select count(*) from dum where the_geom is null gives a result of 0
select count(the_geom) from dum gives a result is 1676, which is the total number of rows in the table
This is consistent with my previous description. The apparently blank the_geom fields apparently have some data, but the data doesn't display. This seems odd, and makes it difficult (impossible for me, so far) to identify the blank fields.
(Sorry this seems to be a duplicate. I couldn't figure out how to reply to a message in a thread and assumed the mail program would figure it out. It didn't. Just for the heck of it I clicked on the name of the person I was replying to with the idea that I'd send a message directly to him, and a mail window opened to send a message to the list. Who knew? I searched, and couldn't find any information explaining this.)
