[postgis-users] Problems to transform LineStringZM to MultiLineStringZM

[José María]

Hello!

I get a error when I tried to transform LineStringZM to MultiLinestringZM;

*alter table elevacion_89 alter column the_geom type
geometry(MULTILINESTRING, 25830) using St_Multi(the_geom);*
*
*
The error I get it is:

*ERROR: Geometry has Z dimension but column does not*
*SQL state: 22023*
*
*
Any ideas??

Thanks,

Jose
