QGIS Algorithm provided by QGIS (native c++) Retain fields (native:retainfields). Retains selected fields from a vector layer. This algorithm takes a vector layer and generates a new one that retains only the selected fields. All other fields will be dropped.
qgis_retainfields(
INPUT = qgisprocess:::qgis_default_value(),
FIELDS = qgisprocess:::qgis_default_value(),
OUTPUT = qgisprocess:::qgis_default_value(),
...,
.complete_output = .complete_output_option(),
.quiet = .quiet_option(),
.messages = .message_option()
)source - Input layer. Path to a vector layer.
field - Fields to retain. The name of an existing field. ; delimited list of existing field names.
sink - Retained fields. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
