ComputedText Property

后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The ComputedText property contains the Transact-SQL expression used to generate the value of a computed column.

语法

object.ComputedText [=value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    A string

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetComputedText(SQLDMO_LPBSTR pRetVal);
HRESULT SetComputedText(SQLDMO_LPCSTR NewValue);
注意注意

SQL Distributed Management Objects (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.

注释

A number of restrictions apply to the Transact-SQL statements available when a computed column is defined. For more information, see CREATE TABLE (Transact-SQL).
