Connecting MySQL with C++ on Linux

MySQL API ..
The C API code to connect mysql on unix ( linux ) is being distributed with MySQL. It is the part of mysqlclient library and allows C programs to access a database.

Following packages needs to be compiled to access mysql from C/C++ on unix.

* mysql: MySQL client programs and shared library
* mysqlclient: Backlevel MySQL shared libraries (old libs)
* mysql-devel: Files for development of MySQL applications (a must have)
* mysql-server: Mysql server itself
* gcc, make and other development libs: GNU C compiler


How do I compile and link program against MySQL libs?

$ mysql_config --libs
$ mysql_config --cflags

$ gcc -o output-file $(mysql_config --cflags) mysql-c-api.c $(mysql_config --libs)

$ ./output-file

Sample Program

/* Simple C program that connects to MySQL Database server*/
#include
#include

main() {
MYSQL *conn;
MYSQL_RES *res;
MYSQL_ROW row;

char *server = "localhost";
char *user = "root";
char *password = "PASSWORD"; /* set me first */
char *database = "mysql";

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));
exit(1);
}

/* send SQL query */
if (mysql_query(conn, "show tables")) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}

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]);

/* close connection */
mysql_free_result(res);
mysql_close(conn);
}
