hello sir , i have questions k foreign key to point krta he dosrey table k column ko jo k apne banaya CITYNAME k name se to CITY kese foreign key bana ? 2nd yeh k apne is tutorial main personal table k column city ki values to khud insert karwayen hain .. is ko khud pick nae hojana that city table se ?

[@YahooBaba]

1) Dekho ek table ki PRIMARY KEY point karti hai doosre table ki FOREIGN KEY KO, tabhi dono table join hote hai.
2) Dekho koi bhi value apne aap insert nahi hogi kisi table mein. Yha toh basically hum khud insert kar rahe hai leking jab MySQL ko kisi langauge ke sath use karenge jaise PHP toh wha se ek aisa system banayenge ki value khud insert ho jaye.

Sir altering the table is complicated since the data type of my city column in personal is Varchar and then making it a foreign key requires to change it's data type later it has messed up my table.

[@faisalmalik4988]

sir thankyou and!
sir hum id ko primary na set kare tw bhi kaam chal sakta hana q.k iska koi khas kaam tw nhi hai ?

[@YahooBaba]

Nahi bina Id ko primary set karne se kaam temporary hoga kyu ki duplicacy aa jayegi aur Kisi ek column ko primary key set karna zaroori hai agar aap baad mein joins bhi karna chahte ho

[@rohanaggarwal12]

Sir why you have taken city data type in personal table as INT ?
FOREIGN KEY SHOULD HAVE SAME data type as primary key of another table?

[@YahooBaba]

Because in another table "city" their is a column name "cid" whose data type is INT and that is also a PRIMARY KEY of "city" table.

[@sandipsandal]

is this necessary to name of both column be same like u_name = b_rented_user => should it be u_name

NO
