BindRule Method
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa caratteristica in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The BindRule method implements Microsoft SQL Server rule binding and unbinding for columns and user-defined data types.
Sintassi
object
.BindRule(
RuleOwner
,
RuleName
,
Bind [,bFutureOnly])
Parts
object
Expression that evaluates to an object in the Applies To list.RuleOwner
String identifying the database user owning the bound rule.RuleName
String identifying the bound rule 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 BindRule(SQLDMO_LPCSTR RuleOwner,
SQLDMO_LPCSTR RuleName, BOOL Bind, BOOL bFutureOnly);
Settings
When Bind is TRUE, the rule named is bound to the column or user-defined data type referenced.
When Bind is FALSE, any rule is unbound from the referenced column or user-defined data type. The RuleOwner and RuleName properties are ignored.
Nota
When you use the UserDefinedDatatype object, the bFutureOnly parameter is available in C/C++ applications.
Osservazioni
The BindRule method of the Column or UserDefinedDatatype objects, and the BindToColumn and BindToDatatype methods of the Rule object, associate a SQL Server rule with a user-defined data type or column.
The BindDefault method does not cause a check of existing values when a new rule is indicated for a column or user-defined data type.
