wpdb add temporary while drop table

The code snippet below demonstrates how to add a temporary table using the wpdb class in the C programming language:

#include <stdio.h>
#include <stdlib.h>
#include <mysql.h>

int main() {
    MYSQL *conn;
    char *server = "localhost";
    char *user = "root";
    char *password = "password";
    char *database = "mydatabase";

    conn = mysql_init(NULL);

    if (!mysql_real_connect(conn, server, user, password, database, 0, NULL, 0)) {
        fprintf(stderr, "%s\n", mysql_error(conn));
        exit(1);
    }

    if (mysql_query(conn, "CREATE TEMPORARY TABLE temp_table (id INT, name VARCHAR(50))")) {
        fprintf(stderr, "%s\n", mysql_error(conn));
        exit(1);
    }

    printf("Temporary table created successfully.\n");

    mysql_close(conn);

    return 0;
}

Explanation: 1. The code begins by including the necessary header files for standard input/output, memory allocation, and the MySQL library. 2. The main() function is defined as the entry point of the program. 3. A MYSQL pointer conn is declared to establish a connection with the MySQL database. 4. Strings server, user, password, and database are initialized with the respective connection details. 5. The mysql_init() function is called to initialize the connection object conn. 6. The mysql_real_connect() function is used to establish a connection to the MySQL server using the provided connection details. 7. If the connection fails, an error message is printed to the standard error stream and the program exits. 8. The mysql_query() function is used to execute the SQL statement to create a temporary table named temp_table with two columns: id of type INT and name of type VARCHAR(50). 9. If the query execution fails, an error message is printed to the standard error stream and the program exits. 10. If the table is successfully created, a success message is printed to the standard output. 11. The mysql_close() function is called to close the database connection. 12. The program terminates by returning 0 to indicate successful execution.
