Hi,

Is there a way in dotConnect for ORACLE and EF to have the key value be populated automatically from a SEQUENCE?

I don't have control over the tables so I can't add a trigger to do this.

I can probably figure out a way to extract the connection string from the EF model and create a normal ADO.NET connection to get the NEXTVAL and then populate it in my entity prior to saving...

But, it would be nice if there was a way to put it in the model.

Thank you! Great product!

The other way is to set the values for Entity Key using ADO.NET SQL command. Here is a simple way to get the store connection from ObjectContext:
