Truncate Table (Data Management)


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 and 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, and 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 use database transactions and are unrecoverable. This improves performance over row-by-row deletion.

  • It is recommended that this tool be use for workflows in which 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.

  • This tool does not support a feature service layer as input.
