QGIS algorithm Execute SQL

Description

QGIS Algorithm provided by GDAL Execute SQL (gdal:executesql)

Usage

gdal_executesql(
  INPUT = qgisprocess::qgis_default_value(),
  SQL = qgisprocess::qgis_default_value(),
  DIALECT = qgisprocess::qgis_default_value(),
  OPTIONS = qgisprocess::qgis_default_value(),
  OUTPUT = qgisprocess::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
SQL	string - SQL expression. String value.
DIALECT	enum of ("None", "OGR SQL", "SQLite") - SQL dialect. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
OPTIONS	string - Additional creation options. String value.
OUTPUT	vectorDestination - SQL result. Path for new vector layer.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output	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.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
