    Truncating Apache Iceberg Tables

    The TRUNCATE command deletes all rows from a table with minimal computation by restating the table with no data files.

    note:

    This command is not supported on Amazon Glue datasources.

    Syntax 
    TRUNCATE [ TABLE ] [ IF EXISTS ] <table_path>.<table_name>

    Parameters

    TABLE

    String

    Optional

    Specifies that the object to be truncated is a table. If not used, the Dremio Cloud still recognizes that the object is a table. This option is for consistency with other query engines that can truncate the same tables that Dremio Cloud has access to on the datasource.

    [ IF EXISTS ]

    String

    Optional

    Prevents the datasource from returning an error message if a table with the same definition does not exist in the specified location.

    <table_name>

    String

    The name of the table that you want to truncate.
