Oracle.DataAccess.Client maps Number(10,0) to both Long and Decimal

Lars PedersenMay 29 2019 — edited Jun 3 2019

In a .NET program, I am using Oracle.DataAccess.Client (from Oracle.DataAccess.dll v. 2.112.1.0) to retrieve data from an Oracle database using a SELECT statement.

2 of the fields are typed as Number(10,0).

In the resulting .NET DataTable object, one of the columns is a Long (Int64) datatype, the other is a Decimal datatype. Why is that?

I found this page that claims that the default datatype mapping from Number(10,0) is Int32:

I have the same error simply by deploying ORDS on Tomcat locally. I'm using ORDS (21.1.3.153.1102) and Tomcat (10.0.11) installed on windows 10.

I never found the solution for the issue, but I believe it was related to Tomcat 10.x. I downgraded Tomcat to version 9 and the error went away.

Yes, ORDS will absolutely NOT work on Tomcat 10 today.
