How to Connect MySQL Database Using C

Connecting to a MySQL database from a C application allows you to perform database operations, such as executing SQL queries. Here's a guide on how to do it:

Prerequisites:

• Install the MySQL Connector/C libraries.

Steps:

1. Include Necessary Headers:

   #include 
   #include 
   #include 
   #include 

2. Create a Connection:

   sql::Driver *driver = get_driver_instance();
   sql::Connection *con = driver->connect("tcp://127.0.0.1:3306", "root", "root");

3. Set the Database:

   con->setSchema("your_database_name");

4. Create a Statement and Query:

   sql::Statement *stmt = con->createStatement();
   sql::ResultSet *res = stmt->executeQuery("your_sql_query");

5. Iterate Over Results:

   while (res->next()) {
     cout getString("column_name") 

Here's an example that demonstrates how to execute a simple "Hello World!" query:

int main() {
  sql::Connection *con;
  sql::Statement *stmt;
  sql::ResultSet *res;

  try {
    con = get_driver_instance()->connect(
        "tcp://127.0.0.1:3306", "user", "password");
    con->setSchema("test");

    stmt = con->createStatement();
    res = stmt->executeQuery("SELECT 'Hello World!' AS _message");

    while (res->next()) {
      cout getString("_message") 
By following these steps, you can connect to a MySQL database and execute SQL queries using C  .
