Subject: SQL Count
All,

I have a map layer with a row for each case of a disease.  Using a
spatial join in I got the census tract for each point and now I want a
layer with the frequency by census tract.

I would like to do something like:

select CensusTract, count(*) as CensusCount
into NewLayer
from MyTable
group by censusTract

Is such a thing possible within ArcMap?

thanks ahead of time
deborah

Have a look at Hawth's tools (freeware for ArcGIS).

Won't the "SUmmary Statistics" tool do this? The "Frequency" command
in Workstation Arc/INFO will do it.

The 'Frequency' command is also under the GUI in ArcGIS using
ArcToolbox.  ArcMap -> ArcToolbox -> Analysis Tools -> Statistics ->
Frequency.

I'm not sure why ArcGIS doesn't support full SQL instead of just the
where clause, joins/relates, and separate commands like the one
above.  It seems to me that ArcGIS is missing out on the real power of
a RDMS, which is full SQL support.

Mainly because of its heritage in a non-SQL database, I think. You can
use native database enquiries in Arc Workstation.
