MaximumChar Property
この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。 新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。
The MaximumChar property returns the maximum number of characters used when a value of the data type is converted to a character string.

説明
Characters such as string terminators are not included in the character count.
The MaximumChar property returns a character count, not the number of bytes required to store a string of that length. The MaximumLength property can return the number of bytes required to store a value for a data type.
For example, for the SystemDatatype object that references the nchar data type, MaximumChar returns 4,000. The MaximumLength property for the object returns 8,000, because each nchar character requires two bytes for storage.
