You can store images in a Database to later access them. To do that,
you have to use the following code to get the image from the database.ASP > Tips and Tutorials > Database-relatedOct 10, 2006Drew Gauderman
Providing search capabilities to a db enables users to query on whichever element you target them to. However allowing users to target which portion of the db they would like to query gives extra value. In this example, utilizing our db of US States (state, statename, and capital) the user can search in any of three fields (by dropdown menu input) rather than the application targeting one specific table element. Note: The db only has 50 observations in it, so it is better to search on single or double letter combinations.
Multiple Recordsets - the ability to stuff multiple SQL query results into one Recordset - is an ADO feature that's few developers are aware of. In this article, we are going to take a look on what a Mutliple Recordset is, exactly, and how it can make your development life easier (and your code more efficient). But before we start examining Multiple Recordsets, let's look at a common task in ASP and how it is handled without using Multiple Recordsets.
It?s hard to imagine what the creators of ADO.NET were thinking as they were designing it.? It has been challenge enough just understanding and mastering all of the many objects and their capabilities.? Just think, to physically access a column of data you have to now maneuver through at least five objects instead of two in ADO.?
As part of my effort to learn ADO.NET, I decided to first determine how to reproduce the basic functionality that I had in ADO, especially with the Recordset.? That is where I discovered the new and many uses of the DataView class (although I prefer the term object to class).?
The power of Active Server Pages comes through when we tie databases to our web sites. To connect to a database, ASP uses what is called ActiveX Data Objects, or ADO for short. ADO comes with ASP, and can be used easily from your ASP pages.
In this tutorial we will show you how to connect to our Access database called 'examples.mdb' and retrieve all the records from the table 'cars'.
At first we must create an instance of the connection object and feed it the location of the database we wish to connect to and the driver that we intend to use. For these purposes we will use a connection string. You can choose an ODBC or an OLEDB connection string. We will use OLEDB for our example as it's faster and more stable. Next, we should open the connection to the database:
This article shows how to use the refresh method of the ADO Parameters collection to interrogate a stored procedure. You may already have experience using ADOX or SQL-DMO to accomplish this, but please keep in mind that the method displayed here is meant to be simple enough that anyone with ADO experience can use it. (ADOX and SQL-DMO will be addressed later.)
