How to pivot without knowing fixed columns in T-SQL

由 本小妞迷上赌 提交于 2020-04-05 05:13:22
问题 I have a table called balance which I wish to pivot, however it is quite difficult since the column names would be labelled 1,2,3 and balances would be sorted by descending order per customer. This is screenshot of current table: And the pivot table: I reviewed other videos and post but I didn't find a solution to match my current situation what I want to achieve. So the final results would be the customer would be sorted by asc and balances would be sorted by desc. So for customer 3 the

由 孤者浪人 提交于 2020-03-05 03:08:12
问题 I created a request with SSMS: SELECT CONCAT(LastName,' ', FirstName) AS [Nom du vendeur], SalesPersonID, DATEPART(YYYY, [OrderDate]) AS [Annee], FORMAT(SUM(soh.SubTotal), '#,#00.') AS [Ventes] FROM Sales.SalesOrderHeader AS soh INNER JOIN Person.Person AS pp ON soh.SalesPersonID = pp.BusinessEntityID WHERE pp.PersonType = 'SP' AND soh.OnlineOrderFlag = '0' AND OrderDate NOT BETWEEN CONVERT(DATETIME, '01/01/2011', 101) AND CONVERT(DATETIME, '12/31/2011', 101) GROUP BY SubTotal, OrderDate,

Use “Attach” as an Upsert in Entity Framework Core

由 房东的猫 提交于 2020-03-03 08:04:00
问题 According to oneunicorn, DbSet.Attach puts all entities in the graph into the Unchanged state. However, entities will be put in the Added state if they have store-generated keys (e.g. Identity column) and no key value has been set. I'm having trouble with the "store-generated keys" part. My database was created in SMSS, and my table has an Id column of type uniqueidentifier, not null. It is the primary key. But how do I tell SMSS it should be store-generated? And will C# find out about that

How can I retrieve first second and third word of a String in SQL?

由 老子叫甜甜 提交于 2020-02-29 10:02:11
问题 I need a query which would extract the first second and third word of a string. I have approximately 5 words in each row and I need only the first three words out of 5 in the same row (1 row). Example "ATV BDSG 232 continue with other words". I need only the first three words together in one row (in the same row) like "ATV BDSG 232" as a first row. The table has about 1000 rows and at the end of it I should have 1000 rows again but each row should contain only the first three words of the

Can SSMS QueryBuilder use multiple databases in Design View?

由 走远了吗. 提交于 2020-02-22 06:28:09
问题 Can SSMS QueryBuilder somehow support multiple databases in Design View? How could they not let you select the database for the Add tables dialog? These are even on the same server and same SQL Instance. Is there something I'm missing with the Query Builder? Is there another inexpensive UI friendly tool that allows building cross database queries? I want something easier for myself (C# developer not DBA) as well as the other not quite so techy folks around here to use. 回答1: You can't choose

安装SQL sever时加载不全的问题

由 跟風遠走 提交于 2020-02-20 07:33:34
刚开始安装SQL sever的阶段非常顺利，直到打开SSMS时出现了问题。在打开SSMS时，其他同学的的SSMS就会自动跳出连接的一个窗口，而我的基本上就是一个空屏，而且很多地方加载不出来。导致在这个地方浪费了很多时间查阅资料，而网上的资料也基本没有先相关的回答，类似的就是几个闪退的，而我的SSMS并不是闪退，而是加载不全，这是由本质上不同的。在多次尝试之后，我选择了删除SSMS重新安装。但奇怪的是SSMS重新安装也并没有解决问题，打开之后还是加载不完全。最后实在没办法了，我把SQL sever也删掉重新安装。就在这时发现了问题的所在，就在我重新安装的时候，出现了： 提示Microsoft visual c++2017 X64 Minimum Runtime 14.10.25008需要修复 这个错误，我通过查阅资料知道了需要进入控制面板-程序，找到 Microsoft visual c++2017 X64 14.10.25008 右键更改，进行修复，这是一个文件出了问题，需要对其进行修复，最终成功打开SSMS。 之后遇到的问题则是一些常见的问题，即sa登陆错误的问题，老师也给出了解决的方案： https://blog.csdn.net/zhanghan18333611647/article/details/50450183 现在已经成功使用sa账户登录本地数据库服务器
