             Summary: Add GEOMETRY_COLUMNS view
                 Key: TEIID-3301
                 URL: https://issues.jboss.org/browse/TEIID-3301
             Project: Teiid
          Issue Type: Feature Request
            Reporter: Tom Arnold
            Assignee: Steven Hawkins


Another OGC Simple Features implementation detail. Basically this is like a specialized version of SYS.COLUMNS, and would be used to support GIS software (like GeoServer).

{code}
CREATE TABLE GEOMETRY_COLUMNS (
  F_TABLE_CATALOG   CHARACTER VARYING NOT NULL,
  F_TABLE_SCHEMA    CHARACTER VARYING NOT NULL,
  F_TABLE_NAME      CHARACTER VARYING NOT NULL,
  F_GEOMETRY_COLUMN CHARACTER VARYING NOT NULL,
  G_TABLE_CATALOG   CHARACTER VARYING NOT NULL,
  G_TABLE_SCHEMA    CHARACTER VARYING NOT NULL,
  G_TABLE_NAME      CHARACTER VARYING NOT NULL,
  STORAGE_TYPE      INTEGER,
  GEOMETRY_TYPE     INTEGER,
  COORD_DIMENSION   INTEGER,
  MAX_PPR           INTEGER,
  SRID              INTEGER NOT NULL
  REFERENCES SPATIAL_REF_SYS,
  CONSTRAINT GC_PK PRIMARY KEY
   (F_TABLE_CATALOG, F_TABLE_SCHEMA, 
    F_TABLE_NAME, F_GEOMETRY_COLUMN)
)
{code}

I think we could implement this by storing SRID & friends as column properties, and then creating a view on SYS.COLUMNS & SYS.PROPERTIES.
