问题 I have to expoet my DB into a bacpac file to import it into Azure. When I try to export I get an error because any indexes have a fillFactor value. I've found how to set a fillFactor value for all indexes but I can't specify 0, the value have to be between 1 an 100. If I change the value in the management studio I can set it to 0. The problem is that I have got lots of indexes to change and I would like to change the fillFactor value to all of them trough tsql. Any ideas?. Thanks. 回答1: This

问题 Usually when I'm creating indexes on tables, I generally guess what the Fill Factor should be based on an educated guess of how the table will be used (many reads or many writes). Is there a more scientific way to determine a more accurate Fill Factor value? 回答1: You could try running a big list of realistic operations and looking at IO queues for the different actions. There are a lot of variables that govern it, such as the size of each row and the number of writes vs reads. Basically: high

How do you specify the Fill Factor when creating an index in MySql? You don't. http://dev.mysql.com/doc/refman/5.0/en/create-index.html However, it is an 'accepted' feature request for version 6.x: http://bugs.mysql.com/bug.php?id=18178 So, don't hold your breath on seeing it any time soon. Assuming that you are using InnoDB, it seems like this is only supported at database level, not index level. The setting is called innodb_fill_factor and defaults to 100 see https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_fill_factor for more details. 来源: https://stackoverflow

Though it does generate a pure T-SQL solution that you can apply to

However it's not quite that simple, as almost all writes

How to find out SQL Server table's read/write statistics?

问题 Is there a way to find a statistics on table read and write count on SQL Server 2005/2008 ? I am specifically looking for DMVs/DMFs without using triggers or audits. The goal here is to find out appropriate fill factor for indexes - got an idea from this article (Fill Factor Defined). [UPDATE] There is a follow up question on ServerFault How to determine Read/Write intensive table from DMV/DMF statistics 回答1: sys.dm_db_index_physical_stats (size and fragmentation) sys.dm_db_index_usage_stats
