Over the past couple of months, I have seen a few esri-geodatabases and they seem to be either a text field with a length of 20 or 30. Is 30 the maximum field length?

Clarification: The answer I'm looking for is if there is a Cityworks-specific constraint on the text field length in the esri geodatabase.

Maybe extension-specific questions should not be on this site or did I ask this question poorly?? – Jay Cummins Jan 13 '11 at 15:53
See… in meta. – Jay Cummins Jan 13 '11 at 16:13

I have tried to find specification information for cityworks dbs before. Extremely hard to find. You might have to find a customer and ask them to find out for you.

I don't even think I've found a good forum for cityworks.

Yes. That is what I did. Twice. Different answers: 30 and 50! But the 50 value came a forwarded email from Cityworks CST. – Jay Cummins Jan 13 '11 at 20:57

According to this, the maximum text field length for a file geodatabase is about 2GB. (Not that I've tried that, of course, but I've seen fields as long as 1024 characters.)

UPDATE: If Cityworks Geodatabase is a personal geodatabase (based on MS Access), then the maximum character length for a Text field is 255. See here (at the very bottom).

So if I specify a FacilityID of 1024 (not that I would actually do that), Cityworks will accept it? I'll update the question and try to clarify the question. – Jay Cummins Jan 13 '11 at 15:47
@Jay Why not just try that to see whether it works? :-) – whuber Mar 6 '11 at 4:42
At the time, we didn't have actually have Cityworks, but had selected Cityworks (govt red-tape at work). We were creating new featureclasses that we knew would be used in Cityworks. I don't work there anymore, but they still don't have Cityworks--red-tape was extra sticky. – Jay Cummins Mar 6 '11 at 11:37
btw, Cityworks says the max field length for a FacilityID field is 50. I mentioned it as a comment and thought someone else would make an answer out of it, but it's been long enough so I'll do it! – Jay Cummins Mar 6 '11 at 11:39

I was forwarded an email from a Cityworks CST stating the max field length for a Cityworks FacilityID field is 50.
