我已经创建了一个函数postgres,它使用折射符从不同的表返回两个结果集。现在,我想从C#调用这个函数,但是通过硬编码游标名,每次只能调用一个游标,这一点都不理想。npgsqlCommand= newNpgsqlCommand(query, npgsqlConnection);npgsqlCommand.ExecuteNonQuery();
(var reader1 = cmd1.ExecuteReader()) { while (reader1.Read()) { // 处理第一个命令的结果 } reader1.Close(); // 确保关闭读取器 } using (var cmd2 = new NpgsqlCommand("UPDATE table2 SET column1 = value1", conn)) { cmd2.ExecuteNonQuery(); // 执行第二个命令 } // 确保在离开 ...
Looking at the Sql Server example, there is timeout-specific SqlException.Number value of -2: try { cmd.ExecuteNonQuery(); } catch (SqlException ex) when (ex.Number == -2) { // timeout } while SqlException.Numbervalue of10060` has its separate place in life. It is also used for t...
