mySQL datetime field default now() fails

I have a mySQL database table with a column field datatype of datetime that
I set up in the original create table statement like this:

create table nnet_usermetada ta (
....
nnet_record_ent ered datetime default 'now()'
)

However, upon execution, each time a record is entered into
nnet_usermetada ta the results are:

00-00-0000 00:00:00

Is there a way I can always ensure that the current date and time are always
entered into the datetime field?

Hi Phil,

Why not using a timestamp? It is updated every time the record is updated.

nnet_record_ent ered timestamp(14) NOT NULL

You could declare that column as TIMESTAMP. Then, when you insert NULL
value in it, it will insert the current date and time.
The format is a little different, instead pf 05-05-2003 17:15:13 it
will be 20030505171513.
If you wish to keep the DATETIME declaration, you could let the
application calculate the current date/time and then insert the
achieved value.

I am fairly new to SQL so sorry if this is a really dumb question. I have a small (still) SQL database, which I am trying to query from an ASP page. The field I am querying is of DATETIME data type, and is populated automatically using the GetDate() function as a default value. When I try and search on this field, using a date/time in the format dd/mm/yyyy hh:mm:ss as the search criteria, it fails with the following

So I need to load lots of data into my database. So I discover LOAD DATA INFILE. Great! This little gem loads my CSV in blazing times (compared to parsing the file and doing INSERT for each row). Its still slow on large files, but just barely acceptable. Only one problem. It truncates fields to 256 characters, even on a text field.

You may be wondering why you would want to put your files “into” the database, rather than just onto the file-system. Well, most of the time, you wouldn’t. In situations where your PHP application needs to store entire files, the preferred method is to save the file onto the server’s file-system, and store the physical location of the file in your database. This is generally considered to be the easiest and fastest way to store files. ...
