Remove Attribute Index (Data Management)

Summary

Deletes an attribute index from an existing table, feature class, shapefile, or attributed relationship class.

Attribute indexes are used by ArcGIS to quickly locate records that match an attribute query.

Usage

  • This tool accepts shapefiles, geodatabase feature classes, and attribute relationship classes as input.

  • If the Index Name parameter is empty when the Input Table parameter value has been provided, there are no attribute indexes in the dataset.

  • Once an index has been added, it can be deleted and re-added at any point in the lifetime of the feature class or table.

  • For enterprise geodatabase data that is not registered as versioned, you can delete both unique and nonunique indexes on GlobalID fields. However, if you remove the index on a GlobalID field, it is recommended that you re-add an index on the GlobalID field to improve performance for attribute queries on the feature class or table.
