I have a some long scripts that have variables at the very top. When I want to run only part of the script with a variable included, what is the best way to do this...are there other options besides:
- Copy/pasting the declare variables (but this requires me to comment them in/out all the time)
- Just changing the variable to be hard-coded (but I'm concerned that I'll forget to change them back)
So, is there a way to highlight separately the parts I want to run...or maybe something else entirely?
This question is for SQL Server 2008
All the other answers are fine if you can/want to make functional modifications to your script, but if you would rather avoid that, as I suspect, the way I usually do what you are talking about is by block-commenting the parts I want to skip:
So I just change this:
DECLARE @variables; Some Code I want to skip this time; Some Code I want to execute this time; Maybe some more code I want to skip this time;
DECLARE @variables; /* Some Code I want to skip this time; */ Some Code I want to execute this time; /* Maybe some more code I want to skip this time; */

Sometimes I wrap portions of the code inside
BEGIN...END blocks so that I could expand and collapse them inside SSMS. Turns out that you can prefix a block with an
IF 0 = 1 so that it does not execute. Expanding on this idea, you could do this:
-- variables DECLARE @p1 INT = 123; DECLARE @p2 INT = 456; -- which block to run DECLARE @block AS INT = 1; IF @block = 1 BEGIN SELECT 'statement block 1' END IF @block = 2 BEGIN SELECT 'statement block 2' END
Using SQLCMD to Execute Multiple SQL Server Scripts, One of the big challenges is having to collect data from each of the And best of all, once it is setup you can even use it on SQL 2000 and SQL 2005 servers. How to setup and use a SQL Server alias), but I wouldn't recommend to all desktops by using a script, but again I wouldn't recommend using it� The easiest way to do this is to use code of some type. T-SQL isn’t going to work because we need these to run asynchronusly and not synchronously (all at the same time not one after the other) and T-SQL doesn’t have that option. You could create a bunch of agent jobs but again, huge pain when you get past a small number of queries at once.
I tend to use a special variable that I call
@debug, but you can call it what you want. When I'm debugging, I'll use it to set variables, raise status messages (disguised as error messages), and that sort of thing. Then I only need to remember to reset that one value when I'm finished.
DECLARE @var1 INT, @var2 VARCHAR(25), @var3 BIGINT, @debug TINYINT, --Indicator that I'm in debug mode @msg VARCHAR(50); --Custom message text placeholder SET @debug = 1; IF @debug = 1 BEGIN SELECT @var1 = 1, @var2 = 'Hello World', @var3 = 12; END; SELECT @var1, @var2, @var3; IF @debug = 1 BEGIN SET @msg = 'Step 1 Complete' RAISERROR(@msg, 1,0) WITH NOWAIT END;
Top 10 SQL Server Management Studio (SSMS) Tips and Tricks , One script builds the database, another builds the tables, etc. Is it possible to concatenate these scripts together and execute them with a single call to SQLCMD? How is it that SQLCMD knows to execute CREATE_TABLES.sql before I create a DB as part of unit test setup and instead of calling� We have this requirement where we want to execute multiple .sql files one after the other. These scripts file names keep changing. So calling them individually by name wouldn't help.
Use conditionals. See @RunOne and @RunTwo for explanation.

Just building on Salman's answer (+1).
This twist will allow for a block range rather than just one at a time.
