Record Locking using Connectors

How can I handle record locking (MYSQL) using connectors?
I am relatively new at handling record locking with SQL, so any direction would be helpful.

I want to only allow one user at a time to modify a record. I am using PHP/MYSQL and of course DHTMLX.
Is there something in dhtmlxForm that handles this??
Thank you.

Not quite sure, but you can try to use transactions. ( It is not exactly the same as locking, but can be used for the same purpose ) … r:security
