Finding disk free space and other file level information for SQL Files

Leave a comment Posted by on March 13, 2012

Recently a friend of mine, Rahul Soni in his blog wrote a .Net code to retrieve the file information and other drive information for all SQL Server files.

While discussing this, he wanted to know if this can be done using T-SQL or not, and so the blog article follows.

Most of the file level information can be retrieved from the catalog View Sys.Master_files. To run queries against this view and see the records, the user would need the following permissions

  • CREATE DATABASE
  • ALTER ANY DATABASE
  • VIEW ANY DEFINITION

The catalog view returns information about all the files for all the databases present in SQL Server. Details about the view can be found in SQL Server Books Online.

Additionally, to find the free space information on the Drives, I used to xp_fixeddrives extended stored procedure.

Included below is the code for the stored procedure which I wrote to get this information

   1: USE [master]

   2: GO

   3: /****** Object:  Stored Procedure [dbo].[usp_getFileinformation]    Script Date: 03/13/2012 20:13:15 ******/

   4: SET ANSI_NULLS ON

   5: GO

   6: SET QUOTED_IDENTIFIER ON

   7: GO

   8: ALTER procedure [dbo].[usp_getFileinformation]

   9: As

  10: create table #fixeddrives

  11: (

  12: Drive varchar(2), 

  13: FreeSpaceMB int

  14: )

  15:  

  16: insert into #fixeddrives(Drive,FreeSpaceMB) exec xp_fixeddrives

  17: select  

  18: DB_NAME(database_id) As DatabaseName, type_desc as FileType, 

  19: name as [FileName], physical_name as FileLocation, 

  20: (size*8)  as CurrentSizeInKB, 

  21: case    max_size

  22:      when -1 then null

  23:      else max_size

  24: end As MaxFileSize,

  25: Case  

  26:     when is_percent_growth = 1 then CAST(growth AS varchar(5)) + '%'

  27:     else CAST(growth AS varchar(5)) + ' MB'

  28: End FileGrowth,

  29: SUBSTRING(physical_name, 1,1) As Drive

  30: into #temp from master.sys.master_files

  31:  

  32: select t.DatabaseName, t.FileType, t.FileName, t.FileLocation, t.CurrentSizeInKB, t.MaxFileSize,t.FileGrowth, 

  33: fd.FreeSpaceMB As FreeSpaceOnDrive_MB

  34: from  #temp t

  35: inner join #fixeddrives fd on fd.Drive = t.Drive

This stored procedure returns the following information.

Uploading multiple Reports to the Report Server using .Net

Leave a comment Posted by on March 8, 2012

Continuing the series on Programming for Reporting Services, we will see how to upload multiple reports (*.rdl) files present in a folder, to the Report Server. While this can be done using Report Manager (uploading the reports one-by-one), this obviously is not an efficient way of doing it. In this post, we will see how we can automate the task using .Net.

The code, here assumes that all the *.rdl present in a file system folder would be uploaded to the same Report Server folder. if you require to add reports to multiple folder, then I suggest you create a folder hierarchy, to replicate your Report Server folder hierarchy.

For the purpose of this post, I have created the below mentioned folder hierarchy. Each folder contains some report, which needs to be uploaded to the report server. The reports would be uploaded to a similar folder hierarchy on the Report Server. If the folders do not exists on the Report Server, it would be first created and then the report uploaded.

Each of this folders contain some RDL file, which needs to be uploaded to the Report Server. I have created a Console Application for this purpose.

The First step would be create a method to iterate through the folder structure and read the RDL files.  Then we would need a method read the RDL files and get the report definition. This can be done using one of the IO stream classes in .Net. In my console Application, I have added a C# class named ReadReportDefinition.cs. Code included below.

   1: public static class ReadReportDefinition

   2:     {

   3:         public static void IterateFolderHierarchy(string folderpath)

   4:         {

   5:             ConfigureReports cr = new ConfigureReports();

   6:             string connectionString = "data source=." + ";Initial Catalog=PowerSaverLogs";

   7:             cr.UploadDataSource("PowerManagementDataSource", "SQL", connectionString);

   8:             try

   9:             {

  10:                 DirectoryInfo dir = new DirectoryInfo(folderpath);

  11:                 try

  12:                     { 

  13:                         DirectoryInfo[] subdirectories = 

  14:                                     dir.GetDirectories("*", SearchOption.TopDirectoryOnly);

  15:                         byte[] ReportDefinition = null;

  16:                         foreach (DirectoryInfo Dir in subdirectories)

  17:                         {

  18:                             cr.CheckReportServerFolder(Dir.Name);

  19:                             FileInfo[] ReportFiles = Dir.GetFiles("*.rdl");

  20:                             foreach (FileInfo file in ReportFiles)

  21:                             {

  22:                                 FileStream stream = File.OpenRead(file.FullName);

  23:                                 ReportDefinition = new Byte[stream.Length];

  24:                                 stream.Read(ReportDefinition, 0, (int)stream.Length);

  25:                                 stream.Close();

  26:                                 cr.UploadReports(Dir.Name,ReportDefinition, file.Name.Substring(0, (file.Name.Length - 4)));

  27:                                 ReportDefinition = null;

  28:                             }

  29:  

  30:                         }

  31:                 }

  32:                 catch(System.IO.IOException E)

  33:                     {

  34:                         Console.WriteLine("System Exception Message" + E.Message);

  35:                     }

  36:                 

  37:             }

  38:             catch(System.IO.DirectoryNotFoundException e)

  39:             {

  40:                 Console.WriteLine("System Exception Message" + e.Message);

  41:             }

The next step, would be to add a reference to one of the Reporting Services endpoints, and then dynamically binding it to the Report Server, where the reports needs to be uploaded. For information about, how to add a reporting service endpoint and dynamically bind it to a Report Server, click here.

