Here are some examples:
// Extablish a tcp connection with the SQL database
int connectSQL()
{
MYSQL *tmp;
tmp = mysql_connect(&sqlHandle, SQL_HOST, SQL_USER, SQL_PASS);
if (tmp == NULL)
return 0; // failed to establish connection with the SQL server
return (!mysql_select_db(&sqlHandle, SQL_DB));
}
// below are for queries
sprintf(query_string,
"INSERT INTO tran_request VALUES(\'%16s\', \'%20s\', \'%8s\', \'%1s\',
\'%4s\', \'%20s\', \
\'%4s\', \'%12s\', SYSDATE())", \
TxnReference, login, ClientID, TransactionType, AccountNumber, \
CardData, CardExpiryDate, TotalAmount);
query = mysql_query(&sqlHandle, query_string);
if (query) {
error(query_string, NO_EXIT);
error("Error when updating the database for transaction
request, \
see above query string for deails", EXIT);
}
// using the fetched queries
sqlResult = mysql_store_result(&sqlHandle);
sqlRow = mysql_fetch_row(sqlResult);
mysql_free_result(sqlResult);
if (*sqlRow == NULL)
blah and so on....
Hope this helps...
Shao.
