问题 I have a table called countries and I define the country_name column to be unique by creating a “Index/Key” of type “Unique Key” on SQL Server 2008 R2. But I have the following questions: will creating “Index/Key” of type “Unique Key” automatically create a non-clustered index on this column? if I change the type from being “Unique Key” to "Index" and I keep the IsUnique value to be "Yes",, then will there be any differences ? so why there are two options “Unique Key” and "Index" I think the

问题 I was just reading this SO thread and had a question for @Mack regarding whether there is a way to check if a SQL object is referenced by any other SQL objects. He (@Mack) used T-SQL and DMVs to accomplish something similar in his answer. Is this possible, if so how? I would have posted this as a comment, but I don't have sufficient reputation yet... 回答1: You can, but not with a DMV instead you'll need a related dynamic management function (DMF) dm_sql_referencing_entities (more info here).

问题 I'm copying data from SQL to text file using bcp tool with following command: bcp.exe "exec <StoredProcedure>" queryout "temp.txt" -T -r\n -c This command runs as expected on test environment and creates/updates required file without additional prompts.

Any ideas why is this happening? Based on bcp

And I was wondering if there is a way to simplify this. Here's my query DECLARE @DATE DATE SET @DATE ='2013-09-13' IF DATENAME(DW,@DATE) = 'SUNDAY' BEGIN SELECT DATEADD(DAY,-1,@DATE) AS DATE, 'IS THE NEAREST SATURDAY' END ELSE IF DATENAME(DW,@DATE) = 'MONDAY' BEGIN SELECT DATEADD(DAY,-2,@DATE) AS DATE, 'IS

问题 Question What is the benefit of applying locks to the below statement? Similarly, what issue would we see if we didn't include these hints? i.e. Do they prevent a race condition, improve performance, or maybe something else? Asking as perhaps they're included to prevent some issue I've not considered rather than the race condition I'd assumed. NB: This is an overflow from a question asked here: SQL Threadsafe UPDATE TOP 1 for FIFO Queue The Statement In Question WITH nextRecordToProcess AS (
