I am trying to create a record in the db that has a predefined primary key value. I know how to do this with sql, but I was wondering if EF can do this for me? Otherwise, I will have to create a stored proc for the inserts.
In case you have the
StoreGeneratedPattern attribute set to "None" for your entity, the Entity Key value you specify for it will be passed to database.
In case this attribute is set either to "Identity" or to "Computed" there is no way to control what value will be set to this column in DB.
So, if you have an auto-incremented column in your database and the ADO.NET Entity Data Model wizard has set the
StoreGeneratedPattern for you, you can manually change this attribute to "None" in the SSDL part of the model using XML Editor, and then enable
You can use the
ObjectContext.ExecuteStoreCommand method if you are using EF4 or use the
ObjectContext.Connection.StoreConnection property to execute a SQL command
SET IDENTITY_INSERT <Your_Table> ON (both in EF1 and EF v4).
