I am trying to create a selection, based on a database query, of all
contour lines of matching elevations, then move the contours to a new
level based on the contour height (500', 1000', etc). The attributes
for the contour lines does not include the elevation, so can not be
used. I have successfully made the SQL query, and have managed to get
all the appropriate contour lines highlighted. But, I can't seem to
get a full selection of the appropriate lines so things can be
changed.
How can I make the SQL query select the appropriate lines, so the
attributes can then be changed? |
