How To Get MySQL Statement Execution Errors in MySQL?
✍: FYIcenter.com
When you execute a MySQL statement with mysql_query(), and the statement failed, mysql_query() will return the Boolean value FALSE. This is good enough to tell that there is something wrong with that statement. But if you want to know more about the cause of the failure, you can use mysql_errno() and mysql_error() get the error number and error message. The tutorial exercise below shows you an improved version of the previous PHP script:
<?php $con = mysql_connect('localhost:8888', 'guest', 'pub'); $sql = 'CREATE DATABASE fyicenter'; if (mysql_query($sql, $con)) { print("Database fyicenter created.\n"); } else { print("Database creation failed with error:\n"); print(mysql_errno($con).": ".mysql_error($con)."\n"); } mysql_close($con); ?>
If you run this script, you will get something like this:
Database creation failed with error: 1044: Access denied for user 'guest'@'%' to database 'fyicenter'

⇐ Failed to Create a Database in MySQL
