It is a multi user, multithreaded database management system. MySQL is especially popular on the web. It is one part of the very popular LAMP platform consisting of Linux, Apache, MySQL, and PHP. MySQL database is available on most important OS platforms.
It runs on BSD Unix, Linux, Windows, or Mac OS. To be able to compile C examples, we need to install the MySQL C development libraries. The above line shows how we can do it on Debian based Linux. For Windows users, the Pelles C IDE is highly recommended. In C99, we can mix declarations with code. In older C programs, we would need to separate this line into two lines. This code line outputs the version of the MySQL client.
Here is how we compile the code example. We provide connection handler, host name, user name and password parameters to the function. The other four parameters are the database name, port number, unix socket and finally the client flag. In our case, the statement creates a new database. Finally, we close the database connection.
This is the proof that the database was created. We have created a new user user12. Here we grant all priviliges to user12 on testdb database. The next code example will create a table and insert some data into it. The fifth parameter is the database name. Here we create a table named Cars.
We insert one row into the Cars table. We show tables in the database. We select all data from the table. We execute the query that will retrieve all data from the Cars table.
