For existing SDE.ST_GEOMETRY polylines that have M-values (aka 'measure values' for linear referencing purposes).
It would be really helpful if ESRI could add a ST_GEOMETRY SQL function that could be used to UPDATE the M-values to the cumulative length of line.
In other words, if we look at the image below, the M-values would be updated so that they're the same as the length of the line at a given vertex.
Could ESRI consider adding a function for that?
I believe it would be the equivalent of Oracle Spatial's REDEFINE_GEOM_SEGMENT function.
