Properties

EntityType	Gets the entity type on which this check constraint is defined.
Item[String]	Gets the value of the annotation with the given name, returning `null` if it does not exist. (Inherited from IReadOnlyAnnotatable)
ModelName	Gets the name of the check constraint in the model. (Inherited from IReadOnlyCheckConstraint)
Name	Gets the name of the check constraint in the database.
Sql	Gets the constraint sql used in a check constraint in the database.

Methods

AddRuntimeAnnotation(String, Object)	Adds a runtime annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from IAnnotatable)
AnnotationsToDebugString(Int32)	Gets the debug string for all annotations declared on the object. (Inherited from IReadOnlyAnnotatable)
FindAnnotation(String)	Gets the annotation with the given name, returning `null` if it does not exist. (Inherited from IReadOnlyAnnotatable)
FindRuntimeAnnotation(String)	Gets the runtime annotation with the given name, returning `null` if it does not exist. (Inherited from IAnnotatable)
FindRuntimeAnnotationValue(String)	Gets the value of the runtime annotation with the given name, returning `null` if it does not exist. (Inherited from IAnnotatable)
GetAnnotation(String)	Gets the annotation with the given name, throwing if it does not exist. (Inherited from IReadOnlyAnnotatable)
GetAnnotations()	Gets all annotations on the current object. (Inherited from IReadOnlyAnnotatable)
GetDefaultName()	Returns the default database name that would be used for this check constraint. (Inherited from IReadOnlyCheckConstraint)
GetDefaultName(StoreObjectIdentifier)	Returns the default database name that would be used for this check constraint. (Inherited from IReadOnlyCheckConstraint)
GetName(StoreObjectIdentifier)	Gets the database name of the check constraint. (Inherited from IReadOnlyCheckConstraint)
GetOrAddRuntimeAnnotationValue<TValue,TArg>(String, Func<TArg,TValue>, TArg)	Gets the value of the runtime annotation with the given name, adding it if one does not exist. (Inherited from IAnnotatable)
GetRuntimeAnnotations()	Gets all the runtime annotations on the current object. (Inherited from IAnnotatable)
RemoveRuntimeAnnotation(String)	Removes the given runtime annotation from this object. (Inherited from IAnnotatable)
SetRuntimeAnnotation(String, Object)	Sets the runtime annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from IAnnotatable)
ToDebugString(MetadataDebugStringOptions, Int32)	Creates a human-readable representation of the given metadata. Warning: Do not rely on the format of the returned string. It is designed for debugging only and may change arbitrarily between releases.
