Script Method (Table Object)

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

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.

語法

object.Script( [ ScriptType ] [, ScriptFilePath ] [, NewName ] [, Script2Type ] )as String

Parts

  • object
    Expression that evaluates to an object in the Applies To list.

  • ScriptType
    Optional. A long integer that overrides default scripting behavior as described in Settings.

  • ScriptFilePath
    Optional. A string that specifies an operating system file as an additional target for the generated Transact-SQL script.

  • NewName
    Optional. A string that specifies a new name for the referenced table.

  • Script2Type
    Optional. A long integer that overrides default scripting behavior as described in Settings.

Prototype (C/C++)

HRESULT Script(
SQLDMO_SCRIPT_TYPE ScriptType = SQLDMOScript_Default,
SQLDMO_LPCSTR ScriptFilePath = NULL,
SQLDMO_LPCSTR NewName = NULL,
SQLDMO_LPBSTR ScriptText = NULL,
SQLDMO_SCRIPT2_TYPE Script2Type = SQLDMOScript2_Default);

[!附註]

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.

Settings

When setting the ScriptType argument specifying multiple behaviors, combine values using an OR logical operator. Use these values to set ScriptType.

備註

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.

[!附註]

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.
