如何从另一个表中插入值以及SQL Server中的其他值？

Question

I'm working on a project in which i need to insert data from one table to another along with another value, lets say I have table1(col1,col2,col3) and i have table2(col2) so i wrote the following:-

INSERT INTO table1 (col1,col2) VALUES ((@constant),(SELECT col2 FROM table2))

How to do that knowing that @Constant is a parameter that has a value used inside a stored procedure?

Answer 1

INSERT INTO table1 (col1,col2) 
SELECT @constant, col2 
FROM table2
