T-SQL Command Line Arguments

I am currently working on automating the climate chip analysis process. It is a mix-and-match of Python code for the calculations and callable command line scripts to manage the database. To be truly effective, I have had taken advantage of T-SQL’s ability to accept command line arguments (called “scripting variables”(1) by Microsoft). In general you can pass arguments to T-SQL scripts using the following syntax:

USE climate30Year;

SELECT latitude, longitude, month, Tmax
  FROM cru30Year
  WHERE year=$(PARAM);

and then, from the terminal use sqlcmd and the -v switch:

#> sqlcmd -v PARAM ="<value>" -i <scriptName> -S <serverInstance>
