问题 I have a table with id, play, starttime and endtime. I want to find the total play time per day. I think the query will be similar as the following but I am sure it is not right. It will be also very convenient if i get 0 when no game is played but if it is difficult I dont mind. Select id, play, date, CASE WHEN datediff(day, starttime, endtime) = 0 then sum(totaltime) END as TimePerDay from cte where starttime >= '2015-05-30 17:11:34.000' group by id, playtime, starttime, endtime I am

问题 Using the following screenshot to show an example of the data set, int,datetime2,datetime2, int How can i return all the free periods of time which are available within the start and stop ranges which are also equal or longer than the slot duration parameter when they are not stored in the database as appointments declare @startRange datetime2 declare @endRange datetime2 declare @slotDurationInMinutes int set @startRange = '2016-06-06T22:00:00.000Z' set @endRange = '2016-06-07T21:59:00.000Z'

问题 This code works fine and does exactly what I want, which is to sum the Qty * Price for each instance of the dynamic query. But when I add an IIF statement it breaks. What I am trying to do is the same thing as above but when the transaction type is 'CO' set the sum to a negative amount. 回答1: The problem turned out to be the NVARCHAR(4000) type of @sql , limiting its length to 4000 characters: the query got truncated at some random place after adding another long chunk to it. DECLARE @sql

问题 I am having trouble succinctly describing what I need, so any help editing the title is appreciated!

DepartmentIDs that aren't in the JobsDetail records for the Job will show a NULL value in the Job column. With one Jobs record, a typical LEFT

问题 So, I've been hunting for a solution for this for awhile and have come up with what sort of works ... but I can't help feeling that there must be something more elegant. What I'm looking for is to be able to extract existing data from a populated database & incorporate that data into loading scripts.

问题 I’m working with a SQL stored procedure that makes a call to xp_cmdshell. xp_cmdshell has been enabled, and has a proxy account set to ‘vpexporter’. This sproc was designed to write out a data file to disk. This sproc had been working when it was on a SQL 2005 server. The environment has been upgraded to SQL 2012 and the sproc no longer runs. The line making the call is: set @sql1 = 'bcp "SELECT * FROM dbo.udPayrollOutput" queryout "D:\Repository\Exports\' + @fileunique -Uvpexporter

问题 We are trying to include in our SQL only those rows where the next row is within 12 hours, based on a timestamp. Along with this, we also need to rank the rows in order to identify initial contact followed by the number of contacts within the time frame. Unfortunately we cannot just look for min() max() within 12 hours as the date range can be longer (months) but the time between contacts can only be 12 hours. A person may have multiple contacts within the over all date range, and the initial
