GetColumnString Method

未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能，並計劃修改目前使用此功能的應用程式。

The GetColumnString method returns a QueryResults object result set member converted to a String value.

語法

object
.GetColumnString(
Row
, 
Column
)
as
String

Parts

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

• Row
  Long integer that identifies a row by ordinal position.

• Column
  Long integer that identifies a column by ordinal position.

Prototype (C/C++)

HRESULT GetColumnString(
long lRow,
long lCol,
SQLDMO_LPBSTR pRetVal);

附註：
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.

Returns

A String representation of the value of a QueryResults result set member.

備註

When converting a value of any data type to string, conversion rules are those applied for the locale of the client workstation.

The Row and Column Parameters are 1-based in Visual Basic applications, and are zero-based in C++ applications.
