MySQL从另一个表插入值

Question

I have two tables : table1(t1_id, t1_name) , table2(t2_id, t1_id) .

now if i try to insert value into table2 like this:

INSERT INTO table2(t2_id, t1_id) values(110202,(SELECT t1_id FROM table1));

This create an error : "subquery returns more than 1 row", which means it can insert only one row. But i want to insert all cartesian product.

Answer 1

May be you are looking for this

INSERT INTO table2(t2_id, t1_id)

SELECT 110202,t1_id FROM table1
