Is it possible to make the queries into 1 single query? How to make it

Many thanks for your query, seems we need to group it like Wolfgang's
does.

is there a better way (hopefully simpler) to code this?
i want to get the user id of the logged in user to use in my next statement.
$q1 = sprintf(SELECT uid FROM users WHERE users.username='$username');
$result1 = mysql_query($q1);
$uid = mysql_fetch_array($result1);
$u = $uid['uid'];

You should escape $username before passing it to mysql if its user
submitted data ... sql-injection
one/two liner: but error prone!
$un = mysql_real_escape_string($username);
list($id) = mysql_fetch_row(mysql_query(SELECT uid FROM users WHERE
username='{$un}');
better would be
$result =
little error
-list($id) = mysql_fetch_row(mysql_query(SELECT uid FROM users WHERE
+list($uid) = mysql_fetch_row(mysql_query(SELECT uid FROM users WHERE

You should store the current user id in a session variable. Then you
don't have to hit the database at all.
There really is no short way of doing it. Normally you would create a
function (i.e. runQuery) that you pass the query too. Then it handles
running the query, fetching the data, error

Is your table innodb? If so i think the 'STRICT_TRANS_TABLES' sql_mode 'may' be
causing the problem.
Try inserting the value as

Do you get the same error?

I had already tried that, actually. Produces the same error. I

What sort of data? Is it currently stored in a database? If so, how many
tables?
24GB of text data in a single table is quite a bit, but manageable if
maintained properly.
24 GB of binary data on the other hand, is not very much at all.

given the following table layouts
URLs:
URL_ID (primary key for URL)
URL_TEXT
URL_CATEGORY
URL_ID (key which points to URL.URL_ID)
CATEGORY_ID (key which points to CATEGORY.CATEGORY_ID)
SUBCATEGORY_ID
PK: (URL_ID, CATEGORY_ID)
CATEGORY
CATEGORY_ID (primary Key for Category)
The size of the data is largely irrelevant, it depends on how much of
it you need to use at once. For most setups, 4GB should be more than
enough. A single server is always a bad idea since it's a single point
of failure.
Concurrent users isn't really relevant with the database either since

You could mash it into two lines. Though I think the verbose syntax is more
readable.
mysql_fetch_array( mysql_query(SELECT uid FROM users WHERE
users.username='.mysql_real_escape_string($username).') );
$u = $uid['uid'];
However do you really think that 4 lines is too much to make a

If your table testtab is populated, neither suggestion is efficient.
You could the following instead:
#
# Create an empty table `testtab_copy`
#
1) CREATE TABLE testtab_copy LIKE testtab;
2) Do either of you suggestions:
ALTER TABLE testtab ADD COLUMN c_col char(4) FIRST,ADD COLUMN b_col
