MSSQL – Two common issues while restoring a backup and it’s solutions

There are two most common issues while restoring the database (usually ending in .bak format).

First error
System.Data.SqlClient.SqlError: The backup set holds a backup of a database other than the existing ‘user_database‘ database. (Microsoft.SqlServer.Express.Smo)

Solution for First error

On the Restore page that loads up, make sure that the Destination for restore has the database you want to restore and in the Source for Restore, choose From device: And browse by clicking [..] and Add the file location there, the location where your database backup resides. You may need to browse the backup. If you get permission denied, copy the bak in the MSSQL folder.

Attaching the database backup file

Restore it. Make sure that the Restore Checkbox is selected. And Click OK. And get ready for the error

Here comes the first errorSystem.Data.SqlClient.SqlError: The backup set holds a backup of a database other than the existing ‘user_database’ database. (Microsoft.SqlServer.Express.Smo)
And the solution is to go to Options -> Overwrite Existing Database . But if you aren’t so lucky, you will be welcomed by another error as seen below. where it’s solution is to edit the path from D:\ to C:\ or whichever Drive, where your MSSQL is installed.

System.Data.SqlClient.SqlError: Directory lookup for the file “D:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\user_database.mdf” failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.Express.Smo)

Both THE Solutions are in a single screen shot. The final screenshot

HTTP 405: The HTTP verb used to access this page is not allowed

On an html page, one of our customers was getting this issue. Despite asking him to change the extension to .asp, he insisted to have html extension and still process the HTTP verbs, where it is POST method here.

Situation becomes like this a static page wants to be read a dynamic page and process the values obtaining from POST method. Solution is to make the .html read as .asp with asp dll, just like we do html parse as php in Linux boxes Here are the steps to do it on a Windows 2003 machine

1. Start –> Run –> inetmgr
2. Websites –> website/domain name in question
3. Right Click on the domain –> Properties –> Home Directory –> Configuration
4. In the tab Mappings –> Add an extension for .html and .htm , if it is missing (most cases it will be missing) and edit to add all verbs (POST, GET, HEAD are needed)
5. Fields to be added are as below,

Executable : C:\WINDOWS\system32\inetsrv\asp.dll
Extension : .html
Limit to : GET,HEAD,POST,TRACE

And Click Apply, OK All is well !!
