Ok, I'm new to php and MYSQL aswell. I have a couple programs actually that are getting this error and I don't see what could be causing this at all.

Here's the situation. I have a job interview page. The user enters the information from the candidate and submits the interview. Everything works find the FIRST time around. Database is created, table is created, ID is given to the candidate, everything works good.

When I go to enter a second interview I get this error:
Unable to execute the query.

Error code 1007: Can't create database 'jobinterview'; database exists

Here's the code that creates the database, tables etc.

I know it may seem a bit messy towards the end, still working on getting it tightened up and buttoned up a bit, but I'm at my wits end with this error and have looked through book after book, and searched the web and can't find a solution. Thanks for the help.

I'm currently using WAMP and have ran it through phpMyAdmin as well as trying to run it through SQLyog, same results. If that helps at all. Also, replaced my user name and password with "user" and "password" just in case.

Try this:

/* ==== Code to create hit_counter database if it does not already exist ==== */
$DBName = "jobinterview";
$SQLstring = "CREATE DATABASE IF NT EXISTS $DBName";
$QueryResult = @mysqli_query($DBConnect, $SQLstring)
		OR die("<p>Unable to execute the query.</p>"
		. "<p>Error code " . mysqli_errno($DBConnect)
		. ": " . mysqli_error($DBConnect)) . "</p>";
mysqli_select_db($DBConnect, $DBName);

Get a new error there.

Unable to execute the query.

Error code 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 'NT EXISTS jobinterview' at line 1

Sorry, should have said "NOT EXISTS..."

Ok, that worked. Thank you very much.
Are you able to explain why the other code wasn't working correctly?

The book I'm going through to learn this has the code I had in every single program they use as an example, and every single one of them won't work throwing up the 1007 error, and needless to say it's frustrating trying to learn from a book that is wrong.

Also, when I put the 2nd , 3rd interview etc in, shouldn't the "successfully created database" echo statement not be showing?

I tried putting and if..else statement in there but even with that it keeps doing it.

Gonna mark this as solved. I figured out what was going on, and again sometimes even the smallest of things can slip by. I rewrote that code literally 20 times and not once did I pick up what I was doing.

In this line:

if (!@mysqli_select_db($DBConnect, $DBname)) {

for $DBName I have a (n) instead of an (N). Unreal but it works now. Gonna mark it as saved and thanks again for the help. I just can't believe the amount of time I rewrote that code and made the same exact mistake that many times and didn't catch it.
