Please help me. Doesn’t it mean that when the exclusive lock does not commit the transaction, this data cannot be queried in other places? Why does it have no effect? ​​I opened two query editor windows and both are Same code, no transaction is submitted after the first query, why can the other query still be performed? Shouldn’t the exclusive lock be blocked from other queries when the first transaction is not submitted? I don’t understand. I followed the video I practiced in the tutorial, but the video tutorial shows that the exclusive lock is effective, but mine is not effective, please help! !

START TRANSACTION

SELECT * from `article` where id = 2 for update;

COMMIT
