Registering a third-party table containing a spatial column

Use the ArcSDE administration command sdelayer with the register operation to register a spatial table as a feature class.

The register operation allows you to create a feature class from a DBMS table that contains a spatial column defined as a user-defined data type. To date, six different implementations of DBMS spatial data types are supported in ArcSDE geodatabases: Oracle Spatial geometry type (SDO_Geometry), Informix Spatial DataBlade (ST_Geometry), DB2 Spatial Extender (ST_Geometry), spatial type for Oracle (ST_Geometry), spatial type for PostgreSQL (ST_Geometry), PostGIS for PostgreSQL (Geometry), Geometry for SQL Server (Geometry), and Geography for SQL Server (Geography). Tables created with one of these spatial data types and populated using the DBMS SQL interface or some other third-party interface can be added to an ArcSDE geodatabase by registering the existing tables as feature classes.

To register third-party spatial tables, the following prerequisites must be met:

For syntax and examples using the sdelayer command, see the ArcSDE Administration Command reference included with the ArcSDE component of ArcGIS Server Enterprise.


The autoregistration functionality for SDO_Geometry present in previous ArcSDE versions has been deprecated.

  1. At an MS-DOS (Windows) or shell (UNIX or Linux) prompt, execute the sdelayer command with the register operation.

    sdelayer -o register -l samplepts,geom -e p+ -C ptid,SDE -t
    PG_GEOMETRY -g RTREE -E -76.74381615680447,34.59132803608262,-74.56368991230103,36.18919425895801
    -i sde:postgresql:myserver -s myserver -D bigdb -u editor -p open.up

    If you register the feature identifier column as user-maintained (-C id,USER) instead of SDE maintained as shown in the example, and you subsequently register the feature class with the geodatabase, ArcGIS adds an additional feature identifier column, ObjectID. ArcGIS maintains the values of this column. If the table contains a large number of records, adding this additional ObjectID column may take some time.
