<div class="content wysiwyg-content">
I have the following t-sql...<br />
<br />
SUM(DATEDIFF(MINUTE, CONVERT(datetime, tblProduction.startDate, 101) + ' ' + CONVERT(datetime, tblstarttime.time, 108), CONVERT(datetime, tblProduction.endDate, 101) + ' ' + <br />
CONVERT(datetime, tblendtime.time, 108)) / 60) AS totalhours<br />
<br />
It calculates the correct # of minutes, but when I /60 to get the hours, it rounds down.<br />
<br />
How should I update this so when 30 minutes is calculated, I get 0.5 hours etc.<br />
