C# OracleDbType equivalent - for Oracle datatype char

Question

I want to pass a single CHAR to an oracle sp.

I tried using:

cmd.Parameters.Add("i_flag", OracleDbType.Varchar2, flag, ParameterDirection.Input);

where flag is a C# char but it gives Overflow exception.

I also tried:

cmd.Parameters.Add("i_flag", OracleDbType.Char, flag, ParameterDirection.Input);

but it gives same exception.

Even the below gives the same exception:

cmd.Parameters.Add("i_flag", OracleDbType.Varchar2, flag.ToString(), ParameterDirection.Input);

Can you please tell what is the correct parameter type that I should pass.

Thanks, Varun

Answer 1

More analysis revealed that the overflow was due to some arithmetic operation being done in stored procedure.

We need to truncate the decimal before sending it to .NET

Thanks for all the help though.
