ORA-01460: unimplemented or unreasonable conversion requested

Question

When I run the following .Net code:

using (var c = Shared.DataSources.BSS1.CreateCommand())
{
    c.CommandText = \"\\r\\nSelect c1, c2, c3, rowid \\r\\nFrom         


        

Answer 1

Finally I found the answer!!!

After investigating and reflecting into the code I found that by changing the Direction of the Parameter to input output - the problem was resolved.

p.Direction = ParameterDirection.InputOutput;
