php - mysql LOCK TABLE - no "commit" of data until UNLOCK -
i have curious problem - have php (5.5.9) script writes mysql (5.6.27) database. pseudocode looks this:
lock table write, b write, ... , c write; -- inserts/updates unlock tables;
if script runs fine. if stop script half-way operations performed not committed (i not using transactions).
i baffled, thought there no transaction-like logic when comes lock, no other sessions able access tables. can please me understand going on under hood prevent data being persisted in scenario?
thank :)
