Formerly it was:
SELECT mydatefield as DateEntered
then
<cfgridcolumn
name="mydatefield"
display="yes"
header="Date"
mask="EEE DD-MMM-YY H:NN A">
Which sucked and continued to show me whatever it wanted, rather than the "mask" attributes the cfdocs had. So I changed it to this:
SELECT CONVERT(VARCHAR(11), mydatefield, 106) AS DateEntered
then
<cfgridcolumn
name="mydatefield"
display="yes"
header="Date">
And the resulting output looks like this:
22 Jun 2008
You can google for SQL DATE FORMAT or something like that and see the whole huge list of numbers (mine 106, above) that will format dates differently.
