how to insert data with where cause - php

Question

create table cmu_patient
( patient_id character varying(13) NOT NULL,
patient_hn character varying(7),
patient_fname character varying(50),
patient_lname character varying(50),
home_id integer,
CONSTRAINT cmu_patient_pkey PRIMARY KEY (patient_id),
CONSTRAINT Fk_home FOREIGN KEY(home_id)
REFERENCES cmu_home(home_id)
);
create table cmu_treatment
( treatment_id serial NOT NULL,
treatment_date date,
treatment_time time without time zone,
treatment_typecome character varying(100),
treatment_detail text,
patient_id character varying(13),
appointment_id character varying(5),
transfer_id character varying(5),
res_users_id integer,
CONSTRAINT cmu_treatment_pkey PRIMARY KEY (treatment_id),
CONSTRAINT Fk_patient FOREIGN KEY(patient_id)
REFERENCES cmu_patient(patient_id),
CONSTRAINT Fk_user_id FOREIGN KEY(res_users_id)
REFERENCES res_users(id)
);
$treatment_date = $GET_[...];
$treatment_time = $GET_[...];
$treatment_typecome = $GET_[...];
$treatment_note = $GET_[...];
$CID = $GET_[...];
this code -------- it's incorrect
INSERT INTO cmu_treatment(treatment_id, treatment_date, treatment_time,
treatment_typecome, treatment_detail, patient_id, appointment_id,transfer_id, res_users_id)
VALUES(NULL,'".$tratment_date."','".$treatment_time."','".
$treatment_typecome."','".$treatment_note."','".$CID."',NULL,NULL,NULL)
WHERE cmu_patient.patient_id = cmu_treatment.patient_id ;
i think that's wrong
i don't know if i want to write insert data into table with where cause i should write sql ?
thank :)

Answer 1

I suspect what you really want is an update, to change existing values in an existing record:
update cmu_treatment
set treatment_date = $treatment_date,
treatment_time = $treatment_time,
treatment_detail = $treatment_typecome,
treatment_note = $treatment_note
where patient_id = $CID;
(I'm leaving out the NULL values on the assumption that those shouldn't really change.)
If you do indeed want a new record, you can do:
INSERT INTO cmu_treatment(treatment_id, treatment_date, treatment_time,
treatment_typecome, treatment_detail, patient_id, appointment_id,
transfer_id, res_users_id
)
select NULL,'".$tratment_date."', '".$treatment_time."','".
$treatment_typecome."','".$treatment_note."','".$CID."', NULL, NULL, NULL;

Answer 2

You can write an INSERT statement populating target table with a SELECT statement. In the SELECT statement you can use WHERE condition.
So instead this query:
INSERT INTO table VALUES (....)
You must write:
INSERT INTO table
SELECT fields
FROM anothertable
WHERE condition
In your case, I think you must use an INSERT without WHERE condition if you want to insert only a row in your treatment table.
Tell me if you want to know further info
EDIT After comment
IMHO your statement must be:
INSERT INTO cmu_treatment
(treatment_id, treatment_date, treatment_time,
treatment_typecome, treatment_detail, patient_id, appointment_id,
transfer_id, res_users_id)
VALUES
(NULL,'".$tratment_date."','".$treatment_time."',
'".$treatment_typecome."','".$treatment_note."','".$CID."',NULL,NULL,NULL)

Answer 3

INSERT INTO `cmu_treatment`(`treatment_id`, `treatment_date`, `treatment_time`,
`treatment_typecome`, `treatment_detail`, `patient_id`, `appointment_id`,`transfer_id`, `res_users_id`)
VALUES(NULL,'".$tratment_date."','".$treatment_time."','".
$treatment_typecome."','".$treatment_note."','".$CID."',NULL,NULL,NULL)
WHERE `cmu_patient.patient_id` = `cmu_treatment.patient_id` ;
And you don't need (table name).(column).
Is this Inside "" ? If yes then you don't need '".$tratment_date."' you can use only '' so your code will look like this.
INSERT INTO cmu_treatment(treatment_id, treatment_date, treatment_time,
treatment_typecome, treatment_detail, patient_id, appointment_id,transfer_id, res_users_id)
VALUES(NULL,'$tratment_date','$treatment_time','
$treatment_typecome','$treatment_note','$CID',NULL,NULL,NULL)
WHERE `patient_id` = patient_id ;
And finally what is patient_id? Is it variable? If not IT MUST BE. Don't give same names to different things.
