How to add a geometry column to a table?
Alter the table to add a geometry (SDO_GEOMETRY) column. Update the table to populate the SDO_GEOMETRY objects using existing location-related data values. Update the spatial metadata (USER_SDO_GEOM_METADATA). Create the spatial index on the table. — Original table without a spatial geometry column.
How is an SDO geometry table created in ArcGIS?
A table with an SDO_GEOMETRY column is created. A spatial index is created on the SDO_GEOMETRY column. A record is added to the Oracle Spatial metadata view. A coordinate dimension is specified. The SDO_GEOMETRY column is populated. An additional column is added to the business table to store CAD and annotation properties.
How to insert point geometry into a feature?
In the example below, point geometry is inserted into a feature class from an existing database table. Create an empty point feature class in ArcMap using one of the following spatial types.
How to spatially enable a table in Oracle?
If you have a regular Oracle table without an SDO_GEOMETRY column, but containing location-related information (such as latitude/longitude values for points), you can spatially enable the table by adding an SDO_GEOMETRY column and using existing (and future) location-related information in records to populate the SDO_GEOMETRY column values.
Why is geometry validation not included in spatially enabling a table?
(SDO_GEOMETRY objects have longitude first, then latitude for points.) Geometry validation is not included in the example because validation is not relevant for points. However, if you spatially enable a table with other types of geometries, you should validate all initial and added geometries.
How to migrate geometry columns from Oracle to SQL?
The steps to achieve a successful migration are: 1. Select the object’s node in the connection tree such that its Properties Metadata dialog appears; select all columns that are to be migrated. 2. Create a SELECT statement including all columns that are for migration; 3. Execute the statement using F9 to get a rowset (table).
