Question

I’m sorry for this noob question.

There’re 2 tables: the smaller one is derived from bigger one.
How do i insert new record into bigger table??

INSERT INTO people (lname, fname, city, age, salary) VALUES (' Doe','John','Paris', '25','1000$' );

but bigger table contains city as number. How should i insert ‘Paris’?? Should i know its number beforehand?? But ‘Paris’ isn’t in Cities (smaller) table!!
How do records get inserted in bigger (people) table??

Answer 1

EDIT:

Added IF block to check for Paris.

IF NOT EXISTS (SELECT 1 FROM City WHERE City = 'Paris')
Insert INTO City (City) VALUES ('Paris')

DECLARE @Cid int = (SELECT CityID FROM City WHERE City = 'Paris')

INSERT INTO people (lname, fname, city, age, salary) 
VALUES (' Doe','John', @cid, '25','1000$' )

I made an assumption about the structure of the city table obviously.

You could also parameterize this with a @city variable and sub that for 'Paris' everywhere in the code.
