选择并插入mysql

Question

I would like to select one column from other table and insert it into another one.

I have column named image in table2 and want to select that and insert along with the below data to table1. is that possible?

$stmt = $mysqli->prepare("insert into table1 (username, firstname, lastname, image) ")
$stmt->bind_param('sss', $username, $fname, $lname);
$stmt->execute();

Answer 1

Yes, it's possible:

$stmt = $mysqli->prepare("
  insert into table1 (username, firstname, lastname, image) 
  select ?,?,?,image from table2
  ");

...but I hope table2 has only one row!

Answer 2

You could do a INSERT ... SELECT query - http://dev.mysql.com/doc/refman/5.1/en/insert-select.html

INSERT INTO table1 (username, firstname, lastname, image)
SELECT ?, ?, ?, image FROM table2 t2 WHERE t2.image_id = ?

The first 3 ? are your bound params - $username, $fname, $lname
t2.image_id = ? represents the id/unique field of your desired img.
