ADO Examples and Best Practices
"You're not reading this book for the jokes -- at least, I hope not."
If you have ever heard Bill Vaughn speak at a conference such as VBITS, you appreciate the significance of those opening words from his latest book, ADO Examples and Best Practices, published by Apress. Bill really is a funny guy, which makes reading this book a pleasure. More importantly, though, he has an intimate knowledge of both Visual Basic and Microsoft's Universal Data Access technology. Add to that his 14+ years of experience at Microsoft (most recently as part of the Microsoft Technical Education team), and you have the makings for a great publication.
The book begins with a comprehensive history of the various ADO versions and points out the "gotcha's" associated with upgrades to newer versions of MDAC. Next, Bill briefly explains how to install and deploy ADO. After this quick introduction, he delves into the meat of this best practices feast.
If you're not familiar with the Connection, Command and Recordset objects of ADO, then you would do well to read up on the ADO object model before embarking on this journey. Remember, this is a book on Best Practices, not an ADO tutorial. Some of the interesting points I marked for reference are:
- Avoid MSDN syntax:
Dim cn As New ADODB.Connection(pg 37)
- Always set ConnectionString property first (pg 15)
- Always use Native Providers as opposed to ODBC provider (pg 26)
- Never reuse Command objects (pg 76)
- Avoid the Refresh method like the plague (pg 88)
- One of 7 deadly ADO sins:
Do Until rs.EOF ...(pg 195)
- Passing Data: Do you really need an ADO recordset?
- Command Ojbect: The biggest benefit to performance
- Tips for working with SQL Stored Proceedures.
- Bill Vaughn's refreshing honesty! (pg 159- box)
- Data Shaping and ADO
- Web-based Solutions
- ADO and the Visual Database Tools
- The source code used in the book
- Utilities to help you be more productive
- Links to other sources of information
I have to admit I am predisposed to books that focus on best practices. I picked this book up as soon as it hit the store shelves. When the angryCoder extended the offer to write a review, I jumped at the chance. I love this book and would recommend it to any and all of my colleagues who develop Web or desktop applications using ADO.
On the other hand, if you're new to ADO, look elsewhere first. This book isn't a tutorial, and it's not an ADO Reference volume. Definitely not for beginners.
