PHP mysql auto insert timestamp

Question

Say I have a table name auto_parts with these fields. id, part, price, timestamp and I insert a new row via php as so:

$query = "insert into auto_parts(id, part, price, timestamp)
  values(1, 'axle', 200)"
mysql_query($query);

will that automatically add the timestamp. Or do I have to insert a value for timestamp myself?

Answer 1

What you need to do is declare timestamp to be of type in your sql

timestamp TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

and modify the query to

$query = "insert into auto_parts(id, part, price)
  values(1, 'axle', 200)"
mysql_query($query);

Answer 2

$query = "insert into auto_parts(id, part, price, timestamp)
  values(1, 'axle', 200, 'NOW()')"
mysql_query($query);

Answer 3

Do it in SQL itself instead of passing it ... its more efficient ... This is the corresponding post:
