在SQL Server 中,numeric和decimal資料類型的預設最大有效位數為 38。 數值資料類型的長度是用來儲存數字的位元組數目。 對於varchar和char,字元字串的長度是位元陣數目。 對於nvarchar 和nchar,字元字串的長度是位元組配對的數目。binary、varbinary及image資料類型的長度為位元組的數目。 例如,int資料類...
為了維持正確性,decimal 或 numeric 類型一律是以完全符合的精確度與小數位數擷取為字串。 如果任何值小於 1,則會遺漏前置零。 money 和 smallmoney 欄位也是如此,因為其為小數位數固定為 4 的 decimal 欄位。 若遺漏前置零則加以新增 從5.6.0 版開始,連線或陳述式屬性PDO::SQLSRV_ATTR_FORMAT_DECIMAL...
