Hi All,
I'm having trouble executing an Attribute Query when I base the query
(qitem) on the "filename" field in my shapefile. I can choose any other
field and supply the appropriate qstring and everything works fine but
when I use the filename field I get a "no matching records" found error.
The text in the long string in the address bar of the browser IS
complete and DOES match the value in the shapefile. Perhaps the text
values in the shapefile field are too long for MapServer or special
characters like the "." or "-" are causing a problem ? Can anyone
confirm or deny either of my theories about this or point to any other
possibilities ?
The qstring is ...
p016r032_09-09-1986_lt5_doc.img
The qitem is "filename" and it is a text field.
The entire query string in the address bar is ...
http://localhost/cgi-bin/mapserv.exe?qlayer=landsat_4&myitem=landsat_4%2Cfilename&qstring=p016r032_09-09-1986_lt5_doc.img&map=C%3A%5Cms4w%5CApache%5Chtdocs%5Cimg_browser%5Cimg_browser.map&program=%2Fcgi-bin%2Fmapserv&mode=itemnquery&qitem=filename
The error is ...
msQueryByAttributes(): Search returned no results. No matching record(s)
found.