The next step, is to create a class or methods to call the ReportingService2010 endpoint (this is what I am using in my code) and perform the required actions. In this case, I created a new Class “Configure Reports” to perform the desired operations.

This class has 3 methods, and the constructor. In the constructor, I dynamically bind the endpoint to my Report Server instance.

  • CheckReportServerFolder: Checks if a particular folder exists on the report server on not. This uses the ReportingService2010 Listchildren method.
  • UploadReports : Uploads reports to the Report Server. This function calls the ReportingService2010 CreateReport method.
  • UploadDataSource: To upload the datasource to the report server. Uses the ReportingService2010 CreateDataSource function.

  96: }

Once the classes are in place, all we need to do is call them in the application main function.

   1: class Program

   2: {

   3:     static void Main(string[] args)

   4:     {

   5:         Console.WriteLine("Enter Report File Root Directory");

   6:         string folderpath = Console.ReadLine();

   7:         ReadReportDefinition.IterateFolderHierarchy(folderpath);

   8:         Console.ReadLine();

   9:     }

  10: }

Dynamically binding a Web Service reference to a Report Server Instance

3 Comments Posted by on March 4, 2012

One of the most important aspect of SQL Server Reporting Services, which makes it stand out amongst competition is its extensibility. If you know .Net programming, then you can almost anything with Reporting services. In this series of posts I would be talking about some things which can be done with .Net and Reporting Services.

Typically speaking, .Net with Reporting Services can be used to create any of the following.

  • .Net Applications (console, UI bases) to automate SSRS tasks.
  • Reporting Services extensions (data, security, delivery etc.) to be used with Reporting Services.
  • Reference libraries to be used directly with the Reports in Reporting Services.
  • .Net code to (web service, Forms application) to consume Reporting Services Reports.

In this post, I would be talking about how to dynamically bind a report server instance using a web service reference.

Reporting Services Web service provides a SOAP over HTTP interface for communication with the Report Server. It provides two endpoints, one for execution and another for management. The most important thing, when creating an application for SSRS is to the add the Reporting services proxy class to the project to the class. This can be done using one of the two ways.

Once you have added the web service reference, using any of the two methods described above, the most important thing is to dynamically bind the web service to a Report Server instance.

To dynamically bind the web service to any Report Server of your choice.

  • First create an instance of the SSRS web service, which was added to the project. For example, if you added the ReportService2010 endpoint, create an object for the same.
  • Set the URL property of this object to the desired Report Server web service URL.
  • Define appropriate security credentials.
ReportingService2010 rs = new ReportingService2010();

rs.Url = "http://localhost/reportserver/ReportService2010.asmx";

rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

To make sure that the URL property is recognized by the compiler, you would need to add the following reference to your code.

using System.Web.Services;

At this point, we can call any method defined in the Web Service and perform the desired operation.

In the next post, I will talk about, creating an Application, which can upload, all the .RDL files present in a folder to a report server.

Adding a Reporting Services Web Reference to .Net application

4 Comments Posted by on March 4, 2012

In an earlier post, I had talked about adding a Reporting Services Proxy class using WSDL.exe. In this post, I would talking about adding a Reporting Services Web Service reference to your .Net Application.

As mentioned in the earlier post, SSRS web service provides interface for communication with the Report Server. In order to use the methods exposed by the Web Service, a reference to the Web Service needs to be added to the Visual Studio project. Depending on the requirement, a reference can be added for any of the reporting services endpoints.

  1. ReportService2005
  2. ReportService2006
  3. ReportExecution2005
  4. ReportService2010 (to be used with SSRS 2008 R2).

In order to add, a web service reference to your project, follow the steps provided below.

In solution explorer, right click on the project node and select “Add Service Reference”

image

On the Add Service Reference Window, click on Advanced. This would open the “Service Reference Setting” window. On the Service Reference Setting window, click on “Add Web Reference”.  On the Add Reference window, in the URL section, provide the complete asmx URL for the Reporting Service endpoint which needs to be used. For example, I would be using the ReportService2010 endpoint. Click on Go.

image

When you click on go, the web service reference would be resolved, and the methods available in the web service would be displayed.

In the Web Service Reference name, you can provide any name of your choice, and click on add reference. This would add the desired endpoint reference to your project.

At this post, we have added a web reference to the project. In a next post, I will talk about how to dynamically bind the reference or the proxy class to a Report Server.
