Should I catch and wrap general Exception?

Question

Can following code be considered as a good practice? If not, why?

try
{
    // code that can cause various exceptions.

You can use ellipses too.

   catch (...) 
   {
        // catches all exceptions, not already catches by a catch block before
        // can be used to catch exception of unknown or irrelevant type
   }

Except this what you can do is nested try-catch

try
{
    //some code which is not for database related 
    try
    {
      //database related code with connection open
    }
    catch(//database related exception)
    {
        //statement to terminate
    }
    **finally()
    {
        //close connection,destroy object
    }**
}
catch(//general exception)
{
    //statement to terminate
}

According to me, this would help you to get more concise idea of your error type.
