如何将数据插入主键和外键

Question

I have three tables:

PATIENT DETAILS

ptID

firstName

lastName

address

IMPLANT DETAILS

impID

ptID

productID

productSerialNo

PRODUCT

productID

productName

---

I am inserting data in PATIENT DETAILS and IMPLANT DETAILS table on the same page from single button click .

I have a foreign key on the table IMPLANT DETAILS (productID) which I populate through the value on the dropdown list.

What my problem is how will I populate foreign key (ptID) in IMPLANT DETAILS table? When ptID (PATIENT DETAIL) will also be generated from the same button click at almost of the same time. How would I do this in C#?

Answer 1

I suggest you to use entity framework for this. Please look this post Inserting Objects

Answer 2

You need to fire two sql queries to do this.

INSERT INTO PATIENT_DETAILS (firstName,lastName,address) VALUES(NULL,'text');         
INSERT INTO IMPLANT_DETAILS(ptID,productID,productSerialNo) VALUES(LAST_INSERT_ID(),1,'text'); 
COMMIT;
