<p class="MsoNormal"><span style="color:#1F497D">I have often told my students with respect to Microsoft “Just because you can doesn’t mean you should”. I reckon we should continue to use queries for calculated fields for the following reasons:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi folks,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> Just looking into Outcome 2 and looking at the 2010 version of MS Access. I hadn’t noticed before, but you can now create a calculated field in the table definitions.
This means that not only does it do the calculation (duh) but stores that value too, so you no longer have to create a query to do that.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Now, I always stress to my cherubs that one of the primary reasons for making a database is to reduce the amount of space the data is going to take up. This new ‘feature’ does
the reverse. Given hard drives are so cheap and our down databases are comparatively quite small, it doesn’t really affect SAC scenarios……… but should we be teaching best practices or “The Way of the Access”? How do others feel about this?<o:p></o:p></span></p>
