FillFactor 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。新規の開発作業ではこの機能を使用しないようにし、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ことを検討してください。

解説
Microsoft SQL Server primary keys are supported by unique indexes built on the columns participating in the PRIMARY KEY or UNIQUE key constraint. For the Key object, the FillFactor property only has meaning if the Type property reports SQLDMOKey_Primary.
FillFactor can only be set when an Index object is created. It is a read-only property if an Index object references an existing SQL Server index.
Setting FillFactor on index or key creation can cause unintended behavior. For more information, see CREATE INDEX (Transact-SQL).
