   • What is a good access time to a database (SQL)?

     I think it would depend on your needs. Is it for a web server or a desktop application? The amount of data is also important, because reading lots of small records will perform differently than reading a few large records. Access time is also based upon your hardware, software and maybe even some other factors. For example, you can use a database with lightning-fast access, but if your users need to connect to it over a 5 megabit VPN connection, passing through three different proxies and with trafic world-wide, your database would then just be a waste of power. Basically, it's a marketing thing that they're claiming. It's a good product but don't just focus on access time. Make sure you also look at your other needs. Another system might just perform better, even if it has a slower acess time, because it is more optimized in reading it's indices and stuff. So, what do you want, exactly?

   • Access is denied when attaching a database

     Top Answer

     Answered Mar 28, 2018 · 114 votes

     Thank you for all of the comments. Some of you helped to lead me to the answer. Here's what I found:

     It was an NTFS permission problem, and not a SQL problem. Further, it looks kind of bug-like (and it's repeatable).

     The problem: The account that I was using had full control NTFS permissions to the mdf and ldf files. However, it had those permissions through group membership (the Local Administrators group had permissions, and my account is a member of local admins). (I verified the permissions)

     If I try to do the attach, connect to SQL Server as me (where I am in the admins group), it fails with the NTFS problem.

     However, if I grant the same file permissions that the local admin group has directly to my Domain Account, then I can attach with no problems.

     (oh, and yes, I checked the local groups on this machine, and I verified that my domain account is indeed a member of the local admins group).

     So, it looks as though the error occurs because some code (either in SQL Server or Management Studio) checks for the permissions that the user account holds, but it doesn't go so far as to check group permissions that the user account inherits.

     That sounds weird to me, but I can reproduce it over and over again, so I have concluded that it is the answer.

     Update: I reported this as a bug: https://connect.microsoft.com/SQLServer/feedback/details/539703/access-denied-attaching-a-database-when-permissions-are-inherited

     I'd like to add additional info to the answers that were posted.

     Be careful when detaching the database because the windows user you are logged in as becomes the only user with permissions to the .mdf file! The original permissions the .mdf file had which included the user SQLServerMSSQLUser$<computer_name>$<instance_name> and the Administrators account get overwritten by whichever windows user you are logged in as (not sql server user). Boom, all permissions gone just like that. So do as others have said and right click your .mdf file and double check the permissions.

     I ran into this problem because I used SSMS to connect to the database (doesn't matter which sql server account) and detached the database. After doing that my windows user was the only one that had any permissions to the .mdf file. So later on when I tried to attach the db using the sa account, it threw the "access denied" error.

     To keep the original permissions in tact you should take the database offline, then detach, then attach in that order like so:

     USE [master]GO-- kick all users out of the dbALTER DATABASE mydbSET SINGLE_USER WITH ROLLBACK IMMEDIATE GO--- Take the Database OfflineALTER DATABASE mydb SET OFFLINE WITHROLLBACK IMMEDIATEGO--- detach the dbEXEC master.dbo.sp_detach_db @dbname = N'mydb'GO-

   • What is the difference between a lock and a latch in the context of concurrent access to a database?

     From CMU 15-721 (Spring 2016), lecture 6 presentation, slides 25 and 26, which cites A Survey of B-Tree Locking Techniques by Goetz Graefe:

     Locks → Protects the index’s logical contents from other txns. → Held for txn duration. → Need to be able to rollback changes.

     Latches → Protects the critical sections of the index’s internal data structure from other threads. → Held for operation duration. → Do not need to be able to rollback changes.

   Feb 25, 2010 · This sounds like NTFS permissions. It usually means your SQL Server service account has read only access to the file (note that SQL Server uses the same service account to access database files regardless of how you log in). Are you sure you didn't change the folder permissions in between logging in as yourself and logging in as sa?

   Server=.\SQLExpress;

   AttachDbFilename=|DataDirectory|DebugDatabase.mdf;

   For SQLAdminTwo to be able to reattach the database, full permissions on the mdf andldf needs to be granted to either the Database Engine SID NT SERVICE\MSSQLSERVERor the Windows login of the DBA who attempts to reattach the database.
