Delete Identical (Data Management)

AllSource 1.0    |

Summary

Deletes records in a feature class or table which have identical values in a list of fields. If the geometry field is selected, feature geometries are compared.

The Find Identical tool can be used to report which records are considered identical without deleting the identical records.

Usage

    Caution:

    This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

  • This tool finds identical records based on input field values, then deletes all but one of the identical records from each set of identical records. The values from multiple fields in the input dataset can be compared. If more than one field is specified, records are matched by the values in the first field, then by the values of the second field, and so on.

  • With feature class or feature layer input, select the field Shape in the Field(s) parameter to compare feature geometries to find identical features by location. XY Tolerance and Z Tolerance parameters are only valid when Shape is selected as one of the input fields.
