Cannot drop database “DataBaseName” because it is currently in use




Last evening I ran into the precarious situation when trying restore a database.

I have cut down a lot of steps to just get to the problem.  By 9.00 pm I had done few database restores at a client and one of the large databases just wouldn’t get restored with the standard error.

Msg 3702, Level 16, State 3, Line 2
Cannot drop database “DataBaseName” because it is currently in use.

I went through the sysprocesses and killed all the active connections but the same message kept popping out all the time. After many attempts and 10 minutes gone I was still at square one.
Tried standard opening and closing management studio ,Stopping sql agent  none would work.

Finally I took the database into single user mode with Alter database set single_user with rollback immediate ( this took about 5 minutes to execute) and created hole load of informational messages in between.
Then dropped the database which took another 5 minutes to take effect.

Create a dacpac To Compare Schema Differences

It's been some time since i added anything to the blog and a lot has happened in the last few months. I have run into many number of challenging stuff at Xero and spread my self to learn new things. As a start i want to share a situation where I used a dacpac to compare the differences of a database schema's. - This involves of creating the two dacpacs for the different databases - Comparing the two dacpacs and generating a report to know the exact differences - Generate a script that would have all the changes How to generate a dacbpac The easiest way to create a dacpac for a database is through management studio ( right click on the databae --> task --> Extract data-tier-application). This will work under most cases but will error out when the database has difffrent settings. ie. if CDC is enabled To work around this blocker, you need to use command line to send the extra parameters. Bellow is the command used to generate the dacpac. "%ProgramFiles...

High Watermarks For Incremental Models in dbt

The last few months it’s all been dbt. Dbt is a transform and load tool which is provided by fishtown analytics. For those that have created incremental models in dbt would have found the simplicity and easiness of how it drives the workload. Depending on the target datastore, the incremental model workload implementation changes. But all that said, the question is, should the incremental model use high-watermark as part of the implementation. How incremental models work behind the scenes is the best place to start this investigation. And when it’s not obvious, the next best place is to investigate the log after an test incremental model execution and find the implementation. Following are the internal steps followed for a datastore that does not support the merge statements. This was observed in the dbt log. - As the first step, It will copy all the data to a temp table generated from the incremental execution. - It will then delete all the data from the base table th...

How to Backup postgres globals without sysadmin permission in RDS

For those of my Friends who are on postgres RDS and require to backup the globas for a rds instance you would soon find it can't perform a backup with pg_dumpall --globals-only.  The default user that gets created along with the RDS postgres instance does not have adequate permission to get through the backup processes. Bellow is the message that you would receive. pg_dumpall.exe : pg_dumpall: query failed: ERROR:  permission denied for relation pg_authid At line:1 char:1 + & 'C:\setup_msi\postgres\bin\pg_dumpall.exe'  -h XXXXXX.cXXXX... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~    + CategoryInfo          : NotSpecified: (pg_dumpall: que...ation pg_authid:String) [], RemoteException    + FullyQualifiedErrorId : NativeCommandError pg_dumpall: query was: SELECT oid, rolname, rolsuper, rolinherit, rolcreaterole, rolcreatedb, rolcanlogin,...
