.Net Core 调用Oracle 存储过程

安装nuget包

Oracle.ManagedDataAccess.Core

注意

ParameterDirection.InputOutput 输入输出参数
参数最好指定长度

            try
            {
                var constr = GetConfig("OracleConn");
                using var con = new OracleConnection(constr);
                con.Open();

                // Call stored procedure
                var odbcCommand = con.CreateCommand();
                odbcCommand.CommandText = "SP_";
                odbcCommand.CommandType = CommandType.StoredProcedure;

                var codePara = new OracleParameter("Code", OracleDbType.Varchar2, ParameterDirection.InputOutput)
                {
                    Value = Code
                };
                var TypePara = new OracleParameter("Type", OracleDbType.NVarchar2, 20, null, ParameterDirection.Output);

                odbcCommand.Parameters.Add(codePara);
                odbcCommand.Parameters.Add(TypePara);

                odbcCommand.ExecuteNonQuery();

                Code = codePara.Value;
                Type = TypePara.Value;

                // Close and Dispose OracleConnection
                con.Close();
            }
            catch (OracleException oex)
            {
                Code = "";
                Type = "";
            }
