Properties

IsDestructiveChange	Indicates whether or not the operation might result in loss of data in the database. (Inherited from MigrationOperation)
Item[String]	Gets the value annotation with the given name, returning `null` if it does not exist. (Inherited from Annotatable)
Name	The name of the check constraint.
Schema	The table schema that contains the check constraint, or `null` if the default schema should be used.
Sql	The logical sql expression used in a CHECK constraint and returns TRUE or FALSE. Sql used with CHECK constraints cannot reference another table but can reference other columns in the same table for the same row. The expression cannot reference an alias data type.
Table	The table of the check constraint.

Methods

CreateAnnotation(String, Object)	Creates a new annotation. (Inherited from Annotatable)
EnsureMutable()	Throws if the model is read-only. (Inherited from Annotatable)
EnsureReadOnly()	Throws if the model is not read-only. (Inherited from Annotatable)
FindAnnotation(String)	Gets the annotation with the given name, returning `null` if it does not exist. (Inherited from Annotatable)
GetAnnotations()	Gets all annotations on the current object. (Inherited from Annotatable)
GetOrAddAnnotation(String, Object)	Adds an annotation to this object or returns the existing annotation if one with the specified name already exists. (Inherited from Annotatable)
OnAnnotationSet(String, Annotation, Annotation)	Called when an annotation was set or removed. (Inherited from Annotatable)
RemoveAnnotation(String)	Removes the given annotation from this object. (Inherited from Annotatable)
SetAnnotation(String, Annotation)	Sets the annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from Annotatable)
SetAnnotation(String, Annotation, Annotation)	Sets the annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from Annotatable)

Explicit Interface Implementations

IAnnotatable.FindAnnotation(String)	Gets the annotation with the given name, returning null if it does not exist. (Inherited from Annotatable)
IAnnotatable.GetAnnotations()	Gets all annotations on the current object. (Inherited from Annotatable)
IMutableAnnotatable.AddAnnotation(String, Object)	Adds an annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from Annotatable)
IMutableAnnotatable.RemoveAnnotation(String)	Removes the given annotation from this object. (Inherited from Annotatable)

Extension Methods

GetAnnotation(IAnnotatable, String)	Gets the annotation with the given name, throwing if it does not exist.
AddAnnotations(IMutableAnnotatable, IEnumerable<IAnnotation>)	Adds annotations to an object.
GetAnnotation(IMutableAnnotatable, String)	Gets the annotation with the given name, throwing if it does not exist.
SetOrRemoveAnnotation(IMutableAnnotatable, String, Object)	Sets the annotation stored under the given name. Overwrites the existing annotation if an annotation with the specified name already exists. Removes the existing annotation if `null` is supplied.
