GetColumnSQLVARIANTToString 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 GetColumnSQLVARIANTToString method converts a sql_variant column to a string and returns its value.

Syntaxe

object
.GetColumnSQLVARIANTToString( 
Row
, 
Column
, 
ObjName
)
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.

  • ObjName
    String that specifies a table or view name.

Prototype (C/C++)

HRESULT GetColumnSQLVARIANTToString(
long lRow, 
long lColumn, 
SQLDMO_LPCSTR ObjName, 
SQLDMO_LPBSTR pRetVal);

Notes

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.

Notes

GetColumnSQLVARIANTToString can be useful in applications designed to display the contents of sql_variant columns, such as a Web site.

Columns with underlying numeric, decimal, or datetime data types cannot be converted to strings using the GetColumnSQLVARIANTToString method.

Notes

If an application calls GetColumnSQLVARIANTToString on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
