After installing the necessary development tools and the MySQL database (see Install essential development utilities) it is time for at quick test to see if everything works.

Test Database

In PHPMyAdmin create a new database called test

Create a new table in the test database. Create 3 fields. The fields shall be named:


The id field shall be set to

type int 
10 in length
unsigned attribute
Not Null

Insert a couple of fields into the table.

Create a test user

Create - in Privileges - a new user with localhost as the host.

Hit the Go button.

Use the edit button at the end of the line with the name to be edited in this view:


then click the Check ALL in the following


and finally the Go button to save the privileges.

Test From C

Using Eclipse there are a couple of settings, that needs to be ensured.

In the project settings ensure that you have the correct paths for the compiler to search for include files (Notice these settings are for a C++ project - they are similar for C):


and the correct paths to the libraries:


Enter the source below in a .c-file or .cpp-file:

	char *user = "klausk";
	char *password = "pingeling";

	conn = mysql_init(NULL);
	/* Connect to database */
	if ( ! mysql_real_connect(conn, server, user, password, database, 0, NULL, 0))
		fprintf(stderr, "%s\n", mysql_error(conn));
	/* send SQL query */
	if (mysql_query(conn, "show tables"))
		fprintf(stderr, "%s\n", mysql_error(conn));
	/* Tell database that we're going to use the result */
	res = mysql_use_result(conn);
	/* output table name */
	printf("MySQL Tables in mysql database:\n");
	while ((row = mysql_fetch_row(res)) != NULL)
		printf("%s \n", row[0]);
	/* Tell database that we wont be needing this result anymore */
	/* Prepare a new query */
	if (mysql_query(conn, "SELECT * FROM tstTab"))
		fprintf(stderr, "%s\n", mysql_error(conn));
	} else
		res = mysql_use_result(conn);
		printf("\n\ntstTab contains:\n");
		while ((row = mysql_fetch_row(res)) != NULL)
			printf("id: %s, name %s, place: %s  \n", row[0], row[1], row[2]);
		/* Tell database that we wont be needing this result anymore */
	return 0;

Be sure to change the USERNAME and PASSWORD to a valid user on the database server.
