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.
