Methods

AddColumnModification(ColumnModificationParameters)	Creates a new IColumnModification and add it to this command.
AddEntry(IUpdateEntry, Boolean)	This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.
AssertColumnsNotInitialized()	This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.
CreateColumnModification(ColumnModificationParameters)	Creates a new instance that implements IColumnModification interface.
ProcessSinglePropertyJsonUpdate(ColumnModificationParameters)	Performs processing specifically needed for column modifications that correspond to single-property JSON updates.
PropagateOutputParameters(DbParameterCollection, Int32)	Reads output parameters returned from the database in the given parameterCollection and propagates them back to into the appropriate IColumnModification from which the values can be propagated on to tracked entities.
PropagateResults(RelationalDataReader)	Reads result set columns returned from the database in the given relationalReader and propagates them back to into the appropriate IColumnModification from which the values can be propagated on to tracked entities.
ToString()	Returns a string that represents the current object.
