Support for converting geo column to string #785

Open anirudh-here-com opened 1 year ago

anirudh-here-com commented 1 year ago

Something like ST_AsText function which will return a string representation of a geo column

FYI, https://github.com/heavyai/heavydb-internal/pull/7315 introduces ST_AsText and ST_AsBinary. So, the issue should be resolved in the next heavydb release.

Thanks for the reply!

For some reason I’m unable to access the link.. Which brings another question, are we gonna get this in the open source heavy db repo? We're using the heavydb only without rendering engine🙂

Hi,

Yes you can't see the URL, because it's of our internal repository, and this PR isn't landed yet into any release of the product, nor the OS version you are using.

I'll come back in this thread when the function will be available in a release; it'0s likely to be released in FREE/EE and the in OS.

A little crazy idea. With a copy command you can export a csv file containing the WTKs and re-read them in the db using the CSV as source.

What are you going to use those WKTs?

I want to access geo columns through select_ipc_gpu(arrow transfer) for some downstream processing. The queries will be in high frequency
