[postgis-users] How to use dimension(geometry) command

[José María Amuedo]

Hi,

I meant dimension(geometry) to know if my consulted data is 2D or 3D.

I found in the oficial documentation that if you use dimension(geometry)
you get 2 for 2D or 3 for 3D data.

Do you know something about this?

Thanks,

José María
