속성

	이름	설명
	ConstrainedExecutable	Returns the name of a constrained container. This property is read-only.
	CreationName	Returns the string used by the Integration Services runtime to create an instance of the PrecedenceConstraint object and add the object to the PrecedenceConstraints collection. This property is read-only.
	Description	Gets or sets a description for the constraint.
	EvalOp	Gets or sets the evaluation operations used by the precedence constraint.
	EvaluatesTrue	Returns the Boolean value of the Value property. This property is read-only.
	Expression	Gets or sets the expression that the precedence constraint uses if EvalOp is set to Expression, ExpressionAndConstraint, or ExpressionOrConstraint.
	ID	Returns the GUID of the precedence constraint. This property is read-only.
	LogicalAnd	Gets or sets a Boolean that indicates whether multiple constraints work together.
	Name	Gets or sets the unique name of the precedence constraint.
	PrecedenceExecutable	Returns the name of the precedence executable. This property is read-only.
	Site	인프라입니다.
	Value	Gets or sets the constraint type of Success, Failure, or Completion.

메서드

	이름	설명
	Dispose	This method is inherited from the IDisposable.Dispose method, which is a generic mechanism to explicitly tell an object to perform cleanup.
	Equals	Determines whether two object instances are equal. (DtsObject에서 상속됨)
	Finalize	(Object에서 상속됨)
	GetHashCode	Returns the hash code for this instance. (DtsObject에서 상속됨)
	GetType	(Object에서 상속됨)
	LoadFromXML	This method is not callable by your application code. To load a package containing precedence constraints that are saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	(Object에서 상속됨)
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
	ToString	(Object에서 상속됨)

주의

You can specify the precedence and constrained executables that the precedence constraint connects, the expression and constraint that determine whether the constrained executable runs, and whether the precedence constraint works in concert with other precedence constraints.
