Is this possible with sql?

Question

Is it possible to do something like this:

INSERT INTO table(col1, col2) VALUES(something_from_another_table, value);

With something_from_another_table being a SQL command? Like, is there something I can do that's equivelant to:

INSERT INTO table(col1, col2) VALUES((SELECT value FROM table2 WHERE id = 3), value);

Answer 1

Yes

INSERT INTO table(col1, col2) 
SELECT value1, 'value2' FROM table2 WHERE id = 3

Where value1 is the value from the 'other table' and value2 is a constant that you've included in that select statement.

Answer 2

Try this:

INSERT INTO table(col1, col2) 
SELECT table2.value1, value2 FROM table2 WHERE table2.id = 3;

Answer 3

http://dev.mysql.com/doc/refman/5.1/en/insert-select.html

take a look especially in the examples.

I would recommend reading full syntax of SELECT, UPDATE, DELETE and INSERT SQL commands to begin with. Then expand to subqueries and DDL.

Go slowly and work out examples.
