MaximumLength 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。

説明
For binary and character data types, the MaximumLengthproperty identifies the greatest number of bytes required to store a string of the type. For example, the SystemDatatypeobject referencing the varchar data type reports 8,000. The varchar data type can contain up to 8,000 bytes of data. The number of characters contained in the string is determined by the mix of single and multibyte characters within it.
For the fixed-precision, numeric data types, the MaximumLength property specifies the maximum precision of the type.
For all other referenced data types, the MaximumLengthproperty identifies the number of bytes required to store a value of the type in a Microsoft SQL Server structure representing the type.
