GetColumnBinary Method

Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

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

Sintassi

Parts

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

  • Row

Prototype (C/C++)

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

Osservazioni

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.
