am looking for 500 dating site - Updating contact indexes
In last week’s post I discussed the basics of how automatic updates to statistics occur in SQL Server.This week I want to talk about scheduled (aka manual) updates, because as you might remember, we really want to control when statistics are updated.
This command is one you run for a database, not for a specific statistic or index or table.
The sp_updatestats command will only update statistics if data has changed.
Now that you’ve installed Oracle SES, configured it for People Soft application, configured the People Soft application to make use of SES – it is time to deploy the indexes and start making use of the search functionalities.
This is part 4 of the series on People Soft Search Framework and for your reference, the other parts of this topic are mentioned below: Part 1- People Soft Search Framework: How to Install Oracle SES Part 2- How to Configure People Soft 9.2 with Oracle SES Part 3- Configure People Soft to use SES Prior to continuing with the part 4, the following items need to be installed, configured, and functional.
This DMF tracks modifications, and also tells us how many rows were in the table when statistics were last updated, and the date statistics were updated. Sales Order Detail, and then look at the output from the DMF, you can see that the modification counter matches the number of rows I changed* for the Product ID index: USE [Adventure Works2012]; GO UPDATE [Sales].[Sales Order Detail] SET [Product ID] = [Product ID] WHERE [Product ID] IN (921,873,712); GO SELECT [so].[name] [Table Name], [ss].[name] [Statistic Name], [ss].[stats_id] [Statistic ID], [sp].[last_updated] [Last Updated], [sp].[rows] [Rows In Table When Updated], [sp].[rows_sampled] [Rows Sampled], [sp].[modification_counter] [Number Of Modifications] FROM [sys].[stats] [ss] JOIN [sys].[objects] [so] ON [ss].[object_id] = [so].[object_id] CROSS APPLY [sys].[dm_db_stats_properties] ([so].[object_id], [ss].stats_id) [sp] WHERE [so].[name] = N'Sales Order Detail'; GO *You’re correct, I technically didn’t change Product ID to a new value, but SQL Server doesn’t know that.
Also, there’s a foreign key on that column which is why I can’t easily change it a random number.
In SQL Server 2016 you can configure the Rebuild Index task so that it only rebuilds an index if a certain level of fragmentation exists.
Therefore, some of your indexes will rebuild (and thus have statistics updated) and some will not (and not have updated statistics).
Armed with this type of data, we can intelligently decide whether we should update statistics because a percentage of rows (rather than just a fixed number of rows) have changed.
In the example above, only 8% of data changed – probably not enough to require me to update statistics.
How do you manage that with the Update Statistics task?Tags: Adult Dating, affair dating, sex dating
