/**
 * Represents a command to fetch data from a specific table, with an optional row ID filter.
 *
 * The `FetchCommand` is designed to retrieve data from a table in the database. You can
 * specify a particular row by providing its ID. If no ID is provided, all rows from the table
 * will be fetched.
 *
 * The command performs the following actions:
 * - Constructs a query to fetch data from the specified table.
 * - Optionally filters the result by the provided row ID.
 *
 * This allows for retrieving specific rows from a table, or fetching all rows if no ID is given.
