sql-server-2012

问题 I have an ASP.NET MVC3 project that has a database. I want to attach that database to SQL Server Management Studio.

问题 I have a couple of tables (User & UserRecord) in my database that get extremely fragmented (like 99%) and cause the whole database and therefore the website to grind to a halt.

User has around a million rows, UserRecord has around 2.5 million. These tables get written to a lot. They're also being searched a lot. They're both going to get a lot

问题 I have a large data set which for the purpose of this question has 3 fields: Group Identifier From Date To Date On any given row the From Date will always be less than the To Date but within each group the time periods (which are in no particular order) represented by the date pairs could overlap, be contained one within another, or even be identical.

问题 I would like to debug a complex T-SQL script using SSMS 2012. I can run the script in debug mode and place breakpoints, as well as step through my script, but I can't see the values stored in my table variables. In the Locals window I see all these variables, but their value is shown as (table) : There is no way to view the content of the variable through the context menu or by clicking on the variable.
