Updating a database using coldfusion
To create and reference an upload script, refer to the Cold Fusion HTTP File Upload Handler Script section in the Edit Live!
Within this section, we can add and manage data sources (DSN’s) in Cold Fusion.
and Cold Fusion: CREATE TABLE `articles` ( `article_id` int(11) NOT NULL auto_increment, `article_title` varchar(255) collate utf8_unicode_ci NOT NULL default '', `article_style Element Text` blob NOT NULL, `article_body` blob NOT NULL, PRIMARY KEY (`article_id`) ) DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; To use Edit Live! Each of these pages is explained here and code samples are provided. Start with a standard HTML page containing Edit Live! To see the steps involved in creating this page please see Edit Live! The file displays the chosen article information to allow the user to confirm that they wish to delete the specified article.
The index page of the press release center lists all of the articles currently available in the database. Once confirmation is obtained, the relevant record in the database is deleted using the processing page, To enable the image upload functionality, a new script must be created and then referenced in the configuration file.
You also reduce the possibility of an accidental data operation by a developer.
Whether you need Blobs and Clobs in your application depends on your requirements.
If that one errors, Cold Fusion will continue closing the bad connections and checking out other connections until there are no connections left in the connection pool.
If it actually got that far (meaning every connection in the pool turned out to be bad) then Cold Fusion will then create a NEW db connection and use that one, and it will run the validation query on that too.
(The programming language used with that platform is also commonly called Cold Fusion, though is more accurately known as CFML.) Cold Fusion was originally designed to make it easier to connect simple HTML pages to a database.
If the validation query fails, your page request will never see the error because Cold Fusion will throw away that db connection and get another connection from the db connection pool.
It will then run the validation query for that connection too.
The example sets several variables affecting the appearance and functionality of the applet and loads a basic document into the instance of the applet.
This example demonstrates how to perform the following with Edit Live! Add a heading to the page of "Create a New Article".
