Allows users to read the schema of a DATASET data type instance, which is stored as a LOB, using the LOB FNC routines.
Syntax
Void FNC_GetDatasetSchemaLob( DATASET_HANDLE datasetHandle, LOB_LOCATOR* schemaLoc, dataset_schema_encoding_t schemaEncoding)
Syntax Elements
- datasetHandle
- A handle to a DATASET type instance that is defined to be an input parameter to an external routine.
- schemaLoc
- A pointer to a LOB_LOCATOR that will be used to read the LOB schema of a DATASET type instance.
- schemaEncoding
- The encoding in which the user would like to retrieve the schema.
Usage Notes
The schema is returned as UNICODE text, encoded in either UTF-8 or UTF-16, depending on the value of the schemaEncoding parameter.
Use FNC_GetDatasetSchemaLob when the schema is stored as a LOB. If FNC_GetDatasetInfo returns schemaLob > 0, you can use FNC_GetDatasetSchemaLob; otherwise, you should use FNC_GetDatasetSchema instead.
