/// <param name="tableName">
/// The name of the table that will be written to.
/// If a query is not provided this will also be the name of the table that data is read from.</param>
/// <param name="sqlBulkCopyOptions">Options used by <see cref="SqlBulkCopy"/>.</param>
/// <param name="query">An optional query that will be used as the source of data.</param>
/// <param name="queryParams">Optional parameters that are used by the source data query.</param>
