Now we need to enter a value for the Table_array argument. The value of “A11” is inserted into the first argument. Which piece of information from the database, associated with the unique identifier, do you wish to have retrieved for you?.What unique identifier are you looking up in the database?.You can think of this box as the function asking us the following questions: The Function Arguments box appears, prompting us for all the arguments (or parameters) needed in order to complete the VLOOKUP function. The system would return us a list of all lookup-related functions in Excel. To find the one we’re looking for, we could type a search term like “lookup” (because the function we’re interested in is a lookup function). This is found by first clicking the Formulas tab, and then clicking Insert Function:Ī box appears that allows us to select any of the functions available in Excel. We need to locate the list of all available functions that Excel has to offer, so that we can choose VLOOKUP and get some assistance in completing the formula. So that’s where we write the VLOOKUP formula: in cell B11. Where do we want this description put when we get it? In cell B11, of course. To explain further: We are about to create a VLOOKUP formula that will retrieve the description that corresponds to the item code in cell A11. Interestingly, this is the step that most people get wrong. Next, we move the active cell to the cell in which we want information retrieved from the database by VLOOKUP to be stored. In order to test the VLOOKUP formula we’re about to write, we first enter a valid item code into cell A11 of our blank invoice: So, we’ve created our product database, which looks like this: It makes little difference to the VLOOKUP function, which doesn’t really care if the database is located on the same sheet, a different sheet, or a completely different workbook. In reality, it’s more likely that the product database would be located in a separate workbook. That information will be used to calculate the line total for each item (assuming we enter a valid quantity).įor the purposes of keeping this example simple, we will locate the product database on a separate sheet in the same workbook: This is how it’s going to work: The person using the invoice template will fill in a series of item codes in column “A”, and the system will retrieve each item’s description and price from our product database. Let’s create an example of this: An Invoice Template that we can reuse over and over in our fictitious company.įirst we start Excel, and we create ourselves a blank invoice: Each time someone enters a valid item code, the system would retrieve all the necessary information about the corresponding item. Typically you would use this sort of functionality in a reusable spreadsheet, such as a template. If all you need is one piece of information from the database, it would be a lot of trouble to go to to construct a formula with a VLOOKUP function in it. Which of these pieces of information will it pass you back? Well, you get to decide this when you’re creating the formula.

In more recent years, designers have fallen in love with smaller features that conform really well to design workflows and assist them in accomplishing their tasks with ease. It is no surprise that these early UX practices were present in the development of a system that was respected for it’s User Experience. This began Apple’s high level task prioritization for System 7. In this brainstorming session, ideas were written on index cards features that seemed simple enough to implement in the short term (like adding color to the user interface) were written on blue cards, longer-term goals (like true multitasking) were written on pink cards, and “far out” ideas (like an object-oriented file system) were written on red cards. A famous occurrence of this was the “Pink and Blue” meeting that Apple managers held in March of 1988, shortly after the release of System 6. It included a drastically improved user interface and functionalities, which were developed through UX processes that Apple was putting into place before most companies even knew what UX was. User ExperienceĪpple’s System 7 (released in May of 1991) was considered to be much more user friendly than Microsoft’s Windows 3.1 (released in April of 1992). In this respect, the designers that I spoke with felt that Apple has always seemed to respect the design community more than Microsoft. In more recent times, Apple has demonstrated the desire to include classic typefaces in their OS, while Microsoft has continually commissioned “knock-off” typefaces like Arial (from Helvetica) and Segoe (from Frutiger). The Mac was also the first computer with multiple typefaces built into the OS. The basic idea is that Windows renders for readability (resulting in a sharper type style), while Mac OS renders for visual appearance (resulting in style more similar to what you might see on a printed page). But in the past, Microsoft and Apple took somewhat different approaches to how they chose to render fonts, and it made a pretty big impression on designers. In conclusion, Standalone SQL Agent is a good replacement for SQL Server Agent in Express edition and, while it suffers from some limitations, I still believe it’s the best option available. If everything works as expected, you can restart the SQL Server Express instance and the Standalone SQL Agent service will restart as well. Get-ServiceAcl "Standalone SQL Agent" | select -ExpandProperty AccessĪfter running this script from an elevated Powershell instance, you can test whether the startup stored procedure has enough privileges by invoking it manually. # Apply the modified ACL object to the service: However, SQL Server Express is still a DBMS robust enough to support small applications, with a wide variety of management (Windows Authentication. In summary, we can consider SQL Server Express as a free and 'lite' version of SQL Server Enterprise, due to the limitations of the Express version. $ServiceAcl.AddAccessRule((New-AccessControlEntry -ServiceRights "Start,Stop" -Principal $serviceLogonAccount)) Meet SQL Server Express with Advanced Services. # Add an ACE allowing the service user Start and Stop service rights: $ServiceAcl = Get-ServiceAcl "Standalone SQL Agent" $serviceLogonAccount = $service.StartName # Change to the display name of your SQL Server Express service In order to run it, you need to download the code available at Rohn Edwards’ blog. The following PowerShell script grants the SQL Server service account all the rights it needs. However, you’ll probably notice that the SQL Server service account does not have sufficient rights to restart the service. You can overcome this limitation using a startup stored procedure that restarts the service:ĮXEC xp_cmdshell 'net stop "Standalone SQL Agent"'ĮXEC xp_cmdshell 'net start "Standalone SQL Agent"'ĮXEC sp_procoption = 'startStandaloneSQLAgent' No connection attempt will be made until Sevice is restarted. In the ERRORLOG file you’ll find a message that resembles to this: Error connecting to SQL Instance. When the service loses the connection to the target SQL Server instance, it won’t restart automatically and it will remain idle until you cycle the service manually. If you don’t have a SQL Server 2008 instance available, you can extract the definition of the stored procedure from the source code at CodePlex. I don’t know why this happens: I copied the definition of the stored procedure from a 2008 instance and it worked fine. In the ERRORLOG file (the one you find in the Standalone SQL Agent directory, not SQL Server’s) you’ll quickly find the reason of the failure: it can’t create the stored procedure sp_help_job_SSA. Easy peasy.Īs far as SQL Server 2012 is concerned, the service fails to start when connected to a 2012 instance. The UAC problem during installation is easy to solve: open an elevated command prompt and run the installer msi.
