Dropping SQL Server Locks

The following query can be used to drop the locks on Database objects. It should be used carefully as the false killing of the processes would lead to disastrous issues which would come as chain of issues.

Create Table #Tmp
(
spid smallint,
ecid smallint,
status nchar(30),
loginame nchar(128),
hostname nchar(128),
blk char(5),
dbname nchar(128),
cmd nchar(16)
)

Create Table #TmpLocks
(
spid smallint,
dbid smallint,
ObjId int,
IndId smallint,
Type nchar(4),
Resource nchar(16),
Mode nvarchar(8),
Status nvarchar(28)
)

Insert Into #Tmp
Exec sp_who

Insert Into #TmpLocks
Exec sp_lock

If(Select Count(*) From #Tmp T Join #TmpLocks TL On T.spid = TL.spid Where /*This is for tempdb*/ dbid = 2 And objid In (1, 2, 3)) > 0

Then you can kill the concerned spid with the command :

Kill — The concerned spid

Drop Table #Tmp
Drop Table #TmpLocks

Deferred prepare could not be completed

This is usually an error that is encountered while querying a remote database on a different server instance which says OLEDB provider "SQLNCLI" for linked server "ABCD" returned message "Deffered prepare could not be completed" Msg 8180, Level 16, State 1, Line 1 Statement(s) could not be prepared. This is the way I could rectify, though this is not the lone mistake that gives this error every time. Just set the default to the database that is being querying to the user through which the Linked server is connecting to the database.

Script level upgrade for database 'master' failed because upgrade step 'sqlagent100_msdb_upgrade.sql'

As huge a database grows, that tedious are regular DBA activities become. Besides, a warehouse database, can grow with no bounds to challenge.  There was a patching on one of our databases, SP3 for SQL Server 2008 R2, which was failing due to the error below. As the error says, MASTER the heart of SQL Server  “Script level upgrade for database 'master' failed because upgrade step 'sqlagent100_msdb_upgrade.sql' encountered error 2627, state 1, severity 14. This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the 'master' database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion. Cannot recover the master database. SQL Server is unable to run. Restore master from a full

Incorrect SET Options with Filtered Indexes

Rebuild Index|Create Index|DML on a Table with Filtered Index fails with the error: The following SET options have incorrect settings: 'QUOTED_IDENTIFIER'.

[SQLSTATE 42000] (Error 1934).  The step failed. The Operation above might succeed when its through SSMS. But, would fail when the operation is from a SQL Agent Job. This is because, SQL Agent by default, do not have the SET Options enabled (ON). They are OFF.

Required SET Options for Filtered Indexes The SET options in the Required Value column are required whenever any of the following conditions occur: Create a filtered index.
