Sqlserver transaction and lock problem
2022-04-23 14:50:00 【CSDN Q & A】
Excuse me, , If two things change or read a row of data at the same time , What will the lock of the first transaction do to the second transaction ? End or pause ?
Take the answer :
1、 Data was being updated during a transaction , Other transactions cannot be modified , You can only modify after the last transaction is completed , But it does not affect the reading of data ;
2、 There must be a sequence of transactions , Even if you click two at the same time, execute them together ;
