In this tutorial you are going to learn everything in detail step by step you'll ever want to know about inserting binary data ( images, zip files etc ) into database. This is actually first of the three articles I am going to write on manipulating binary data in the database. After this article you'll be able to upload binary data into database, then in second article you'll learn to get this data out of database and show it as you like and finally in the third article I'll explain uploading files. All of this is going to be plain ASP ( VBScript ) and nothing else, so stay tuned

But why? I read Part I and I was able to implement a simple database program very easily. Why would I need to learn anything more?
You might have implemented some database program.. but I am sure it would be a very simple one. You may even be able to implement a good database program without Joins. But you wouldn't be using the features of SQL that let you do the same work much easily. Without Joins, you may manage SQL.. but with Joins you could do things very easily

To database or not to database? What to do with uploaded files on server-side? This article contains performance tests of several store-file methods in server-side ASP.
We test store files to disk, to MDB file using ADO recordset, to MS SQL 2000 using ADO recordset and to MS SQL 2000 using SQL UPDATETEXT command

In this chapter, we'll be discussing how to get at data from your C# programs using ADO.NET. Over the course of this chapter, we'll be covering the following areas:

Connecting to the database - how to utilize the new SqlConnection and OleDbConnection classes to connect to and disconnect from the database. Connections utilize the same form of connection strings as did OLEDB providers (and therefore ADO), and these are briefly discussed. We then go through a set of best practices for utilizing database connections, and show how to ensure that a connection is closed after use, which is one of the sources of poor application performance.
Executing Commands - ADO.NET has the concept of a command object, which may execute SQL directly, or may issue a stored procedure with return values. The various options on command objects are discussed in depth, with examples to show how commands can be used for each of the options presented by the Sql and OleDB classes.
Stored Procedures - How to call stored procedures using command objects, and how the results of those stored procedures may be integrated back into the data cached on the client.
The ADO.NET object model - this is significantly different from the objects available with ADO, and the DataSet, DataTable, DataRow, and DataColumn classes are all discussed. A DataSet can also include relationships between tables, and also constraints. These issues are also discussed.
Using XML and XML Schemas - ADO.NET is built upon an XML framework, so we'll examine how some of the support for XML has been added to the data classes.
We'll also present a guide to the naming conventions that preside in the world of ADO.NET and explain some of the reasoning behind them. First, though, let's take a brief tour of ADO.NET and see what's on offer

If you have an SQL database set up with your web host, a useful tip to know is how to connect to your SQL database via Enterprise Manager. The advantage of knowing

You can use the "Compact and Repair" function in Access from ASP code. The following code is an example of how this can be done. Note that when you decide to "Compact and Repair" your Access database, some autonumbers can be changed. Access makes all autonumbers consecutive.
This code uses one database, but I'm sure the code can easily be changed so that the listbox displays, for example, all the databases in one folder

This article offers an analysis of Structured Query Language (SQL) and presents techniques that can be used in building SQL statements. People tend to think of SQL as a programming language, but in reality, SQL is a Set language. One could say SQL is Set Theory or Relational Algebra; these terms are interchangeable. Some people think of this in terms of Venn diagrams or DeMorgan's Law. Although those can be quite complicated, the basic forms are not difficult to understand. The cases presented here are intended for certain circumstances, but they can be applied to many situations. Each article in this four-part series will address one case.

Several State and Federal contracts that I have worked on in the past have wanted to keep track of all changes to a particular record, such as who modified the record, what kind of modification took place, and when the record modification occurred. I decided to solve this problem with triggers because I wanted to capture every action that occurred on a particular table. For those unfamiliar with triggers, a trigger is a database-event that fires when a particular action occurs. For example, an INSERT trigger would fire when a particular database table has a record inserted. For a more in-depth examination of triggers, be sure to read

Shuffling a recordset so that it can be displayed in random order is very useful when programming dynamic Web pages. A database table containing a list of supported vendors or links to advertisers may need to be displayed in a different order each time so that none complain about always being last on the list.
