Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type DbContext. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

The stored procedure name is determined by looking for the UpdateEntityStoredProcedureAttribute on the entity type. The stored procedure must have parameters for each of the entity properties except those marked with the IgnoreAttribute for updates. It should not return a value or a result set. Parameters marked with the TimestampAttribute are defined as input/out parameters. All other parameters are input only.

If the connection is not in an open state, it is opened temporarily while updating the entity. If change tracking is enabled on the data context and the entity its state will be set to unchanged.

Example

C#

using var dataContext = new MyDbContext();

if(watchListItem.WatchID == 0)
    dataContext.InsertEntity(watchListItem);
else
    dataContext.UpdateEntity(watchListItem);
