We now have a lot of developers have a bad habit, for convenience, put a lot of key information in global variables, such as user name, password, mailbox and so on. The fact that data is not in the right scope poses a serious security problem, for example, we can use the following

A serious risk of mysql using both orderby and limit queries-data loss I often use order by and limit to display and sort data by PAGE, and I have never found any problems. However, there was a serious problem during the past two days. When the data was read in ascending order by timestamp and in batches by limit, some records were lost, the records clearly in the table cannot be read. After studying it for a long time, I finally found out the problem

); thus, all are blocked.Another possible risk is that the tables_to_lock linked list of the Relay_log_info class stores the table to be locked by the Slave. If the Slave cannot continue in time, the tables_to_lock linked list cannot be cleared in time, which may cause many lock problems, it may cause large-scale blocking. The last time there was a fault, MySQL Hang died, it is likely that we skipped the copy error script show slave status and slave s

limit to read data in batches, such as:select id, pay_time from order_customer_new where flag=0 order by pay_time asc, id asc limit 250, 10;Discover problemsIn the process of reading the data, it is found that there is a time stamp equal to the record, two times read out, you may lose a record. See, Id=465 's record is lost. Problem analysis and speculationWhen the sorted values are equal, their sequence is indeterminate. Here I guess: when 465 and 466 are at the end of limit 466 is in front,
