How to Connect to a MySQL Database Using C ?

Connecting to Your MySQL Database Using C

To establish a connection to your MySQL database and perform queries, C offers a comprehensive solution. Let's explore how you can achieve this task efficiently.

Required Libraries

Begin by incorporating the necessary libraries into your C project:

• mysql_connection.h: Provides the fundamental connection interface
• cppconn/driver.h: Facilitates interaction with the MySQL driver
• cppconn/exception.h: Enables handling of exceptions that may arise during database operations
• cppconn/resultset.h: Allows for retrieving and iterating over results
• cppconn/statement.h: Enables creating and executing SQL statements

Example Code

The following sample code demonstrates how to establish a connection, execute a query, and retrieve results from a MySQL database:

<code class="c++">#include <stdlib.h>
#include <iostream>

#include "mysql_connection.h"

#include <cppconn>
#include <cppconn>
#include <cppconn>
#include <cppconn>

using namespace std;

int main() {
  try {
    // Create the necessary objects
    sql::Driver *driver;
    sql::Connection *con;
    sql::Statement *stmt;
    sql::ResultSet *res;

    // Establish a connection
    driver = get_driver_instance();
    con = driver->connect("tcp://127.0.0.1:3306", "root", "root");

    // Set the default schema
    con->setSchema("test");

    // Create a statement object
    stmt = con->createStatement();

    // Execute a query
    res = stmt->executeQuery("SELECT 'Hello World!' AS _message"); // Replace with your statement

    // Iterate over the results
    while (res->next()) {
      cout getString("_message") getString(1) <p><strong>Conclusion</strong></p>
<p>By following the steps and incorporating the provided code example, you can successfully connect to your MySQL database from C  , execute queries, and retrieve the desired results. This enables you to develop robust and efficient database-driven applications.</p></cppconn></cppconn></cppconn></cppconn></iostream></stdlib.h></code>
