BindDefault Method
后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能,并着手修改当前还在使用该功能的应用程序。
The BindDefault method implements Microsoft SQL Server default binding and unbinding for columns and user-defined data types.
语法
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.

---|
When you use the UserDefinedDatatype object, the bFutureOnly parameter is available in C/C++ applications. |
注释
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.
