Getting coordinate vertices of a polyline in QGIS

Question

How can I get the (x,y) coordinates of the vertices of a polyline in QGIS?

I do not find the function in the field-calculator

I can find the coordinates for each point, but I am not able to highlight it only for the first and the last point for each polyline. I would like to link those value for each polyline

Convert the line to points, then use the tool add geometry columns. — Erik, Jul 16 '21 at 07:55

@Taras that might be, just if it is for interest to the OP (not a new user) — Babel, Jul 16 '21 at 08:29
What are you looking for exactly? Get the X and Y, get the geometry, style the line showing the start/end points, label the points, else? — JGH, Jul 16 '21 at 13:08

The solution is to use for all the items the function:

$y_at (0) and $x_at (0) (coordinates of the first point of the polyline)
$y_at (-1) and $x_at (-1) (coordinates of the last point of the polyline)
