LOGICAL AttachDataSource (handle)
Purpose: Attaches the Data-Source to the ProDataset buffer object handle
Notes:

Parameters:
phProDatasetBuffer HANDLE
The handle of the ProDataset buffer
Returns LOGICAL
Logical return value of the ATTACH-DATA-SOURCE method
Top

LOGICAL AttachDataSource (handle, character)
Purpose: Returns the handle of the data-source object
Notes: The implementation is required to remove and white space characters
from pcPairsList that might have been inserted to improve readability
but are not supported by the DATA-SOURCE

Parameters:
phProDatasetBuffer HANDLE
The handle of the ProDataset buffer
pcPairsList CHARACTER
pairs-list An optional character expression that evaluates to a comma-delimited list of field name pairs that specify a mapping between different field names in the data-source object buffer and the ProDataSet temp-table buffer
Returns LOGICAL
Logical return value of the ATTACH-DATA-SOURCE method

from pcPairsList that might have been inserted to improve readability
but are not supported by the DATA-SOURCE

Parameters:
phProDatasetBuffer HANDLE
The handle of the ProDataset buffer
pcPairsList CHARACTER
pairs-list An optional character expression that evaluates to a comma-delimited list of field name pairs that specify a mapping between different field names in the data-source object buffer and the ProDataSet temp-table buffer
pcExceptList CHARACTER
An optional character expression that evaluates to a comma-separated list of fields in the ProDataSet object buffer that will not be populated with data from the data source
Returns LOGICAL
Logical return value of the ATTACH-DATA-SOURCE method

Parameters:
phProDatasetBuffer HANDLE
The handle of the ProDataset buffer
pcPairsList CHARACTER
pairs-list An optional character expression that evaluates to a comma-delimited list of field name pairs that specify a mapping between different field names in the data-source object buffer and the ProDataSet temp-table buffer
pcExceptList CHARACTER
An optional character expression that evaluates to a comma-separated list of fields in the ProDataSet object buffer that will not be populated with data from the data source
pcIncludeList CHARACTER
An optional character expression that evaluates to a comma-separated list of fields to include in the ProDataSet object buffer, as an alternative to specifying fields to exclude in except-fields.
Returns LOGICAL
Logical return value of the ATTACH-DATA-SOURCE method

Notes:

Parameters:
pcBufferName CHARACTER
The name of the buffer
Returns HANDLE
The handle of the data-source object
Top

HANDLE GetBufferHandle (integer)
Purpose: Returns the handle of a source buffer
Notes:

Parameters:
piIndex INTEGER
The index of the buffer
Returns HANDLE
The handle of the data-source object
Top

Initialize ()
Purpose: Initializes the DATA-SOURCE object handle and supporting objects
Notes:

Top

CHARACTER SourceColumn (character)
Purpose: Returns the database field name matching a temp-table field name
contained in a consumers query string (query string vs. temp-table
definition)
Notes: To be used in the DataAccess:SourceColumn method

Parameters:
pcColumn CHARACTER
The temp table column name to return the source (database table) field name for
Returns CHARACTER
The database field name mapped to the passed in temp-table field
Top

CHARACTER SourceDefaultQuery ()
Purpose: Returns the default query string (USING OF) that can be used for the
SourceDefaultQuery method of the DataAccess class
Notes: Can not be used, when the buffers cannot be joined using OF

Returns CHARACTER
The query string for the source default query
Top

CHARACTER SourceDefaultQuery (logical)
Purpose: Returns the default query string (optionally resolving the OF) that can be used for the
SourceDefaultQuery method of the DataAccess class
Notes: Can not be used, when the buffers cannot be joined using OF

Parameters:
plResolveOf LOGICAL
Logical value indicating if the OF relation shoudl be resolved into a WHERE clause
Returns CHARACTER
The query string for the source default query
