GetColumnBinary Method

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 GetColumnBinary method returns a void pointer to the memory that implements storage of a binary data type.

語法

object.GetColumnBinary(Row, Column)asInteger

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 GetColumnBinary(
long lRow,
long lCol,
LPVOID* ppData);

Returns

A long integer representation of a void pointer.

備註

The GetColumnBinary method has usefulness for the developer using an automation controller when the automation controller, used to develop a SQL Distributed Management Objects (SQL-DMO) application, supports a memory address as a data type.

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