问题 I am writing few Azure Functions script that reads and write from/to an internal database and display relevant information into a webpage.

问题 In SQL Azure, I have a table more or less set up like this, with two computed columns ( IsExpired and IsDeadlineExpired ) that simply compare non-nullable datetime columns to the current time: CREATE TABLE [dbo].[Stuff] ( [StuffId] int NOT NULL IDENTITY(1,1), [Guid] uniqueidentifier NOT NULL, [ExpirationDate] datetime NOT NULL, [DeadlineDate] datetime NOT NULL, [UserId] int NOT NULL, [IsExpired] AS CAST((CASE WHEN [ExpirationDate] < GETUTCDATE() THEN 1 ELSE 0 END) AS bit), [IsDeadlineExpired]

问题 We are about to implement the Read portion of our CQRS system in-house with the goal being to vastly improve our read performance. Currently our reads are conducted through a web service which runs a Linq-to-SQL query against normalised data, involving some degree of deserialization from an SQL Azure database. The simplified structure of our data is: User Conversation (Grouping of Messages to the same recipients) Message Recipients (Set of Users) I want to move this into a denormalized state,

Entity Framework Many-to-Many Clustered vs. Nonclustered Index

由 佐手、 提交于 2019-12-09 16:01:24
问题 I designed an entity data model with two entities between which there exists a many to many relationship. When I auto-generate SQL code to generate the database for this model, it has generated a table (two columns) to keep track of this many-to-many association. However, this table has a PRIMARY KEY NONCLUSTERED on both columns. Since I want this to work on SQL Azure which doesn't like tables with only nonclustered indices, I was wondering whether there is a good way of telling the code

How to use SqlAzureExecutionStrategy and “Nolock”

由 穿精又带淫゛_ 提交于 2019-12-09 05:34:58
问题 To deal with SQL timeouts I'm trying to use SqlAzureExecutionStrategy (https://msdn.microsoft.com/en-us/data/dn456835.aspx) The problem I am running into is it prevents "user initiated transactions" which seem to be the recommended way to implement "with (nolock)" in EF (http://www.hanselman.com/blog/GettingLINQToSQLAndLINQToEntitiesToUseNOLOCK.aspx, NOLOCK with Linq to SQL). example code public AspnetUser GetAspnetUserByUserName(string userName) { using (var tx = new TransactionScope

问题 How can I calculate the current size of a SQL Azure Database? (Not the maximum size limit) Several places (like this) suggest using this sql: SELECT SUM(reserved_page_count) * 8192 FROM sys.dm_db_partition_stats However when executing this as the Administrator login I get this error: Msg 297, Level 16, State 1, Line 1 The user does not have permission to perform this action. 回答1: This is probably because you're running the query on the master database. If you're using SQL Server Management

问题 back-story: We mainly use AWS for everything (hosting, database, notifications, etc.). Now, I'm looking at moving the database side to SQL Azure since we've been getting crazy bills on AWS RDS.

In the past, ELMAH (this specific implementation: https://github.com/alexanderbeletsky/elmah.mvc) worked flawlessly in the past. current situation: I just created a new DB in SQL Azure and noticed
