Hi,
my humble suggestion is inline.
I have done WMS Time successfully for PostGIS.
Den 14.10.2011 13:55, skrev Katharina Sambs:
Hi list,
I would like to visualize spatial *mySQL* data through a wms-time
service.
*It is possible to visualize the data without the time parameters.*
But as soon as I add the following parameters to the mapfile, my
result contains only a white picture:
LAYER
....
METADATA
....
WMS_TIMEEXTENT "2010-01-10T00:00:00Z"
WMS_TIMEITEM "column_name"
WMS_TIMEDEFAULT "2010-01-10T00:00:00Z"
There is no error message.
*The same request works fine, while I use a shapefile as data source.*
My second question:
Shouldn't be there a 'where'-clause in the database selection, which
contain the time parameter?
I don't think so,
Or works the wms-time like a Filter, which always ask all data from
the database.
Only in the second step, the data is filtered for the desired time?
This filter should be added by Mapserver automagically when you have
WMS_TIME* in METADATA field.
Did anyone has an idea?
You extent should maybe be more "wide".
From http://mapserver.org/ogc/wms_time.html
/value/ - a single value. This is not directly supported in MapServer
but there is an easy workwound by specifying the same value as min and max.
I have always used extents similar to the example in the docs:
"wms_timeextent" "2004-01-01/2004-02-01"
If this is not helping, you should attach (important parts of) mapfile
and URL request.
kind regards

The type of the time data in the mySQL database is "DATETIME".
