MySql – Insert
Inserting rows into MySql can be done in a couple of ways. You can use the INSERT…VALUES and INSERT…SET commands.
MySql is the worlds second most popular database engine (July 2013) and its open source. It is based on SQL (Sequential Query Language). Unlike MS Access it does not run as a stand-alone application. It runs as a background service on a computer (typically called ‘a server’) and you connect to it using a username and password. Once you have connected to the MySql server you can query it using SQL or Structured Query Language. The server will respond with the results of your query.
MySql – Feedback
Getting helpful feedback from MySQL when it errors is possible if you use the following:
mysql_query($sql) or die('Some useful message:' . mysql_error() );
MySql – Relationships
Dealing with relationships in MySql is not as straightforward as either MS Access or as you would have hoped for. Creating simple primary keys isn’t too difficult
MySql – Select
To grab a bunch of data from an SQL database you need to write a SELECT query.
MySql – Connections
Connecting to the MySql database via PHP is done through the CONNECT functions.
