When to use 'reader' versus a datatable, table adaptor?

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :ASP.Net

I'm making the leap from using all the 'wizards' that are built into VS, and have been doing more with code-behinds.  But, I'm curious as to when/why I should use a reader, versus a databable, table adaptor to "manage" the data returned from a stored procedure.  Typically, the data is to be displayed on a webpage, and not written back to the database.  What's the difference?  When should I use one over another?

Help creating HTML table from dataTable when every nth dataTable row = 1 html table row... C#

Hello, Im trying to create an html table from data that is in a dataTable but Im having trouble coming up with the right logic. Every 3 rows in the dataTable needs to be 1 row in the html table.  Ive tried using foreach through the datatable with a modulus to determin every third dataTable row but i still run into snags because i am building the table using objects rather than using concatenated strings..(example TableRow tr = new TableRow  etc...). I cant add the cells to the rows when the row is only created in an if statement etc. Can someone post a good example in c# of how they would achieve this. The amount of data in the dataTable could change from time to time so the code cant rely on a pre determined size, unless you just need the total rows and columns, that can be dtermined when the dataTable is filled from the sqlDataReader. <table><tr><td>dataTable row 1 values</td><td>ataTable row 2 values</td><td>dataTable row 3 values</td></tr> <tr><td>dataTable row 4 values</td><td>dataTable row 5 values</td><td>dataTable row 6 values</td></tr>   Any help and example would be great. Ive been able to do similar tables in other apps but thats only when I use concatenated text strings to build the html table. Im trying to stay away from that this time

Import DataTable into SQL Table

I'm trying to parse a text file into a sql table.  I have the code to parse the file and display it in a datatable but for the life of me I can't figure out how to import it into a sql table.  All my previous experience has been with csv files and with schema.ini files.  This is new to me.  This is what the code to read the text file and display it in a datagridview: Dim dtTest As DataTable Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load dtTest = New DataTable DataGridView1.DataSource = dtTest.DefaultView End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim filename As String = "C:\Price.txt" Dim lstValues As New List(Of String) Try Using sr As StreamReader = New StreamReader(filename) While Not sr.EndOfStream Dim splits As String() splits = sr.ReadLine.Split(","c) dtTest.Columns.Add(splits(1), GetType(String)) lstValues.Add(splits(2)) End While End Using Catch ex As Exception End Try dtTest.Rows.Add(lstValues.ToArray) End Sub This is what the data in the text file looks like: DD/MM/YYYY HH:MM:SS,LAU4AB,245.35 DD/MM/YYYY HH:MM:SS,ROC06,123.45 DD/MM/YYYY HH:MM:SS,GRE033,87.5 The second item "LAU4AB is the column header for the first

Table-valued parameter and DataTable from ADO.NET


I'm going to use TVP:s to enhance performance in my c# .net fw 4 application which uses stored procs in SQL Server 2008. My first test was very successful and I inserted a batch of rows from by using a TVP in a stored proc. So far so good. Now to my question: when looking for the performance profit with SQL Profiler I saw it was really fast, but the generated sql-code made me a little bit confused. My "table" (DataTable class) from the .net-app was "retabled" like this in sql:

declare @table MyTvpType;

insert @table values (1, 2, 3...); ... x number of times

exec MyProc @table;

This was quite surprising, but when examining my .net code, I think there should be som way to "import" my MyTvpType into .net code, and avoid the extra delaration and inserts done as it is now. I'm using this code in .net:

out of memory loading datatable from large oracle table


I've created a winform c# application that connects to an oracle database and loads a datatable with all the data in the oracle table then exports it out to a delimited file, which will then get imported to a local mysql database.  This works just fine when the oracle table isn't so large.  However I keep getting an out of memory exception when I populate my datatable with a large oracle table.  I can't manually export data from oracle then manually load to mysql because this has to be seamless to the user.  I'm having difficulties grasping how to solve this problem.  Is there a better solution then what I have to get from oracle to mysql?

Export Visio Database Table Names to Excel

If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel. You might want to do this to map logical ERD entities to physical data model tables, track project status by entity, or track overlap between database versions.

Using jQuery to Filter Table Rows

The project is using the .net GridView control, so I had limited control over the output HTML code. Still, I think this code can work for most tables. One thing to notice: you should use the class "filterable" on your table or on one of its parents for the code to work.
First, we need a text box:

RadioButton Groups, Table Rows And NamingContainers in asp.net

The RadioButtonList. Very handy for inviting users to select just one item from a list although because of the screen real estate it takes up, used less and less in favour of the DropDownList. In plain HTML, the browser knows to enforce the unique selected value amongst a list of radio buttons because they all have the same value for their name attributes.

RadioButton Groups, Table Rows And NamingContainers

(In which AJAX-enhanced CheckBoxes become more useful than RadioButtons but inheritance saves the day, and a simple RadioButton-derived control establishes the purpose of a control's naming container)

Building a 3-Tier App with Silverlight 3, .NET RIA Services, and Azure Table Storage

Silverlight 3, .NET RIA Services, and Windows Azure Services Platform makes a 3-tier Cloud application easier to build: Silverlight 3 as presentation tier, .NET RIA services as the business logic and data access tier, and Windows Azure Table as the data storage tier. The sample application in this article demonstrates the architecture with a simple Survey application with all these technologies working together from Windows Azure.

Temporary tables in SQL Server vs. table variables

When writing T-SQL code, you often need a table in which to store data temporarily when it comes time to execute that code. You have four table options: normal tables, local temporary tables, global temporary tables and table variables. I'll discuss the differences between using temporary tables in SQL Server versus table variables.

How to bind GridView and DropDownList controls using DataTable object

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

DataTable - Load from IDataReader - CreateDataReader - ReadXml WriteXml - Free ADO.NET Tutorials

The DataTable in ADO.NET 2.0 has been seriously beefed up and I absolutely love it. Not everything we consume deals with multiple resultsets and requires the ever popular DataSet. With the cool new features in the ADO.NET 2.0 DataTable, we can get many of the cool features in the DataSet without all the extra baggage and memory footprint particular to multiple resultsets.
