![]() Instead, use the tool dialog box browse button to browse to the full paths of each of the Input Datasets values. You can't use multiple input layers with the same name in this tool. If a layer has a selection, only the selected records (features or table rows) will be used. Map layers can be used as Input Datasets parameter values. This tool does not perform edge matching no adjustment to the geometry of features will be made. If the spatial references of an input and target feature class do not match, the features in the input feature class will be projected to the coordinate system used by the target feature class. Geometry will be updated if the Update Geometry parameter is checked. For records with matching field values, any fields in the target record will be updated with values from fields with the same name in the input record. Use the Matching Fields for Update parameter to specify the fields from the input dataset to match to the fields in the target dataset. You can use this tool to insert new records and update existing records in a target dataset in the same operation (equivalent to an UPSERT database operation). ![]() If an input dataset contains fields that do not match fields in the target dataset, that input dataset will be omitted.īecause the data of the input datasets is written to an existing target dataset that has a predefined schema, you can't use the Field Map parameter to add or remove fields from the target dataset. If the Field Matching Type parameter is set to Skip and warn if schema does not match, the schema of the input datasets must match that of the target dataset for features to be appended. Fields in the target dataset that are not mapped to fields from the input datasets will contain null values. Fields from the input datasets that do not match the fields of the target dataset will not be mapped to the target dataset unless the mapping is set in the Field Map parameter. If the Field Matching Type parameter is set to Use the field map to reconcile field differences, the schema does not need to match. If the Field Matching Type parameter is set to Input fields must match target fields, the schema of the input datasets must match that of the target dataset to append features. To combine, or planarize, feature geometries, use the Union tool. All features from both the input feature class and the target feature class will remain intact after the append, even if the features overlap. This tool will not planarize features when they are added to the target dataset. Learn more about mapping fields in scripts Do not perform standard deviation on a single input because values cannot be divided by zero, so standard deviation is not a valid option for single inputs.You can specify the start and end positions of text fields using the format option.To use a space, ensure that the pointer is at the start of the input box and press the Spacebar once. When using the Join merge rule, you can specify a delimiter such as a space, comma, period, dash, and so on.The available merge rules are first, last, join, sum, mean, median, mode, minimum, maximum, standard deviation, and count. ![]() To manage the fields in the output dataset and the contents of those fields, use the Field Map parameter. The Field Map parameter can only be used if Use the Field Map to reconcile schema differences is specified for the Schema Type parameter. You can use the Field Map parameter to control how the attribute information from the input dataset fields is transferred to the target dataset. For example, several tables can be appended to an existing table, or several rasters can be appended to an existing raster dataset, but a line feature class cannot be appended to a point feature class. ![]() ![]() This tool can append point, line, or polygon feature classes, tables, rasters, annotation feature classes, or dimension feature classes to an existing dataset of the same type. Use this tool to add new features or other data from multiple datasets to an existing dataset. ![]()
