I wrote a stored procedure yesterday and used select to retrieve data. However, the instructor missed some data and the SQL statement was completely correct. Some data was lost, so I was puzzled. Later, at the guidance of a master, some data in the database contains invisible tabs. It is precisely because of these tabs that the SELECT statement cannot retrieve the correct records. After the database is updated, the problem is solved. Problem: The SEL

Label: What do you feel if you have more than 10 indexes on a single table? Obviously, it will slow down the rate of increase, deletion and change. Don't expect developers to be able to build indexes. My approach is to monitor a very long period of time first. See which indexes are not practical to, and then delete.But after deletion, suppose to find a day practical, and then again built, assuming that the big table. That's a bit of a problem.
