Question

您好在此代码中显示错误：

[＆＃34; 1062：重复录入＆＃39;＆＃39;对于密钥＆＃39; reg_no＆＃39;＆＃34;]

任何人都可以帮助我。添加名称为reg_no的字段时，为什么会显示此错误重复条目。

如果执行查询，我想返回true。

PHP

mysql_connect("localhost","root",""); 
mysql_select_db("hms");

Answer 1

如果您尝试添加已存在的记录（注册号），则可能是您将reg_no用作主键或唯一，但是显示该错误。

Answer 2

在您的表reg_no中primary key。您正尝试向注册表添加注册号的重复条目。将reg_no字段设为auto_increment，并将reg_no保留在insert上。新查询看起来像

INSERT INTO patient_registration(patient_main_type_id,   patient_type_id,initial_id,first_name,middle_name,last_name,fth_mth_name,religion_id,date_of_birth,caste_id,address,pin,email,id_proof,phone_office,    phone_residence,mobile_no,name_of_kin,relationship,entry_date,entry_time,patient_photo,payment_mode)
                VALUES('$pmc','$pc','$initial_id','$first_name','$middle_name','$last_name','$fh','$religion_id','$dob','$caste_id','$address','$pin','$email','$id_proof','$phone_office','$phone_resi','$mobile_no','$name_of_kin','','','$relation','$photo','$pmode')";

Mysql：1062：为密钥'reg_no'重复输入''
