This article mainly introduces "the solution to optimize table error". In the daily operation, I believe that many people have doubts about the solution to optimize table error. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt about "optimize table error solution"! Next, please follow the editor to study!

The code is as follows:

ALTER TABLE table.name ENGINE='InnoDB'

This will create a copy of the original table, and drop the original table, and replace to the original place.

Although this is safe, but I suggest you do backup and test first before doing this.

I see. It roughly means that innodb's database does not support optimize, so you can use the

ALTER TABLE table.name ENGINE='InnoDB'

This method creates a new table by copying the old table, and then deletes the old table. Although this process is safe, it is better to make a backup first when doing the operation.

There is another way:

You can make OPTIMIZE TABLE work on other storage engines by starting mysqld with the-skip-new or-safe-mode option. In this case, OPTIMIZE TABLE is just mapped toALTER TABLE.

It means that we are required to specify the-- skip-new or-- safe-mode option at startup to support the optimize function.

At this point, the study of "the solution to optimize table error" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
