a excel sheet with
these field & data in it (100 entry).
Now i want to use File-upload Control for browsing these excel sheet & on click of Button Control it automatically fill excel sheet data into database.
So anybody who has a idea kindly share with me. I try over it a lot but doesn't reach to solution. So please kindly share your valuable guidance.
Take a look at the Excel Data Reader project. With this you can very easily dump an Excel file (either older binary format or newer OpenXML format) into a DataSet, at which point you can do whatever you want with the data. Here's some sample code I used as a proof of concept in a previous project:
private static DataSet ImportDataFromExcelFile()
{
DataSet dataFromExcelFile = null;
// Try importing the file as OpenXML
using (var excelFile = File.Open(excelFileName, FileMode.Open, FileAccess.Read))
{
using (var excelReader = ExcelReaderFactory.CreateOpenXmlReader(excelFile))
{
excelReader.IsFirstRowAsColumnNames = true;
dataFromExcelFile = excelReader.AsDataSet();
}
}
if (dataFromExcelFile != null)
return dataFromExcelFile;
// Try importing the file as Excel 97-2003
using (var excelFile = File.Open(excelFileName, FileMode.Open, FileAccess.Read))
{
using (var excelReader = ExcelReaderFactory.CreateBinaryReader(excelFile))
{
excelReader.IsFirstRowAsColumnNames = true;
dataFromExcelFile = excelReader.AsDataSet();
}
}
if (dataFromExcelFile != null)
return dataFromExcelFile;
throw new Exception("Unable to determine format of Excel file.");
}
First it tries to read the Excel file in the more modern format. If that fails, it tries in an older format. If that fails, it gives up and throws an exception.
I have data in XML format. I stored it in varchar datatype column. I have retrieved it by using Linq to sql in visual studio 2010. I got xml format data in string variable. now i need read it as a Xml. I need to take value in particular node.
for example,
<Sale>
<LTV>150</LTV>
<CLTV>350</CLTV>
<DLTV>600</DLTV>
</sale>
I NEED TO TAKE CLTV value.
This code should work for you:
using System.Xml;
...
string xmlStr = "<sale><LTV>150</LTV><CLTV>350</CLTV><DLTV>600</DLTV></sale>";
XmlDocument x = new XmlDocument();
x.LoadXml(xmlStr);
MessageBox.Show(x.GetElementsByTagName("CLTV")[0].InnerText);
var value = XDocument.parse("YOUR_XML_STRING").Root.Element("ELEMENT_NAME").Value;
try
var xml = XElement.Parse("your xml");
//Gives you the value of the CLTV node
xml.Descendants("CLTV").FirstOrDefault().Value;
To change the value
xml.Descendants("CLTV").FirstOrDefault().Value = "1";
//Save to disk
xml.Save({stream or file location});
//Get a string back
xml.ToString();
Descendants will give you a list of XElements that you can enumerate or by doing FirstOrDefault you will get the first one it finds or an empty Element.
I've been building this project as the solo dev for a while, and while I'm comfortable in the front end and middle tier, I don't really think I'm doing the database the way I should be, and the reason why is because I simply don't really know of any other way. The way I'm currently getting data is by testing out queries in my MySQL workbench and copying and pasting the SQL as a string literal into a method that makes a call to the DB, pulls the data and hydrates my objects.
This hasn't really been a problem until recently, when I had to create a monster of a query and it got me thinking that maybe there's a better way to do this. I don't have a formal DAL separated out, so I know there's room for improvement there, but I was curious about what the correct way would be to store SQL strings. I assume there is a tool somewhere built into VS10 where I can manipulate and work with SQL as SQL instead of as a string.
You should be doing this in stored procedures. That will basically format and store your query. You set parameters that are passed in from your code, then read out the results.
Example:
The C# method:
private void SetNote()
{
const string sql = "sp_SelectControllerNoteByID";
using (var conn = MocSystem.GetMocDbConnection())
{
using (var comm = new SqlCommand(sql, conn))
{
comm.CommandType = CommandType.StoredProcedure;
comm.Parameters.Add(new SqlParameter("#ControllerNoteID", ControllerNoteId));
try
{
conn.Open();
using (var rdr = comm.ExecuteReader())
{
while (rdr.Read())
{
CommentText = rdr["NoteText"].ToString();
_commentor = new User(new Guid(rdr["NoteAuthor"].ToString()));
CommentDate = (DateTime)rdr["NoteDate"];
MocRequestId = (int)rdr["MocRequestID"];
}
}
}
catch (Exception ex)
{
HasError = true;
ErrorMessage += "\nThere was a problem building the note: " + ex.Message;
}
}
}
}
The stored procedure on the DBMS (sql server in this example):
ALTER proc [dbo].[sp_SelectControllerNoteByID]
#ControllerNoteID int
AS
SELECT
ControllerNoteID,
NoteText,
NoteDate,
NoteAuthor,
MocRequestID
FROM
ControllerNotes
WHERE
ControllerNoteID = #ControllerNoteID
So here we call the stored procedure which in this case is just a simple select statement, then we read it out into an object via ADO. Now, this way, you can modify your query without recompiling. Unless you add parameters, in which case you'll have to update those in your code as well.
