BindDefault Method

Questa funzionalità verrà rimossa in 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 BindDefault method implements Microsoft SQL Server default binding and unbinding for columns and user-defined data types.

Sintassi

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.

[!NOTA] When you use the UserDefinedDatatype object, the bFutureOnly parameter is available in C/C++ applications.

Osservazioni

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.

Applies to:

Column Object

UserDefinedDatatype Object
