Load Data

サマリー

Moves features from one schema to another by loading data from a source to a target workspace. Data mapping rules described in a cross-reference database are applied during the load.

Data that matches the schema defined in the cross-reference database for the source is appended to the target workspace. The cross-reference database contains a DatasetMapping table that lists pairs of source and target dataset names. Each source and target name pair can have a WHERE clause and a subtype. The WHERE clause defines a subset of features in the source to append to the target. Subtype identifies a subtype in the target feature class into which features are loaded.

使用法

• The cross-reference database has other tables that affect load data functionality. These tables enable the following operations:

  • Map fields between data sources.
  • Override values from source to target.
  • Specify different source and target schema owners for enterprise geodatabases.

• Use the Dataset Mapping Definitions parameter to specify which feature classes, shapefiles, or coverages to load from the input source to the target workspace. The list of sources and targets comes from the DatasetMapping table in the cross-reference database.

• You can only set WHERE clauses and subtypes in the DatasetMapping table in the cross-reference database. You cannot set these in the Dataset Mapping Definitions parameter.

• The ID value used in the Dataset Mapping Definitions parameter must refer to an existing row ID in the DatasetMapping table in the cross-reference database. The row in the DatasetMapping table contains the name of the source and target datasets.

• This tool returns the warning Source dataset [dataset name] not found or is inaccessible for each source feature class listed in the cross-reference database that is not found in the input sources workspace.

• This tool returns the warning Target dataset [dataset name] not found or is inaccessible for each target feature class listed in the cross-reference database that is not found in the target workspace.

LoadData(in_cross_reference, in_sources, in_target, {in_dataset_map_defs}, {row_level_errors})

パラメーター	説明	データ タイプ
in_cross_reference	The path to a cross-reference database.	Workspace
in_sources [in_sources,...]	A list of workspaces that contain the source features to load into the target workspace.	Workspace
in_target	The target workspace that contains the schema referenced in the cross-reference database. Source features are loaded into this workspace.	Workspace
in_dataset_map_defs [in_dataset_map_defs,...] (オプション)	The source to target feature class mapping list. The format of this string is id | SourceDataset | TargetDataset | WhereClause | Subtype.	String
row_level_errors (オプション)	Indicates if the tool will log errors that occur while inserting new rows into feature classes and tables in the in_target parameter. ROW_LEVEL_ERROR_LOGGING —Log errors that occur during individual row-level inserts. This is the default. NO_ROW_LEVEL_ERROR_LOGGING —Do not log errors that occur during individual row-level inserts.	Boolean
