Oracle Spatial/Locator Servers

JMap Server can connect to Oracle Spatial or Locator databases to extract spatial data and attributes to be used as a spatial data source. The only special requirement is the presence of a numeric column with unique integer values to be used as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.

The connection to the database must already be configured. See Creating Databases for more information.

Parameters

Database

Select the Oracle database to read the data from. It must already be configured in JMap Admin.

SQL query

Enter the SQL query used to extract geometries and attributes from the database.

Geometry table

Select the physical table that effectively contains the geometries. Pressing Load will retrieve the list of fields returned by the query. This is necessary for the rest of the configuration.

Geometry field

Select the field that contains the geometries.

Id field

Select a field that contains unique identifiers. Only integer fields are listed.

Creation time field

This parameter is optional. If you want this data source to be editable by JMap, this field will show the creation date of each object. If no field is selected, the data can still be edited, but this information will not be maintained.

Modification date field

This parameter is optional. If you want this data source to be editable by JMap, this field will contain the date each object was last modified. If no field is selected, the data can still be edited, but this information will not be maintained.

Author field

This parameter is optional. If you want this data source to be editable by JMap, this field will either contain the name of the user who created each object or the name of the user who made the last change. If no field is selected, the data can still be edited, but this information will not be maintained.
