Why is this table not being dropped?

Need to drop a table. My code looks like this:

$the_twitter_table = "tw_2013-11-06";
$matt = "drop table $the_twitter_table";
$matt_query=mysqli_query($cxn, $matt);
if(!$matt_query)
{
$nuts=mysqli_errno($cxn).': '.mysqli_error($cxn);
die($nuts);
}

The error I get is "1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''tw_2013-11-06'' at line 1"

When I run drop table tw_2013-11-06 in my phpMyAdmin interface, it works great, but I'm blowing it somewhere when I try to do it via PHP. What am I missing?

Put single quotes around the table name.

Instead of this:
$matt = "drop table $the_twitter_table";

Try this:
$matt = "DROP TABLE '$the_twitter_table' ";

Sidebar note: The capitalization is not necessary, but experienced programmers use it to make the SQL commands stand out, and it's often a programming standard in professionally run organizations.  Do whatever you think is right :-)

Use backticks

$matt = "drop table `$the_twitter_table`";

Open in new window

I tried that, Ray, and it still came up short. Same error. What else could it be?

The backticks did it!

Thanks, Gary!

My apologies - I've never even considered putting a hyphen into a table or column name before.  Now that I'm testing this, I'm looking at your message:

1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''tw_2013-11-06'' at line 1

... and wondering why it's different from the message that I get when I run your original query:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-11-06' at line 1 QUERY: DROP TABLE tw_2013-11-06
