To get all the table details of a specific database in MS SQL Server, use the following query. USE [DATABASE-NAME] SELECT * FROM INFORMATION_SCHEMA.COLUMNS After you run the query use can select individual fields as per your requirement. As of me my requirement is as follows. USE [DATABASE-NAME] SELECT TABLE_NAME, COLUMN_NAME,DATA_TYPE,IS_NULLABLE, ISNULL(COLUMN_DEFAULT,'') AS COLUMN_DEFAULT FROM INFORMATION_SCHEMA.COLUMNS ORDER BY TABLE_NAME To include the length of the column run the following script. USE [DATABSE-NAME] SELECT OBJECT_NAME(c.OBJECT_ID) TableName ,c.name AS ColumnName ,SCHEMA_NAME(t.schema_id) AS SchemaName ,t.name AS TypeName ,t.is_user_defined ,t.is_assembly_type ,c.max_length ,c.PRECISION ,c.scale FROM sys.columns AS c JOIN sys.types AS t ON c.user_type_id=t.user_type_id ORDER BY TableName;

As you must be aware that in any configuration file under Linux OS, there is hundreds of lines, most of them are commented with explanations. Therefore going though such files takes time to locate the line we are looking for. I use the command below to remove all the commented lines and blank lines by combining two commands using pipe '|'. In my case the comments are marked with #. grep -v "^#" main.cf | grep -v "^$" The grep -v "^#" filename will remove the commented line. The grep -v "^$" will remove the blank lines.

Index Rebuild This process drops the existing Index and Recreates the index Rebuild all indexes for the respective table ALTER INDEX ALL ON REBUILD; Rebuild specific indexes for the specific table ALTER INDEX ON REBUILD; Index Reorganize This process physically reorganizes the leaf nodes of the index. Reorganize all indexes for the specified table ALTER INDEX ALL ON REORGANIZE; Reorganize a specific index ALTER INDEX ON REORGANIZE; Recommendation : Index should be rebuild when index fragmentation is great than 40%. Index should be reorganized when index fragmentation is between 10% to 40%. Index rebuilding process uses more CPU and it locks the database resources. SQL Server development version and Enterprise version has option ONLINE, which can be turned on when Index is rebuilt. ONLINE option will keep index available during the rebuilding.

Every time I worked on PHP, I always used include, then later on I wanted to know the difference between include, include_once, require, and require_once. After googling I came to know the difference. include: Includes and evaluates the specified file, throwing a warning if the file can’t be found. include_once: Same as include, but if the file has already been included it will not be included again. require: Includes and evaluates the specified file (same as include), but instead of a warning, throws a fatal error if the file can’t be found. require_once: Same as require, but if the file has already been included it will not be included again.

I used the calendar control from the AJAX toolkit to set a date in its associated asp:textbox control. I wanted the user to only be able to set the date through the calendar control so I made the textbox to read only by setting the ReadOnly property to true. The problem this produces is that readonly controls don’t post back their values in the viewstate thus you lose the value when the user submits the form. The Solution: Leave the textbox control property as ReadOnly = False In the Page Load event set the client side attribute of the textbox with the following: txtDate.Attributes.Add("ReadOnly", "true"); This way the control is included in the postback and the value is preserved but client side the user won’t be able to manually edit it.

In Local devices and resources group box, select more... 5. Then check, Drives That's it folks, now open the My Computer in the remote Desktop that you have just logged in. There you will see your Drives added automatically as Map Network drives. now you can make a file transfer between your laptop and the Remote Desktop Server.

In some network where you have to enter the IP Address of the proxy server to access the internet and you are not able to use the yum command to update your system. You normally put the Proxy Server IP and Ports in your browser setting, but in Linux box that doesnot solve the problem.

Cross browser compatibility struggle is getting upsetting while working with asp:Menu Server Control. Anyhow, It was not rendering/working well with Safari and Chrome. A bit of googling... and I have a solution for this. I have added below small piece of code snippet in my MasterPage's Page_Load event if (Request.UserAgent.IndexOf("AppleWebKit") > 0) { Request.Browser.Adapters.Clear(); } This will tell asp.net not to use an adapter when rendering the menu control. This will work for both Safari and chrome as well because they both use webkit which is how asp.net identifies Safari1Plus. courtesy: http://dotnetslackers.com/Community/blogs/kaushalparik/default.aspx
