In this post, you’ll learn more about the Oracle ErrorORA-54526: multi or composite geometry must be decomposed before extraction with the details on why you receive this error and the possible solution to fix it.

Oracle Error Description

ORA-54526: multi or composite geometry must be decomposed before extraction

Reason for the Error ORA-54526: multi or composite geometry must be decomposed before extraction

The extraction could not be performed because the multi or composite geometry must first be decomposed into simple geometries (with or without inner geometries). The multi or composite geometry had a gtype of GTYPE_MULTISOLID, GTYPE_MULTISURFACE, GTYPE_MULTICURVE, GTYPE_MULTIPOINT, or GTYPE_COLLECTION, or the geometry was a line string.
