问题 For a notification project, would like to push event notifications out. These are things like login, change in profile, etc., and to be displayed to the appropriate client. I would like to discuss some ideas on putting it together, and get some advice on the best approach. I noticed here that changes made to a CouchDB can be detected with a _changes stream, picked up by Node, and a process kicks off.

问题 I need to check when function was changed last time. I know how to check creation date (it is in function properties window in SQL Server Management Studio). I found that in SQL Server 2000 it wasn't possible to check modify date ( look at this post: Is it possible to determine when a stored procedure was last modified in SQL Server 2000?) Is it possible to check it in SQL Server 2008? Does MS add some new feature in system tables that allow to check it? 回答1: SELECT name, create_date, modify

问题 We have a few huge databases (20GB+) which mostly contain static lookup data. Because our application executes joins against tables in these databases, they have to be part of each developers local SQL Server (i.e. they can't be hosted on a central, shared database server). We plan on copying a canonical set of the actual SQL Server database files (*.mdf and *.ldf) and attach them to each developer's local database. What's the best way to find out the local SQL Server instance's data

问题 I have a development database that re-deploy frequently from a Visual Studio Database project (via a TFS Auto Build). Sometimes when I run my build I get this error: ALTER DATABASE failed because a lock could not be placed on database 'MyDB'. Try again later. ALTER DATABASE statement failed.

问题 TSQL MSSQL 2008r2 I'm re-writing the question to try and make it clear what the issue is that I'm trying to explain. I've got a stored proc that takes 3 parameters. VehicleKey, StartDate and EndDateTime. I'm querying a Data Warehouse db. So the data shouldn't change.

I'm querying a Data WH so the data doesn't

问题 I know this question is asked frequently here but I have some different requirements. I want to get this output. I am getting this also with my logic but can this can be done in more simple and optimised way. To run this query faster. Here is my query: select ISNULL('PortFolio Code: '+a.CPORTFOLIOCODE,'Grand Total') as [PortFolio Code], COUNT(SZCUSTOMERNO) as [Accounts], CAST(COUNT(SZCUSTOMERNO) * 100 / (Select COUNT(SZCUSTOMERNO) from dbo.COL_TRN_AGREEMENT) as nvarchar(50))+' %' as [%], sum
