ALTER TABLE 只允許加入可包含 Null 或已指定 DEFAULT 定義的資料行，或加入的資料行是識別或時間戳記資料行，或者，如果上述條件都不符合，資料表就必須是空的，以允許加入此資料行。資料行 '%1' 無法加入至非空白資料表 '%2'，因為它不符合這些條件。

ALTER TABLE only allows columns to be added that can contain nulls, or have a DEFAULT definition specified, or the column being added is an identity or timestamp column, or alternatively if none of the previous conditions are satisfied the table must be empty to allow addition of this column. Column '%1' cannot be added to non-empty table '%2' because it does not satisfy these conditions.
