27 SDO_OLS Package (OpenLS)

The MDSYS.SDO_OLS package contains subprograms for Spatial OpenLS support.

To use the subprograms in this chapter, you must understand the conceptual and usage information about OpenLS in Chapter 14.

Table 27-1 lists the OpenLS subprograms.

Table 27-1 Subprograms for OpenLS Support

Subprogram Description

SDO_OLS.MakeOpenLSClobRequest

Submits an OpenLS request using a CLOB object, and returns the result as a CLOB object.

SDO_OLS.MakeOpenLSRequest

Submits an OpenLS request using an XMLType object, and returns the result as an XMLType object.


The rest of this chapter provides reference information on the subprograms, listed in alphabetical order.


SDO_OLS.MakeOpenLSClobRequest

Format

SDO_OLS.MakeOpenLSClobRequest(
