Monitor SQL Server processes and jobs, view executing SQL query, kill process / job, object explorer, database shrink/log truncate/backup/detach/attach, object version control & compare

Introduction

There is a second article here with the latest version: sqlmonitor.aspx.

It's an open source project, which is hosted at http://sqlmon.codeplex.com/.

It can monitor SQL Server processes and jobs, view executing SQL query, kill process / job, object explorer, database shrink/log truncate/backup/detach/attach, object version control & compare.

It uses C# with Winform and Linq and requires .NET 3.5 (client profile).

The implementation is quick and a little dirty, pretty straight forward, but I try to maintain the logic and get the job done.

Background

Ok, I have to admit that I got bored from time to time so I just want to make something to kill time. It looks like I am reinventing a wheel (duplicating part of SQL Server Management Studio?), mmm, actually, I don't think so. I address something here that does not exist in SQL Server Management Studio at all, at least not in 2008R2.

Functionalities

Object Explorer

In object explorer, you can browse servers, databases, tables, views, functions and stored procedures.

SQLMonitor1.png

//Listing databases   
using (SqlConnection connection = NewConnection)
{
   connection.Open();
   var data = connection.GetSchema("Databases");
   data.AsEnumerable().OrderBy(r => r.Field<string>("database_name")).ForEach((d) =>
   {
        var name = d["database_name"].ToString();
   }
}
Database

For each database, you can see the file paths, database size.

SELECT DB_NAME(database_id) AS DatabaseName, Name AS Logical_Name, _
    Physical_Name, CAST(size AS decimal(30,0))*8 AS Size, _
    state FROM sys.master_files WHERE DB_NAME(database_id) = 'YOUR_DATABASE_NAME' 
Object Search

Well, do you want to search an object across tables/views/functions/stored procedures with wild char? Or do you want to search a phrase or an object that is being used in a function or stored procedure? With SQL Monitor, you can. Simply right click on a database, and choose search.

--search in script
Select s.name, s.create_date AS CreateDate, s.modify_date AS ModifyDate, _
    s.type, c.text from syscomments c left join sys.objects s _
    on c.id = s.object_id where [Text] like '%YOUR_QUERY_HERE%'

--search in jobs
SELECT job_id, name, date_created AS CreateDate, date_modified _
    AS ModifyDate, 'Job' AS type FROM msdb.dbo.sysjobs
Database Backup
--backup a database
BACKUP DATABASE DATABASE_TO_BACKUP TO DISK = 'C:\YOUR_BACKUP_FILE' _
  WITH NOFORMAT, NOINIT,  NAME = N'BACKUP_NAME', SKIP, NOREWIND, NOUNLOAD, STATS = 10
Detach Database
--detach a database
BEXEC sp_detach_db @dbname = 'DATABASE_NAME'
Attach Database
--attach a database
EXEC sp_attach_single_file_db @dbname = 'DATABASE_NAME', _
    @physname = 'C:\YOUR_DATABASE_FILE'
Truncate Log
--truncate database log
DBCC SHRINKFILE ([LOG_NAME] , 0, TRUNCATEONLY)
Shrink Database
--shrink database
DBCC SHRINKDATABASE ([YOUR_DATABASE_NAME])
Set Database Online / Offline
--set database state
ALTER DATABASE [YOUR_DATABASE_NAME] SET ONLINE

ALTER DATABASE [YOUR_DATABASE_NAME] SET OFFLINE
Table

When you choose a database, it will show all tables, each will have spaced used, records, created date and last modified date.
When you select a table, it will show the script of the table, which we do not have in SQL Server Management Studio directly.

--To get table names and records
SELECT 
    [TableName] = so.name, 
    [RowCount] = MAX(si.rows) 
FROM 
    sysobjects so, 
    sysindexes si 
WHERE 
    so.xtype = 'U' 
    AND 
    si.id = OBJECT_ID(so.name) 
GROUP BY 
    so.name
--To get table used space
EXEC sp_spaceused 'TABLE_NAME'
--To get table script
declare @Id int, @i int, @i2 int,@Sql varchar(max),@Sql2 varchar(max), _
    @f1 varchar(5), @f2 varchar(5), @f3 varchar(5), @f4 varchar(5), @T varchar(5)
    select @Id=object_id('YOUR_TABLE_NAME_HERE'), @f1 = char(13) + _
    char(10), @f2 = '    ', @f3=@f1+@f2, @f4=',' + @f3
    
    if not(@Id is null)

View/Function/Stored Procedure

When you choose a database, it will show all views/functions/stored procedures, each will have created date and last modified date.
When you select a view/function/stored procedure, it will show the script of the object.

--To get object script
SELECT DISTINCT o.name, o.xtype, c.text, colid
FROM syscomments c
INNER JOIN sysobjects o ON c.id=o.id WHERE name = 'YOUR_OBJECT_NAME_HERE' ORDER BY colid

Activities

In activities, you can browse/kill currently running SQL Server processes and jobs.

    s.host_process_id AS hostprocess, s.login_name AS loginname, _

Version Control

I got the idea from here: http://www.sqlteam.com/article/using-ddl-triggers-in-sql-server-2005-to-capture-schema-changes.

The basic idea is to capture DDL change events using database trigger, and store them in a table.

To enable version control, select a database, right click, choose "Enable Version Control".

ENABLE TRIGGER [TRG_VERSION_CONTROL_TABLE] ON DATABASE

Right now, it can only view and compare versions. In the next version, it will be able to rollback to a certain version.

To compare verions, I use A Generic, Reusable Diff Algorithm in C#.

SQLMonitor6.png

For version comparison, it can automatically sync two text boxes side by side.

Besides comparing version, it supports to compare two SQL scripts.

Right click on object script text box and choose "Compare" or create new query window and right click and choose "Compare".

Points of Interest

To Do

  1. Activities capture & alert notifications
  2. Analysis

Well, initially I developed this application for easier management of the complicated databases in our system. There are over 2000 stored procedures, with some crazy tables holding more than 20 billion records each table. Frequently, we need to modify our stored procedures and we need to search script and control the versions. Later on, I think that maybe there are other database developers who would like to use this application, so I made it open source.
