java.lang.Object

DropColumnGenerator

liquibase.ext.spatial.sqlgenerator.DropGeometryColumnGeneratorGeoDB

public class DropGeometryColumnGeneratorGeoDB
extends DropColumnGenerator

DropGeometryColumnGeneratorGeoDB is a DropColumnGenerator that specializes in GeoDB. If there exists an index on the column, DropSpatialIndex is invoked first. If the column to be dropped is the geometry column, the DropGeometryColumn procedure is invoked instead of performing the typical ALTER TABLE statement. Otherwise, the next SQL generator in the chain is invoked to handle the request.
