During the training I lead this week, one of my interns tried to stick me by giving me a base to which the use of EF was, supposedly, not possible. dta srs Fortunately, my honor and that of the RU except ...
Value is an integer between 1 and 9 can no longer dta srs change once it is assigned and Key is equal to Id * 10 + Value Inheriteds a table with 3 columns: id, int, Indentity (PK) Key, int, not null Text2, dta srs nvarchar
Key is the same as in the table bases and therefore, it was actually a 1 -> 0..1 between bases and Inheriteds although this relationship does not exist in the database. Descriptions of a table with 4 columns: id, int, Identity dta srs (PK) Key, int, not null Language, dta srs Text nchar, nvarchar
CSDL side (description of entities), he wanted to have one class Base asbtraite (mapped Bases) an Entity class that inherits from Base (mapped Inheriteds) a Class Description a 1 -> * between base and Description
How to do this? First, the designer, after importing the tables and have renamed entity type generated, he dupprimer the Id property dta srs of each of them. Then, define Base.Key, Description.Key and Description.Language as EntityKey. dta srs Base Set as abstract Delete Entity.Key Add the inheritance relationship between Entity and Base and update the mapping Entity (ie: you have to map the Key column on the Base.Key property) Add the relationship between base and Description
<Property Name = "Key" type = "int" Nullable = "false" StoreGeneratedPattern = "Computed" />
<PropertyRef Name = "Key" />
UPDATE Bases
SET [Text] =Text
</ CommandText>
</ MappingFragment>
</ ModificationFunctionMapping>
You made me dive in ED ... I struggled at first because I had the base type was anything but ideal ... and with your tickets that put me on the tracks ... I always managed to get what I wanted.
Roll on the weekend lol
I still have a lot of questions about the EF (the opposite would be surprising given the size of the tool ...), it was Julia Lerman we had advised you (I've seen it was a book about the EF O'Reilly)?
