How to pass boolean parameter to Oracle procedure C#

Question

I have problem to pass boolean parameter to my procedure in Oracle. I get error

ORA-06550: line 1, column 7:
  PLS-00306: wrong number or types of arguments         


        

Answer 1

Consider the following procedure as example

CREATE OR REPLACE PROCEDURE my_procedure
(
   condition NUMBER,...

In C#, add parameter

cmd.Parameters.Add("@condition", OracleDbType.Char).Value = myObject.isCondition ? 1 : 0;

Answer 2

Try using BindByName property of OracleCommand as true to force the data provider bind these parameters by name and not just for the index. You do not need to pass the ' as parameters. It is lead with parameters in the ado.net.

ODP.NET does not support Boolean data type. Just use 1 or 0 as a char value to persist it.

For Sample:

cmd = new Oracle.DataAccess.Client.OracleCommand("Vbank_pkg.vb_log_entry", con);

cmd.BindByName = true;
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add("p_rqserial", OracleDbType.Int32).Value = Log_Serial;
cmd.Parameters.Add("p_orig", OracleDbType.Varchar2).Value = p_orig;
cmd.Parameters.Add("p_type", OracleDbType.Char).Value = p_type;
cmd.Parameters.Add("p_objname", OracleDbType.Varchar2).Value = p_objname;
cmd.Parameters.Add("p_info", OracleDbType.Varchar2).Value = p_info;
cmd.Parameters.Add("p_text", OracleDbType.Varchar2).Value = p_text;
cmd.Parameters.Add("p_with_commit", OracleDbType.Char).Value = "1";

cmd.ExecuteNonQuery();
