Truncate Table


Removes all rows from a database table or feature class using truncate procedures in the database.



    If a selection is applied to a layer or table view, the selection will be ignored—all records will be truncated.

  • Supported data types are simple points, lines, or polygons stored in a database. Complex data types such as Terrains, Topologies, or Network Datasets are not supported as input.

  • Versioned data is not supported as input. Data must be unregistered as versioned before the tool will execute successfully.

  • Truncate commands do not utilize database transactions and are unrecoverable. This improves performance over row-by-row deletion.

  • For workflows where all rows are removed from a table or feature class and there is no need to back up the transactions, such as nightly reloading of data, it is recommended that this tool be used to perform the task.
