Suppose that there are 1 billion records on a table, then i execute mysql query in php, something like "UPDATE `table` SET `Field`= 'value' WHERE `Gender`='Male'" but during the execution, the system crashed (server or client) is there a possibility that the half of the records are updated...

im wondering how i could do this idea: td { onclick: some javascript } or div { dooneveryexistence: some javascript } hope that you help me figure this out thanks in advance
