BindDefault 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 BindDefault method implements Microsoft SQL Server default binding and unbinding for columns and user-defined data types.

Syntaxe

object
.BindDefault(
DefaultOwner
,
DefaultName
,
Bind [,bFutureOnly])

Parts

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

• DefaultOwner
  String identifying the database user owning the bound default.

• DefaultName
  String identifying the bound default by name.

• Bind
  TRUE or FALSE as described in Settings.

• bFutureOnly
  TRUE or FALSE. This is an optional parameter that applies only to the UserDefinedDatatype object.

Prototype (C/C++)

HRESULT BindDefault(SQLDMO_LPCSTR DefaultOwner,
SQLDMO_LPCSTR DefaultName, BOOL Bind, BOOL bFutureOnly);

Settings

When Bind is TRUE, the default named is bound to the column or user-defined data type referenced.

When Bind is FALSE, any default is unbound from the referenced column or user-defined data type. The DefaultOwner and DefaultName properties are ignored.

Remarque :
When you use the UserDefinedDatatype object, the bFutureOnly parameter is available in C/C++ applications.

Notes

The BindDefault method of the Column or UserDefinedDatatype object, and the BindToColumn and BindToDatatype methods of the Default object, associate a SQL Server default with a user-defined data type or column.

The BindDefault method does not cause a check of existing values when a new default is indicated for a column or user-defined data type.
