Limit Characters on a PHP MySQL query

I need to limit the amount of characters show on a query. The amount of characters I need to show is 100 from the 'copy' column

Here's my query code:

mysql_select_db($database_Hollybush, $Hollybush);
$query_news = "SELECT id, `date`, title, copy, FROM news ORDER BY id DESC";
$news = mysql_query($query_news, $Hollybush) or die(mysql_error());
$row_news = mysql_fetch_assoc($news);
$totalRows_news = mysql_num_rows($news);

I have tried this but nothing shows?

mysql_select_db($database_Hollybush, $Hollybush);
$query_news = "SELECT id, `date`, title, SUBSTR(copy,50,50) FROM news ORDER BY id DESC";
$news = mysql_query($query_news, $Hollybush) or die(mysql_error());
$row_news = mysql_fetch_assoc($news);
$totalRows_news = mysql_num_rows($news);

Anyone know how to do this?

Try this:

"SELECT id, `date`, title, LEFT(copy,100) FROM news ORDER BY id DESC";

Thanks for that.

It doesn't show any result i'm afraid.

The text shows with the first of my two codes above by the way so everything else is ok.

That is strange since the first statement contains a syntax error (improper comma between "copy" and "from):

   "SELECT id, `date`, title, copy, FROM news ORDER BY id DESC";

What is the type of that copy column, ie. how did you create it?

HI,

Yes, you're right, I actually deleted that comma after posting.

I created it in MySQL as text (see screenshots) MySQLScreen-shot-2011-02-22-at-19.14..png

I tried to simulate it on my MySQL instance:

   drop table test;
   create table test (a int, copy text);
   insert into test values (1, 'abcde fghij klmno');
   select a,copy from test;
   select a, left(copy,5) from test;

The first select returns:

  1, abcde fghij klmno

and the second:

  1, abcde

just like expected.

By "no results" do you mean the column selected as left(copy,100) is empty but other colums show right or that there are no rows returned at all?

You could also try:

"SELECT id, `date`, title, LEFT(copy,100) as copy FROM news ORDER BY id DESC";
