<div dir="ltr"><div><div><div><div><div><div><div>hello<br><br></div>i have a web page that refreshes all the time to display things from a mysql database which is updated from time to time.<br></div>however. this meens a lot of un-needed acesses to the database. and this refresshing page may be openede by many browsers. causing a huge load on the database.<br>
<br></div>i know mysql supports triggers, but it seems this is only internal (i.e. trigger may do a query, usually an "update" query, but this is not what i need).<br><br>I am looking for a way to leave the connection open with mysql, not sending any queries, just waiting for mysql to notify me when a somthing changes.<br>
<br></div>does mysql support that ?<br></div>examples of doing that will be nice<br><br><br></div>thanks,<br></div>erez.<br></div>
