Hi,

I have a table for which the primary key is Number(19,0)
( on Oracle).
The key in the model is mapped to int64 ( in conceptual and storage layer).

When i make a query, the gererated sql looks like :
SELECT *
FROM AFDA.AFDA_VRGESCHR_ZORGEN "Extent1"
WHERE ( CAST("Extent1".PATIENT_NR AS NUMBER)) = 15505;

So the SQL casts the key as number even when it is already a number.
This makes it so that my index on 'PATIENT_NR' is not used.

I Map the Property to INT64 becus i want to use long in code instead of decimal !

Is there anything i can do to fix this mapping problem ?

greetings

Could i fix this with numbermappings ?

but i am not working with datareaders, i am working with Entity framework, and my context.connection does not have a numbermappings
property so i will probably have to cast it to oracle connection ?
-> yeps, that worked,
still :
an easier way for me would be the connection string:

but i havent found any documentation how to specify this in the connection string ? any help ?
