Tools and Processes for “Fitting it all in”

Most data professionals I’ve met work in two modes: we plan for our day, and we react to the situations around us. I’m staring at my list of things that I need to do today right now, which is my planned work. Of course, I have no idea how much of that will really get done – it’s optimistic to be sure. On the other hand I have several systems I manage, and at any moment one of them or the people that interface with them may “change state” such that I need to give them some attention.

So how do I meld the two? Sometimes it can be quite difficult. I’m constantly working through my list in my mind, re-arranging what I’m focusing on based on what I perceive as the highest need. There are, however, some tools that I use each day to help me manage the workflow.

I use Outlook for tracking everything, since it has a task list (my primary tracking), a calendar, mail and so on. Also I can share the information, it’s on-line so I can see it anywhere, and I can even take it offline onto the plane this week when I fly out of town.

For the “ad-hoc” work, I rely on a script library, which I keep as SQL Server Management Studio projects. I keep those scripts and projects backed using Microsoft Live Mesh, which synchronizes those files (along with a few other critical files and my IE Favorites) across not only my laptop and primary systems, but even with my Virtual Machines.

Also for my SQL Server systems I use the Standard Reports I’ve blogged about here. I also use Greg Larsen’s Database Dashboard, and a series of PowerShell scripts that work across my systems, alerting me to any problems. Of course I’m using SQL Server Agent Jobs quite a bit, and I also use Alerts and some Perfmon automation for my monthly baselining.

So – is this your experience as well? Do you get driven by both planned and unplanned work? What tools and processes do you use to keep it all straight with your SQL Server Instances?

Code that Writes Code

I have scripts that re-create my databases for testing and development purposes. But sometimes I want to take the data from a set of tables and move it as well – I could use SSIS, or a SELECT INTO statement, but what if I want to “re-set” the data to a point in time? In other words, load it with some “base data”?

I thought this might be a good place to demonstrate “code that writes code”. No, it isn’t that big of a deal – most DBAs know how to do this, but in the interest of those who don’t, I thought I would share.

So the end result I want in this case is to have a bunch of INSERT statements that contain my base data from a table where that data already exists. I could script out the table from SSMS and use the replacement parameter feature to fill out each record individually:

I have a table in one of my databases that I right-clicked to show the INSERT statement:

-- Person

INSERT

INTO [WAVS].[dbo].[Person]

([PersonName]

,[Street]

,[CityStateZip]

,[PersonType])

VALUES

(<PersonName, varchar(150),>

,<PersonStreet, varchar(100),>

,<PersonCityStateZip, varchar(255),>

,<PersonPersonType, varchar(100),>)

I can use the CTRL-SHIFT-M keys to replace the VALUES part with the values I want.

But I already had a copy of that “base” data before I turned the database over to the testers. Before I give it to them, I run code like this on each table – this one is for the Person table above (note that there should only be two lines here):

SELECT

'INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (' + CAST([PersonID] AS VARCHAR(5))+ ', ''' + [PersonName]+ ''', ''' + [Street]+ ''', ''' + [CityStateZip] + ''', ''' + [PersonType] + ''')'

FROM

[WAVS].[dbo].[Person]

When I run this code, I get these statements:

INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (1, 'Buck Woody', '123 Here Street', 'Covington, WA 98042', 'Vet')
INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (2, 'Jane Doe', '231 Function Ave', 'Redmond, WA 98052', 'Vet')
INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (3, 'Diane Wilson', '34251 Appt 3 7th Street', 'Seattle, WA 98061', 'Vet')
INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (4, 'John Kelso', '89734 Country Lane', 'Covington, WA 98042', 'Farmer')
INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (5, 'Marjorie Christian', '9893452 Changein Lane', 'Maple Valley, WA 98072', 'Farmer')
INSERT INTO [WAVS].[dbo].[Person] ([PersonID], [PersonName], [Street], [CityStateZip], [PersonType]) VALUES (6, 'Joanne Lister', '98904 Mapelwood Drive', 'Spokanne, WA 98045', 'Zoo Worker')

All I have to do is copy those statements into my “initialization” scripts just after the table creations, and then I can run them at will to create my new database (I know I can take a backup – I have reasons for not doing that).

There are two keys for writing code that writes code: The first is to simply use the single tick (') to write out what the end code should say (INSERT INTO, in my case) and then to use multiple ticks (''') when you want the code to contain the ticks themselves. This “escapes” the characters so that you can embed them. If you use SSMS to write your queries, the color coding will look as mine does above. You’ll also need to remember to CAST or CONVERT any data types that don’t concatenate (+) together well. In my case I had to CAST an integer value – but that’s OK, since it is only printing to the screen and I don’t include the ticks, the INSERT works fine.

You can use this method not only with INSERTS, but with lots of operations. And you can also even fire off the code once you create it – but that’s another post :)
