问题 Pretty simple question I suppose, but I can't find the answer on here! I am trying to calculate the volume of records based on a WHERE clause, as well as return a percentage of those records based on the same where clause.

问题 I am using SQL Server 2012 & am creating a table that will have 8 columns, types below datetime varchar(12) varchar(6) varchar(100) float float int datetime Once a day (normally) there will be an upload of approx 10,000 rows of data.

I have read I can use the unique constraint on multiple columns which will guarantee the rows are unique. I think I'm correct in saying

问题 My SQL Server 2012 contains a function Get_Schedule : CREATE FUNCTION Get_Schedule( @pProject_Id AS INT, @pPeriod_Start AS DATETIME2, @pPeriod_End AS DATETIME2) RETURNS TABLE WITH SCHEMABINDING AS RETURN ( SELECT 42 AS Val1, 'Foo' AS Val2); Visual Studio 2015's SQL Server Object Explorer shows the function parameters with the types as defined. However when dragging the function to the strongly typed dataset designer the DATETIME2 parameters are changed to ANSISTRING instead of System.DateTime

Once built, running debug opened a browser window for localhost port 56618, which allowed access from Fiddler to test Http requests. Once I had the project finished, I published it to a website using Web Deploy to

问题 I have recently installed SQL Server 2012 Developer on my laptop. I created a simple SSRS report using AdventureWorks201. The report builds fine but will not deploy.
