GetColumnGUID Method

Cette fonctionnalité sera supprimée dans une prochaine version de Microsoft SQL Server. Évitez d'utiliser cette fonctionnalité dans de nouveaux travaux de développement et prévoyez de modifier les applications qui utilisent actuellement cette fonctionnalité.

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

Syntaxe

object
.GetColumnGUID(
Row
, 
Column
)
as
Integer

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

Notes

The GetColumnGUID 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.
