Create directories through T-SQL

In a recent task i was connected to SQL Server through SSMS and had no OS access. To configure the automatic backups i was required to create couple of directories on the disk. So without having OS access i had to create directories by using T-SQL. Following is the command that i used to create ‘D:DBBackupsDBDigger’

EXEC master.dbo.xp_create_subdir 'D:DBBackups_DBDIgger'
GO

Get total size of log file along with used space percentage for each SQL Server database

Always there exists a single log file for each SQL Server database. Log file keeps growing when in full or bulk logged recovery model. DBAs implement strategies to manage the log file size. There are two aspects of log file size.

  • One is log file size that it captures on disk and is shown at OS level.
  • Second aspect relates to filled part of over all log file.

Suppose there is a log file with size 20 GB on disk then it is quite possible that it is filled with only 1 GB log and rest of 19 GB is empty. SQL Server will keep populating the remaining part unless it is full and then will claim more size according to file growth settings.
It is a basic requirement to have an idea of log file and its used space. Following is a very simple way to get this information. You may also insert the information into a table on daily or weekly basis and may process alerts for these.

DBCC SQLPERF (LOGSPACE)
GO

Get total size of log file along with used space percentage for each SQL Server database

As a result we have Database name, total log file size as well as the filled log space percentage. Last column status is always zero.

Scripts for SSRS reports usage analysis

Here are some handy and useful scripts that may be used to analyze the report usage of your SSRS report server. All these are select scripts and are using NOLOCK hint. So feel free to add filters and customize according to your specific requirements.
To get the last Time a Report was generated we have following script. Further filters may be applied if required.

 SELECT DISTINCT C.NAME AS [Report Name]  
   ,MAX(EL.TIMESTART) AS [LAST START TIME]  
 FROM REPORTSERVER.DBO.EXECUTIONLOG(NOLOCK) EL  
 INNER JOIN REPORTSERVER.DBO.CATALOG (NOLOCK) C ON EL.REPORTID = C.ITEMID  
 GROUP BY C.NAME  
 ORDER BY C.NAME  

If you want to analyze that how many reports were viewed on a specific day then we have following script. It generates report usage Stats by Date. It is advisable to insert the name of the account that runs SSRS. The reason is that if you have a report that is run off of cache or has subscription, the counts will show here. So if you want to see reports that have been run by users only then filter out the account that runs the SSRS service.

SELECT CONVERT(VARCHAR(25), TIMESTART, 101) AS [SPECIFIC DATE]  
   ,COUNT(*) AS [Gneerated Number]  
 FROM REPORTSERVER.DBO.EXECUTIONLOG(NOLOCK)  
 --WHERE USERNAME NOT IN  
 GROUP BY CONVERT(VARCHAR(25), TIMESTART, 101)  
 ORDER BY CONVERT(VARCHAR(25), TIMESTART, 101) DESC  

Get the report server usage during the hours.

SELECT DATEPART(HOUR, TIMESTART) AS HOUR  
   ,COUNT(*) AS [Gneerated Number]  
 FROM REPORTSERVER.DBO.EXECUTIONLOG(NOLOCK)  
 --WHERE USERNAME NOT IN  
 GROUP BY DATEPART(HOUR, TIMESTART)  
 ORDER BY DATEPART(HOUR, TIMESTART)  

To get the reports generated by users we have following script.

SELECT EL.USERNAME  
   ,C.NAME  
   ,COUNT(1) AS [Gneerated Number]  
 FROM REPORTSERVER.DBO.EXECUTIONLOG(NOLOCK) EL  
 INNER JOIN REPORTSERVER.DBO.CATALOG (NOLOCK) C ON EL.REPORTID = C.ITEMID  
 GROUP BY EL.USERNAME  
   ,C.NAME  
 ORDER BY EL.USERNAME  
   ,C.NAME
