SQLSTATE [HY093]：参数号INSERT无效

Question

我需要在for (int i = tokens.Length - 6, i < tokens.Length; i++) { string searchHist = tokens[i]; if(userSettings.Length > refer) { output.Append("<li>" + searchHist + "</li>"); } } 表中进行插入，此表没有行。

Table Gynecology

另一个页面中的会话变量为2。

gynecology

$_SESSION ["id_patient"] = 2; <?php $insert = $db->prepare("INSERT INTO gynecology(id_patient, nvisita, date_visit, background, reason_visit, exploration, exploration_comp, diagnosis, treatment) SELECT IFNULL(gy.id_patient,:id_patient), IFNULL(max(gy.nvisita),0)+1, (now()), :background, :reason_visit, :exploration, :exploration_comp, :diagnosis, :treatment FROM gynecology gy, patients pa WHERE gy.id_patient = pa.id AND PA.ID = :id_patient"); $insert->bindParam(":background", $background); $insert->bindParam(":reason_visit", $reason_visit); $insert->bindParam(":exploration", $exploration); $insert->bindParam(":exploration_comp", $exploration_comp); $insert->bindParam(":diagnosis", $diagnosis); $insert->bindParam(":treatment", $treatment); $insert->bindParam(":id_patient", $_SESSION["id_patient"]); $insert->execute(); ?> 表包含患者的ID。

感谢。

你是错配的参数。改变：

            $insert = $db->prepare("INSERT INTO gynecology(id_patient, nvisita, date_visit, background, reason_visit, exploration, exploration_comp, diagnosis, treatment) 
                                    SELECT IFNULL(gy.id_patient,:id_patient), IFNULL(max(gy.nvisita),0)+1, (now()), :background, :reason_visit, :exploration, :exploration_comp, :diagnosis, :treatment
                                    FROM gynecology gy, patients pa
                                    WHERE gy.id_patient = pa.id
                                    AND PA.ID = :id_patient");

            // this first parameter is missing
            $insert->bindParam(":id_patient", $_SESSION["id_patient"]); 
            // the other parameters you have
            $insert->bindParam(":background", $background);
            $insert->bindParam(":reason_visit", $reason_visit);
            $insert->bindParam(":exploration", $exploration);
            $insert->bindParam(":exploration_comp", $exploration_comp);
            $insert->bindParam(":diagnosis", $diagnosis);
            $insert->bindParam(":treatment", $treatment);
            $insert->bindParam(":id_patient", $_SESSION["id_patient"]);
