Hello,

I try to create edm for sqlerver and oracle server.
So I created one csdl which I use for both databases and I generated the msl and ssdl foreach database.
The csdl is created from sql server and all ids are Int32 and the datatype of the column in sql server is int.
Now I generate the ssdl and the msl for the oracle database.
However, in the ssdl for oracle the datatype of the ids is Int64 while the datatype of the oracle column is Number(10,0).
So when I try to save something into the oracle database i get an error because the datatype in the ssdl is Int64 and the datatype in csdl is Int32.

Any clue to solve this problem?

Such mapping is used to prevent the overflow on the client side.
You can manually modify the SSDL part of the generated model using any XML Editor you like and set the type of your property
according to your needs.

If I change the datatype in ssdl to int32 I get the error that the datatype is not known in the namespace.

The correct synonym for the Int32 data type is "int".
