Script Method (Table Object)
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 Script method generates a Transact-SQL command batch that can be used to re-create the Microsoft SQL Server component referenced by the SQL Distributed Management Objects (SQL-DMO) object.

SQL-DMO strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString. |

説明
The Script method generates a Transact-SQL command batch that defines an existing SQL Server table. The Table object supports command batch generation when using the object to define a new table. Use the GenerateSQL method when capturing new table definition. Use the Script method when capturing an image of an exiting table. When using the Script method as part of an application process re-creating a table, specify SQLDMOScript_Drops in the ScriptType argument to include a drop of the existing table in the command batch.
| 注意 |
|---|
SQL-DMO object scripting methods are fully compatible with an instance of SQL Server version 7.0. However, database compatibility level affects Transact-SQL command batch contents. |
When scripting a database with a compatibility level of less than 7.0, or when scripting any of its objects, the resulting Transact-SQL command batch includes only keywords reserved by that level.
Transact-SQL command syntax is always compliant with an instance of SQL Server 7.0. Where provided, you can use optional scripting arguments, such as SQLDMOScript2_NoFG to remove some syntax of an instance of SQL Server version 7.0.
