SQL Connection Strings: Setup, Examples, and Configuration
SQL connection strings are a sequence of variables that define how your application connects to a specific MySQL database. This connection allows your code to communicate directly with your MySQL environment.
If you do not have a database created yet, the following article will provide the correct instructions:
Configuration for MySQL Connection
Once you have your database set up, create the database tables through phpMyAdmin, MySQL software, or an online PHP/Perl script. These settings are required when building your MySQL connection string:
- Version: MySQL 8.0
- Username: cpUsername_dbName
- Database Name: cpUsername_dbUsername
- Password: the password for cpUsername_dbUsername
- Hostaddress: localhost
- Port: 3306
These details must be included in your SQL connection string to establish a successful connection.
SQL Connection String Examples
Use either of the following MySQL connection string examples, making sure to replace variables in red with your actual database information.
For Perl:
$dbh = DBI->connect("DBI:mysql:cpuser_db:localhost","cpuser_dbuser","password");DBI->connect("DBI:mysql:cpUsername_dbNamelocalhost","cpUsername_dbUsername","password");
For PHP:
$dbh=mysql_connect ("localhost", "cpuser_dbuser", "password") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("cpuser_db");
