Question

Each and every SQL query I issue to my MySQL server creates a new (increments) CONNECTION_ID(). This happens both on my local as well as on my shared remote server.

Is this the reason behind LAST_INSERT_ID() and ROW_COUNT() resulting in 0? How to address this issue?

Originally in MySQL: LAST_INSERT_ID() returns 0

Answer 1

By default, PersistentConnections are disabled in phpMyAdmin.

Is this the reason behind LAST_INSERT_ID() and ROW_COUNT() resulting in 0?

Yes.

How to address this issue?

Enable persistent connections:

$cfg['PersistentConnections'] = TRUE;
