Oracle.DataAccess.Client maps Number(10,0) to both Long and Decimal
Lars Pedersen
Member Posts: 21
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:

That shouldn't be happening. Do you have a test case? The same .NET numeric data type should be used by the .NET DataTable.

The SQL is long and contains a WITH and a UNION statement. Maybe later I can create a test case.
