Simplest ConnectionString For Local SQL Server Express

Configured nothing in SQL Server or the database (DRRSandBox). Just added new one and went. As it uses SSPI (Integrated Security), it authenticates using local user account which by default has access to database.

    <add name="PollConnectionString"
 connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=DRRSandBox;Integrated Security=SSPI"
       providerName="System.Data.SqlClient" />


How to import/export SQL tables, functions and stored procs with SQL Management Studio 2005

  • In Microsoft SQL Server Management Studio Express, expand the databases.
  • Right-Click on the database containing objects you want to copy to another database
  • Click on Tasks, then Generate Scripts… This will open up the Script Wizard, which is pretty much self-explanatory:
    • Select the database (which should be pre-selected for you),
    • Select Options (first time around you might just accept the default selections),
    • Choose the Object Types you want to script (Stored Procedures, User Defined Functions, etc),
    • Select the specific objects to be scripted,
    • and finally specify where to output the script (choose Script to new Query Window for convenience).
  • Once completed, return to the Query Window with the scripted objects.  Change the USE directive (the first line) to point to the destination database (e.g., USE [Northwind]), and execute the script.
