问题 Q: How would I go about using / applying the row number of each row in a query to a certain column in the entire query? I've added a screenshot to try and make things more obvious: [The picture is only a simple example] I would like to be able to directly use the value of the row number in such a context. (Iterate over the values, somehow?) Thanks in advance. (Sorry if the question is a bit vague) 回答1: Try this : ;WITH TEST AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY id DESC) AS RowNo FROM

问题 I have read many sites, guides, etc; also note I cannot test what I am asking as do not have two computers. Table partitioning simply means that the table is logically divided, such that a particular range is handled by a particular partition only there by reducing load and also allowing parallelism. there is a mention of partitions being on different hard disks but there is never any mention of partitions being on different computers. Is that possible? So for example, data with id<50000 will

问题 The deployment procedures in my company require that SQL scripts for creation of procedures and tables, etc. be bare. Generating create scripts in SQL Server Management Studio gives you significantly more than a bare script, which is unfortunate in this case. For example, for a test table this is what SSMS generated for me: USE [DemoDB] GO /****** Object: Table [dbo].[example] Script Date: 08/07/2012 15:46:32 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[example

问题 Note: I am using SQL Server 2008 R2 and built in LEAD/LAG functions are not available. I need to update a table's column to contain the 'previous' and 'next' values for ProductID - the table needs to store PrevProductID (LAG), ProductID and NextProductID (LEAD). The code below does this very nicely and was adapted from Geri Reshef's answer to http://blog.sqlauthority.com/2011/11/24/sql-server-solution-to-puzzle-simulate-lead-and-lag-without-using-sql-server-2012-analytic-function/ USE

问题 I keep getting an error of Conversion failed when converting date and/or time from character string. This is my vba I am using as well as my sql server stored procedure syntax.

问题 Here's psuedo-code for the stored procedure I currently use, CREATE PROC uspFoo ( @id int, @type nvarchar(255), @status bit output ) AS IF .... SET @status=1 ELSE SET @status=0 GO When executing this stored procedure, I am forced to pass an output parameter that will store its return value, DECLARE @id int, @type nvarchar(255), @status bit SET @id=.. SET @type=.. EXEC uspFoo @id, @assayType, @status output PRINT @status GO The return value, or in this case status , will either be 0 (false) or

问题 I need to change the datatype of a User Defined Data Type (UDDT). I'm using this strategy of renaming the old UDDT and creating a new one with the orignal name. This means that any stored procedures and views will continue to work after they've been refreshed using: EXEC sys.sp_refreshsqlmodule '{objectName}' On columns I still have to call ALTER TABLE ALTER COLUMN and drop and recreate any indexes but it's relatively low-risk and scriptable. The problem I have now is with User Defined Table

问题 I have a console application. I wanna keep watching the changes on a specific column in my database table. I read through internet and I have found that sql dependency is good for my purpose. I started learning about it and I did the following: create a class. In the constructor, I called the static function start and I called a function that has all the sql dependency settings. My problem When I run the application using the start click on visual studio 2013, the apps works and then stops.
