ArcMap & Enterprise 10.7.1 — Oracle 18c SDE.ST_GEOMETRY — SQL Developer 18:
I have an SDE.ST_GEOMETRY polyline FC that is M-enabled:
In an SQL client like SQL Developer, I can query for the M-value of the endpoint of the line:
select sde.st_m(sde.st_endpoint(shape)) from my_fc
The result of that query is -Infinity. I didn't know that was possible and I wouldn't have thought to account for it when querying for possible values.
Is that behavior expected from ST_GEOMETRY functions? If anything, I would have expected the value to be Null, not -Infinity.
