Constructors

ModificationCommand(ModificationCommandParameters)	Initializes a new ModificationCommand instance.
ModificationCommand(NonTrackedModificationCommandParameters)	Initializes a new ModificationCommand instance.
ModificationCommand(String, String, Func<String>, Boolean, IComparer<IUpdateEntry>)	Initializes a new ModificationCommand instance.
ModificationCommand(String, String, Func<String>, Func<IProperty,IRelationalPropertyAnnotations>)
ModificationCommand(String, String, IReadOnlyList<ColumnModification>, Boolean)	Initializes a new ModificationCommand instance.
ModificationCommand(String, String, IReadOnlyList<ColumnModification>)	Initializes a new ModificationCommand instance.

Properties

ColumnModifications	The list of IColumnModification needed to perform the insert, update, or delete.
EntityState	The EntityState that indicates whether the row will be inserted (Added), updated (Modified), or deleted ((Deleted).
Entries	The IUpdateEntrys that represent the entities that are mapped to the row to update.
RequiresResultPropagation	Indicates whether the database will return values for some mapped properties that will then need to be propagated back to the tracked entities.
RowsAffectedColumn	When using a stored procedure, this optionally points to the output parameter or result column containing the rows affected.
Schema	The schema containing the table, or `null` to use the default schema.
StoreStoredProcedure	The stored procedure to use for updating the data.
Table	The table containing the data to be modified.
TableName	The name of the table containing the data to be modified.

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.
AddEntry(IUpdateEntry)	Obsolete. Adds an IUpdateEntry to this command representing an entity to be inserted, updated, or deleted.
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.
PropagateResults(ValueBuffer)	Reads values returned from the database in the given ValueBuffer 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.
