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

This problem can be recreated with straight forward steps. That is, any SQL query having a string literal, in where clause, more than 4000 characters in length gives an error "ORA-01704: string literal too long"

But, when the same query is executed through JDBC it gives "ORA-01460: unimplemented or unreasonable conversion requested"
