Name

ST_YSize — Returns the Y size of a 2D or 3D bounding box or a geometry.

Synopsis

float ST_YSize(box3d aGeomorBox2DorBox3D);

Description

Returns the Y size of a 2D or 3D bounding box or a geometry, computed as ST_YMax(aGeomorBox2DorBox3D) - ST_YMin(aGeomorBox2DorBox3D).

[Note]

Although this function is only defined for box3d, it also works for box2d and geometry values due to automatic casting. However it will not accept a geometry or box2d text representation, since those do not auto-cast.

This function supports 3d and will not drop the z-index.

This method supports Circular Strings and Curves.
