    <p>Guys i'm facing a problem with this code, the problem is the timeout by timeout i mean the </p> <p>time it takes the program to tell me if the server is connected or not. If i use my </p> <p>localhost i get the answer fast, but when i connect to outside my localhost it takes 50sc - </p> <p>1.5 min to response and the program frezz until it done. HOw can i fix the frezzing, or make </p> <p>my own timeout, like if still waiting after 50sc, tell me connection failed and stop?</p> <p>please use codes as help, becouse i would understand it better, thanks for any help i get</p> <p>PS: USING MAC</p> <pre><code>#include "mysql.h" #include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; // Other Linker Flags: -lmysqlclient -lm -lz // just going to input the general details and not the port numbers struct connection_details { char *server; char *user; char *password; char *database; }; MYSQL* mysql_connection_setup(struct connection_details mysql_details) { // first of all create a mysql instance and initialize the variables within MYSQL *connection = mysql_init(NULL); // connect to the database with the details attached. if (!mysql_real_connect(connection,mysql_details.server, mysql_details.user, mysql_details.password, mysql_details.database, 0, NULL, 0)) { printf("Conection error : %s\n", mysql_error(connection)); exit(1); } return connection; } MYSQL_RES* mysql_perform_query(MYSQL *connection, char *sql_query) { // send the query to the database if (mysql_query(connection, sql_query)) { printf("MySQL query error : %s\n", mysql_error(connection)); exit(1); } return mysql_use_result(connection); } int main() { MYSQL *conn; // the connection MYSQL_RES *res; // the results MYSQL_ROW row; // the results row (line by line) struct connection_details mysqlD; mysqlD.server = (char*)"Localhost"; // where the mysql database is mysqlD.user = (char*)"root"; // the root user of mysql mysqlD.password = (char*)"123456"; // the password of the root user in mysql mysqlD.database = (char*)"test"; // the databse to pick // connect to the mysql database conn = mysql_connection_setup(mysqlD); // assign the results return to the MYSQL_RES pointer res = mysql_perform_query(conn, (char*) "SELECT * FROM me"); printf("MySQL Tables in mysql database:\n"); while ((row = mysql_fetch_row(res)) !=NULL) printf("%s - %s\n", row[0], row[1], row[2]); // &lt;-- Rows /* clean up the database result set */ mysql_free_result(res); /* clean up the database link */ mysql_close(conn); return 0; } </code></pre>

    1. COThe timeouts are within the TCP stack - you can probably do something to adjust them, but not until you tell your platform.

    3. COAre you sure that you change the basics of your code when you implement it outside the localhost? `mysqlD.server = (char*)"Localhost";` doesn't make sense in a non-localhost server Moreover, does it connect when you implement it in another host? I mean that you said it freezes for sometime, but does it connect?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
